Mutable Instruments

Capabilities 3

Attenuverterattenuverter
Three independent channels each selectable as attenuator (gain 0 to 1) or attenuverter (gain -1 to +1).603
Mixermixer
Cascading outputs allow up to 3 channels to be summed passively without extra cables by leaving earlier outputs unpatched.603
Offset Generatoroffset-generator
With IN unpatched and jumper set to +5V or +10V, the Gain knob generates an adjustable constant voltage offset at the output.603

Jacks 6 — 3 in / 3 out

NameSignalVoltageDescription
Inputs (3)
CH1 INmixed—Signal input for channel 1. DC-coupled. Normalled to +5V, +10V, or 0V depending on rear jumper setting when unpatched.603
CH2 INmixed—Signal input for channel 2. DC-coupled. Normalled to +5V, +10V, or 0V depending on rear jumper setting when unpatched.603
CH3 INmixed—Signal input for channel 3. DC-coupled. Normalled to +5V, +10V, or 0V depending on rear jumper setting when unpatched.603
Outputs (3)
CH1 OUTmixed—Signal output for channel 1. When unpatched, channel 1's signal cascades into channel 2's input sum node.603
CH2 OUTmixed—Signal output for channel 2. When outputs 1 and 2 are unpatched, output 3 contains the sum of all three channels.603
CH3 OUTmixed—Signal output for channel 3. Final mix output when channels 1 and/or 2 outputs are unpatched.603

Parameters 9

NameTypeRangeBehavior
CH1 Function Selectorswitch—Selects attenuator mode (lower position, gain 0 to 1) or attenuverter mode (upper position, gain -1 to +1) for channel 1.603
CH1 Gainknob—In attenuator mode, gain ranges from 0 (fully CCW, muted) to 1 (fully CW, unity). In attenuverter mode, gain ranges from -1 (fully CCW, inverted) to +1 (fully CW, unity), with 0 (muted) at 12 o'clock.603
Zones
Attenuverter (inverted)
Attenuverter (non-inverted)
  • Attenuverter (inverted) -100–0%Gain from -1 to 0; signal is inverted and progressively less so toward 12 o'clock where it is muted.603
  • Attenuverter (non-inverted) 0–100%Gain from 0 to +1; signal progresses from muted at 12 o'clock to unity at fully CW.603
CH1 Normalling Jumperjumper—Rear-panel jumper that selects the normalled voltage for CH1 IN when unpatched: +5V, +10V, or 0V (jumper removed).603
CH2 Function Selectorswitch—Selects attenuator mode (lower position, gain 0 to 1) or attenuverter mode (upper position, gain -1 to +1) for channel 2.603
CH2 Gainknob—In attenuator mode, gain ranges from 0 (fully CCW, muted) to 1 (fully CW, unity). In attenuverter mode, gain ranges from -1 (fully CCW, inverted) to +1 (fully CW, unity), with 0 (muted) at 12 o'clock.603
CH2 Normalling Jumperjumper—Rear-panel jumper that selects the normalled voltage for CH2 IN when unpatched: +5V, +10V, or 0V (jumper removed).603
CH3 Function Selectorswitch—Selects attenuator mode (lower position, gain 0 to 1) or attenuverter mode (upper position, gain -1 to +1) for channel 3.603
CH3 Gainknob—In attenuator mode, gain ranges from 0 (fully CCW, muted) to 1 (fully CW, unity). In attenuverter mode, gain ranges from -1 (fully CCW, inverted) to +1 (fully CW, unity), with 0 (muted) at 12 o'clock.603
CH3 Normalling Jumperjumper—Rear-panel jumper that selects the normalled voltage for CH3 IN when unpatched: +5V, +10V, or 0V (jumper removed).603
