JHS Pedals Mini A/B Box Instruction Manual

Introduction

The JHS Pedals Mini A/B Box is a compact and versatile signal routing device designed for guitarists and other musicians. It allows for seamless switching between two different signal paths, offering a range of applications on stage, in the studio, or during practice. This manual provides essential information for the proper setup, operation, and maintenance of your Mini A/B Box.

Features

• Simple footswitch design for selecting between two 1/4-inch jacks.
• Enables instant swapping between two instruments.
• Ideal for switching tones on dual amplifier rigs.
• Allows isolation of a tuner from the signal chain for silent onstage tuning.
• Can function as a convenient mute by leaving one output unplugged.
• Compact size optimizes pedalboard space.

Package Contents

• 1x JHS Pedals Mini A/B Box
• 1x 9V DC power supply (for LED indicator only)

Controls and Connections

This image displays the JHS Pedals Mini A/B Box. The top features a red LED indicator. The center shows the 'A/B' logo. At the bottom is the footswitch. On the sides, there are 1/4-inch audio jacks for signal input and output.

• 1/4-inch Jacks: The pedal features three 1/4-inch audio jacks. Two are located on one side (typically the left) and one on the opposite side (typically the right). These jacks serve as inputs and outputs depending on your desired signal flow.
• Footswitch: The large button on the front of the pedal is the footswitch, used to toggle between the two active signal paths.
• LED Indicator: A small LED light near the top of the pedal indicates which signal path is currently active. It typically illuminates in different colors (e.g., blue or red) to distinguish between the 'A' and 'B' paths.
• 9V DC Power Input: A standard 9V DC power input jack is located at the top of the pedal. This power is solely for illuminating the LED indicator; the audio signal path is passive.

Setup

1. Power Connection: Connect a standard 9V DC power supply (center negative) to the power input jack. This powers the LED indicator. The pedal will function passively for audio switching even without power, but the LED will not light up.
2. Signal Path A (Input/Output): Connect your first instrument, amplifier, or pedal chain to one of the 1/4-inch jacks on the left side.
3. Signal Path B (Input/Output): Connect your second instrument, amplifier, or pedal chain to the other 1/4-inch jack on the left side.
4. Common Output/Input: Connect your amplifier (if switching instruments) or your instrument (if switching amplifiers) to the 1/4-inch jack on the right side.
5. Ensure all cables are securely connected.

Operating Instructions

Once connected, operate the JHS Pedals Mini A/B Box as follows:

• Switching Paths: Press the footswitch to toggle between the two connected signal paths (A and B).
• LED Indication: The LED indicator will change color (e.g., blue for path A, red for path B) to visually confirm which path is currently active.
• Directional Flexibility: The Mini A/B Box is bidirectional. It can be used as 2 inputs to 1 output (e.g., two guitars to one amp) or 1 input to 2 outputs (e.g., one guitar to two amps).

Applications

The versatility of the Mini A/B Box allows for several practical applications:

• Instrument Switching: Quickly switch between two different guitars or other instruments connected to a single amplifier or pedalboard.
• Amplifier Switching: Route a single instrument's signal to two different amplifiers, allowing for instant tone changes or stereo setups.
• Tuner Isolation: Connect your tuner to one of the outputs. When that output is selected, your main signal path is muted, allowing for silent tuning on stage.
• Signal Mute: By leaving one of the outputs unplugged, you can use the pedal as a mute switch for your signal.

Maintenance

To ensure the longevity and optimal performance of your JHS Pedals Mini A/B Box, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the pedal. Avoid abrasive cleaners or solvents.
• Environment: Protect the pedal from extreme temperatures, direct sunlight, high humidity, and moisture.
• Storage: When not in use for extended periods, store the pedal in a dry, cool place.
• Servicing: Do not attempt to open the pedal enclosure or perform any internal repairs. This may void your warranty and could damage the unit. Refer all servicing to qualified personnel.

Troubleshooting

• No Sound:
  • Check all cable connections to ensure they are secure and correctly plugged into the appropriate jacks.
  • Verify that your instrument, amplifier, and other pedals in the chain are functioning correctly.
  • Ensure the correct signal path is selected by observing the LED indicator.
• Noise or Hum:
  • Ensure all power supplies are properly grounded and free from interference.
  • Try using different, high-quality instrument cables.
  • Test the pedal in a different electrical outlet or location to rule out environmental interference.
• LED Not Lighting Up:
  • Confirm that a 9V DC power supply is connected and functioning. The LED requires power to operate, even though the audio path is passive.
• Audible Click When Switching:
  • A slight mechanical click sound when pressing the footswitch is normal for passive, mechanical A/B boxes and does not indicate a malfunction.
