Where to put it
The MX100 can be placed upright on a table or shelf, standing on its four feet. It also can be custom installed in a piece of furniture or cabinet. The four feet may be removed for custom installations. The four feet together with the mounting screws should be retained for possible future use. Do not use
different size screws when re-installing the feet. With the feet removed, the MX100 requires a ventilation cutout. Dimensions for the panel cutout and bottom ventilation cutout are shown in "Figure 02- Custom cutout dimensions" on page 7.
Always provide adequate ventilation for your MX100. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the MX100 directly above a heat generating component such as a high-powered amplifier. If all the components are installed in a single cabinet, a quiet running ventilation fan can be a definite asset in




Figure 01- MX100 Dimensions
maintaining all the system components at the coolest possible operating temperature.
A custom cabinet installation should provide the following minimum spacing dimensions for cool operation:
• 2 inches (5.1cm) above the top
• 2 inches (5.1cm) below the bottom
- 1 inch (2.5cm) on each side of the MX100 so that airflow is not obstructed
• 20 inches (50.8cm) depth behind the front panel
- 1-7/16 inch (3.7cm) in front of the mounting panel for knob clearance
Be sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing. See Figure 02 on page 7.
Making the Cuts
Here are the dimensions for the cutouts needed for custom installation. A ventilation opening is essential for any installation with the four feet removed.

Figure 02 Custom cutout dimensions
Rack Mounting
To rack mount the MX100, the two included Side Rack Mount Brackets should be installed. Follow these instructions for each side:
- Remove the two screws from the front side of the MX100's side panel

- Secure the Side Rack Mounting Bracket to the MX100 using the larger supplied screws. Do not re-use the previously removed screws. Use the smaller supplied screws to secure the bracket to the Front Panel.

Making Connections
10baseT LAN
Use an Ethernet cable to connect the MX100 to a network router. The network connector is located on the top rear of the MX100 to the left of the CAUTION label. It is labeled NET.
By default, the MX100 has DHCP set to ON and will automatically receive an IP address from the router. This setting can be changed.
HDMI
The MX100 has 4 HDMI Inputs. A high-performance HDMI cable is recommended to take advantage of the 18 Gbps speed capabilities of all 5 HDMI ports. The HDMI cables should support 4K@60Hz, and YCbCr 4:2:2 (4:4:4/RGB) as well as Ethernet and ARC. Cables designed for HDMI 2.0 are fine. Though HDMI is backward compatible, older cables may have issues with the higher bandwidth.
Use HDMI OUT/eARC when connecting to an ARC (Audio Return Channel) enabled television (or any HDMI capable TV).
ARC can provide two-way communication between units allowing for volume control and lip-syncing functions to ensure audio and video are perfectly matched. This allows for more intelligent operation between components as well as less cable clutter. Make sure the ARC is enabled in your TV's setup menu.
The MX100 supports eARC. eARC allows for even higher bandwidth and will allow for higher quality audio including uncompressed 7.1 surround, Dolby Atmos and DTS:X.
USB
There is a type-A port on the rear of the MX100 which is labeled USB 5V/1A. The USB port is used for firmware upgrades and to save and restore MX100 setup information. The USB port IS NOT for general USB use or charging devices.
Microphone
The SETUP MIC Input is for connecting the supplied MX100 Microphone using the microphone's attached cable and an 1/8 inch connector. The microphone is used in the Audyssey® calibration for tuning the system to your room. For instructions see "Audyssey®" on page 24.

7 Channel Power Amplifier (You may have separate amplifiers)
RS232
The RS232 jack is used to connect the MX100 to automation controller devices with RS232 connectors. To utilize this feature, you will need an appropriate RS232 Data Cable. The RS232 Data Cable should be an 1/8 inch (3.5mm) stereo mini phone plug to a subminiature DB9 connector.

Figure 08—Mini plug for RS232 connection

Figure 09- DB9 connector pin layout

- N/C (no connection) 6. N/C
- Data In (RXD) 7. N/C
- Data Out (TXD) 8. N/C
- N/C 9. N/C
- Gnd
Typical RS232 settings are:
- 8 data bits, no parity and one stop bit
- Baud rate fixed at 115,200 bits per second
Wired IR Inputs
The IR Input allows an external IR receiver to be attached to the MX100. The Input is labeled IR IN. By attaching an IR receiver using a 3.5mm cable (see Figure 10), the MX100's Remote Control can be used in another location without a line-of-sight to
the MX100's front IR sensor.

