Operating Instructions

Basic Operation

• Monitoring Audio: Once connected and powered on, the audio signal from your source will be transmitted wirelessly to the bodypack receivers. Listen through your connected earphones.
• Volume Control: Use the volume adjustment knob on each bodypack receiver to control the individual monitoring volume. The transmitter's earphone volume control affects only the direct monitoring output from the transmitter itself.
• Signal Range: The system operates effectively within a range of 164 to 262 feet (50-80 meters) in open, line-of-sight conditions. Obstacles like walls or large metal objects can reduce this range.

• High Fidelity Sound: Advanced circuit design and upgraded chips improve the signal-to-noise ratio, delivering clear sound and high fidelity without noticeable latency.
• Mono Output: While the transmitter supports stereo input, the bodypack receivers provide a mono output for monitoring.
