Atlas Sound DPA-DAC4 – Dante Network Accessory Card for DPA Amplifiers

Product Overview

The AtlasIED DPA-DAC4 is a 4-channel Dante network audio accessory card designed for installation in AtlasIED DPA Series 4-channel amplifiers, expanding their input capability from four balanced line inputs to eight total inputs by adding four Dante network audio channels. This Dante amplifier expansion card enables DPA Series amplifiers to receive audio over standard IP networks, making it a practical upgrade for commercial AV installations that have adopted or are transitioning to networked Dante audio infrastructure.

Product Description

The DPA-DAC4 plugs into the dedicated accessory card slot on DPA Series 4-channel amplifiers, providing four Dante network audio receiver channels via a single RJ-45 Ethernet connection. Once installed, all eight inputs — four original balanced line inputs plus four Dante inputs — can be freely mixed and routed to any of the four amplifier output channels. The amplifier's on-board DSP tools, including level controls, parametric EQ, limiters, high-pass and low-pass filters, and delay, remain fully available across all input and output configurations, providing the processing flexibility needed for conference room, training room, and distributed audio system deployments.

The Dante standard enables digital audio transport over standard IP networks using off-the-shelf network switches, eliminating the need for dedicated audio cabling between sources and the amplifier in networked installations. The DPA-DAC4's gain controls are PCB shunt selectable between 0 dBFS = 20 dBu and 0 dBFS = 10 dBu, allowing the installer to match the card's digital-to-analog reference level to the signal levels in the system. Frequency response is 20 Hz to 20 kHz (+/- 1 dB) with THD of 0.06% at 1 kHz — performance specifications appropriate for commercial speech and music reinforcement applications. The card is compact at 0.97 x 4.70 x 2.5 inches and weighs just 2.6 ounces, adding minimal size or weight to the host amplifier. A 12-month warranty applies.

Key Features

• 4-Channel Dante Network Audio Input — Receives four channels of Dante audio over standard IP networks via a single RJ-45 port, eliminating point-to-point analog audio cabling for networked sources.
• Expands DPA Series to 8 Inputs — Adds four Dante inputs to the existing four balanced line inputs of DPA 4-channel amplifiers, for a total of eight freely routable input channels.
• Full DSP Access on All Channels — All amplifier DSP tools (EQ, limiters, high/low pass filters, delay, level controls) remain available across all eight inputs and four output channels after card installation.
• PCB Shunt-Selectable Gain Reference — Gain reference switchable between 0 dBFS = 20 dBu and 0 dBFS = 10 dBu to match system signal levels without external attenuation.
• Standard IP Network Integration — Connects to Dante audio networks via standard RJ-45 Ethernet and commercial network switches, compatible with existing IT infrastructure.
• Wide Frequency Response — 20 Hz to 20 kHz (+/- 1 dB) frequency response with 0.06% THD at 1 kHz, appropriate for commercial speech and music reinforcement.
• Compact and Lightweight — At 0.97" x 4.70" x 2.5" and 2.6 oz, the card adds negligible size or weight to the host DPA Series amplifier.

Typical Applications

• Conference room Dante audio system expansion
• Boardroom networked audio distribution
• Training room multi-source audio routing
• House of worship Dante infrastructure integration
• All-hands room networked AV system
• Commercial multi-purpose room distributed audio

Frequently Asked Questions

Q: Which amplifiers is the DPA-DAC4 compatible with?

A: The DPA-DAC4 is designed specifically for AtlasIED DPA Series 4-channel amplifiers that include an accessory card slot. Confirm the specific DPA model in your installation includes an accessory slot before ordering.

Q: Does the DPA-DAC4 require special network infrastructure?

A: No. Dante audio uses standard IP networks and commercial network switches. No dedicated audio cabling or proprietary network hardware is required beyond a standard managed or unmanaged Ethernet switch appropriate for your network design.

Q: How many total inputs does the DPA amplifier have after installing the DPA-DAC4?

A: The DPA-DAC4 adds four Dante inputs to the DPA amplifier's existing four balanced analog line inputs, for a total of eight inputs, all freely mixable and routable to any of the four amplifier output channels.

Q: What DSP features are available after installing the DPA-DAC4?

A: All DPA Series DSP tools remain fully available across all eight inputs, including level controls, parametric EQ, limiters, high-pass and low-pass filters, and delay on each of the four amplifier output channels.

Q: How is the gain reference level selected on the DPA-DAC4?

A: The gain reference is set via a PCB shunt jumper on the card itself, selectable between 0 dBFS = 20 dBu and 0 dBFS = 10 dBu to match the signal levels in the installation without external padding.

Q: What is the warranty on the DPA-DAC4?

A: The AtlasIED DPA-DAC4 carries a 12-month limited warranty from date of purchase, which is shorter than most AtlasIED speaker and enclosure products that carry a 5-year warranty.