Figure 10 IR 3.5mm connector
The IR Input is configured for non-McIntosh IR sensors such as a Xantech Model DL85K Kit. If using an external IR receiver for the MAIN ZONE in the same room as the MX100, you may wish to disable the front IR sensor, which also controls the MAIN ZONE. This will avoid potential timing issues of receiving the Remote Control's commands from two different Inputs. The front IR can be turned on/off in the GENERAL section of the SETUP MENU.
Setup>GENERAL>RCLock
To use the front panel to disable or enable the IR sensor (easier using Setup through a browser):
- Press and hold the LEFT Knob for two seconds to enter the Setup menu
- Rotate the Left Knob until you see GENERAL on the display
- Press and release the Left Knob
- Rotate the Left Knob until you see SETUP: GENERAL RC LOCK on the display
- Press and release the Left Knob
- Rotate the Right Knob to select On or Off
SETUP: RC LOCK ON
Figure 11- Setting the Remote Control Lock
RC LOCK ON will disable the front IR sensor so it will not detect Remote Control input (and possibly cause interference with a wired IR input). To enable the IR sensor to detect a Remote Control's IR data, set RC LOCK to OFF (the default).
Digital Inputs
There are four digital Inputs in the MX100:
- Two Toslink Optical Inputs
- Two Coaxial Digital Audio Inputs
The two Coaxial Inputs are labeled:
• COAX 1
• COAX 2
The two Optical Inputs are labeled:
• OPT 1
• OPT 2
The default names and assignments can be changed in setup.
The Optical Inputs require a Digital Optical Audio Cable Toslink Cable. The Coaxial Inputs use Digital Audio Coaxial Cables with male RCA type connectors.
AC Power
This connection is essential. Plug the female end of the supplied AC Power Cord into the AC connector located in the rear right corner of the MX100. Plug the male end of the AC Power Cord into a grounded and functioning AC outlet.
Balanced Audio Outputs
There are 13 male balanced XLR connections on the back of the MX100 to accommodate a wide variety of speaker configurations. Connect balanced XLR cables to the corresponding powered speakers or amplifiers. Here are the possible connections:
- FR (Front Right)
- FL (Front Left)
• C (Center)
• SR (Surround Right)

• SL (Surround Left)
• SBR (Surround Back Right)
• SBL (Surround Back Left)
• HR1 (Height Right 1)
- HL1 (Height Left 1)
- HR2 (Height Right 2)
- HL2 (Height Left 2)
• SW1 (Subwoofer 1)
• SW2 (Subwoofer 2)
HR1 and HL1 should be forward of HR2 and HL2. The MX100 support of Height speakers is limited to Top Front, Top Middle and Top Rear locations.
Setting up speakers for a surround setup takes planning, measuring and installation. Depending on your level of expertise and available time, you may wish to employ the services of your McIntosh dealer for expert setup of your system. Professional installation of in-ceiling speakers is particularly important due to gravity and the location above your head.
The number, types and locations of speakers are key elements in setting up the system. There is a multitude of possible configurations, and the MX100 is very flexible in its setup to adapt to many of these configurations.
Often surround setups are referred to by numbers for example 7.2.4. The first number refers to the number of traditional "floor" speakers (front, center and surround). The second number is the number of subwoofers that can be connected, and the third number refers to the number of in-ceiling or upward firing speakers in the setup.
The type of speaker (size and location) will be entered later during Speaker setup. The distance of the speaker from the listening location is manually entered in the Speaker setup, or automatically
entered during the Audyssey® calibration process. At this stage, the connection from the MX100 to the various amplifiers and powered speakers should be made using quality balanced XLR cables.
Power Control (Trigger) Outputs
The MX100 has two Power Control Outputs or Triggers. Power Control enables power on/off signals to go to connected components so that other components can automatically power on (or off) as called for by the MX100. For example, you may want a DVD player and a certain monitor to power on when HDMI 1 Input is selected, or you may want all components to power off when powering off the MX100. For Setup instructions see Trigger1 and Trigger2 on page 21.
Connect components using a 3.5mm stereo mini plug.

