Azden 51BT UHF Wireless Body-Pack Transmitter Key Features

Compact and Unobtrusive Transmitter Unit With Metal Belt Clip

The 51BT transmitter comes with a belt clip. It is small enough to also be tucked into a jacket or pants pocket.

Input Level Control

The audio input level control enables you to adjust the input level of the microphone. Turn clockwise to increase, or counter-clockwise to decrease the input level. A small screwdriver is supplied to make these adjustments. The level control is factory-preset in the center position.

Power and Standby Switches

The power ON and OFF switch enables and disables all transmitter functions while the audio switch ON and STANDBY turn the audio off and on. Switching the transmitter to STANDBY will cause the receiver to mute due to the tone squelch circuitry at the receiver. This allows the microphone to be handled with no noise.

Locking 4-Pin Hirose Connector

63 User-Selectable Frequencies

The group knob allows you to select any of seven frequency groups (numbered from 0-6). The channel knob allows you to select any of nine frequency channels (numbered from 0-8) within the selected group. This method of group/channel selection provides 63 possible choices (794-806Mhz).
