Introduction
Congratulations on purchasing the Samson UHF Synthesized True
Diversity Wireless System! Although this product is designed for easy
operation, we suggest you take some time out first 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. The Samson UHF Synth System you have
purchased contains either our UT-5 belt-pack transmitter (for lavalier
microphone, headset microphone, and guitar applications) or our UH-5
hand-held microphone transmitter. The matching receiver is either our
UR-5 single diversity model (for reception of a single monophonic
signal), or our UR-5D dual diversity model (for reception of two monophonic signals or a stereo signal). Here’s an illustration that shows an
overview of our system design:

Introduction
The concept behind a “true diversity” wireless system is that a single
chassis houses two discrete receivers (called “channel A” and “channel
B”) instead of one, with both tuned to the same frequency but with each
using an independent antenna. A built-in computer chip then continuously scans the two receivers and determines which one has the clearest and strongest reception, automatically (and silently) switching to that
channel. This allows you to maintain the wireless communication link
over a much broader area range than would be allowed by a single
receiver and also virtually eliminates interference and phase cancellation problems. In addition, our special circuitry, which utilizes the UHF
(Ultra High Frequency) band, delivers the highest-quality sound
available in any wireless system. Finally, the provision of dbx® noise
reduction* produces crystal-clear sound with minimized background
noise and hiss. Your UHF Synthesized True Diversity System may also
optionally include a DA-5L UHF Antenna Distribution Amplifier. For
more information on this device, see pages 28 - 33.
In this manual, you’ll find a more detailed description of the features of
this system, as well as a guided tour through all components, step-bystep instructions for setting up your system, trouble-shooting tips, wiring
diagrams and tables, 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!
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.

System Features
The Samson UHF Synthesized True Diversity System utilizes state-ofthe-art technology in wireless communications. Here are some of its
main features:
• 74 available channels organized in 10 different groups in both the
receiver and transmitter, with up to 11 channels available for simultaneous use. This makes our UHF Synth System the ideal choice in
multi-user environments such as stage productions and live band
performance. It is also specifically suited for systems that travel into
“hostile” RF environments (such as highly populated urban areas,
where large numbers of radio transmissions occur simultaneously
over broad bandwidth areas).
• The use of the UHF (Ultra High Frequency) band as opposed to VHF
(Very High Frequency), which yields better signal-to-noise ratio and
improved frequency response—in plain English, superior sound
quality. The UHF band is also considerably less crowded than VHF,
thus minimizing potential interference problems. In addition, our
special
dielectric filtering circuitry (which, incidentally, is based upon
cellular phone technology) provides extra narrow bandwidths, thus
further reducing interference.
• True Diversity technology, which greatly extends the effective range
of the system and also virtually eliminates interference and phase
cancellation problems.
• Built-in dbx® noise reduction circuitry in both the transmitter and
receiver. This ensures clear, transparent sound with an absolute
minimum of background noise and hiss.
• A clear, easy-to-read visual display that shows continuous RF
(Radio Frequency) level (indicating the strength of the received signal) as well as AF (Audio Frequency) level. The RF level display also
shows the clearest frequency to use in crowded wireless environments.
• Balanced and unbalanced audio outputs on both the UR-5 and
UR-5D receivers, making them compatible with all types of external
audio mixers and amplifiers.

System Features
• The UT-5 and UH-5 transmitters both accept standard 9-volt
alkaline batteries, and the UR-5 and UR-5D receivers can accept
any AC power voltage from 100 - 250 volts, without the need to
change a voltage selector switch (our special current and voltage
sensing circuitry does the job automatically for you).
• Tuned coaxial antennas are included, with options for rear-mounting
or remoting if extended range is required.
• The UR-5D dual receiver actually contains
two separate true
diversity receivers in a single chassis for the reception of two discrete monophonic signals or a stereo signal. It also provides an
option for output mixing, which combines the received signals from
both inputs into a single monophonic output—critical when using
audio mixers with limited numbers of channels.
• All components utilize an automatic
tone squelch feature that
prevents the reception of unwanted signals.
• The UT-5 belt-pack transmitter is extremely light-weight (less than 4
ounces with a 9-volt battery installed) and is suited for a wide range
of lavalier and headset mics and instruments such as electric guitar
and bass. It also provides phantom powering, making it compatible
with professional condenser lavalier and headset microphones.
• The UH-5 hand-held microphone transmitter features an all-brass
housing painted with a durable epoxy base. A selection of mic
capsules are available, including:
Electro Voice
757 N/DYM Dynamic
Electro Voice
857 N/DYM Dynamic
Sennheiser MKE-4032 Condenser
Shure SM58 Dynamic
Shure SM87 Condenser
Shure
SM85 Condenser
• Both the UT-5 and UH-5 transmitters provide “popless” muting,
which turns off the audio signal while leaving the carrier signal on.
• All components have rugged construction that ensures reliable
operation in even the most demanding performance environments.

