The AtlasIED DPA-102PM is a compact 2-channel Class-D power amplifier with onboard DSP and Ethernet network control, designed for commercial AV, installed sound, and projector-based audio systems. It delivers 50 watts per channel at 8Ω or 100 watts per channel at 4Ω, providing up to 200 watts of total output into compatible low-impedance loudspeakers.

Integrated DSP provides control over input and output levels, limiting, parametric EQ, high- and low-cut filters, delay, and signal routing. An onboard web server allows DSP functions, amplifier levels, output status, and other settings to be accessed over an Ethernet network.

The DPA-102PM can also operate out of the box without network configuration, making it suitable for systems that need straightforward amplification as well as more advanced installations requiring DSP and remote control.

2-Channel Class-D Amplification

The DPA-102PM provides two channels of Class-D amplification with the following output ratings:

• 50W per channel at 8Ω
• 100W per channel at 4Ω

The factory configuration operates as a two-channel 4Ω amplifier with front-panel level controls active and the DSP set flat at 0 dB.

Its compact half-rack chassis provides two-channel amplification while conserving equipment space in commercial AV installations.

Fully Configurable Onboard DSP

The DPA-102PM includes integrated digital signal processing, eliminating the need for a separate DSP in many smaller installations.

Available DSP functions include:

• Input level control
• Output level control
• Output limiting
• 5-band parametric EQ per channel
• High-cut filters
• Low-cut filters
• Up to 60 ms delay per channel
• Matrix mixing

These tools allow the amplifier to be configured for different loudspeakers, room requirements, signal-routing needs, and installed audio applications.

Ethernet Network and Web Browser Control

Built-in Ethernet connectivity allows the DPA-102PM to be monitored and configured over a network.

The onboard web interface provides access to DSP functions and level controls while also allowing amplifier output level and status to be monitored remotely.

For a single amplifier, the onboard web interface can be used without dedicated PC configuration software.

The DPA-102PM also supports network auto-discovery and AtlasIED DPA monitoring software for systems incorporating multiple compatible amplifiers.

Local and Remote Level Control

Front-panel level controls provide convenient local adjustment and can be assigned as required.

The knobs are removable and protected by a security cover to help prevent unauthorized adjustment after the system has been commissioned.

Remote wired level control is also supported using a 10kΩ-based control, with a separate return for each channel.

Balanced and Unbalanced Inputs

The DPA-102PM accommodates both professional balanced and unbalanced audio sources.

Input sensitivity is 750 mV for both connection types, with:

• Balanced input via Euroblock/Phoenix-style connector
• Unbalanced input via RCA
• 20kΩ balanced input impedance
• 10kΩ unbalanced input impedance

This allows the amplifier to integrate with a variety of commercial AV source equipment.

Automatic Audio Power Down

The DPA-102PM incorporates Audio Power Down (APD) functionality to reduce power consumption when the system is not being used.

The specified trigger threshold is 5 mV, with the amplifier entering standby after approximately 30 minutes without a detected audio signal.

Standby power consumption is approximately 1 watt while Ethernet remains active.

Why Choose the AtlasIED DPA-102PM?

The DPA-102PM combines two-channel Class-D amplification, configurable DSP, and Ethernet-based control in a compact half-rack chassis.

Unlike a basic commercial power amplifier, the DPA-102PM provides onboard EQ, limiting, filtering, delay, matrix mixing, remote monitoring, and network control. It can also be used without network configuration when those advanced functions aren't required.