Figure 12- Power Control (trigger) mini plug
Data Out
The MX100 will convert IR Remote Control data to share with McIntosh components connected to the Data Ports. This will allow the operation of primary functions of a source to be operated with the MX100's Remote Control as well as allow units that are out of range of an IR signal to receive commands.
There are two ways to change the settings of the MX100.
- Front Panel Method using the Vacuum Flou
rescent Display (VFD) and Left Knob or
Remote Control
• Using a browser on a connected computer
Each method follows the same menu structure. Most will find it easier to navigate and enter information on a computer. If you don't have a connected computer or the MX100 is not connected to your network, then using the Front Panel method can accomplish almost all the same things using some additional patience.
To use the browser method, you will need the IP address of the MX100. This can be determined using the Front Panel Method. After the example below of determining the MX100's IP Address, the browser method will be used for examples to follow in this manual. The submenus outlined for the browser menus are the same for the Front Panel Menu. Clicking the mouse button and selecting with the Left Knob will traverse the MX100's Setup in the same way. To go back in the Front Panel Method, turn the Left Knob clockwise. The last menu choice is always "Menu Back". Choose Menu Back to go to the previous menu.
In this manual, submenus are denoted in the style:
Setup>SPEAKERS>Floor Layout
which means from the Setup menu choose the SPEAKERS submenu then choose Floor Layout.
Entering Setup
To enter Setup mode using the Vacuum Fluorescent Display (VFD):
- Press and hold the Left Knob for Two seconds and then release
(A short push of the Left Knob will bring up Trim settings. See “The Trim Menu” on page 28.)
Determining the IP Address
Setup>Network>Information>IP Address
- In Setup Mode, turn the Left Knob and scroll to Network
- Select by pushing the left knob
- Scroll to Information and select
- Scroll to IP Address and select
- Note the IP Address
Exiting Setup
To exit Setup, push and hold the Left Knob for two seconds.
To return to a previous menu, scroll down to last menu choice which will be MENU BACK. Select MENU BACK by pushing and releasing the LEFT KNOB. On the top most menu, the last menu choice will be MENU OFF which will exit Setup.
The Setup Menu will time out after 30 seconds of no user input.

Figure 14- Browser Setup Menu
Navigating Setup with the Remote Control

Figure 15- Setup using the Remote Control
Enter the Setup Menu by pressing the Setup button (A). The Setup Button has a blue circle on it. You can scroll through the Setup options by pressing the Up Arrow (B) or Down Arrow (C) on the silver ring.
Push the SELECT button (G) to choose an option to change.
Use the Left Arrow (D) and Right Arrow (E) on the silver ring to change values for the selected Setup option. The new value will be saved automatically.
You may use the Up Arrow (B) or Down Arrow (C) to view another option.
The Mode/Exit button (F) will navigate up a menu level or exit from the top menu just as selecting MENU BACK or MENU OFF will.
The Setup Menu will close after 30 seconds of inactivity.

