Principais características

Advanced Direct Interface: Offers a transparent stereo active direct interface for various instruments.
Console-Quality Headphone Ampmais vital: Fone de ouvido embutido 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.
Construção robusta: Housed in a durable extruded aluminum chassis for silent operation and flat frequency response.

Configurar

Follow these steps to set up your Strymon PCH:

Conexão de energia: 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.
Entrada de instrumento: 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.
Saídas XLR: Connect the LEFT OUT and RIGHT OUT XLR jacks to your mixing console, audio interface, or PA system.
Conexão de fone de ouvido: Plug your headphones into the PHONES 1/4" stereo jack for personal monitoring.

Operação

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

Manutenção

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

Limpeza: Use um pano macio e seco para limpar a parte externa da unidade. Evite produtos de limpeza abrasivos ou solventes.
Armazenar: Store the PCH in a dry environment, away from extreme temperatures and direct sunlight.
Conexões: Verifique periodicamente se todas as conexões dos cabos estão bem encaixadas e se apresentam sinais de desgaste.
Fonte de energia: Always use a compatible 9V DC (center-negative) power supply. Using an incorrect power supply can damage the unit.

Solução de problemas

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

Problema	Possível causa/solução
Sem saída de som	Certifique-se de que a fonte de alimentação esteja conectada corretamente e funcionando. 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.
Zumbido ou ruído de zumbido	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.
Som distorcido	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.
