Introduction / System Features

Congratulations on purchasing the Samson VM1 micro diversity receiver—part of our
renowned VHF TD Series 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 VM1 system you have purchased operates in
the 173.8 - 213.2 MHz frequency range and contains a VM1 micro diversity receiver and
one of our VHF TD Series transmitters: either a VT3L belt-pack transmitter (for lavalier
microphone or headset applications) or a VH3 hand-held microphone transmitter
(available in a wide variety of popular capsules).

The VM1 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 VM1 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 VM1 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 VM1 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 VM1 system was purchased outside of the U. S., contact your local distributor for
warranty details.

SPECIAL NOTE for U.S. purchasers: Should your VM1 system ever require servicing, a
Return Authorization number (RA) is necessary.  Without this number, the unit will not be
accepted.  If your VM1 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 VM1 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 VHF frequencies can be
found on page 4 of this manual.

System Features

Designed for use in both live sound and sound contracting applications, the Samson VM1
system provides a high performance, cost effective solution, utilizing state-of-the-art
technology in wireless communications.  Main features include:

• Six different available channels, all operating in the VHF bandwidth, and all designed for

simultaneous use.  This means that you can use multiple VM1 systems (each tuned to a
different channel) in the same location without interference.
