Introduction

The AtlasIED DPA amplifier series features a combination of flexibility, performance and control to provide high value features for applications that require more than just great sound. The network based DPA404 and DPA804 are DSP controlled four-channel amplifiers that can be configured in three different amplification arrangements to meet the design requirements of any installation. These DPA models are factory preconfigured in a four-channel 70V mode. If the design requires four channels of low impedance amplification, the DPA amplifiers can be configured as four-channel models with either 4-Ohm or 8-Ohm load impedances. Many system designs require both low and high impedance amplification. These DPA models can be configured to deliver 70V / 100V for a paging / background system on two channels plus two additional 4/8-Ohm amplifier channels for a foreground stereo application.

These DPA models come standard with four balanced line inputs and an accessory slot for an optional DPA-DAC4 four-channel Dante ^™ receiver card or a DPA-AMIX (2) mic / line, (2) AUX input card, giving the DPA404 and DPA804 a total of 8 inputs. All inputs can be mixed and routed to any of the four amplifier channels. All four amplifier channels have an assortment of DSP tools including level controls, EQ's, limiters, high & low pass filters, and delay to provide flexibility for a range of applications.

DPA Series amplifiers feature either local or network control making them a true "game changer" in the commercial audio world. The output level can be assigned to either the front panel potentiometers or to the onboard GUI. Wired remote level control and input select can be configured to allow simple control for the end user. Each unit also features GUI based input and output level metering along with assignable mute functions that are triggered via an audio signal or contact closure. Access to the DSP settings is accomplished via computer, tablet or mobile device using a web browser. All settings can be password protected.

The DPA series amplifiers also include PC based site manager software that automatically searches within a specific network for all DPA amplifiers on the network. It will list them and allow single click access to any unit. The DPA Site Manager software can do a variety of functions besides locating IP addresses including fault reporting, input & output status, standby status and remote activation via a scheduler timer.

The DPA404 and DPA804 are ready to use, out of the box in four-channel 70V / 100V mode, with no configuration or network connectivity required making them a cost effective solution even for applications that do not require processing or network control.

1. Power Switch

This toggles the amplifier between Active Mode or Sleep Mode. Refer to section "Understanding the 3 Amplifier Idle States".

2. LED Power Indicator

The DPA amplifier has three states of Idle power that are indicated as follows:

A. Idle Active Mode - When the LED outer ring of the power switch illuminates a steady blue color, the amplifier is in Active Mode and is ready to pass audio.
B. Sleep Mode - When the outer ring LED is Off, the amp is in Sleep Mode. In Sleep Mode, the Ethernet is active for access to the amplifiers on board GUI. The amplifier output stage and DSP is off. Audio will not pass in Sleep Mode.
C. Standby APD Mode - When the amplifier Auto Power Down (APD) is enabled and the amplifier is in the APD mode, the LED outer ring will blink blue once every 5 seconds.

For further information refer to section "Understanding the 3 Amplifier Idle States" on page 35.

3. Operating Mode Indicators

The DPA four-channel amplifiers can be configured three ways. The LEDs in this area indicate the configuration of the amplifier. These indicators illustrate if Channels 1/2 and 3/4 can be operated separately in 4/8Ω mode or 70V / 100V mode. Amplifier operation mode setting is completed using the internal DSP GUI.

A. 4-Channel High impedance 70V / 100V mode

B. 4-Channel Low impedance 4Ω or 8Ω mode
C. 2-Channel High impedance 70V / 100V mode & 2-Channel Low impedance 4/8Ω mode

4. Channel 1, 2, 3, 4 Signal LED

The Signal LED will illuminate green if audio signal is present at the Output of the amplifier.

5. Channel 1, 2, 3, 4 Limit/Protect/Mute LED

The Limit / Protect LEDs will illuminate Red if one of the following conditions occurs.

A. Any channel of the DPA amplifier reaches maximum output power. The DPA features an adjustable amplifier OUTPUT limiter which helps prevent the amplifier from hard clipping. An occasional flash of the LED is OK but if the LED illuminates continuously reduce the input level of the amp. If the Clip LED remains On after reducing the input level, recheck the load connected to the amplifier.
B. The OUTPUT has been Muted in the GUI.
C. A fault is detected within the amplifier. Once the fault is corrected, it may be required to reset the AC Mains power to reset the amplifier protect mode.

7. Air Exhaust

Each model includes convection cooling with dynamic fan assist for extreme conditions. If the unit is not being used or in Standby mode, the fan is not needed for cooling and remains Off until the unit is in heavy use. As heat is generated in the amplifier during use, the fan activates at a low speed and increases as needed to keep the amplifier at safe operating temperature. This cooling method eliminates the need for air filters that can become clogged and require maintenance. The DPA amplifier's air flow is from rear to front.

