1.2 STEREO INPUT CHANNELS (ST)
1. ST1 and ST2 Inputs use standard 1/4” (6.25mm) Jack
sockets for balanced or unbalanced line level stereo sources
such as professional keyboards, drum machines and other pro
audio equipment.
2. ST2 includes USB IN 1-2 from the ZEDi USB interface.
Plugging into the jacks will override the input from USB. Make
sure nothing is plugged into the jack sockets if you want to use
the ST-2 for USB playback.
3. ST3 is USB IN 3-4 from the ZEDi USB interface.
See section 3. for more information on the ZEDi USB
interface.
4. ST1 Gain Control adjusts the input level to the ST1 channel.
There is no Gain Control for ST2.
5. HF and LF EQ are the same for as they are for M1 & M2 and
are set at the same frequencies. There is no EQ for ST2.
6. AUX send controls the amount of signal sent from the
channel to the aux buss and AUX OUT.
The signal is sourced pre-fader (MIX) so is independent of the
level being sent to the main L-R Mix. Unlike the FX bus, there is
a master level control for the Aux output.
7. FX send controls the amount of signal sent from the
channel to the FX buss and the FX OUT. The signal is post-
fader (MIX) which means it’s affected by the channel MIX
control so it stays in proportion to the signal going to the MAIN
MIX.
8. BAL adjusts the relative level between the left and right
stereo signals as they are sent to the left and right busses and
subsequently the main outputs. There is no BAL for ST2.
9. MIX rotary fader controls the amount of signal to the left
and right busses.
10. Pre-Fade Listen (PFL) switches the channel input signal to
the headphones for checking before adding it to Mix. The PFL
signal is taken after the EQ but before the MIX control.
The LR Meters display the channel input level when PFL is
activated.
