good ventilation to cool the unit.

HTR-3 Remote Control

The supplied remote control is an eight device "universal" IR remote controller with back-lit gum-drop buttons. Use the remote for full control of the Processor/Receiver, plus various AV sources and displays via the extensive library of device codes. A complete list of codes is available on our Knowledge Base at: audiocontrol.com/knowledge-base/. Search "program htr-3".

The remote is also a "learning remote" which means that you can capture the codes of your existing remotes if you find that the library does not contain the codes for your device.

Many of the buttons have more than one function, depending on which device/source or mode you are using the remote in. We will ease into the complexities of the remote's multi-function modes after a quick description of the basic features below.

Please note: Device code library, instructions on programming the remote and more control and automation documents are available on our Knowledge Base at: audiocontrol.com/knowledge-base/

Multifunction Remote

Remote Features

Multifunction Remote - the HTR-3 can control up to 8 source devices! It automatically configures to the mode of control of the source selected by the source buttons.

Learning - The remote can be configured to control each of your source devices by pressing the number "1" button and one of the 8 source buttons at the same time, and then entering the 3-number control code for your source, such as the CD player, or Cable box.

LED Indicator

LED indicator - This top red LED will blink when a key is pressed. It will also blink multiple times when a device code is input for programming or signal the beginning and end of a programmed sequence.

Back-lit Keys - The keys are back-lit to make it easy for you to control your devices in a dimly lit room.

Low Voltage Indicator - The red LED will flash 5 times after a normal key press to tell you that new batteries are needed.

Other useful items

Time Out - After entering into the programming state of the remote, 30 seconds after the last button is pressed, the remote returns to normal operation.

Stuck Key Time Out - If the remote has slipped into the cushions of your couch and a button is pushed in for more than 30 seconds, the remote will stop sending IR information to conserve the battery. It will resume normal operation after the button has been released.

General Functions

The Device or Source keys allow you to switch between the various inputs on your Processor/Receiver. After pressing the device key, the remote actually changes its configuration - it now is the source's remote control. So if you have programmed the AV with the learned codes from an Apple TV remote – after pressing the AV button, the remote buttons will automatically configure to the Apple remote key-map as programmed. The volume control remains locked to the Processor/Receiver "AMP" mode however. This ensures that anytime you press these keys, you are controlling the Volume or Mute state of the Processor/Receiver regardless of the device you are controlling (Blu-ray player or Cable box for instance).

Buttons/Functions in the Amp Device Mode

Pressing the AMP button puts the remote into the correct mode for controlling the functions of the Processor/Receiver. This allows you to access the menus, adjust bass/treble, turn Room EQ on or off, cycle through decode modes etc...

HTR-3 Remote

Set-up and Configuration

Unit Placement

X/XR Series Processors and Receivers can be placed almost anywhere in your audio equipment stack. It is good practice to ensure that the equipment location is properly ventilated and to make certain not to block the ventilation slots on this or any other component. We recommend placing it so there is at least one foot of free space above, to the sides, and to the rear. Avoid placing the Processor/Receiver directly over large power amplifiers or any other components that generate a lot of heat. Unless they are made by AudioControl, some amplifiers can get pretty hot and have big power transformers that can induce hum into other audio components.

Speaker Considerations and Placement

Front LCR (Left, Center, Right) Speakers

3D interior rendering of a modern living room with sofa, TV, and speakers (no text or symbols)

To present the most realistic sound stage, all three of the front speakers must be tonally balanced. Ideally, these speakers should be identical models. This ensures that the sound doesn't change as it pans across the screen. Place the speakers at the seated ear level. Whenever possible, the three front speakers should also be placed at the same horizontal level for best imaging.

Wide Presence Speakers

Wide speakers create a cohesive immersive sound stage that mitigates any gaps in panning from the front stage to the side stage. Accordingly, these wide speakers should be placed between the front stage speakers and the side surrounds. Channels 13 & 14 can be configured as Wide speakers.

Side Surround Speakers

The surround speakers provide the reverberant, or ambient, sound effects in a multi-channel theater audio system. These speakers should be placed on the sidewalls approximately 36" above the seated ear height of the listeners. They should be directly to left and right sides of the listening position. If you are using surround speakers, which have a dipole sound pattern, they should be mounted in-line with the main seating position. If the surrounds are direct radiator, they should be just behind the main listening seat.

Rear (Back) Surround Speakers

Place these speakers approximately 36" above the seated ear height of the listeners. Additionally, they should be mounted close together on the rear wall of the theater facing the screen.

Subwoofer(s)

The subwoofer is a large speaker that provides the bottom end "kick" in the system. Depending on the size of your listening space, you may require more than one subwoofer to get the bass volume levels that you desire. Outputs 13 & 14, 15 & 16 (not available on the Concert XR-4) can be configured to drive Front and Rear subs discretely. Make certain you remember to include the size of all spaces that are open to the theater in determining how many subwoofers you need.

