4MS Shifting Inverting Signal Mingler (SISM)

4MS

Basic features

Four independent voltage processor channels, with four mix/mingle outputs
Each channel has:
- Input jack
- Scale knob (from inverted unity, to zero, to unity
- Shift knob (adds/subtracts DC offset from -9V to +9V)
- Output jack
- Red and blue LEDs to indicate + or - voltage, as well as intensity
MIX jack outputs sum of all channels
MIX SWitch jack outputs sum of all channels with nothing plugged into their output jack
+ SLICE jack outputs positive portion of mix (voltages greater than 0V)
- SLICE jack outputs negative portion of mix (voltages less than 0V)
Red and blue LEDs on all four mix/mingle jacks display what the signal is doing
12HP, 22mm depth
+12V rail: 51mA max
-12V rail: 51mA max

Advanced features

Channels 1+2 and 3+4 are normaled together on the input, so plugging into Channel 1 (or 3) will split the signal: A jumper can disable this normalization
Scale knob has three ranges that are selectable with jumpers:
- Bi-polar: -1x to +1x (inverting unity to unity) --default
- Uni-polar: 0 to +1x (level fader)
- Boost: 0 to 2x (twice the voltage gain)
Input Header (2x4) for connecting the output of a QCD or QPLFO to the SISM's inputs. Plugging into the input jacks overrides the signal on the header
Output Header (2x4) for connecting to the input of a VCA Matrix or other compatible module
PAD breakout header (2x4) for connecting to a breakout module that applies a pre-set pad (attenuation) to each channel.