Setup from a Browser
Setup is easier from a web browser. Open a browser window on a computer connected to the same network as your MX100. Enter the IP address for the MX100 (see "Determining the IP Address" on page 13) in the address bar of your browser.
The Setup Menu (see Figure 16) has seven main submenus.
- Audio
- Video
- Inputs
- Speakers
- Network
- General
- Audyssey
Audio Setup Menu
Setup>Audio
The Audio menu is divided into two main submenus:
- Audio Adjust
- Audyssey
In the Audio Adjust submenu, the following can be adjusted:
- Subwoofer Level Adjust
- Bass Sync
• Audio Delay (Lip Sync) - Volume Scale
• Volume Scale (Linear or dB Level) - Volume Limit
- Surround Mode Music
- Surround Mode Movie
- Surround Mode Game
Subwoofer Level Adjust
Subwoofer Level Adjust allows for adjusting your attached Subwoofer to be adjusted from -12dB to +12dB.
Bass Sync
For contents recorded in multi-channel such as Blu-ray discs, the recorded Low Frequency Effects (LFE) may be out of sync and delayed. This function allows you to correct the delay with an adjustment of 0 ms to 16 ms.
Audio Delay (Lip Sync)
Audio Delay compensates for incorrect timing between video and audio. When Auto Lip Sync is set to On, the timing difference will be automatically corrected with compatible TVs.
The Adjust option allows you to manually adjust the delay correction from the Default of 0 ms up to 500 ms.
Volume Scale
There are two choices for how to display the Volume. The default is a Volume Scale Linear which displays the volume on a scale of 0 (mute) to 99. The second option is Volume Scale dB Level. This will express the volume as decibel (dB) level. The decibel scale is from -103.0dB (mute) to 18dB. Note the displayed dB scale increments are not uniform as they have been designed to give a meaningful level adjustment depending on the actual level being listened to.
Volume Scale Linear/dB Level
You can change the current volume level of the MX100 using the slider. Slide towards the right to increase. (Left will decrease the volume level.) The current volume percentage for the linear scale or dB for the dB scale will appear in the box to the right.
Volume Limit
Volume Limit can protect equipment and/or ears from unintended extreme volume by setting an upper threshold for how high the volume level can be set. Volume Limit can be set to Off (the default) or to one of these three volume limits:
- 60 (-1.5dB)
• 70 (3.5dB)
• 80 (8.5dB)
If Volume Limit is not Off, the MX100's volume level can not be set above the selected Volume Limit.
Surround Mode
In the Surround Mode setup, you can assign a Surround Mode to each of three sound categories:
- Music
- Movie
- Game
These three sound categories can be quickly assigned to an input using the Trim Menu.
Categories make it easier for someone unfamiliar with DTS or Dolby to select the proper Surround Mode by selecting Music, Movie or Game which can be assigned to any of the following choices in Setup:
- AUTO (default)
- Dolby Surround
- DTS Neural:X
• Multi-Channel Stereo - Stereo
Auto
Auto will always send audio to all configured speakers no matter the input audio stream type. It will use Dolby Surround to send audio to all configured speakers if the incoming audio stream is
Dolby encoded. It will use DTS Neural:X to send audio to all configured speakers if a DTS encoded audio stream comes in. If a 2 channel or multi-channel PCM stream comes in, it will use Dolby Surround to send audio to all configured speakers.
Dolby Surround will invoke Dolby's post processor to always send audio to every configured loudspeaker no matter the input stream type.
DTS Neural:X will invoke DTS' post processor to always send audio to every configured loudspeaker no matter the input stream type.
Multi-Channel Stereo will downmix and/or upmix to send audio to all Left and Right floor speakers (plus sub if configured) no matter the input stream type.
Stereo will downmix to send audio to only the Left and Right front speakers (plus sub if configured) no matter the input stream type.
Through will neither upmix or downmix. The input stream will be sent to the configured speakers per the input file stream with no post processing. In the Trim Menu (see "The Trim Menu" on page 28), the current input can be assigned to:
- Music
- Movie
• Game - Auto
- Through
The Surround Mode represented by the Trim selections Music, Movie and Game must be assigned in Setup. If no assignment has been made, the Default for each is Auto.
Audyssey
In the Audio Setup menu, three Audyssey setting can be adjusted:
- MultEQ
- Dynamic Volume
• Dynamic EQ Offset

Figure 16- Audyssey ^3 in Audio Menu
MultEQ XT32 optimizes the frequency response of your speakers. It compensates for both time and frequency characteristics of the listening area based on Audyssey ^® Setup.
MultEQ menu options:
- Reference
- Flat
The default setting is Reference. Reference provides a compensation curve that is optimized for movies with a slight roll off at the higher frequencies. With the volume set for 0dB (63%), you will be hearing the mix at the same level the mixers heard it. The Flat setting is optimized for small rooms where your listening position is closer to the speakers. Keep in mind that many movie soundtracks are optimized for large theaters. The options in the Audyssey® setup section help maintain the theater experience in smaller spaces as well as at lower volumes. The Flat setting utilizes the Audyssey room correction curves without the additional compensations for movie mixing.
Dynamic EQ solves the problem of deteriorating sound quality as volume is decreased by taking into account human perception and room acoustics. Dynamic EQ can be turned On and Off in the Trim Menu (see "The Trim Menu" on page 28). If it is On (the default), the Reference Level Offset option appears. Audyssey ^4 Dynamic EQ ^* is referenced to the standard film mix level. It makes adjustments to maintain the reference response and surround envelopment when the volume is turned down from 0dB. However, film reference level is not always used in music or other non-film content. Dynamic EQ Reference Level Offset provides three offsets from the film level reference (0dB, 10dB, and 15dB) that can be selected when the mix level of the content is not within the standard.