Height Speakers

Up to six extra speakers may be used for Dolby Atmos or DTS:X systems. One, two or three pairs of speakers (known as Height 1, Height 2 and Middle Heights) can be used to create a sound field above the listening position, allowing you to be surrounded in an amazing "dome of sound." Dedicated speakers for this application can be mounted in the ceiling, or pointed at the ceiling to give a reflected field. We recommend that you research information directly from Dolby Laboratories, DTS & Auro Technologies about these wonderful systems.

If you are using just one pair of speakers, connect them as Height 1, and locate them approximately half way between the listening position and the display, either ceiling-installed, or reflecting off the ceiling. If you are using Height 1 and Height 2 speakers, then the Height 1 pair would be located a little forward of the display screen, and Height 2 pair would be just in front of your listening position.

Channels 13-16

These inputs are configurable (not available on the Concert XR-4). Here is a list of the optional output configurations:

Channels 13 & 14: Channel 15 & 16:

This is just an overview, so do your research carefully and talk with your dealer.

Connection Tips

• Turn off all components before making any connections.
• When making connections, make sure that "left goes to left" and "right goes to right." The obvious and time-honored way to assure this is to assign RED plugs to Right and WHITE/GREY/BLACK plugs to the left. Yellow is usually used for video cables or digital audio connections.
• Wherever possible, keep power cords away from signal cables (inputs from media players, cable box) to prevent induced hum. Bundle all power cords down one side of your equipment cabinet and all the signal cables down the other.
• If you need to run a long cable to the projector or TV, save yourself and your customer the hassle and use a fiber solution for stable HDMI transport.
• Use high quality interconnect cables. We're not going to get into the debate about whether \$100 per meter interconnects improve the sound and picture quality of your system. We do know from experience however that really, REALLY cheap connections can cause problems.

Power Wiring

Like many of today's intelligent home electronics, the Processor/Receiver should be plugged into an unswitched AC outlet so that it always has power. This allows the RS232 and remote control features to work even when the Processor/Receiver is in standby. We always recommend the use of a high quality surge protection device to keep all of your electronics safe from the evils of spikes on power systems.

Audio Connections

The Processor/Receiver has 6 line-level analog audio stereo input RCA pairs, labeled STB, AV, GAME, BD, PVR, and CD. The input circuits are all identical, so you can connect any line-level analog audio source to any of these inputs.

There are 4 coaxial digital audio inputs, labeled SAT, BD, PVR, and CD, and 2 optical digital audio inputs, labeled STB and AV.

There are seven HDMI inputs. Some sources may not offer quality (or any) digital audio through the HDMI connection. In these cases, you can also connect the digital audio in addition to HDMI. This will provide the digital audio signal necessary for high-quality digital surround sound.

Video Connections

The Processor/Receiver is equipped with seven discrete HDMI inputs labeled STB, GAME, AV, SAT, BD, UHD, and PVR. There are two Zone 1 HDMI outputs and one Zone 2 HDMI output that is independent of the Main and Alt HDMI outputs (Zone 2 not available on the XR-4).

Main Output - Connect this to the primary display device located in your main theater. This output is eARC enabled and includes CEC functions which can be turned on and off via the HDMI menu.

Alt Output - Connect this to your secondary display device.

Zone 2 - Connect this to your display and system used in the second zone (Zone 2 not available on the XR-4).

eARC (Audio Return Channel)

The Main Output is compatible with HDMI Enhanced Audio Return Channel (eARC). If you have a supported television then sound from the television's internal streaming services or connected sources will be available using the Processor/Receiver's 'Display' input.

IR (Infrared) Remote Control Connections

The Processor/Receiver has two rear-panel Infrared (IR) inputs to allow for maximum control flexibility with standard IR remote controls. This allows you to place an external infrared receiver where it can "see" the signal from the remote control when the main equipment may be hidden. The IR connections are designed for "modulated" signals and wired for stereo or mono 3.5 mm jacks with "Tip" being the modulated signal and "Sleeve" being ground.

Zone 1 IR - This is ideal to use when the front panel of the Processor/Receiver is hidden away in some dark closet or equipment rack. To prevent the possibility of receiving multiple commands, when you connect an IR receiver to this input, it will disable the front panel IR receiver.

Zone 2 IR - Allows for control of source and volume functions of Zone 2 (Zone 2 not available on the XR-4).

12V Trigger Connections

The Processor/Receiver has two rear-panel 12 volt trigger outputs that can be used to trigger such things as external power amplifier turn-on, projector power on, and screen automation. Each external device must have 12 volt triggering capability for this to work. The jacks are 3.5 mm mono with "Tip" being the 12 volt trigger output and "Sleeve" being ground. Each jack is capable of outputting a 12 volt, 70 mA switching signal. This not to be used for any other purpose such as jump starting the old car on a frosty morning.

Setup Menus

This section of the manual discusses how to navigate the set-up menus of the Processor/Receiver. X/XR Series Processors and Receivers are incredibly flexible and sophisticated and can be “personalized” for use with your performance theater system. While the set-up menus incorporate a number of default settings that we determined will work well with many theater systems, you will want to take the time to go through each of these set-up screens and make the appropriate adjustments to the settings.

