The ADA 8000 takes a while (0.5 second) to output any audio after you press play. The digital to analogue converters automatically mute audio after a period of digital silence, and take a while to switch back on. This is frustrating if you are using this device for intermittent output eg; a metronome / click track for a drummer.
How to fix this:
You need a constant noise signal to keep the D/A converter from automatically muting; the signal can be inaudibly low, and will still keep the converters from muting in 'digital silence'.
Use a dither plugin on it's lowest setting on each of the ADA8000 output channels.
