The AudioDock
The AudioDock connects to the E-MU 1010  PCI card via the EDI cable. 
fThe AudioDock is 
completely “hot 
pluggable”— It’s OK to 
plug or unplug the 
AudioDock while the 
computer is turned on.

 It’s a good idea to 
mute AudioDock inputs 3 
in the PatchMix DSP 
mixer when nothing is 
plugged in, since the 
turntable preamp has a 
very high gain (60dB) 
and could contribute 
extra noise to your mix/...

The Session
The current state of the PatchMix DSP mixer (fader settings, effects routings…every-
thing!) can be saved as a Session. Whenever you create or modify a mixer setup, all you 
have to do is Save it to be able to recall it at a later time.
Before you begin using PatchMix DSP, you need to set it up to be compatible with the 
other software applications you may be running. The most important consideration is 
your system sample rate....