Accessing the GUI Control Panel

DPA amplifiers include a unique set of features and configurations. All DPA amplifiers are configured from the factory out of the box to operate as traditional commercial power amplifiers. Ethernet connectivity is not required for operation of a DPA amplifier. However, to take full advantage of the DSP settings such as, EQ, High & Low Cut filters, level control / assignment and limiter settings, the DPA Control Panel must be accessed via the network or local computer. External software is not required to operate the DPA amplifier; the software is embedded in the amplifier in what is called the web browser GUI Control Panel interface. To access the onboard control panel, follow one of the five methods listed below.

Accessing the GUI Control Panel

I. Direct Connection via Ethernet
II. Web Browser via Network Router
III. AtlasIED DPA Site Manager Software
IV. Smartphone or Tablet
V. Accessing the DPA Outside the Local Network

I. Direct Connection via Ethernet

Use this method if there is no network access available.

1. Connect an Ethernet cable from a laptop or desktop computer to the Ethernet Input on the DPA amplifier. Most computers will allow direct connection from the DPA amplifier using a standard CAT5 cable. Some older computers may require the use of a Crossover cable to connect to the DPA amplifier. If a connection cannot be made using a CAT5 cable, use a Crossover cable.
2. Turn OFF the computer's Wi-Fi.
3. Open a Web browser, AtlasLED suggests using Google Chrome or Mozilla Firefox.
4. In the Web Browser address bar, type in the following: http://DPA804 and hit enter. For this example we are connecting to the DPA model DPA804. An example is shown in Figure 1.

New Tab http://dpa804

Figure 1

1. Out of the box the amplifier's model number is all that is needed to connect. It is not case sensitive, but the full exact name is required. Note: During configuration, the amplifier's name can be changed. As an example at a school the amp may be renamed "ROOM1". After the name is changed, follow the same process to log onto the amp as outlined above, but change the name from "http://dpa804" to "http://room1".

2. The amplifier will be discovered and the DPA User PC Control Page will launch after pressing the "Enter" key. An example of the DPA User PC Control Page GUI web page is shown in Figure 2.

3. The DPA amplifier's IP address can be directly entered into the Web Browser to access the DPA GUI.

Example: "http://192.168.1.110".

Note: It is required to enter the Administrator Name and Password to access the home page. Factory default for User Name is "admin" and the password is "admin".

Note: When on the Mobile Page, on the Setup page, the faders will not function. To make setting changes the value of change must be entered in the data box. In the amp configure page the Level faders can be linked together for stereo level adjustment.

This method is very similar to the Direct Connection method covered in Section 1, but using a web browser on your local network to find the DPA amp.

1. Connect the DPA Amplifier using a standard Ethernet cable to a Router. Make sure the Router is in DHCP mode, the usual default.
2. Connect your computer to the same Router via an Ethernet cable or Wi-Fi.
3. Open a Web browser, AtlasLED suggests using Google Chrome or Mozilla Firefox.
4. In the Web Browser address bar, type in the following: http://DPA804 and hit enter. For this example we are connecting to the DPA model DPA804. An example is shown in Figure 1.
5. Out of the box the amplifier's model number is all that is needed to connect. It is not case sensitive, but the full exact name is required. Note: Once connected, the name of the amplifier can be changed to meet the install's naming orientation.
6. The amplifier will be discovered and the DPA User PC Control Page will launch after pressing the "Enter" key. An example of the DPA User PC Control Page GUI web page is shown in Figure 2.
7. If the DPA Amplifier's IP address is known, enter the IP number into the Web Browser to access the DPA GUI. Example: "http://192.168.1.110"

III. AtlasIED DPA Site Manager Software

This method is the easiest way to find and connect to any DPA Amplifiers on the Network. See Figure 3.

1. Download the DPA Amplifier Site Manager software at https://www.atlasied.com/SoftwareLibrary.
2. The DPA Amplifier Software is a small zip file and can be emailed but has to remain a zip file because it has an executable (.exe) file to launch the software. Most Internet security software will block any .exe file unless it is in zip file format. Also download the DPA Amplifier PC IP Site Manager Software user guide to make installation easier.
3. The DPA Site Manager software can do a variety of functions besides locating IP addresses such as; fault reporting, input & output status, standby status and remote activation via a scheduler timer. Refer to the DPA Site Manager instructions for the complete capabilities of the software.

1. After accessing the Mobile web page, the IP connection can be saved to the device's screen as APP ICON short cut where its name can be changed to reflect its location or other description.

