Konfigurazioa
Follow these steps to set up your Strymon PCH:
- Potentzia-konexioa: Connect a standard 9V DC power supply (center-negative) to the 9VDC input jack on the PCH. The unit will internally boost this to 24V for optimal performance.
- Instrumentuaren sarrera: Connect your instrument (guitar, synth, keyboard, etc.) to the IN (Left/Right) 1/4" input jacks. For mono instruments, use the Left IN jack.
- Thru Outputs: Use the THRU (Left/Right) 1/4" jacks to send the input signal to other devices, such as an amplifier or pedalboard. The THRU outputs can be summed to mono using the 'sum stereo' switch if desired.
- XLR irteerak: Connect the LEFT OUT and RIGHT OUT XLR jacks to your mixing console, audio interface, or PA system.
- Aurikularretarako konexioa: Plug your headphones into the PHONES 1/4" stereo jack for personal monitoring.

Funtzionamendua
Understanding the controls of your PCH is essential for optimal sound routing and monitoring.
- PHONES Volume Knob: Adjusts the output level for the connected headphones. Rotate clockwise to increase volume, counter-clockwise to decrease.
- SUM (THRU) Switch: This switch affects the THRU outputs.
- Ezarritakoan 'sum', the Left and Right input signals are summed to mono and sent to both THRU outputs.
- Ezarritakoan 'stereo', the Left input goes to the Left THRU, and the Right input goes to the Right THRU.
- LEVEL (XLR Outputs) Switch: Located near the XLR outputs, this switch selects the output level for the XLR connections.
- Ezarri gisa 'mic' for connecting to microphone preamps or inputs expecting a mic-level signal.
- Ezarri gisa '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.
- Ezarri gisa 'lift' to disconnect the ground connection between the PCH and the connected device via XLR.
- Ezarri gisa 'gnd' (ground) for a standard ground connection. If you experience hum, try switching to 'lift'.
