FX 1-2 send controls
These controls adjust the signal level that
is sent from each channel to the two FX
mix busses. These signals will appear at
the RCA sockets on the rear of the unit.
FX1
PRE switch determines whether the
FX1 send signal is affected by the channel
fader. When pressed the signal is pre-
fader, when released post-fader.
FX1 can also be sent to the input of the
soundcard for processing or recording by
the PC (see
Soundcard Mode
for
details).
FX2
is pre-fader (this can be changed
internally - see
User Options
). FX2 can
also be selected as the audio source for
the Auto Beat detector (See
BPM
Detector
).