Apple ^® iOS

• Open the DPA amplifier mobile web page using Safari.
• At the bottom of the screen select the box with the arrow.
• Select "Add to Home Screen"
• Open the DPA amplifier mobile web page using the Safari browser.
• Press the Menu button and select Bookmarks.
• Select the top left thumbnail labeled Add.
• Press OK to add it.

V. Static IP - Accessing the DPA Outside the Local Network

Follow these instructions in order to access a particular DPA amplifier from another network not connected to the DPA amplifier(s).

Example: An amplifier is in a school in Los Angeles and the volume in the classroom is not loud enough. The installer has the maximum level set via the limiter. Instead of the installer having to drive to the school which is three hours away, he can access the amplifier from his desk or phone. During the installation of the amp, the amplifier can be configured with a static IP address and a specific port assigned by the school's IT manager. This enables the installer access only to the specific DPA amplifier that needs the level adjusted. Below is a safe convenient way to allow limited access to a specific product via a protected network. Setting up an external IP address eliminates the requirement to VPN into a network to gain access to the LAN. This allows the person needing to maintain the device a single point of entry and keeps the LAN secure.

1. Plug DPA amp into local network, determine the IP address assigned to the amp, and change it to a static IP address.
2. Create a NAT (Network Address Translation) on the WAN router or firewall using port 80. An external static IP address will be needed for this process to work.
3. Once the external IP address is translated to the internal IP address, go to another Internet connection outside the Local Network where the DPA amp is present and try connecting to the external IP address. Verify correct NAT has been established.

This link is an example of a DPA804 amplifier connected to a Network that allows access from the Internet. Type this link into a web browser to access a live demonstration: http://dpa1202demo.atlasied.com. After connecting to the DPA amp, click the Setup tab and enter the USER NAME (admin) and PASSWORD (admin) to gain full access of the amplifier.

Resetting the DPA IP to Factory DHCP

1. Remove AC Power from DPA amp and wait 1 minute
2. Apply AC while at the same time, press and hold the front power button until the LED blinks 5 times at which point it will be reset. Note: typically the button must be held for about 10 seconds.
3. DHCP will be enabled
4. Follow standard login procedures

Mute, Link & Port Assignment Page

This page allows you to view the amplifiers configuration and assign VOX Mute & Contact Closure Mute, Remote Level and Link Level Faders.

1. Output Configuration Indicators - This section is a visual aide to see how the amplifier is configured. This is important information to know when assigning a Remote Level or Linking Faders.
2. Remote Level Assign - This section allows the user to assign the Control Port on the rear of the amplifier to control the amplifier output selected by the user. Note: Factory Default C1 is assigned to control Output 1, C2 controls Output 2, C3 controls Output 3, and C4 controls Output 4. Refer to Page 27 for information on configuring and wiring a remote level control.
3. Auto Sense Input Mute (VOX) - This section allows the user to assign a selected input to be a Mute Send trigger when it senses an input signal. It will then send a Mute command to other inputs that are assigned to receive the mute command. There are two levels of priority that can be assigned. Refer to Page 30 for information on how to set up a VOX Auto Sense Mute.
4. Audio Sense Trigger Threshold - Audio levels vary and are dependent on the source material. Levels from a CD vary from a microphone. In the GUI the level to activate or trigger the Mute can be selected in 1mV increments up to 50mV. When setting the trigger level you need to allow for noise on the audio line and set the level high enough to avoid false triggers. The level sent applies to Mute Send #1 / Mute Receive #1 and Mute Send #2 / Mute Receive #2.
5. Mute / Duck Hold Time - How long or how much the selected input needs to be muted and reduced in level (Duck) will depend on the application. In the GUI there are four selections to choose from. Refer to Page 31 for information on selections. Note: This setting applies to both the Audio Sense Trigger and the Contact Closure Mute:
6. Contact Closure Input Mute - A rear panel control port can be assigned to mute any Input as seen in the Mute, Link, and Port Assignment GUI page shown below. A remote switch can be used to control the mute trigger as shown in the illustration below. Refer to Page 31 for setup.
7. Input Level Control Link Assign - The DPA amp has 4 line inputs with an additional optional 4 inputs. Some of the Inputs or Outputs may be used for stereo applications. For control convenience you can assign two faders to be linked together.
8. Level Control Assignment Indicators - This section displays a combination of settings gathered from other pages. This allows the user to see which Inputs are assigned to what Output, Input Names and if faders are linked together while making other configuration settings. The example below shows that Input 1 is assigned to Output 1, Input 2 is assigned to Output 2, Input 3 is assigned to Output 3, and Input 4 is assigned to Output 4. The amps are configured as 4 CH 70V / 100V amplifier and no Inputs are linked together. This is also the factory default setting.