To get started in your set up, you can work directly from the front panel of the unit using the front panel buttons or the HTR-3 remote, or you can navigate to the set up options through a web browser by going to its IP address/setup [http://your IP address/setup/]. The web page menus follow the same format as the front panel menus noted below.

Front panel display: Main Menu

Navigating

Navigating the Set-Up Menus is a very simple process that can be done using the appropriate front panel controls on Processor/Receiver or by using the remote control.

1. Press the Menu button once to enter the Setup Menus on the front panel. The main menu will show, from there you can select the parameters for configuration.
2. Use the Input selection button "▲ Input +" and "▼ Input -" to navigate among the menus and use the "◀ Info" and "Mode ▶" buttons to select appropriate menu screen.
3. Press the "SELECT" button or "OK" to select the menu options.
4. Press the Menu button anytime to exit the Menu screens and any setting changes will be saved automatically.

Adjustment Highlight - Using your up/down keys on the remote or front panel, navigate this soothing blue bar to various options that you can adjust. This blue bar cursor will skip over items that are information only

Scroll Bars - These show the position of the displayed screen within longer menus. There are more options and information to see

Input Configuration

Each input has individual audio and video settings that can be adjusted specifically for its use.

Input - Identifies the currently selected source. Settings are displayed below.

Name - Specific name/label for this input that will show on the front display and the OSD. The name can be changed, and this is very useful when more than one source unit has similar functions (for example, two Satellite processors could be named SAT1 and SAT2).

Lip Sync - Many video processors and line multipliers cause a slight delay between the sound and the video picture. Highly compressed video signals such as MPEG encoded satellite processors and some DVDs also suffer from this problem. The Lip Sync setting delays the audio a small amount to allow the video image to catch up. If this is an audio only input - like Aux, then LipSync is grayed out.

Mode - Sets the initial audio decode mode for stereo sources on this input.

Last Mode - recalls the last used setting for stereo sources. See section "Surround Modes" on page 29 for more information.

MCH. Mode - Sets the initial audio decode mode for multi-channel digital sources on this input.

Last Mode - recalls the last used setting for multi-channel sources. See section "Surround Modes" on page 29 for more information.

Bass and Treble - Changes the bass and treble response for all speakers when using this input. Very useful when you have a source unit that has reduced frequency response due to the format (i.e. older VCRs or 8-Tracks)

Room EQ - When the Dirac Live application is run and EQ filters are Downloaded into one of the three slots available, this can be selected.

Not Calculated - (Information only) There are no EQ filters, so cannot be selected.

Project Name - Dirac Live Room EQ is applied to the current source and will display the name of the project from the Dirac Live application.

Off- Dirac Live Room EQ is not applied to the current source.

Input Trim - Selects the maximum analog signal for this input before clipping. This setting should match the audio output of your source units with the available settings being 1, 2, and 4 volts RMS and the default being 2 volts. Source units with low output levels can benefit from being set to higher output settings such as 1 V or 2 V.

Dolby Audio Processing - Applies Dolby Audio Processing to the incoming audio.

Off (default) - Dolby Audio Processing is not applied to this input.

Movie - Suitable for movie viewing.

Music - Suitable for music listening.

Night - Compresses the audio to be more suitable for latenight viewing or listening.

Stereo Mode - If you are using an external subwoofer, and are listening to stereo (two channel) sources, either digital or analog, you can select to configure how the subwoofer receives its bass information.

As Speaker Types - Your normal speaker configuration (as selected in the Speaker Types menu) determines your subwoofer output.

Left/Right - Full frequency audio will be sent to your front left and right speakers with no information going to the subwoofer.

Left/Right+Sub - Full frequency audio will be sent to your front left and right speakers plus bass information is directed to your subwoofer effectively duplicating the lower frequencies.

Sat+Sub - This setting will drive the frequencies defined in your Speaker Types crossover selections to the Sat for higher frequencies and 'Sub' for the lower frequencies.

Note: Stereo Mode is not available when using an analog source and you have selected the Stereo Direct mode.

Sub Stereo - If you have selected the "Left/Right+Sub" or "Sat+Sub" setting in the Stereo Mode menu, then this setting adjusts the level of the subwoofer when you are using a two-channel source.

IMAX Mode - Specifies if IMAX mode is enabled on the incoming audio stream (AUTO) or if forced to ON or OFF.

Auro-matic 3D - Specifies the mode of the Auro-matic 3D upconverter.

Auro-matic 3D Stength - Adjusts the amount of unprocessed to processed signal when using the Auro-Matic 3D upmixer.

Audio Source - Allows you to select how the Processor/Receiver receives audio signals for this source. Settings options are "HDMI," "Digital," or "Analog."

CD Direct - Use with PCM audio - this selection bypasses the compressed audio detection.

General Setup

General information and system controls.

Source Input - (Information only) Displays the currently active audio source input.

Incoming Format - (Information only) Displays format of digital audio stream if present.

Incoming Sample Rate - (Information only) Displays incoming sample rate of digital audio stream, if present.

Incoming Bitrate - (Information only) Displays bit rate of digital audio stream, if present.

Dialnorm - (Information only) When a Dolby Digital audio stream is connected to this input this is the Dialogue Normalization setting requested.

