How to use

Connect audio sources to the transmitter using the XLR combo inputs or other available inputs, set the transmitter and receiver to a matching frequency within 476–500 MHz, and attach the in-ear headphones to the receiver's 3.5 mm output. Power the receiver with two batteries and place the bodypack on the performer. Adjust the transmitter and receiver levels and use the limiter feature to avoid excessive peaks. Place the transmitter on stage or a stable surface and use the 6.35 mm output if monitoring from a console or headphone amplifier is required.

Recommendations

Avoid contact with water and operate the system within the specified 0–40 °C temperature range. For best results, select a clear UHF frequency and check levels during a soundcheck to minimise interference and ensure comfortable monitoring volume.
