How to use

Place the receiver in a location with clear line-of-sight to the transmitting microphone or transmitter unit when possible, and connect it to the mixing console or amplifier via the appropriate audio outputs. Power both transmitter and receiver according to the manufacturer's instructions and select the matching frequency range (823–832 MHz or 863–865 MHz) on both units. Perform a brief channel and level check before use to confirm a clean, noise-free signal and adjust gain to prevent clipping. Keep spare batteries or a charged power source available for uninterrupted operation.

Usage recommendations

For reliable performance, use the set within its specified frequency ranges and maintain reasonable separation from other wireless systems operating on adjacent bands. Perform a frequency scan or coordination in environments with multiple wireless devices to avoid congestion. Position the receiver away from large metal obstructions and Wi‑Fi routers, and verify battery levels prior to events.
