Introduction / System Features
Congratulations on purchasing the Samson UM1 micro diversity receiver—part of our
renowned UHF Series One Wireless System! Although this product is designed for easy
operation, we suggest you first take some time to go through these pages so you can fully
understand how we’ve implemented a number of unique features.
Every wireless system consists of at least two components—a transmitter and a receiver,
both of which must be tuned to the same channel (that is, the same radio frequency) in
order to operate correctly.* The Samson UM1 system you have purchased operates in the
801 - 805 MHz frequency range and contains a UM1 micro diversity receiver and one of
three Series One transmitters: a UT1L belt-pack transmitter (for lavalier microphone or
headset applications); a UT1G belt-pack transmitter (for instrument applications); or a
UH1 hand-held microphone transmitter (available in a wide variety of popular capsules).
The UM1 system is specially designed to enable the production of professional audio
tracks to accompany your video shoot or live broadcast. The use of a handheld mic
transmitter or lavalier microphone connected to a beltpack transmitter effectively isolates
the performer from unwanted ambient sounds such as video camera motor noise or room
sounds made by the camera operator or video crew. Because the UM1 receiver is
extremely small and lightweight, it can be attached easily to any video camera using the
supplied strip of velcro, and can even be powered directly by the camera’s own 12-volt
power supply, if available.
In this manual, you’ll find a more detailed description of the features of the UM1 system, as
well as a guided tour through all components, step-by-step instructions for setting up your
system, wiring diagrams and tables, and full specifications. If your UM1 system was
purchased in the United States, you’ll also find a warranty card enclosed—don’t forget to
fill it out and mail it! This will enable you to receive online technical support and will allow
us to send you updated information about this and other Samson products in the future.
If your UM1 system was purchased outside of the U. S., contact your local distributor for
warranty details.
SPECIAL NOTE for U.S. purchasers: Should your UM1 system ever require servicing, a
Return Authorization number (RA) is necessary. Without this number, the unit will not be
accepted. If your UM1 system was purchased in the United States, please call Samson at
1-800-372-6766 for a Return Authorization number prior to shipping your unit. If possible,
return the unit in its original carton and packing materials. If your UM1 system was
purchased outside of the U. S., contact your local distributor for servicing information.
* Your receiver and transmitter have been factory preset to utilize the same channel.
A listing of the six available channels and their corresponding UHF frequencies can be
found on page 4 of this manual.

Designed for use in both live sound and sound contracting applications, the Samson UM1
system provides a high performance, cost effective solution, utilizing state-of-the-art
technology in wireless communications. Main features include:
