Lectrosonics UM200 - Manual (Page 3)

INTRODUCTION
Thank you for selecting the Lectrosonics UM200 frequency agile, belt-pack transmitter. The UM200 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 UM200 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 UM200. 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 UM200 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 UM200 transmitter is covered in this manual. Companion receivers are covered in separate manuals.
The UM200 will operate with any 200 Series Lectrosonics receiver in the same frequency group.
