Belangrijkste kenmerken

Advanced Direct Interface: Offers a transparent stereo active direct interface for various instruments.
Console-Quality Headphone Ampverliezer: Ingebouwde hoofdtelefoon amp for detailed stereo monitoring or silent practice, capable of driving high-impedance headphones.
Virtually Unclippable Design: Internal power circuit boosts standard 9V DC to 24V for massive headroom.
Flexible Pro Outputs: Supports stereo or dual mono operation with stereo XLR outputs, switchable mic/line level, and ground lift. Stereo Thru outputs include a mono sum ability.
Robuuste constructie: Housed in a durable extruded aluminum chassis for silent operation and flat frequency response.

Instellen

Follow these steps to set up your Strymon PCH:

Stroomaansluiting: 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.
Instrumentinvoer: 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-uitgangen: Connect the LEFT OUT and RIGHT OUT XLR jacks to your mixing console, audio interface, or PA system.
Hoofdtelefoonaansluiting: Plug your headphones into the PHONES 1/4" stereo jack for personal monitoring.

Bediening

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.
- Wanneer ingesteld op 'sum', the Left and Right input signals are summed to mono and sent to both THRU outputs.
- Wanneer ingesteld op '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.
- Ingesteld op 'mic' for connecting to microphone preamps or inputs expecting a mic-level signal.
- Ingesteld op '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.
- Ingesteld op 'lift' to disconnect the ground connection between the PCH and the connected device via XLR.
- Ingesteld op 'gnd' (ground) for a standard ground connection. If you experience hum, try switching to 'lift'.

Onderhoud

The Strymon PCH is designed for durability and requires minimal maintenance.

Schoonmaak: Gebruik een zachte, droge doek om de buitenkant van het apparaat schoon te maken. Vermijd schurende reinigingsmiddelen of oplosmiddelen.
Opslag: Store the PCH in a dry environment, away from extreme temperatures and direct sunlight.
Verbindingen: Controleer regelmatig of alle kabelverbindingen goed vastzitten en geen tekenen van slijtage vertonen.
Voeding: Always use a compatible 9V DC (center-negative) power supply. Using an incorrect power supply can damage the unit.

Probleemoplossing

If you encounter issues with your Strymon PCH, refer to the following common troubleshooting steps:

Probleem	Mogelijke oorzaak / oplossing
Geen geluidsuitvoer	Zorg ervoor dat de voeding correct is aangesloten en functioneert. Check all input and output cables for secure connections. Verify the PHONES volume knob is turned up. Confirm the LEVEL switch for XLR outputs is set appropriately (mic/line) for the receiving device.
Zoemend of brommend geluid	Engage the GROUND LIFT switch to 'lift'. Check for faulty cables or improper grounding in your audio chain. Ensure the power supply is not introducing noise.
Low Headphone Volume	Increase the PHONES volume knob. Ensure your headphones are properly connected and functioning. The PCH headphone amp is powerful, but extremely high-impedance headphones might require maximum volume.
Vervormd geluid	Reduce the input level from your instrument if it's excessively hot. Ensure the receiving device (mixer, interface) is not being overdriven. While the PCH is designed to be unclippable, extreme input levels can still cause issues further down the signal chain.
