BEHRINGER ADA8200 Used 8-channel A/D-D/A converter and microphone preamplifier. I have been using it as a microphone preamplifier. The sound quality and performance are not a problem at all, in fact, I like it, but I no longer use it because recording at 96K has become the standard for me. (This equipment is up to 48K) I haven't used it much in recent years, keeping it as a spare. It was only used in a non-smoking studio and has never been taken outside. All channels have been tested and confirmed to be working. The appearance is as shown in the photos, with some scratches and signs of use. As a bonus: - Audio-Technica ADAT cable - Canare clock sync cable These are the combinations I have used for many years without any problems.
