User Manual for Chord VGW1 VHF Guitar Wireless System

Quick Start Guide

The Chord VGW1 is a professional VHF wireless system designed for guitars. To begin, ensure you have all components, install the battery in the transmitter, connect the receiver to power and your amplifier, and adjust the volume levels.

Components

• VHF wireless receiver
• Mains power adapter
• 6.3mm to 3.5mm instrument jack lead
• 6.3mm mono jack lead
• 9V battery, PP3

Operation

Transmitter Setup: Slide the front half of the beltpack upwards to reveal the battery compartment. Insert the supplied 9V battery, ensuring correct polarity (+ and -), and slide the case back together.

Receiver Setup: Position the receiver within the best available line of sight to the transmitter. Connect the DC jack of the supplied power adapter to the receiver and the plug-top to the mains outlet. Extend both antennas fully upwards and outwards slightly. Switch the power on and turn the output level down on the receiver.

Connecting to Audio: Connect the jack or XLR lead to the receiver’s audio output connector. Turn down the volume of the guitar amplifier or effect unit, then connect the lead to the amplifier. Move the slide switch on the beltpack transmitter to the first notch (MUTE) to check the LED, then move to the second notch (ON). Gradually increase the output level on the receiver and the volume on the guitar amplifier until the sound is audible.

Safety and Placement

• Do not expose components to rain or moisture.
• Keep components out of direct sunlight and away from heat sources.
• Do not place heavy objects on top of the receiver or transmitter.
• If rack-mounting, secure the receiver to a 1U rack tray.
• Use alkaline or NiMH batteries and remove them if the unit is unused for long periods.

Cleaning

Use a soft cloth with a neutral detergent to clean the body of the beltpack transmitter and receiver. Lightly damp sterile wipes may be used on the beltpack for hygiene. Do not use solvents to clean the components.

Troubleshooting

If you encounter issues, check the following:

• Power LED does not light: Ensure the power adapter is connected to the mains and working properly, and the receiver is switched on.
• No sound from mic: Make sure the receiver is connected to the mixer/amplifier and that channel volumes are turned up.
• Distorted sound: Turn down the volume on the receiver, reduce the gain on the bodypack transmitter, or reduce the gain on the mixer/amplifier.
• Low output: Turn up the volume on the receiver, increase the gain on the bodypack transmitter, or increase the gain of the mixer/amplifier input.
