Description
The DPA-DAC4 accessory card is designed to work in conjunction with DPA Series 4-channel
ampliers. The DPA-DAC4 is a 4-input Dante
™
receiver that features digital audio transportation over
standard IP networks. The DPA Series 4-channel ampliers come standard with four balanced line
inputs and an accessory card slot to add an additional 4-inputs, giving the amplier a total of 8-inputs.
All inputs can be mixed and routed to any of the four amplier channels. All four amplier channels
have an assortment of DSP tools including level controls, EQ’s, limiters, high & low pass lters, and
delay to provide exibility for a range of applications.

digital audio platform
• 4-channel receiver
• Integrates with 4-channel DPA Series amplifiers
Dante™ Overview
Audinate
®
created Dante
™
, an uncompressed, multi-channel digital media networking technology,
with near-zero latency and synchronization. Hundreds of Dante
™
-enabled products are available from
many manufacturers, enabling you to mix devices from multiple manufacturers.
One cable does it all. Dante
™
does away with heavy, expensive analog or multicore cabling, replacing
it with low-cost, easily-available CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and
economical solution. Dante
™
integrates media and control for your entire system over a single,
standard IP network.
Dante
™
systems can easily scale from a simple pairing of a console to a computer, to large capacity
networks running thousands of audio channels. Because Dante
™
uses logical routes instead of
physical point-to-point connections, the network can be expanded and reconfigured at any time with
just a few mouse clicks.
Since the signal audio is transmitted digitally, common analog challenges like interference from other
electrical equipment, crosstalk between cables, or signal degradation over long cable runs is not a
problem. Setting up Dante
™
networks is easy, even the most complex networks can be set up and
configured quickly and easily with Dante
™
, making system integration simple. Dante
™
automatically
handles the technical complexities.
Signal routing and system configuration with Dante
™
is fast, simple, and incredibly flexible. Dante
Controller
™
is a powerful software application that manages devices on the network. Setting up a
Dante
™
network is typically just a matter of plugging devices into an Ethernet switch and connecting
a computer to the network. All Dante
™
devices are automatically discovered and displayed in Dante
™
Controller, so a system can be up and running in seconds.
Visit www.audioinate.com for details or to learn more on using Dante
™
. There are many Dante
™
guides available in the industry. AtlasIED offers one in the BlueBridge
®
DSP section of atlasied.com.

Audio Applications
When installed, the DPA-DAC4 converts the DPA Series amplier into a digital audio network
amplier. The combination of the digital audio transport receivers along with integrated DSP makes
the DPA Series amplier the go to solution for a variety of applications including:
• Restaurants
• Government facilities
• Schools
• Industrial facilities
• House of worship
Selecting the dBFS Reference on the DPA-DAC4
The DPA-DAC4 comes with a choice of dBFS (Decibels Full Scale) gain selections of 0dBFS = 10dBu
and 0dBFS = 20dBu. Factory default for the card is 0dBFS = 20dBu. There is a 2-pin header on
the card that is the OdBFS gain selection. When a shunt is applied to the header, the 0dBFS = 20dBu
setting is engaged. When the shunt is removed the setting is 0dBFS = 10dBu. Most pro audio
equipment gains are in the range of 20dBu – 24dBu. Read the entire manual to understand these
settings.
Matching Gain from a Source to the DPA Series Amplier In a Dante
™
Network
Understanding the gain structure is very important to avoid clipping the audio signal or amplier
output. There are three potential ways to clip the signal chain.
1. Amplier Input Clipping - This occurs when the applied input signal exceeds the maximum input
level of the amplier input stage.
2. Amplier Output Clipping - Driving the amplier to maximum output level requires 0dBu or .775V
of signal when all level faders in the GUI are set to “0” or all up. Exceeding this level will cause the
amplier output stage to clip.
3. Digital Clipping - This occurs when the 0dBFS levels are exceeded. This is very important to
understand. Several examples are provided to help understand digital to analog gain structure.
Note: AtlasIED recommends to always place a limiter set for 0dB in the signal path prior to the
Network Output of the transmitting device. This is the best way to prevent clipping the DPA-DAC4.
Shunt on 0dBFS = 20dBu, factory default
Shunt off 0dBFS = 10dBu