| Offset | Content |
| 0dB (Default) Optimized for movies | |
| 10dB Select this setting for jazz or other music that has a wider dynamic range. This setting should also be selected for TV content as that is usually mixed at 10dB below film reference | |
| 15dB Select this setting for pop/rock music or other program material that is mixed at very high listening levels and has a compressed dynamic range | |
Dynamic Volume
Dynamic Volume solves the problem of large variations in volume level between TV, movies and other content (between quiet passages and loud passages, etc.) by automatically adjusting to the user's preferred volume setting.
The settings available for Dynamic Volume ranging from least to most adjustment are:
• Light
- Medium
- Heavy
Medium is the default set if Dynamic Volume is set to On in the Trim Menu (see “The Trim Menu” on page 28). Dynamic Volume can be turned off using the Trim menu. The setting chosen in setup for Dynamic Volume is utilized for all channels when not turned off. Enabling Dynamic Volume will also enable Dynamic EQ.
Video Setup Menu
Setup>Video
The Video Setup Menu has breaks into two submenus:
- HDMI Setup
- On Screen Display
The HDMI Setup Menu has six submenus:
- Pass Through
• CEC - ARC
• TV Audio Switching - Power Off Control
- Power Saving
The On Screen Display menu has one submenu:
• Volume
Setup>Video>HDMI Setup>Pass Through
Pass Through (written as HDMI PASSTHRU on the front display) allows an HDMI Input to be assigned so that when a signal is received by that HDMI input, while in standby mode, the MX100 will pass the complete signal to the HDMI output exactly as it was received for video and audio playback by a connected TV or monitor.
To avoid unexpected results when using the Pass Through feature, such as your TV powering on your MX100, CEC should be disabled in setup.
| Setting Values | |
| HDMI PASSTHRU OFF | (default) |
| HDMI 1 | |
| HDMI 2 | |
| HDMI 3 | |
| HDMI 4 |
Setup>HDMI Setup>ARC
Use HDMI connection labeled OUT/ARC when connecting to an ARC (Audio Return Channel) enabled television.
ARC can provide two-way communication between units allowing for volume control and lip-syncing functions to ensure audio and video are perfectly matched. This allows for more intelligent operation between components as well as less cable clutter. Make sure the ARC is enabled in your TV's setup menu as well as on the MX100.
| Setting Values | |
| ARC Off | On (default) |
Setup>HDMI Setup>CEC
CEC (Consumer Electronics Control) is an addition to the HDMI standard which allows control signals from one device to communicate with another device via an HDMI cable connection. If you change HDMI Control settings, reset power to connected devices.
Make sure CEC is enabled on all devices you wish to utilize CEC.
| Setting Values | |
| CEC Off | On (default) |
Notes about ARC and CEC
To use ARC, CEC must also be set to On. To use CEC and the additional commands of TV Audio Switching, Power Off Control and Power Saving, CEC must be set to on, so your television and MX100 can better communicate.
The world of ARC and CEC is not yet perfect. It is certainly getting better, but not every component in the world is speaking precisely the same language.
There may be circumstances where you may have better performances by turning these features off. These features can be enabled or disabled at any time on the MX100.
Remember to enable CEC on your television if you want to use CEC with the MX100.
CEC should also be set to Off, if you are using a third-party control system so that CEC does compete with your external controller.
The ARC feature, when enabled, will work with the TV Audio input and a television connected to the HDMI OUT/ARC connection.
TV Audio Switching, Power Off Control and Power Saving are only available options if CEC is turned On.
| Setting Value | |
| TV Audio Switching On | Off (default) |
| Power Off Control All (default)VideoOff | |
| Power Saving On | Off (default) |
TV Audio Switching, when On, will select TV Audio when receiving a command from the TV. Power Off Control, when All, the MX100 will enter Sleep mode when the TV is turned off regardless of input. When Power Off Control is set to Video, the MX100 will enter Sleep mode when the TV is turned off and the MX100's input is set to an HDMI input. Set to Off, the TV's power will not effect the MX100's Standby mode.
Power Saving, when On, will put the MX100 in Sleep mode if the audio source is TV and the TV's audio output is set as the TV's speaker. Power Saving will apply when the MX100 is using an
HDMI input.
On Screen Display, when On, will display the volume on an attached TV when the volume is activated. Off will disable this feature.
| Setting Value | |
| Volu me Off | Bottom (default)Top |
Bottom and Top refer to the position on the TV where the volume will be displayed. Both Bottom and Top enable (on) the On Screen Display feature.
Inputs Setup Menu
Setup>Inputs
The Inputs Menu allows you to customize the name of an input as it will appear on the display. Unused inputs can also be hidden so as not to appear as choices. They can also be easily restored when needed. Note that an Input's name can only be changed through the browser interface.
The Input Adjust section of the Inputs Menu allows you to set a Trim Level for a Source.
| Setting Values | |
| Input HDMI 1 | HDMI 2HDMI 3HDMI 4HDMI TVOPT 1OPT 2COAX 1COAX 2 |
If you are adjusting the setting using the MX100's display, the current Input will be adjusted. The Trim for each Input can be individually set from

Figure 17- Input Adjust
The source Trim level can be adjusted from -12dB to +12dB. The center is 0dB.

