Assignable Channel Strip; Input Section - SoundCraft Si Performer User Manual

Assignable Channel Strip (ACS)
The Assignable Channel Strip
(ACS) follows the currently
SELected channel or bus and
provides almost all of the
controls relating to the selected
channel or bus; it is broken
down in to small colour coded
sections making it easy to
identify control groups and
functions at a glance.
Unlike any other console in this class, there is a dedicated control for each
function therefore no 'overlaying' of controls is needed and each control has a
dedicated label and scale just as you would have found on an analogue mixer
Any encoders or functions that are not available/appropriate for a given mode will be un-lit
and have no function. Although the control surface has values marked against the encoders
the absolute value of any encoder will be shown on the touch screen provided by the Function
Focus feature.
The GAIN/TRIM encoder on the ACS functions as GAIN control when controlling a mic
*1
amp and TRIM for a LINE source whenever the ACS is selected to an input

1. Meter: indicates the level in the channel or bus; if the source is
MONO only the left meter will indicate signal, if the source is stereo
the stereo indicator will light red and the meter will operate in stereo.
2. 48v key: toggles 48v Phantom Power ON/OFF if the SELected
channel is connected to a MIC input; illuminates when 48v is ON.
Pressing and holding the key will activate INTERROGATE mode for
this function.
3. PHASE key: toggles the phase of the channel or bus, illuminates
when PHASE is reversed. Pressing and holding the key will activate
INTERROGATE mode for this function. Phase reverse is not available
for matrix bus outputs.
4. GAIN: indicates and adjusts one of two parameters depending
upon the input source type of the selected channel:
Mic gain — if selected to an input patched to a mic input
Line trim — if selected to an input patched to a line input, AES
input or similar. When operating in line trim mode the centre red
led will light when the trim gain is 0dB.
5. HPF (High Pass Filter): indicates and adjusts the frequency of the
HPF (not L&R, mono or matrix). Has no effect until the 'HPF' filter
is switched IN.
6. HPF key: toggles the High Pass Filter as IN or OUT; illuminates when
HPF is IN. Press the key to toggle the filter IN/OUT. Pressing and
holding the key will activate INTERROGATE mode for this function.