Guided Tour - UR-5/UR-5D
Front Panel
1: Power switch - Use this to turn the main power on and off. When
the receiver is on, the display section (see #5 on the next page) is lit.
2: Antenna A and B mountings - Connect the supplied antennas to
these mountings. Third-party receiver antennas should not be substituted—use only the antennas provided with your receiver.
3: Group knob - Allows you to select any of ten frequency Groups
(numbered from 0 - 9). When using the Samson UHF Synth System in a
multiuser environment (that is, when there are two or more transmitters
and receivers in use at one location), all receivers
must be set to the
same Group in order to avoid intermodulation distortion. Each individual
performer is then assigned an individual Channel within that Group
(up to eleven channels are available simultaneously*).
4: Channel knob - Allows you to select any of ten frequency Channels
(numbered 0 - 9) within the selected Group.* When a new channel is
selected, it takes approximately five seconds for audio signal to be
passed through to the receiver outputs.
* Only group 9 has more than seven available channels; all other groups
use channels 0 - 6. Refer to the UHF Frequency Chart on page 24 for
more details.

Front Panel
5: Display section - Shows you information about the current status of
your receiver.
5a: “A”/“B” LEDs - When signal is being received, one of these LEDs
(which shows you whether the “A” or “B” channel is currently being
used) will be lit. A computer chip inside the receiver constantly scans
the two and automatically selects whichever is receiving the strongest,
clearest signal. This “true diversity” switching is completely inaudible,
but it effectively increases overall range while virtually eliminating
potential interference and phase cancellation problems.
5b: “Available” LED - When lit, the selected Group and Channel (as
determined by the Group and Channel knobs) is available for use.
When off, the selected Group and Channel is unavailable and cannot be
used. See the reference chart on page 24 for more information.
5c: “Mute” LED - Lights to indicate the absence of carrier signal. As
described on page 20 of this manual, setting the UT-5 or UH-5 Audio
switch to the “on” position operates a tone squelch feature by causing
a 38.4 kHz signal to be added to the carrier. The illuminated word
“MUTE” in the UR-5 and UR-5D display is a visual representation of the
absence of this 38.4 kHz signal. When “MUTE” is lit, either the transmitter Audio switch is in the “off” position or the currently selected Group
and Channel do not match that of the transmitter.
5d: RF (Radio Frequency) Level display - This “ladder” display (simi-
lar to the VU bar meter used on audio devices) indicates the strength of
the UHF signal being received. When all five segments are lit, the
incoming signal is at maximum strength; when only the left-most segment is lit, the incoming signal is at minimum strength. If no segments
are lit, no signal is being received; check to ensure that the transmitter
and receiver are set to the same Group and Channel (see the “Troubleshooting” section on page 21 for more details).

Front Panel
5e: AF (Audio Frequency) Level display - This “ladder” display (simi-
lar to the VU bar meter used on audio devices) indicates the presence of
audio signal. When all five segments are lit, the outgoing signal is at
maximum strength; when only the left-most segment is lit, the outgoing
signal is at minimum strength. If no segments are lit, little or no signal is
being output; see the “Trouble-shooting” section on page 21 for more
details.
6: AF (Audio Frequency) Level - This knob determines the level of the
audio signal being output through both the balanced and unbalanced
output jacks on the rear panel.
NOTE: The UR-5D front panel (as shown below) is identical to that of the
UR-5 except that it provides two display sections and two group, channel, and AF level knobs—one for each of its two True Diversity receivers.
