Overview:

The Lectrosonics UM100 multi-frequency, belt-pack transmitter. The UM100 combines over 80 years of engineering experience with the very latest components, in a design that addresses the most demanding professional applications.

The UM100 is a rugged, machined aluminum package with a removable, spring
loaded belt clip. The input section provides a correct input tap for virtually any microphone or line level audio source. 5 Volts of bias voltage is available to power electric mics with either positive or negative bias. Level indicating LEDs are provided on the control panel to make level settings quick and accurate, without having to view the receiver. The battery compartment accepts any 9 Volt alkaline battery and makes a positive connection via self-adjusting contacts. The antenna is a fixed 1/4 wavelength flexible bronze cable.
