Setup

Proper setup ensures the JHS 3 Series Compressor functions as intended and integrates seamlessly into your signal chain.

Power Requirements

• The JHS 3 Series Compressor requires a 9V DC power supply.
• Ensure the power supply has a negative center pin.
• The pedal consumes approximately 8mA of current.
• Using an incorrect power supply type or voltage may damage the unit and void the warranty.

Connecting the Pedal

1. Connect your instrument (e.g., guitar) to the INPUT jack on the right side of the pedal using a standard 1/4-inch (6.35mm) instrument cable.
2. Connect the OUTPUT jack on the left side of the pedal to your amplifier or the next pedal in your signal chain using another standard 1/4-inch (6.35mm) instrument cable.
3. Connect the 9V DC negative center power supply to the power input jack located at the top of the pedal.
4. Once powered, the LED indicator will illuminate when the pedal is active.

Operating the JHS 3 Series Compressor

The JHS 3 Series Compressor features intuitive controls for shaping your sound. Experiment with each knob and switch to discover the full range of its capabilities.

Controls

• Volume Knob:

  This knob controls the overall output level of the pedal. It can be used to set the volume at unity gain (matching the bypassed signal level) or to provide a boost to your signal.

• Attack Knob:

  The Attack knob adjusts how quickly the compressor reacts to the initial transient of your notes.

  • Turning the Attack knob clockwise (higher setting) results in a slower attack, allowing more of the initial pick attack or note transient to pass through before compression engages. This can create a punchier, more dynamic sound.
  • Turning the Attack knob counter-clockwise (lower setting) results in a faster attack, engaging compression more quickly and smoothing out the initial transient. This can lead to a more even, sustained sound.

• Sustain Knob:

  The Sustain knob controls the duration of the compression effect, influencing how long notes ring out.

  • Turning the Sustain knob clockwise increases the amount of sustain, making notes ring out longer and creating a more compressed sound.
  • Turning the Sustain knob counter-clockwise reduces sustain, resulting in a more natural decay and less compression.
• Bright Toggle Switch:

  This toggle switch engages a brighter EQ setting.

  • When engaged (up position), the Bright toggle adds high-end frequencies to your signal, helping your tone cut through a mix or preventing it from sounding dull, especially with heavy compression.
  • When disengaged (down position), the pedal operates with its standard EQ response.

Basic Operation

1. Ensure all connections are secure and the pedal is powered.
2. Press the footswitch to activate the compressor. The LED will illuminate.
3. Start with the Volume knob at unity gain (usually around 12 o'clock), Attack at 12 o'clock, and Sustain at 9 o'clock.
4. Adjust the Sustain knob clockwise to increase the compression and sustain.
5. Adjust the Attack knob to fine-tune the initial transient response. Slower attack for punch, faster attack for smoothness.
6. Use the Bright toggle to add clarity if your tone sounds too dark or gets lost in the mix.
7. Finally, adjust the Volume knob to achieve the desired output level.

Maintenance

To ensure the longevity and optimal performance of your JHS 3 Series Compressor, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the pedal's exterior. Avoid abrasive cleaners, solvents, or excessive moisture, as these can damage the finish or internal components.
• Storage: When not in use for extended periods, store the pedal in a cool, dry place away from direct sunlight and extreme temperatures. Disconnect the power supply and all cables.
• Connections: Periodically check all cable connections (input, output, power) for wear or damage. Ensure they are securely plugged in during use.
• Power Supply: Always use a compatible 9V DC negative center power supply. Using an incorrect power supply can cause irreversible damage.
• Avoid Physical Shock: Protect the pedal from drops or impacts, which can damage internal circuitry or external components.