Incoming Video Format - Displays the incoming video resolution.

Audio Compression - Compressing the dynamic bandwidth of the audio can be a good thing, especially for those late night action movie festivals. Compression increases the volume of quiet sections and reduces the volume of the louder sounds. These 3 options for this setting only apply to some Dolby Digital or DTS soundtrack formats that support this function.

Off - (default) Audio compression is not applied (default)

Medium - For loud segments of the audio stream, compression is applied to reduce the level. Dolby True HD content will be compressed automatically

High - Maximum compression is applied with this setting. The differences between quiet passages and loud portions of the audio track are minimized

Balance - Adjusts the left/right balance of the front outputs.

DTS Dialog Control - Sets the level the for dialog channel in DTS audio streams.

Maximum Volume - Limits the highest volume that will play in the main zone. This is useful if you have speakers, amplifiers, or neighbors, with limited power handling abilities.

Max On Volume - This is the highest volume that the unit will play when it is first switched on. This prevents the unit from being turned on at shocking volume levels from the last time you were watching a good movie.

Display On Time - This sets the amount of time the display is lit after a command has been initiated. The default is always on.

Control - Enables or disables RS232 or IP (NET) control, a system that allows control from various third-party home automation systems. Note, only RS232 or IP control can be used, not both. Default setting is IP. The front panel and IR control are always active.

Power On - Determines how the Processor/Receiver powers on.

Standby - the unit is in Standby when powered on.

On - the unit is on and ready when powered on.

Last State - (default) the unit returns to the last On or Standby state before power was lost or the Main power switch was turned to off.

Language - The Front Display Setup Menu and OSD language can be selected from English, German, French, Spanish, Dutch, Russian, and Chinese.

Speaker Types

This series of menus allows you to select the types of speakers that you will be connecting to the Processor/Receiver.

"Large" speaker is one that is capable of reproducing a full range (20-20 kHz) audio signal. Use this setting when not using a subwoofer.

"Small" speaker is one that is not designed to reproduce deep bass frequencies and is generally used with a subwoofer (i.e. Satellite speakers typically can't play below 80 Hz). Please note that you can set High Pass crossovers independently for each speaker type when using the Small setting. For example, if you have your fronts set to Small 50 Hz and your sides and rear set to Small 80 Hz, frequencies below 50 Hz from the front channels as well as 80 Hz and below from the sides and rears will be sent to the subwoofer.

"Height 1, 2" selects the speaker types used for Dolby Atmos and DTS:X.

"None" If you do not have a speaker connected to an output (i.e. No Subwoofer or Back Speakers) then set that speaker size to "None".

"Subwoofer" Selects whether a subwoofer is present in your system.

"Channel 13 & 14" Selects whether Front subs or Wide speakers are present, options include Large, Small at various crossover frequencies.

"Channel 15 & 16" Selects between Rear Subs, Middle Heights or Center Height or none are present.

Height Type - Sets whether Dolby Enabled or ceiling mounted.

Using Channels 6 + 7 for - If your main speaker system has no Surround Back speakers, you can use the power from these unused amplifier channels to power Height 1 speakers, power speakers in Zone 2, or to biamp the front left and right speakers.

Filter slope - Sets the crossover filter slope. Options range from 12 dB to 48 dB

Sub gain - Sets output level trim for all specified subwoofers in 6 dB steps. Range is from 0 dB to -30 dB.

Speaker Distance

graph TD
    A["Front Left"] --> B["Center"]
    C["Surr Left"] --> B
    D["Surr Back Left"] --> B
    E["Surr Back Right"] --> B
    F["Sub Wheeler"] --> B

    I["Sub Wheeler"] --> J["e.g. 4m (12 ft)"]
    K["Surr Right"] --> L["e.g. 2m (6 ft)"]

The Speaker Distance settings help the sound from each speaker arrive at the listening seat at the same time. This provides a much more believable and immersive sound environment. Accurately measure the distance from the center of each speaker to the seated ear position of the main listening seat. Write each of these distances down (select Imperial or Metric) and enter them into the Processor/Receiver using this menu. Speakers not present (as you entered in the Speaker Types menu) will be greyed out. If the Dirac Live application has been used, the speaker distances can still be entered and edited in this menu.

Speaker Levels

It is critical to properly match the levels from each speaker to achieve a correct sound stage. The realism is totally lost if the footprints of a person walking across the screen change in volume as they move from left to center to right. We strongly recommend using a audio analyzer such as the AudioControl SA-4100i for this calibration. The levels are nearly impossible to judge by ear alone. Though not as accurate as using the SA-4100i, you can use a sound level meter for this adjustment.

With the internal test noise generator of the Processor/Receiver, adjust each speaker for a sound pressure level (SPL) of 75 dB using a "slow" response time on the SPL meter, placed at the main listening position at ear height.

You can use an External Test Tone from the currently selected HDMI input if you prefer.

Video Inputs

If desired, you can assign a video source to each of the "audio only" inputs. The default for each of these settings is "None". This is a great way to listen to the ball game over the Internet Radio and watch it over your normal video display device, though timing might be a little off.

