Datavideo AD-300 Pro Audio Delay Box

The AD-300 is the rack answer to the delay problem: three balanced stereo inputs on XLR and 1/4 inch, two unbalanced RCA pairs, and up to 3000ms of adjustable delay to pull audio back behind a long video chain. Everything is set from a 2 inch LCD rather than by feel, so a change made in rehearsal is repeatable on the show.

Beyond delay it carries the processing a small production usually has to borrow from a console: mixing, equalizer, compressor, limiter, gate, expander and filter. Outputs are two balanced XLR stereo pairs plus two RCA pairs and a 3.5mm headphone jack for local monitoring. It runs on 12V DC at 13.8W and mounts in a rack with the optional RMK-1 kit.
