A space-saving way to convert AES to analogue audio
The DACA214 is a dual channel AES/EBU to analogue audio converter.
24 bit processing, excellent noise and distortion figures and Crystal Vision’s sophisticated audio error masking together create a truly high quality output.
The competitively priced DACA214 offers two independent channels on a 100mm x 266mm module, therefore allowing 24 channels in 2U and making it the perfect audio converter for applications where available rack space is limited.
Use it with 75 ohm or 110 ohm audio
AES inputs can be 110 ohm balanced, high impedance balanced or 75 ohm unbalanced.
The DACA214 can accept signals with sampling rates anywhere between 30kHz and 50kHz, although a clock rate of 48kHz tends to be the case for most applications. Each input has a clock regenerator for 48kHz signals to ensure low distortion conversion and the highest quality output.
Adjust the audio level
Analogue audio output levels are conveniently preset to give either +18dBu or +24dBu for 0dBFS digital (the most common audio levels within television stations), or can be continuously adjusted from +12dBu to +28dBu.
Useful features
Other useful features include the option to swap stereo channels 1 and 2 and the ability to invert the phase of the right hand channel to correct phasing errors.
The DACA214 can even be converted to single channel operation if multiple outputs from a single stereo input are required.
A stereo headphone jack at the front of the board allows you to easily monitor the contents of each stereo pair.
Get the outputs you need
DACA214 is a 100mm x 266mm module which fits in Crystal Vision's Indigo frames, available in 2U, 1U and desk top box sizes – with up to 12 boards fitting in 2U.
It can be used with three different frame rear modules (the RM03, RM11 and RM12), with each giving two analogue stereo outputs per channel.
The RM03 and RM11 are used for 110 ohm AES inputs and the RM12 for 75 ohm.
Flexible control
There is a choice of control and status monitoring options to suit all tastes, including board edge, an integrated control panel on the AE frame, the VisionPanel remote control panel, SNMP, our ASCII and JSON protocols, the Statesman Lite PC Control System or the VisionWeb web browser control. Try the DACA214 VisionWeb demo...
GPI outputs can be set to raise an alarm on loss of AES input or sustained silence. The duration of silence before a warning is given can be programmed from 1.5 seconds to 120 seconds in eight second steps.

What outputs do I get?
Signal inputs and outputs are accessed by using an appropriate rear module.
The Indigo rear modules slot on to the back of the frame and typically feature BNC, D-Type, RJ45 and optical connectors. The single and double slot rear modules can be used with all three frame sizes, while the quad slot rear modules just fit the 2U frames.
There are three rear modules available for the DACA214...
