Frequency Agile UHF Belt-Pack Transmitter
Rio Rancho, NM – USA
INTRODUCTION
Thank you for selecting the Lectrosonics UM200C frequency agile, belt-pack trans-
mitter. The UM200C 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 UM200C 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 develop-
ment of the operational features offered on the UM200C. 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 UM200C 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 detach-
able, locking 1/4 wavelength flexible bronze cable that connects to a 50 Ohm SMA
port on the transmitter.
Only the UM200C transmitter is covered in this manual. Companion receivers are
covered in separate manuals. The UM200C will operate with any 200 Series Lec-
trosonics receiver in the same frequency group.
