How to Use
- Connect up to 4 sources (audio/CV/gate) to the inputs.
- Select the active channel:
- Turn SEL Knob: Left = Input 1; Right = Input 4.
- Send CV to SEL Input: Add CV for voltage-controlled switching (±5V range; summed with knob position).
- Monitor Output at OUT jack—will carry only the currently selected input signal.
- Visual feedback: Green LED lights by the selected channel.
Installation Recap
- Width: 2 HP
- Depth: 42 mm
- Current: +12V: 31mA / -12V: 16mA
- Power cable red stripe = -12V (Bottom, facing the front).
Specifications
- Input Level: ±10V (all input types)
- SEL CV Range: ±5V (summed with knob)
- Noise: Low; channel switching is very fast.
Useful Patching Tips
- Use for live selection between audio/CV sources.
- Sequence the SEL CV input for step-based or random switching.
- Automate modulation or signal routing without patch changes.