Speakers- Setup Menu
The Speakers setup menu is where you tell the MX100 what the rest of the world looks like. The basic speaker structure of your system should be entered in:
- Amp Assign
- Speaker Configuration
- Crossovers
The input of distances of your speakers can be entered manually. Distances will be provided automatically when the Audyssey setup program is run. They can be edited if desired. Audyssey will run through your speaker configuration. Having an accurate accounting of your speaker speeds the Audyssey process by avoiding Audyssey looking for phantom speakers.
In Amp Assign, you select how to use the preamplifier section of the MX100. In the Amp Assign section of Setup, you can tell the MX100 what speaker setup scheme you will be using. This assignment is necessary before running Audyssey MultEQ calibration.
Setup>Speakers>Amp Assign
| Amp Assign | |

Note that choosing some options will eliminate other options.
The Speaker Position table below provides a guide for speaker placement. Speaker Type should remain consistent from MX100 outputs to amplifier connections and the speakers themselves. See “Balanced Audio Outputs” on page 11.
| Speaker Position | |
| Front The Front | Left and Right speakers should be an equal distance from the main listening position. The distance between each speaker and your TV should also be about the same. |
| Center The Middle | Middle speaker should be between the Front speakers and above or below your TV. |
| Top Front Mount | The Top Front Left and Right speakers on the ceiling slightly in front of your main listening position and align with the Left and Right Front speakers. |
| Top Middle Mount | The Top Middle Left and Right speakers directly above the main listening position and align with the Left and Right Front speakers. |
| Top Rear | Mount the Top Rear Left and Right speakers on the ceiling slightly behind your main listening position and align with the Left and Right Front speakers. |
| Subwoofer Place the Subwoofer at a convenient location near the Front speakers. If you have two Subwoofers, place them asymmetrically across the front of your room. | |
| Front Dolby speaker Left/Right | Place the Front Dolby Enabled speakers on the Front speakers (left and right). For a Dolby Atmos Enabled speaker integrated with a Front speaker, place the Dolby Atmos Enabled speaker instead of the Front speaker. |
| Surround Dolby speaker | Place the Surround Dolby Enabled speaker on the Surround speaker. For a Dolby Atmos Enabled speaker integrated with a Surround speaker, place the Dolby Atmos Enabled speaker instead of the Surround speaker. |
| Back Dolby speaker | Place the Back Dolby Enabled speaker on the surround back speaker. For a Dolby Atmos Enabled speaker integrated with a Surround Back speaker, place the Dolby Atmos Enabled speaker instead of the Surround Back speaker. |
Dolby Enabled speakers reflect the sound off the ceiling to allow the sound to come from over your head by using a special upward-pointing speaker that is placed on the floor. See Figure 18.

Speaker Configuration
Setup>Speakers>Speaker Config
Here is where you tell the MX100 what type of speakers are connected. The available speaker categories are based on the settings in Amp Assign (See page 18).
Speakers are defined as Large or Small. A Large Speaker is a full-range speaker. (Technically, a speaker able to reproduce bass frequencies down to 35Hz within -3dB of the midrange frequencies.) If it is not Large, then it is Small.
Set each speaker category to Large or Small. For a system with a Subwoofer(s), choose the number of subwoofers (1 or 2).
| Speaker Options | |
| Front Large / Small | |
| Center Large / Small / None | |
| Subwoofer 1 speaker / 2 speaker / None | |
| Surround Large / Small / None | |
| Surround Back Large / Smalls | |
| Top Front Large / Small | |
| Top Rear | Large / Small |
| Top Middle | Large / Small |
Crossovers
Setup>Speakers>Crossovers
Sound below the crossover frequency is cut off from the Output to "Small" speakers and is outputted to the subwoofer or front speakers.
The default crossover frequency is "80Hz", which will work best with the widest variety of speakers. We recommend setting to a higher frequency when small speakers are used. For example, set to "250Hz" when the frequency range of the speakers is 250Hz to 20kHz.
Sound below the crossover frequency is cut off from the Output to "Small" speakers and is outputted to the subwoofer or front speakers.
You can choose Individual or All. The Individual option will allow each available speaker's crossover frequency to be set individually. The All option will globally set the Crossover Frequency to the chosen value. Available values are:
40 Hz / 60 Hz / 80 Hz / 90 Hz / 100 Hz / 110 Hz / 120 Hz / 150 Hz / 200 Hz / 250 Hz
Bass Type
Setup>Speakers>Bass Type
The Subwoofer Mode can be set for:
- LFE (Low Frequency Effects) which would provide, to the subwoofer(s), the LFE channel plus the low frequency output below the set crossover frequency of speakers set to small (see "Speaker Configuration" on page 19)
- LFE+Main which would include the LFE channel as well as the low frequency output, below the set crossover frequency, of the Main channel

