Strymon PCH Stereo Active Direct Interface User Manual

Model: PCH

導入

The Strymon PCH is an advanced stereo active direct interface designed for musicians and audio professionals. It provides a transparent signal path for instruments like guitars, keyboards, and synthesizers, allowing direct connection to mixing consoles or recording interfaces. The PCH also features a studio-grade headphone amplifier for personal monitoring and silent practice.

This manual provides detailed instructions for setting up, operating, and maintaining your Strymon PCH to ensure optimal performance and longevity.

主な特徴

  • Advanced Direct Interface: Offers a transparent stereo active direct interface for various instruments.
  • Console-Quality Headphone Amplifier： 内蔵ヘッドホン 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.
  • 頑丈な構造: Housed in a durable extruded aluminum chassis for silent operation and flat frequency response.

設定

Follow these steps to set up your Strymon PCH:

  1. 電源接続: 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.
  2. 機器入力: Connect your instrument (guitar, synth, keyboard, etc.) to the IN (Left/Right) 1/4" input jacks. For mono instruments, use the Left IN jack.
  3. 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.
  4. XLR出力: Connect the LEFT OUT and RIGHT OUT XLR jacks to your mixing console, audio interface, or PA system.
  5. ヘッドホン接続: Plug your headphones into the PHONES 1/4" stereo jack for personal monitoring.

手術

Understanding the controls of your PCH is essential for optimal sound routing and monitoring.

  • PHONES ボリュームノブ: 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.
    • に設定すると 'sum', the Left and Right input signals are summed to mono and sent to both THRU outputs.
    • に設定すると '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.
    • 設定 'mic' for connecting to microphone preamps or inputs expecting a mic-level signal.
    • 設定 '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.
    • 設定 'lift' to disconnect the ground connection between the PCH and the connected device via XLR.
    • 設定 'gnd' (ground) for a standard ground connection. If you experience hum, try switching to 'lift'.

メンテナンス

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

  • クリーニング： 本体の外装を清掃する際は、柔らかく乾いた布をご使用ください。研磨剤入りの洗剤や溶剤は使用しないでください。
  • ストレージ： Store the PCH in a dry environment, away from extreme temperatures and direct sunlight.
  • 接続: すべてのケーブル接続が確実に固定され、摩耗の兆候がないか定期的に確認してください。
  • 電源： Always use a compatible 9V DC (center-negative) power supply. Using an incorrect power supply can damage the unit.

トラブルシューティング

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

問題考えられる原因 / 解決策
音が出ない
  • 電源が正しく接続され、機能していることを確認します。
  • すべての入力ケーブルと出力ケーブルが確実に接続されているかどうかを確認します。
  • Verify the PHONES volume knob is turned up.
  • Confirm the LEVEL switch for XLR outputs is set appropriately (mic/line) for the receiving device.
ハム音またはブザー音
  • 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.
歪んだ音
  • 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.
