Page 15: Introduction
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. -
Page 16: General Technical Description
GENERAL TECHNICAL DESCRIPTION The UM100 transmitters are comprised of a number of functional sub-systems as shown in the block diagram below. GENERAL The 100 system uses 20 kHz wide deviation for a high signal to noise ratio. The transmitter circuits are all regulated to allow full output power from the beginning (9 Volts) to the end (6.5 Volts) of battery life. - Page 17 Multi-frequency UHF Belt-Pack Transmitter PRE-EMPHASIS/DE-EMPHASIS The signal to noise ratio of the 100 system is extended by using pre-emphasis (HF boost) in the transmitter and de- emphasis (HF roll off) in the receiver. Pre-emphasis and de-emphasis in an FM radio system usually provides about a 10 dB improvement in the signal to noise ratio of the system, but the high frequency boost in the transmitter must be removed in a purely complimentary manner or else the frequency response of the original audio signal will be altered.

Page 20: Battery Installation
BATTERY INSTALLATION The transmitter is powered by a standard alkaline or lithium 9 Volt battery. It is important that you use ONLY an ALKALINE or LITHIUM battery for longest life. Standard zinc-carbon batteries marked “heavy-duty” or “long- lasting” are not adequate. Ni-cad rechargeable batteries will only provide 1.5 hours of operation, or less, and will run down quite abruptly. -
Page 21: Operating Instructions
To gain access to these switches, slide the access door sideways with a fingernail. Note: With the UCR100 receiver, these switches also appear on the side panel of the receiver. You should always set the transmitter switches to match the receiver switch settings. -

MICROPHONE CORD TERMINATION TA5F Connector Assembly VIEW FROM SOLDER SIDE OF PINS 0.15" Heatshrink Tubing 0.3" Mic Cord Stripping Instructions Caution! Do not allow the shield wire to touch any metal part of the connector shell. The shield wire is the antenna on VHF models and poor operating range will result. -
Page 23: 5-Pin Input Jack Wiring
Low impedance microphone level input for dynamic microphones. Also accepts hand-held electret micro- phones provided the microphone has its own built-in battery. PIN 4 1K Ohm source load for non-Lectrosonics electret microphones. Use in conjunction with other pins to provide attenuation of high level input signals. PIN 5 High impedance, line level input for tape decks, mixer outputs, musical instruments, etc. - Page 24 Leaded capacitors: P/N 15117 Leadless capacitors: P/N SCC330P All Lectrosonics lavalier mics are already bypassed and do not need any additional capacitors installed for proper operation. BODY GROUND Caution - When wiring the connector, do not use the connector body for any electrical connections. A common mistake is to use the connector body as an audio ground.
