The DACA214 is a dual 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.

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.

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.

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.

DACA214 is a 100mm x 266mm module which fits in Crystal Vision's standard frames.

It can be used with four different frame rear modules (the RM03, RM11, RM12 and RM35), with each giving two analogue stereo outputs per channel.

The 'easywire' RM35 features its audio connections on a 64-way DIN 41612 connector which stretches the full width of the rear module and therefore gives more room to solder the wires on to the individual pins. The RM03, RM11 and RM35 are used for 110 ohm AES inputs and the RM12 for 75 ohm.

There is a choice of control and status monitoring options to suit all tastes, including board edge, an active front panel on the frame, a remote control panel, SNMP or the Statesman PC Control System.

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.
