- LEVEL (XLR Outputs) Switch: Located near the XLR outputs, this switch selects the output level for the XLR connections.
- Nustatyti į 'mic' for connecting to microphone preamps or inputs expecting a mic-level signal.
- Nustatyti į 'line' for connecting to line-level inputs on mixers or audio interfaces.
- GROUND (XLR Outputs) Lift Switch: This switch helps eliminate hum and noise caused by ground loops.
- Nustatyti į 'lift' to disconnect the ground connection between the PCH and the connected device via XLR.
- Nustatyti į 'gnd' (ground) for a standard ground connection. If you experience hum, try switching to 'lift'.