HDMI Settings

X/XR Series Processors and Receivers feature very powerful video processing. Video settings should be selected carefully to optimize your video performance.

Zone 1 OSD - This selects the pop-up text messages to be On or Off.

When On, any adjustments made on the unit (like volume, mute state changes, sub trim level) will be shown on your display screen, as well as on the unit's front panel display.

When Off, any adjustments will only be shown in the unit's front panel display. This leaves your screen clear from interruption.

Zone 1 Out - Set the output for Zone 1 from either Output 1 (Main), Output 2 (Alt), or both.

Lipsync (Information Only) - When this feature is supported by the display device, this setting displays how much lip sync is applied to HDMI Outputs.

HDMI Audio to TV - Use this to set audio to be sent to the TV.

HDMI Bypass & IP - Sets the state of IP control and HDMI bypass of the unit while in Standby. When in Low Power mode, network or IP control and HDMI bypass are disabled. With HDMI & IP On, the unit will respond to IP control when in standby and HDMI bypass is enabled.

HDMI Bypass Source - Specifies the source used when HDMI bypass is on. Specific inputs can be specified or the last input used.

CEC Control - Enables/disables CEC control.

eARC Control - Enables/disables automatic volume control from the display.

TV Audio - Enables/disables auto-switching to eARC audio from the display.

Power Off Control - Enables/disables automatic power control from other CEC devices.

Zone Settings

This menu allows you select the audio and video control and volume settings for Zone 2.

Zone 2 Input - Selects the analog audio and video to be used for Zone 2.

Zone 2 Status - Selects if Zone 2 is in Standby or On.

Zone 2 Volume - Displays current volume level in Zone 2.

Zone 2 Max Vol - Selects the maximum volume setting for Zone 2.

Zone 2 Fixed Vol - Allows Zone 2 volume to be fixed at the current volume level. Volume can then be controlled with an external amplifier.

Zone 2 Max On Vol - Selects the maximum volume level for Zone 2 when the Processor/Receiver is powered on or comes out of stand-by mode.

Decoding Modes

Network Settings

The Processor/Receiver has the ability of playing Internet radio stations as well as music stored on a network storage device like a PC or USB flash drive. Its default connection is wired and is set for DHCP - to automatically pick up an IP address if there is a DHCP server on the network.

The Dirac Live room correction system requires the Processor/Receiver to be connected to your network and with control set to IP.

Typically the computer network may use DHCP to automatically make the necessary network settings although the Processor/Receiver can also be configured manually when using a static IP address.

To set up a static IP or other manual entry IP address details, you will need to navigate to the unit's IP address (go to Menu>Network to find it) then type that IP address into a browser, then click on Network Settings for manual configuration.

SSID (Information Only) - Shows the network connection type

IP Address (Information Only) - Shows the unit's IP address

MAC Address (Information Only) - Displays the unique network card address of the Processor/Receiver

Friendly Name (Information Only) - Shows the name you've assigned to the Processor/Receiver

Bluetooth Settings

In this menu, Bluetooth pairing and device management are done.

Pair Device - Makes the Processor/Receiver discoverable by Bluetooth devices

Clear Paired Device List - This will clear the paired devices in the Processor/Receiver

Paired Devices - Paired devices are noted in this list

Playing Audio Files via Network Audio or USB

The network audio client on the Processor/Receiver is capable of supporting the following file formats:

-MP3
– WMA (Windows Media Audio)
- WAV
- FLAC (Free Lossless Audio CODEC)
- MPEG-4 AAC (iTunes with DRM10 support)

Navigate to the Processor/Receiver web page from your computer and select Web Client. From here you can select your USB as a source and control playback functions.

Playing music streaming services natively

Navigate to the Web Client to engage with streaming services directly. Open a browser and type in Processor/Receiver IP address/webclient. From this web client interface, you can set up your music streaming service, like Tidal or Qobuz, and select albums, artists and songs that the streaming service has made available.

Streaming

X/XR Series Processors and Receivers are Roon Ready, Airplay 2, and Google Chromecast built-in enabled. Being Roon Ready means that X/XR Series Processors and Receivers transparently discover and connect to Roon without any configuration, and bit-perfect audio is delivered from Roon to Processor/Receiver. With Airplay 2, you can stream to the Processor/Receiver via AirPlay2 from your favorite music app. Just tap on the AirPlay icon on your device and select the Processor/Receiver. For Chromecast streaming, first download Google Home from the Play store and set up the Processor/Receiver by following through the prompts. Once the Processor/Receiver is set up, you can stream directly to it from your favorite music streaming app. The Processor/Receiver will automatically switch over to the NET input when it receives a music stream.

Bluetooth

To stream from a Bluetooth source, such as your phone, pair your device to the Processor/Receiver via the web page or by selecting BT as the input from the front panel menu. Once paired and the Processor/Receiver is set to BT input, play back your favorite tracks.

