INTRODUCTION
Thank you for selecting the Lectrosonics UM195 belt-pack transmitter. The UM195 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 UM195 was the direct result of numerous conversations with users, staging and touring
companies 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 UM195. This is certainly not the first belt-
pack transmitter ever designed, but it is definitely the most thoroughly engineered unit available.
The UM195 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 detachable, locking 1/4 wavelength flexible wire that connects to a 50 Ohm port on the transmitter.
Only the UM195 transmitter is covered in this manual. Companion receivers are covered in separate manuals.
The UM195 will operate with any 195 Series Lectrosonics receiver on the same frequency.
