I have an older 2488. I recently bought an ART PROvII compressor/limiter. I've got no problems running instruments/vocal mics through the limiter then to the board. What I want to know is how can I interface the compressor to the stereo pre-mix and stereo master to get finished product? Also, I have two 2488s - does anyone know how to sync them together? I've tried following TASCAM's instructions, but can't seem to get it to work. Thanks!!