Automation Integration

Please Note -

Automation documentation, modules and other control docs are available from the product pages on our website: audiocontrol.com

Part of the joy of a great home theater is that you don't have a tray of remote controls staring at you whenever you want to watch a movie. Hidden away behind the scenes is a workhorse that takes care of the mundane tasks of turning on all the components, lowering the curtains, dimming the lights, popping the corn, etc. This faithful servant can take the form of a simple learning remote control, or a system as capable as a whole house automation system with touch screens. There are a wide variety of theater controllers available.

There are 2 methods of controlling the Processor/Receiver, other than through the IR remote and the Front Panel. You may choose either RS232 or IP control via the General Settings menu. Both methods use the same command structure format as defined in the automation documentation found on our website. The command set also takes advantage of the extensive discrete IR command library with the IR simulation command. This adds a great deal of flexibility to system design, general functionality and personal customization. It is possible to use both hand held remotes and control panels in the same installation depending on your needs.

IP Control

Obtain the IP address from the Processor/Receiver's Network menu. Setting the IP address of the unit to static is good practice. When setting to a static address, always include the DNS and subnet info otherwise your Internet Radio will not likely work. Communication occurs on port 50,000 in the automation system. You will need to confirm that control is set to IP – this is set at the bottom of the General Settings menu.

Example: 192.168.20.246:50000

RS232 Serial Control

You must set the external RS232 control system serial port of your control system to match the data communication speed and format of the Processor/Receiver. If these settings are incorrect, the Processor/Receiver will not respond to the commands.

Communication parameters:

Baud Rate: 38,400

Start Bit: 1

Data Bits: 8

Stop Bit: 1

Parity: None

Flow Control: None

Cable Wiring

The cable wiring to connect the Processor/Receiver to your control system will depend on the RS232 output connection on the controller. Make certain that you wire the Transmit Data output on the serial controller to the Receive Data on the Processor/Receiver and vice versa on the Receive Data line on the controller system. Connect the signal grounds on the control system and the Processor/Receiver series together. The RS232 connection on the Processor/Receiver is a DB-9 Male connector, labeled Control and is wired as follows:

Pin 2 Receive Data (RXD)

Pin 3 Transmit Data (TXD)

Pin 5 Ground

To connect the Processor/Receiver to a standard PC serial COM port; wire the cable in a 'null modem' arrangement using the appropriate serial cable.

    A -->|Receive Data Transmit Data Ground| B

Command Structure - Issuing

The RS232 serial control structure of the Processor/Receiver is a string of hexadecimal values with a minimum of six bytes. When issuing a command, the structure of the string is as follows: Start Transmission, Zone Number, Command Code, Data Length, Data and End Transmission. We will use an abbreviated form for easy reference in the following format:

Parameter

Command

Description

START 0x21 Begin transmission

ZONE NUMBER 0x01 Zone 1

0x02 Zone 2

COMMAND CODE See code list The code of the

command

DATA LENGTH 0x01, 0x02 etc... Number of data parameters to follow

DATA

See code index

The parameters for the

command

ETR

0x0D

End transmission

As an example:

To change the video source (only video, not audio) in Zone 1 to SAT:

0x21 0x01 0x0A 0x01 0x01 0x0D

To change the source (both audio and video), the command is the 0x08 – IR simulation command. See page 36 for more info.

Command Structure - Receiving

Command processing begins when the first 0x0D (carriage return) is received. The Processor/Receiver will respond, either by making the change specified with a status update answer code or by replying with an error answer code, within 3 seconds. More commands, however, may be sent before the Processor/Receiver responds to the first command. When a command is received, the Processor/Receiver echoes the command back in the following format:

Parameter Command Description

START

0x21

Begin transmission

ZONE NUMBER 0x01 Zone 1

0x02 Zone 2

COMMAND CODE See code list The code of the command

ANSWER CODE	0x00	No problems – statusupdated
	0x82	Incorrect	Zone
	0x83	Incorrect	Command
	0x84	Incorrect Parameter
	0x85	Invalid Command incurrent state

0x86 Data length is incorrect

DATA LENGTH 0x01, 0x02 etc... Number of data units to follow

DATA See code list The parameters for the response, limited to 255

ETR 0x0D End transmission

As an example:

Answer code for source change in Zone 1 to DVD: 0x21 0x01 0x0A 0x00 0x01 0x00 0x0D

Simulating the RC-5 IR command via RS232

A key feature in the Processor/Receiver is the ability to simulate RC5 format IR commands via serial commands. The IR simulation command will contain 7 bytes as there will be 2 bytes for the RC-5 command. The actual command is 0x08 with the 2 bytes being the IR command values. The 2 data bytes are the system code then the command code, both these codes are in decimal format. Depending on your software or remote control device, a conversion of these codes to the appropriate format may be needed.

Changes in state from different inputs

While the Processor/Receiver is controlled by a serial command, its state may be changed by other inputs such as the front panel or through IR. Such changes in state will yield a response with an answer code from the Processor/Receiver. In order to determine the command code, you may use the response to get the code for the desired function if you can't find the listing for it in the automation table.