Remote Level Control Port Assignment & Wiring

Remote level control can be accomplished by wiring an external 10kΩ potentiometer to the Control Port on the rear of the DPA Amplifier. Assign a Control Port pin to the amplifier channels that need to be level controlled remotely. The Remote Level topology is a VCA +10VDC based system. AtlasLED recommends using the optional AtlasLED WPD-VC10K wall control. Set the system's maximum levels using the amplifiers internal level controls and then use the remote 10KΩ potentiometer as an attenuator from the amplifiers preset level that was set on the front panel level controls or the internal GUI levels. Each WPD-VC10K will require using three conductor wire connecting the WPD terminals to the amp Control Port. Maximum distance can be up to 500 feet. Follow these steps before starting.

1. Decide how the amplifier output channels are to be configured for the install. There are three different amplification arrangements to meet your design requirements. Refer to the section on "How to Configure The DPA Amplifier Output Channels"

Input Mute Assignment

The DPA amplifiers offer two methods to trigger or activate an Input Mute. Combining the features of the Input Mute assignment with the I/O router allows the ability to assign paging or make announcements to a particular zone or multiple zones. Many installations require an emergency override, requiring all inputs to be muted except for the emergency page. Mute trigger or activation can be accomplished via an external Contact Closure (CC) or by sensing the audio signal on a particular assigned input.

A. Audio Signal Sensing Mute (VOX): The DPA Series offers two priority levels of VOX muting. The Send or Receive assignment is done in the Mute, Link and Port Assignment GUI page as shown below. Any Input can be assigned to Mute any other input. Follow the steps below on how to set up VOX mute.

Audio Sense Input Mute Mute Send Mute Receive Input 1 Input 1 Input 2 Input 2 Input 3 Input 3 Input 4 Input 4 Input 5 Input 5 Input 6 Input 6 Input 7 Input 7 Input 8 Input 8 Trigger Threshold 50mV

Figure 28 Figure 29

1. Assigning the Audio Sense Mute Send - Select the input desired to be the trigger input. This is known in the GUI as Audio Sense Mute Send. Usually this input is the main paging input. The DPA offers two levels of Mute Send and Mute Receive assignment. Note: Only select one Mute Send per priority of #1 or #2. Start by selecting the Input you want to be Mute Send #1 audio signal trigger.
2. Assigning the Audio Sense Mute Receive - Select the inputs desired to receive the Mute command from the Input selected, the Audio Sense Mute Send. All channels can be selected to receive the Mute command except for the same associated Input. In other words Mute Send #1 Input 1 cannot be assigned to Mute Receive #1 Input 1. Note: Mute Send #1 / Mute Receive #1 and Mute Send #2 / Mute Receive #2 correspond to each other.
3. Setting the Audio Sense Trigger Threshold - Audio levels vary and are dependent on the source material. Levels from a CD vary from a microphone. In the GUI the level at which the Mute is activated or triggered can be selected in 1mV increments up to 50mV. When setting the trigger level allow for noise on the audio line and set the level high enough to avoid false triggers. The level set applies to Mute Send #1 / Mute Receive #1 and Mute Send #2 / Mute Receive #2.

4. Setting the Mute / Duck Hold Time - In the GUI there are four selections to choose from for the mute duration and level reduction. Note: This setting applies to both the Audio Sense Trigger and the Contact Closure Mute.

5. Full Mute with a hold time of 1 Second

6. Full Mute with a hold time of 5 Seconds
7. 10dB Duck with a hold time of 1 Second
8. 10dB Duck with a hold time of 5 Seconds

1. Assigning the Contact Closure Mute Send - Select the Control Port to be the Mute Send trigger to Mute the inputs that are assigned Mute Receive inputs. This is known in the GUI as Contact Closure Mute Send.
2. Assigning the Contact Closure Mute Receive - Select the Inputs that are to receive the Mute command from the Control Port selected Mute Send. All channels can be selected to receive the Mute command.
3. Setting the Mute / Duck Hold Time - In the GUI there are four selections to choose from for the mute duration and level reduction. Note: This setting applies to both the Audio Sense Trigger and the Contact Closure Mute.
4. Control Port Wiring - After the Control Port has been assigned in the GUI, match the assigned port to the corresponding Control Port Pin on the rear panel of the DPA. To activate the Mute Send trigger Control Port Pins P1 – P4, a +10V source needs to be applied to it. This can be done by connecting a switch between the +10V to the assigned Mute Send P1 – P4 Control Port on the rear panel of the DPA as shown below. A remote +V source may be used and will require connecting the ground from two devices together. Wiring for this is shown below. Current requirements are very low, 2mA. Maximum wiring distances will vary with the wire gauge size used. It is typical to use 22-gauge wire to achieve distances over 500 ft.

