Product Description

UHF AUDIO TRANSMITTER

Crystal controlled UHF audio transmitter

Extremely miniaturized crystal controlled UHF audio transmitter. Exceptional audio performance. Automatic gain control. Microphone cable length on request. A distance of approximately **0/**0 meters can be reached in open field thanks to the power output. The performance obviously depends on the environmental conditions and the sensitivity of the receiver utilized. To obtain the highest performance, it's recommended the use of the transmitters listed in the catalogue, combined with our receivers.