The Bass Low Pass Filter (LPF) sets an upper limit for frequencies that are sent to the Subwoofers when LFE+Main is selected. The options are:
80 Hz / 90 Hz / 100 Hz / 110 Hz / 120 Hz /
150 Hz / 200 Hz / 250 Hz
Frequencies above the chosen option will not be sent to the Subwoofer. The LPF setting does not apply to content sent from the LFE channel to the subwoofers.
Speaker Distances
Setup>Speakers>Distances
In this section, the distances of your speakers from the main listening position should be entered. This will aid in perfecting 3D imaging.
For each speaker listed in the pull-down Distances menu, enter the distance from the main listening position to the speaker in meters.
To convert feet to meters, multiply the number of feet by 0.3048.
The value can be accurate up to a tenth of a meter. The Audyssey program will provide more exacting information. The information entered here provides a baseline to compare the Audyssey findings.
For Dolby Enabled speakers, enter the distance to the speaker. Do not calculate the angled path that the reflected sound will travel. Audyssey will handle this.
Test Tones & Levels
Setup>Speakers>Test Tones & Levels
The Test Tones and Levels submenu provides the ability to manually set relative levels for all speaker types, and may be used to confirm proper wiring. This does not need to be set if using Audyssey calibration.
When Test Tone is set to On, a tone will play through the Speaker type selected in the Levels dropdown box. Using a sound meter or your ears, you can set the relative level from -10dB to +10dB. The default is 0dB.
Audyssey will automatically set levels and will over-write offsets set previously. Likewise, manually setting Test Tones will replace Audyssey settings.
Network Setup Menu
Setup>Network
The Network Setup menu has four sections:
• Network Information
- Network Control
- Friendly Name
• Network Settings
Network Information displays the IP Address and the MAC address of the MX100. For instructions on determining the IP Address using the front panel see "Determining the IP Address" on page 13.
Network Control has two settings: On or Off. The default is Off. When Network Control is enabled (On), a control system such as one using RS232 commands over IP can awaken the MX100 from a sleep state. When Network Control is off, the MX100 will enter standby mode when powered off. The monitoring of network traffic with Network Control On uses slightly more power when the MX100 is in sleep mode.
Friendly Name provides a more individual way of identifying your MX100 on the network with devices that recognize Friendly Names.
The default Friendly Name of "MX100" can be changed by selecting an alternative name from the Preset Name dropdown list. To create your own
name for the MX100, choose "Custom" from the Preset Name dropdown box and then type the new name in the Friendly Name box. Custom names can only be entered from the Browser interface. Preset names can be chosen using the front panel interface.
Network Settings allows you manually entering network information. You may do this if you want to have a static IP Address for the MX100. The default is for DIICP is On. With DIICP on, all the network information will be assigned automatically from your router.
To manually enter Network Settings, select "Off" for DHCP. This will allow you to enter settings for:
- IP address
- Gateway (typically the IP address of your router)
- Subnet Mask (Typically 255.255.255.0)
• DNS address (typically the IP address of your router)
When you have completed making Network Settings changes, select the "Apply All Settings" button to save your changes.
General Setup Menu
Setup>General
The General Menu has Six submenus:
- Firmware Info
- Save and Load
- Trigger1
- Trigger2
- RCLock
- Auto Off
Factory Reset
Factory reset and the ability to save configurations are part of the General Setup Menu.
Firmware Info displays the installed version of the MX100's firmware. Firmware is software that controls hardware as a low level. Occasionally, new versions of firmware may be issued to address particular issues. If you are not experiencing any issues, there is no need to upgrade your MX100 firmware. If the need should arise, your McIntosh dealer has access to the latest firmware.
Firmware Update is used to install new firmware. The new firmware should be unzipped on the root directory of a properly formatted USB drive (FAT or Fat32). The USB drive should be inserted into the USB port on the rear of the MX100. Selecting the Update Now button will begin the process.
It is highly recommended that your McIntosh dealer perform the update process since failure to properly install the firmware can leave the MX100 in an unusable state.
