Multi-frequency UHF Belt-Pack Transmitter

INTRODUCTION

Thank you for selecting the Lectrosonics UM100 multi-frequency, belt-pack transmit-

ter. 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 design of the UM100 was the direct result of numerous conversations with users

and dealers across the US. The specific concerns and needs brought up in these

conversations led directly to the development of the operational features offered on

the UM100. Two hundred fifty six frequencies are user selectable in 100kHz steps to

alleviate interference problems in travelling venues, and the low frequency roll-off is

user adjustable to adapt to varying acoustic environments and preferences.

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

electret 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.

Only the UM100 transmitter is covered in this manual. Companion receivers are

covered in separate manuals. The UM100 will operate with any 100 Series Lec-

trosonics receiver in the same frequency group.
