let's talk about it.

The ADA4 is a 4-channel converter that can be configured as a 4-channel A/D, a 4-channel D/A, 2-channel A/D and 2-channel D/A, or an AES synchronizer.

Supplied Breakout Cable

The included breakout cable provides the audio connections for ADA4, allowing 8 channels of AES audio input and output while keeping the overall size of the Mini-Converter compact and portable.