Serial and IR Code Tables

Please head on over to our web site, www.audiocontrol.com, to get the serial/IP protocol doc. You can find a complete listing of the automation protocol – commands, cheats, rich detail that makes most eyes glaze over – at the product pages. You can also find control modules/drivers/profiles on the products pages as well. Alternatively, if you can't sleep, and are unfamiliar with hex, read the doc – it'll put you right to sleep.

Dirac Live speaker setup system

For a more detailed Dirac Live setup walkthrough visit: audiocontrol.com/ dirac-setup/

...or scan:

X/XR Series Processor and Receivers have an automatic speaker setup system called Dirac Live with Dirac Live Bass Control, from Dirac Research. The supplied microphone is used with your computer on the same network to measure the sound output of the system. Dirac Live automatically calibrates the settings of all the speakers in the system, and will apply the optimized EQ settings to the main room. From the measurements, Dirac Live computes the distance, level, and identifies any problems that can be corrected or reduced by room EQ settings.

The procedure for running all this wonderful technology, is as follows:

1. Connect the supplied microphone to the USB port on your PC or MAC connected to the same network as the Processor/Receiver.
2. Position the microphone so it is close to the normal/usual position of your head when you are sitting in your home theater. We suggest using a mic stand (a boom stand works best) to position mic. Point the microphone upwards and in a position where it has a direct line of sight view of all speakers.
3. If your system uses an active subwoofer, set the output level controls to approximately match the front speakers.
4. Run the Dirac Live application on your computer. A calibration test tone will run through all speakers in your system, a number of times as the different speaker responses are calculated. If some speakers are not used, there will be a silence when these are reached. Check the software application for the progress and information.

By default, Room EQ is not automatically applied to the source inputs. You can enable this using the Input Configuration display menu of the unit. Listen to the different sources and source material, and judge if the room EQ settings give an improvement.

During the measurements, try your best to create as quiet an environment as possible. This is not the time for little Timmy's circus animal birthday party.

While EQ settings can be beneficial, there is no substitute for getting things right in the first place, with regard to speaker placement, speaker type, and room treatments to avoid reflections etc.

Troubleshooting Common Problems

General

There are no lights on the Processor/Receiver

√ Pressing any button on the front panel should wake the Processor/Receiver.

√ Verify that the power cord is plugged into a live AC outlet.

√ Verify that the front panel Power switch is "On".

The main front panel display is blank

√ Press the Display button. This button controls the display brightness and also allows you to turn the display off entirely.

The main zone changes while selecting sources from Zone 2

√ Change the Zone 1 Control option in the Zone 2 Configuration Menu to Off.

Video

No video/picture

√ Verify your video display or projector is turned on and set to the correct input for the Processor/Receiver. Press the Menu button on the Processor/Receiver and look for the Setup Menus to show on the video display.
√ Verify the correct input on the video display is selected for the output of the source.
√ Verify the Video Input assignment configurations. Make certain that the correct video input is assigned to the source you are playing.

No Video on Zone 2

√ Verify the HDMI input from the source is connected.

There is no On-Screen Display (OSD)

√ Verify the OSD is turned on in the Processor/Receiver configuration settings.

√ Verify that the correct input is selected on the video display or projector.

Audio

The audio doesn't match the video

√ The Video and Audio input can be selected independently in the Main Menu. Verify they are set the same.

√ Verify the correct Video Input and Digital Audio input assignments are configured for the Source Input.

The sound is poor or distorted

√ Verify the speaker settings configuration matches your speakers. If a speaker is set to Large and it cannot reproduce full range bass, you will hear distortion.

√ If the trouble is only on some channels: Verify the audio RCA cables to the power amplifiers are working and seated properly.

√ If the trouble is in all channels: Verify the Input Trim setting in the Advanced Configurations is not set too low.

Cannot select Dolby Digital or DTS decoding mode

√ The Processor/Receiver can only decode formats encoded onto the source. Normally these are marked on the packaging or liner notes of the material.

√ Verify that the correct format is selected in the Start Menu of the disc.

√ Verify that the digital input from the source is properly connected to the Processor/Receiver.

√ Verify that the digital output of the source is enabled. Some Blu-ray players have a setup menu that can only be accessed if there is no disc in the player.

Hum on analog inputs

√ Verify that all the two channel analog audio cables are connected properly.
√ If the hum only occurs on one source, try a different set of connecting cables.
√ If the hum occurs on a source with an external connection such as an antenna or cable TV, try disconnecting that input. If the hum disappears, put a ground isolator on that connection.
√ It does not know the words.

No audio on Zone 2

√ Zone 2 is muted when unit is first turned on.
√ Make sure you are using a source with analog outputs.

No Zone 2 audio when playing a DTS encoded video

√ Most Blu-ray players cannot output a stereo analog version of the soundtrack while playing a DTS encoded disk. If you want to watch the movie in the second zone, select the Dolby Digital soundtrack on the disk.

My boomerang won't come back

√ It's a stick.

Should your Processor/Receiver Need Service

Before returning any item to AudioControl, you must obtain a return authorization.

