How to use

Install the mounting kit as required for your setup, connect the receiver to your sound system via the XLR-3 output, and attach external antennas to the receiver connectors for best reception. Power the transmitter with batteries or a charged accumulator, switch on both transmitter and receiver, and tune the receiver to match the transmitter’s channel within the 470.2–526 MHz range. Position the microphone with its cardioid pickup facing the sound source to minimise off-axis noise. Use the receiver display to monitor signal and audio levels during operation.

Recommendations

Do not open the unit housing. For reliable wireless performance, place receiver antennas clear of large metal surfaces and maintain line of sight where possible. Replace or recharge batteries before long sessions and avoid operating the system outside the specified temperature and humidity ranges.
