321
A three-section multi-purpose utility module for high-quality audio and CV processing, capable of scaling, inverting, and adding positive or negative offsets to signals, with two summing outputs and DC-coupled circuitry.884
Capabilities 4
- Attenuatorattenuator
- Each of the three sections includes a DC-coupled amplifier for attenuation or amplification of audio and CV up to 6dB.884
- Mixermixer
- Two summing bus outputs with selectable -6dB attenuation; one bus sums all sections, the other sums only sections not using their individual outputs.884
- Offsetoffset
- Each section has an offset control that adds or subtracts DC offset; doubles as a DC voltage source when no signal is patched.884
- Signal Invertersignal-inverter
- Each section has a polarity/phase inversion switch, enabling inversion of CV or audio phase.884
Jacks 8 (3 in / 5 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (3) | |||
| CH1 IN | mixed | — | 884 |
| CH2 IN | mixed | — | 884 |
| CH3 IN | mixed | — | 884 |
| Outputs (5) | |||
| CH1 OUT | mixed | — | 884 |

| CH3 OUT | mixed | — | 884 |
| Sum All OUT | mixed | — | Sums all three sections including offsets, regardless of whether individual section outputs are patched.884 |
| Unpatched Sum OUT | mixed | — | Sums only sections whose individual output jack is not patched; patching a dummy cable to a section output removes it from this sum.884 |
Parameters 14
| Name | Type | Range | Behavior |
|---|---|---|---|
| CH1 Invert Switch | switch | — | Flips the phase of an audio signal or inverts the polarity of a CV. Combined with the level attenuator, allows precise zeroing of the channel output.884 |
| CH1 Level | menu_setting | — | Attenuates or amplifies the channel signal; DC-coupled so it works on both audio and CV. Gain up to 6dB (doubling the signal level).884 |
| CH1 Offset | knob | — | Adds or subtracts a DC offset to the section's signal; can convert unipolar to bipolar signals. When no input is patched, outputs a positive or negative steady DC voltage.884 |
| CH1 Offset Enable Switch | switch | — | Disables the offset section entirely for more transparent signal processing.884 |
| CH2 Invert Switch | switch | — | Flips the phase of an audio signal or inverts the polarity of a CV. Combined with the level attenuator, allows precise zeroing of the channel output.884 |
| CH2 Level | menu_setting | — | Attenuates or amplifies the channel signal; DC-coupled so it works on both audio and CV. Gain up to 6dB (doubling the signal level).884 |
| CH2 Offset | knob | — | Adds or subtracts a DC offset to the section's signal; can convert unipolar to bipolar signals. When no input is patched, outputs a positive or negative steady DC voltage.884 |
| CH2 Offset Enable Switch | switch | — | Disables the offset section entirely for more transparent signal processing.884 |
| CH3 Invert Switch | switch | — | Flips the phase of an audio signal or inverts the polarity of a CV. Combined with the level attenuator, allows precise zeroing of the channel output.884 |
| CH3 Level | menu_setting | — | Attenuates or amplifies the channel signal; DC-coupled so it works on both audio and CV. Gain up to 6dB (doubling the signal level).884 |
| CH3 Offset | knob | — | Adds or subtracts a DC offset to the section's signal; can convert unipolar to bipolar signals. When no input is patched, outputs a positive or negative steady DC voltage.884 |
| CH3 Offset Enable Switch | switch | — | Disables the offset section entirely for more transparent signal processing.884 |
| Sum All -6dB Switch | switch | — | Halves the output amplitude of the sum output to manage headroom when the mix is too loud.884 |
| Unpatched Sum -6dB Switch | switch | — | Halves the output amplitude of the unpatched-sections sum output to manage headroom when the mix is too loud.884 |