Tech Support contact and hours:

[e-mail]

Monday - Friday 8 am -5 pm PDT

After obtaining a return authorization, please write your RA number on the outside of the shipping box and include the following items when returning the unit:

1. A copy of your proof of purchase. No originals please. We cannot guarantee returning them to you.
2. A brief explanation of the trouble you are having with the unit. (You'd be surprised how many people forget this.) If you can supply a really detailed description of the problem, this would be so much better, and our service technicians may add you to their Christmas Card list. Please include any notes about the system and other components you are using. Is it an intermittent problem that only occurs on the first full moon of Spring?
3. A return street address. (No PO Boxes, please).
4. A daytime phone number in case our technicians have a question about the problem you are having, or if they are just feeling lonely.

Package the unit in the original packaging if you still have it, and if the cat hasn't had three litters of kittens in the box. Use great care and plenty of good packing materials to protect the unit and prevent it from moving about inside the box. Do not use loose materials like packing peanuts or real peanuts.

You are responsible for the freight charges to us, but we'll pay the return freight back as long as the unit is under warranty. We match whatever shipping method you use to send it to us, so if you return the unit overnight freight, we send it back overnight. We recommend United Parcel Service (UPS) for most shipments.

Warranty

...and now a word from the legal department...

People are scared of warranties. Lots of fine print. Months of waiting around. Well, fear no more. This warranty is designed to make you rave about us to your friends. It's a warranty that looks out for you and helps you resist the temptation to have your friend, who's "good with electronics", try to repair your AudioControl product. So go ahead, read this warranty, then take a few days to enjoy your new X/XR Series Processor/Receiver before logging onto the our web site at www.audiocontrol.com to register your purchases.

Our warranty has conditional conditions! "Conditional" doesn't mean anything ominous. The Federal Trade Commission tells all manufacturers to use the term to indicate that certain conditions have to be met before they'll honor the warranty. If you meet all of these conditions, we will warrant all materials and workmanship on the Processor/Receiver for five (5) years from the date you bought it, and we will fix or replace it, at our option, during that time. Here are the conditional conditions:

1. You need to register your purchases with us by going to the AudioControl product registration page at www.audiocontrol.com/product-registration.
2. You must keep your sales receipt for proof of purchase showing when and from whom the unit was bought. We're not the only ones who require this, so it's a good habit to get into with any major purchase.
3. The Processor/Receiver must have originally been purchased from an authorized AudioControl dealer. You do not have to be the original owner, but you do need a copy of the original sales receipt or invoice.
4. You cannot let anybody who isn't: (A) the AudioControl factory; (B) somebody authorized in writing by AudioControl to service the Processor/Receiver. If anyone other than (A) or (B) messes with the Processor/Receiver, that voids your warranty.
5. The warranty is also void if the serial number is altered or removed, or if the Processor/Receiver has been used improperly. Now that sounds like a big loophole, but here is all we mean by it:

Unwarranted abuse is: (A) physical damage (don't use the Processor/Receiver to level your projection TV); (B) improper connections (120 volts into the RCA jacks can fry the poor thing); (C) sadistic things. This is the best product we know how to build, but if you strap it to the front bumper of your Range Rover, something will break.

Assuming you conform to 1 through 5 (and it really isn't all that hard to do) we get the option of fixing your original unit or replacing it with a new one.

Legalese Section

This is the only warranty given by AudioControl. This warranty gives you specific legal rights, and you may also have rights that vary from state to state. Promises of how well the unit will work are not implied by this warranty. Other than what we've said we'll do in this warranty, we have no obligation, express or implied. We make no warranty of merchantability or fitness for any particular purpose. Also neither we nor anyone else who has been involved in the development or manufacture of the unit will have any liability of any incidental, consequential, special or punitive damages, including but not limited to any lost profits or damage to other parts of your system by hooking up to the unit (whether the claim is one for breach of warranty, negligence of other tort, or any other kind of claim). Some states do not allow limitations of consequential damages. Failure to register your product negates any service claims. The warranty included with the unit shall supersede this plain-text version if there is any inconsistency between the two.

Appendix A: Feet Removal Procedure

Note: If this was your real appendix, please consult your health care professional as it should not look like this.

The feet of the unit can be removed to create a cleaner look when fitting the unit into a rack.

You must make sure that the ventilation slots in the bottom panel are not covered and that cooling air flow is not restricted.

Tools Required

- A medium-sized flat-bladed screwdriver, 1/4" wide or narrower.

- Needle-nosed pliers

The Procedure

1. Make sure that the power cord and all other cords are disconnected from the unit.

2. Carefully place the unit upside-down on a flat surface, such as the kitchen table with a clean and dry towel on it.

3. Remove the adhesive non-slip grips from the bottom of each foot.

Two black mechanical components: a circular washer and a circular impeller with cutouts (no text or symbols visible)

1. Identify the four locking tabs securing the foot to the chassis. The photo of a removed foot shows the details of the locking tabs.

1. Use the small flat-bladed screwdriver to gently pry the four locking tabs outward to release the foot from the chassis. Use the needle-nose pliers to pull upward at the same time, with (to get all technical for a moment) a bit of a jiggle-joggle motion.

2. Repeat for all 4 feet. Place all the feet in your sock drawer in case you wish to reinstall them in the future.
