* LX TD systems purchased with the T2G instrument belt-pack
transmitter include a R22 receiver; all other LX TD systems include
a R22X receiver; these two models differ only in that the R22X
provides a rear-panel balanced XLR output jack.
SPECIAL NOTE: Should your unit ever require servicing, a Return
Authorization number (RA) is necessary. Without this number, the unit
will not be accepted. Please call Samson at 1-800-372-6766 for a
Return Authorization number prior to shipping your unit. Please retain
the original packing materials and, if possible, return the unit in its
original carton and packing materials.
In this manual, you ' ll find a more detailed description of the features of
your VLX / VLX TD system, as well as a guided tour through all compo ­
nents, step-by-step instructions for setting up and using your system,
information about Samson Noise Suppression, trouble-shooting tips, a
frequency conversion chart, a technical description of True Diversity,
rack-mounting instructions, a glossary of terms, and full specifications.
You ' ll also find a warranty card enclosed — don ' t forget to fill it out and
mail it in! This will enable you to receive online technical support and
will allow us to send you updated information about these and other
Samson products in the future.
The VLX and VLX TD VHF Wireless Systems differ in that the VR2
receiver provided in the VLX system utilizes non-diversity technology,
incorporating a single antenna for ease of use, while the VR22 and
VR22X receivers* provided in the VLX TD system utilize a system called
" Microprocessor True Diversity " (patent-pending). In this system, a
single chassis (the VR22/22X) houses two antennas (called " Antenna A "
and " Antenna B " ) and one receiver circuit. A built-in computer chip con ­
tinuously scans RF signals from the two antennas and determines which
one has the clearest and strongest reception, automatically (and silently)
switching that signal to the receiver. This allows you to maintain the
wireless communication link over a broader range than would be
allowed by a receiver utilizing a single antenna and also reduces inter ­
ference and phase cancellation problems. In addition, special sample-
and-hold linking circuitry ensures that correct phase correlation is main ­
tained at all times, with no noise or pops during antenna switching. Both
systems utilize the Samson Noise Suppression system and both provide
excellent performance and the highest quality audio fidelity.
Congratulations on purchasing the Samson VLX / VLX TD VHF Wireless
System! Although this product is designed for easy operation, we sug ­
gest 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 transmit ­
ter 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 VLX / VLX TD system you have purchased contains either a
VR2, VR22 or VR22X receiver and either a VT2L microphone belt-pack
transmitter (for lavalier microphone and headset applications), a VT2G
guitar belt-pack transmitter (for instrument applications) or a VH2 hand ­
held microphone transmitter. Here ' s an illustration that shows an
overview of our system design:

* Your receiver and transmitter have been factory preset to utilize the
same channel. A listing of the thirteen available channels and their cor ­
responding HF frequencies can be found on page 26 of this manual.