Factory Reset will restore the MX100's defaults. Any changes made will be lost. Configurations can be saved and restored in the "Save and Load" section of the General Setup menu.
MX100's Audyssey information is saved with Configuration backups. Audyssey should be re-run anytime a significant change is made in your system or its environment.
To Save the Configuration using the Web Page/Browser interface, select the Save Configuration button. Choose the destination to store the file. A file named "MX100_config.cfgs" will be created. If you choose, you can rename this file and save different setup configurations. Note that configurations created using the Web Page/Browser interface must be restored using this interface and CAN NOT be restored using the MX100's Front Panel interface or MX100's USB port.
If you wish to store to a USB drive in the MX100's
USB port, you must use the Front Panel interface.
To use the Front Panel interface to Save the Configuration:
- Insert a USB Drive in the MX100 USB port
- Go to the Save and Load submenu, and select Save
Two files are created when using the Front Panel to save to a USB drive in the rear of the MX100:
• AUDSY.MEQ which contains the Audyssey filter information
- MX100.CFG which contains the custom MX100 settings
To load a saved Configuration, select the Load Configuration button. Choose saved configuration file from its location either from a folder on your computer or a USB drive inserted into the computer's USB port. Configuration files by default are named "MX100_config.cfgs". Choose this file or a file you have custom named. Select open. The interface will say "Upload Complete" and the MX100 will power cycle and the new settings will be loaded.
If you are using the Front Panel to Load a Configuration:
Insert the USB Drive with the configuration file stored in the root directory in the MX100 USB port Go to the Save and Load submenu and select Load. Progress will be displayed for loading the two configuration files. The MX100 will power cycle when complete. The restored settings will be in effect.
Trigger1 and Trigger2 can each be set to power on/off components connected via a Power Control Cable (see “Power Control (Trigger) Outputs” on page 12).
Each Trigger can be set to:
- Independent allows each individual Input to be set to On or Off. When an Input that is set to On is selected, connected components will receive a Power Control signal to Power On until the selected Input is changed (to an Input that is set to Off) or the MX100 is powered Off.
- All On sets the Power Control setting of all Inputs to On. With this selection, any Input will generate a Power Control signal to be sent for that Trigger. All On is a quick way to change all the Inputs to On. You can switch to Independent to set any individual Input to Off.
- All Off sets the Power Control setting of all Inputs to Off. With this selection, no Input will generate an On signal for the Trigger. All Off is a quick way to change all the Inputs to Off. You can switch to Independent to set any individual Input to On.
When Independent is selected, you can select On or Off for these Inputs:
• HDMI1
• HDMI2
• HDMI3
• HDMI4
- HDMI TV
• Optical1
- Optical2
- Coaxiall
- Coaxial2
If set to Independent, Trigger2 has an additional Input option:
- ARC

RCLock when enabled (On) will prevent the front IR sensor from receiving IR commands from a Remote Control. The default for RCLock is Off. For more information regarding IR Inputs, see “Wired IR Inputs” on page 11.
Auto Off, when Enabled, the MX100 will power off after 30 minutes of no input. If you pause a movie for more than 30 minutes and you do not want to find the MX100 powered off, you would want to Disable Auto Off.

Before proceeding with Audyssey Auto Setup, it is very important to first go into the Amp Assign submenu of Setup to establish the correct settings for your specific Loudspeaker complement and location in the Home Theater Room. The Audyssey submenu has a button for the Amp Assign submenu so you can confirm your settings. This will not only assure the best acoustic performance using Audyssey Room Equalization Correction, but it will also assure the best sonic performance using the latest in surround sound technology built into the MX100. The acoustic characteristics of the connected speakers and listening room are measured and the optimum settings are made automatically.
Audyssey Procedure Overview
- Complete Amp Assign (see “Amp Assign” on page 18)
- Connect assembled Microphone (see Figure 21)
-
Place Microphone in the Focus Position (see Figure 19)
