A space-saving way to convert analogue audio to AES
The ADCA412 provides exceptional 24 bit conversion from analogue audio to AES/EBU, giving out clear, noise-free audio.
With two independent channels this space-saving 100mm x 266mm module fits 24 converters in 2U, at a price comparable to other single channel products.
The ADCA412 is ideal for any environment where you need to convert from analogue to digital audio, especially multi-channel applications.
Use it with multiple data rates
The ADCA412 can be used with any sampling data rates between 30kHz and 50kHz, with most applications typically involving 48kHz sampling.
Flexible reference sources
It offers the flexibility to take the reference from three different sources: Black & Burst video (48kHz sampling only), another AES feed or word clock.
The crystal controlled phase locked loop ensures an extremely stable clock is generated at 48kHz even when referenced to video, resulting in the best possible performance.
Having the AES locked to video is especially useful for audio which may later be embedded into a video feed.
Output 75 ohm or 110 ohm audio
The ADCA412 is available in two versions, with the AES outputs configured as either 110 ohm balanced or 75 ohm unbalanced depending on which OPAES output module is fitted.
Adjust the audio level
Analogue audio input levels are 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
Powerful features include a channel swap function allowing channels 1 and 2 to be transposed, while the phase of the right hand channel can be inverted to correct phasing errors.
Should multiple outputs from a single stereo input be required, there is an option to convert to single channel operation.
Listening to each incoming analogue stereo pair is quick and easy: just insert headphones into the jack at the front of the board.
Save rack space
ADCA412 is a space-saving 100mm x 266mm module which is housed alongside any other Indigo product in the standard Indigo frames – available in 2U, 1U and desk top box sizes – with up to 12 boards (24 channels) fitting in 2U.
Get the outputs you need
The choice of five frame rear modules means you can choose the outputs you need for your application.
The RM03 and RM11 rear modules give four 110 ohm AES outputs per channel.
The RM13 rear module gives three 75 ohm AES outputs per channel with a Black and Burst loop-through, the RM14 four 75 ohm AES outputs per channel with a Black and Burst loop-through and the RM21 two 75 ohm AES outputs per channel.
Flexible control
Control and status monitoring on the ADCA412 is flexible and sophisticated. Options include board edge switches, 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 ADCA412 VisionWeb demo...
GPI functionality is especially useful, with available warnings including sustained silence – ideal for continuous feeds. The duration of silence before a warning is given can be programmed from 1.5 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 five rear modules available for the ADCA412...
