UM195B
INTRODUCTION
Thank you for selecting the Lectrosonics UM195B belt-pack transmitter. The
UM195B combines over 80 years of engineering experience with the very latest
components, in a design that addresses the most demanding professional applica-
tions.
The design of the UM195B 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 UM195B. This is certainly not the first belt-pack transmitter ever
designed, but it is definitely the most thoroughly engineered unit available.
The UM195B 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 is available on the input connector 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 or
lithium 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 UM195B transmitter is covered in this manual. Companion receivers are
covered in separate manuals. The UM195B will operate with any 190 Series
Lectrosonics receiver on a matching frequency.
