Frequently Asked Questions - DPA602 Atlas Sound

How do I connect speakers to the DPA602?

Connect speakers to the output terminals on the rear panel. For low-impedance (4Ω/8Ω) use the corresponding terminals. For 70V/100V distributed systems, use the high-impedance output and ensure total speaker wattage does not exceed the amplifier's rated power.

What types of input sources can I use?

The DPA602 accepts microphone (XLR), line-level (RCA), and auxiliary (3.5mm) sources. Microphone inputs have built-in preamps; line inputs are for devices like media players or mixers.

Why is there no sound from my amplifier?

Check that the amplifier is powered on (green LED), the master volume is turned up, speakers are properly connected, and the correct input source is selected. Also verify that the source device is outputting audio.

Can I use this amplifier for outdoor paging?

Yes, the DPA602 supports 70V/100V distributed audio, ideal for outdoor paging systems. Ensure all outdoor speakers are rated for the voltage and have proper weatherproofing.

How do I adjust the tone (bass/treble)?

Use the bass and treble controls on the front panel to shape the audio. Adjust clockwise for boost, counterclockwise for cut. Center position (detent) is flat response.

What is the maximum number of speakers I can connect?

This depends on speaker impedance and power rating. For 70V systems, calculate total speaker tap wattage to not exceed 60W. For 4Ω speakers, use two in parallel (2Ω total) is not recommended; use 8Ω speakers in parallel for 4Ω load.

DPA602 / DPA1202 / DPA2402

Owner's Manual

Introduction

The AtlasLED 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 DPA602, DPA1202 and DPA2402 are DSP controlled 4-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 two-channel 70V mode. If the design requires four channels of low impedance amplification, the DPA amplifiers can be configured as 4-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 a single channel 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 4-channel Dante "receiver card or a DPA-AMIX (2) mic / line, (2) AUX input card, giving the DPA602, DPA1202 and the DPA2402 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" with amplifiers in the commercial audio world. The output level can be assigned to either the front panel potentiometers or to the on board 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 a single click access to any unit. 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.

The DPA602, DPA1202 and the DPA2402 is ready to use, out of the box for two 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. 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 state 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 19" rack models are four-channel amplifiers that can be configured three ways. The LED's 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 if they are combined making a 70V / 100V output. Amplifier operation mode setting is completed using the internal DSP GUI.

A. 2-Channel High impedance 70V / 100V mode
B. 4-Channel Low impedance 4Ω or 8Ω mode
C. 1-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.

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

Follow these instructions in order to access a particular DPA amplifier from outside of the Network the DPA is connected to. 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.

Resetting the DPA IP to Factory DHCP

1. Remove AC power from the DPA amplifier and wait 1 minute.
2. Apply AC power. The blue power indicator will turn solid after 1 - 2 seconds. Immediately press and hold the power switch until the blue power indicator turns off then back on. All of the front panel LEDs will blink a few times. After the LEDs stop blinking, release the power switch. After the power indicator illuminates solid blue, you are now able to log in using "admin" for the Username & Password.
3. DHCP will be reset and both the username and password will be reset to "admin." Note: The DSP settings will not be affected.
4. Follow standard login procedures. See page 17.

Remote Level Control Port Assignment & Wiring

Remote level control can be accomplished by wiring an external 10k 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. AtlasIED recommends using the optional AtlasIED 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"

Figure 20
Figure 20

1. After configuring the amplifier output channels choose which channels to remotely control. This will be dependent on the amplifier configuration and installation requirements. If the factory default settings do not meet the installation requirements, configure / assign the output channels desired to control in the "Mute, Link & Port Assignment" page in DPA GUI. Select the Port and Output Channel desired to remotely control.

Input Mute Assignment

The DPA Amplifier Series offers 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 offer 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.

Figure 32

Figure 33

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 in which to the Mute to activate or trigger 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

Input Mute Assignment

B. Mute (Contact Closure) Port Assignment - 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. Follow the steps below to set up a Contact Mute function.

Figure 34
Figure 35

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 assign 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. If you want to use a remote +V source you may be required to connect the ground of the 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 DPA602, DPA1202, and DPA2402 offer 4 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 AtlasIED for a list of 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 - The DPA Series 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 AtlasIED 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's 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 weekly scheduler timer 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 state blue color.

120V & 220V Operation

The DPA Series is designed to operate from 110V - 120V & 220V - 240V. All amplifiers will sense the AC Mains voltage and automatically change voltage internal settings. There are no internal or external switches for AC Mains voltage change over.

A. DPA602 and DPA1202 use the same fuse for both 120V & 230V operation. No need to change the fuse type.
B. DPA2402 - Use the fuse T12AL 250v, 12A, Slow Blow, 5mm x 20mm, Ceramic, LITTELFUSE #: 215012 for 120V Operation. This fuse ships installed in the amplifier.
C. DPA2402 - Change the fuse to T6.3AL 250v, 6.3A, Slow Blow, 5mm x 20mm, Ceramic, LITTELFUSE #: 21506.3P for 230V Operation. This fuse is included in the shipping carton.

Note: All fuses must be changed by a qualified technician. Always remove the amplifier from the AC mains before changing the fuse.

NOTES:

1. Power level measurement is defined as follows: 1Hz Sine wave signal burst of 20 cycles (20mS) at 1% THD+N, followed by 480 cycles of a 1kHz sine wave at 10% of the max power. Other power measurements are available upon requests.
2. Power measurement with Ethernet connected. Without Ethernet connected deduct .2W
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
