Introduction
This manual explains the DDR-16/32 AES67 Receiver/DAC setup and operation. It contains full
instructions for installing hardware and software, setting up audio playback and configuring the system.
The DDR-16/32 AES67 Receiver/DAC converts up to 24 channels of AES67 audio formatted signal to
up to 32 channels of balanced analog audio output. Output connector wiring is in Tascam format. It can
accept input streaming at 48kHz for 24 channels.
The DDR-16/32 is available in two configurations:
16 Channel output DAC (DDR-16)
32 Channel output DAC (DDR-32).
For output, any combination of DDR-16/32 output channels may be selected, and can have crossovers
set.
The rear panel Ethernet: Status/Control connector provides access to status, control and setup functions
thru a computer, using an internet browser.
The DDR-16/32 is designed to work seamlessly with the Datasat AP25 Audio Processor when the
optional H790 AES67 output card is installed. The H790 card supports streaming of up to 16 channels at
96kHz, and 24 channels at 48kHz. The H790 card also provides additional output channel mapping over
the Ethernet connection (24 channels total) for use in Bi-amping / Tri-amping, or to add additional
speakers to existing input channels. Please see appendix C for more information on the H790 card.
To get the most out of your DDR-16/32, we suggest that you review this manual and keep it available
during system installation and initial operation.
The DDR-16/32 utilizes Momentum Data Systems (MDS) EQ3-AoIP (Audio over IP) technology.
