Follow these steps to set up your Strymon PCH:

توصيل الطاقة: 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.
مدخلات الآلة: 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.
مخرجات XLR: Connect the LEFT OUT and RIGHT OUT XLR jacks to your mixing console, audio interface, or PA system.
اتصال سماعة الرأس: Plug your headphones into the PHONES 1/4" stereo jack for personal monitoring.

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

الاتصالات: قم بفحص جميع توصيلات الكابلات بشكل دوري للتأكد من تثبيتها بإحكام وعدم وجود علامات تآكل.
مزود الطاقة: Always use a compatible 9V DC (center-negative) power supply. Using an incorrect power supply can damage the unit.

استكشاف الأخطاء وإصلاحها

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

مشكلة	السبب المحتمل / الحل
لا يوجد مخرج صوت	تأكد من توصيل مصدر الطاقة بشكل صحيح وعمله بشكل سليم. 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.
صوت طنين أو أزيز	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.
صوت مشوه	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.