Accessory Card Installation

The DPA404 and DPA804 offer four additional inputs that can be routed to any of the four output channels. Optional accessory cards DPA-DAC4 (4-Channel Digital Audio Input Card) and DPA-AMIX (4-Channel Analog Mic/Line, Auxiliary Input Card) are available. Contact AtlasLED for a list of available accessory cards. Note: Accessory card installation must be done by a qualified technician.

1. Remove the DPA Amplifier from the AC Mains source.
2. Remove the two screws (M3 x 8mm Pan Head Black) holding the DPA Accessory blank panel.
3. Remove the ribbon cable from the cover plate.
4. Connect the accessory card to the ribbon cable by carefully aligning the ribbon cable connector to the mating PCB connector. Do not force. If aligned correctly the cable will mate easily.
5. Carefully guide the accessory card into the slot without forcing the PCB or cable.
6. After the card is inserted and the accessory panel is flush to the chassis, align the two screws holes and secure them together by using the M3 x 8mm screws.

Installation and Considerations

Cabling - These amplifiers can be used with either balanced or unbalanced sources, provided the proper cabling is used. A balanced line is defined as two-conductor shielded cable with the two center conductors carrying the same signal but of opposite polarity when referenced to ground. An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.

Balanced Input - Use 20-22-gauge, 2-conductor shielded wire for low level signals. Maintain the proper polarity, + to +, - to - and shield to ground. For unbalanced signals using the Phoenix connector connect the (-) pin of the amplifier input to the GND center pin and the (+) pin to positive.

Speaker Outputs - Use 2-conductor unshielded wire of the appropriate gauge. The DPA Series is approved for Class 3 wiring. Contact AtlasLED Tech Support at 1-800-876-3333 if issues arise.

Placement And Mounting - Turn off all equipment before making connections. The amplifier can be mounted in a standard width 19' rack. It can be mounted above or below anything that does not generate excessive heat. Although the unit's chassis is shielded against radio frequency and electromagnetic interference, extremely high fields of RF and EMI should be avoided.

Ventilation - The amplifier should be situated so that its location or position does not interfere with its proper ventilation. For example, the DPA Series Amplifiers should not be situated in a sealed cabinet or on a shelf with obstacles that may impede the flow of air through the ventilation openings.

Heat - The DPA Series Amplifiers should be installed away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce excessive heat. Ambient temperatures should not exceed 113°F (45°C)

Understanding the 3 AC Power Consumption Idle States

The DPA amplifier has three states of Idle power consumption to meet the installation energy power consumption requirements. Refer to the amplifier specification page for power consumption data. Below is the definition how each idle state operates.

A. Idle Active Mode - When the LED outer ring of the power switch illuminates a steady state blue color, the amplifier is in Active Mode and is ready to pass audio.
B. Sleep Mode - If the outer ring LED is Off, the amp is in Sleep Mode. Sleep Mode allows the Ethernet to be active for access to the amplifiers on board GUI. The amplifier output stage and DSP is off. Audio will not pass audio in Sleep Mode. Press the front panel power switch to activate Idle Active Mode or press the AMP ON button in the amplifiers GUI to activate the amplifiers Active Mode. The LED outer ring of the power switch will illuminate a steady state blue color indicating the amplifier is in Active Mode.

Note: The DPA Site Manager software has a scheduler that can toggle the DPA amplifier between Active Mode and Sleep Mode. Sleep Mode is the most efficient power consumption mode of the DPA amplifier.

C. Standby APD Mode - When the amplifier Auto Power Down (APD) is enabled and the amplifier is in the APD mode, the LED outer ring will blink blue once every 5 seconds. When the amplifier is in the APD state the amplifier can be toggled into Active Mode by pressing the front panel power switch, selecting the AMP ON button in the GUI, or applying input signal. When the amplifier is activated, the LED outer ring of the power switch will illuminate a steady blue color.

3. Average Power is defined as Pink Noise input signal applied to achieve 1/4 of the 4 Ohm or 70.7V power rating.
4. Max Power is defined as 1 KHz input signal applied to achieve the maximum power output before clipping into a 4 Ohm or 70.7V load.
5. BTU is calculated by the AC Mains Power consumed minus the total power output measured at the specified load and condition, multiplied by 3.412.

Example: 785 Watts from the AC Source - 600 Watts Total Output power = 185 x 3.412 = 631 BTU
