Introduction / System Features
Congratulations on purchasing the Samson 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 UHF Series One system you have purchased
operates in the 801 - 805 MHz frequency range and contains a UR1 receiver and either
our UT1L belt-pack transmitter (for lavalier microphone or headset applications), UT1G
belt-pack transmitter (for instrument applications) or UH1 hand-held microphone
transmitter (available in a wide variety of popular capsules).
In this manual, you’ll find a more detailed description of the features of the UHF Series One
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 UHF
Series One 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 UHF Series One system was purchased outside of
the U. S., contact your local distributor for warranty details.
SPECIAL NOTE for U.S. purchasers: Should your UHF Series One system ever require
servicing, a
Return Authorization number (RA) is necessary. Without this number, the unit
will not be accepted. If your UHF Series One 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
UHF Series One 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.
System Features
Designed for use in both live sound and sound contracting applications, the Samson UHF
Series One Wireless 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 less crowded UHF bandwidth, and all
designed for simultaneous use. This means that you can use multiple Series One
systems (each tuned to a different channel) in the same location without interference.
•Technological breakthrough usage of SAW (Surface Acoustic Wave) filters (similar to
those used in high-end television receivers) for extremely precise and stable tuning.
•True Diversity technology maximizes active range (up to 300 feet) and reduces potential
interference problems through automatic switching between two independent receivers.

System Features
•The UR1 receiver is a half-rack unit that can be used freestanding or can be mounted in
any standard 19" rack,* making it easy to integrate into any traveling or fixed installation
audio system. It includes a pair of tuned antennas and provides both balanced and
unbalanced outputs, line/mic output level switch and continuously adjustable AF level
and mute controls, as well as an audio peak LED, dual receiver indicators, and a fivesegment RF level meter.
•Built-in companding noise reduction in all components for crystal-clear sound with
minimized background noise and hiss.
•Transmitters provide “popless” muting (which turns off the audio signal while leaving the
carrier signal on) and use standard 9-volt batteries, with battery life of more than
12 hours. Transmitters also provide a convenient three-segment multicolor Battery
Strength LED meter, allowing you to monitor the remaining power in the installed battery.
•Incredibly compact “beeper-sized” UT1L and UT1G belt-pack transmitters are extremely
lightweight (less than 4 ounces with a 9-volt battery installed). The UT1G comes
prewired with permanent connection to a standard 1/4" jack (for use with instruments
such as electric guitar or bass), while the UT1L provides a Switchcraft TB3M mini-XLR
jack for connection to a variety of popular headsets and lavalier microphones, including:

Guided Tour - UR1 Front Panel
1: Antennas (A and B) - The antenna mountings allow full rotation for optimum
placement. In normal operation, both Antenna A (the antenna on the left) and Antenna B
(the antenna on the right) should be placed in a vertical position. Both antennas can be
folded inward for convenience when transporting the UR1. See the “Setting Up and Using
the Series One System” section on page 8 in this manual for more information about
antenna installation and positioning.
2: AF (Audio Frequency) Level control - This knob sets the level of the audio signal
being output through both the balanced and unbalanced output jacks on the rear panel.
Reference level is obtained when the knob is turned fully clockwise (to its “10” setting).
3: Peak LED - This LED lights yellow when output signal from the UR1 is at the onset of
clipping (that is, when it is on the verge of being distorted). If you see this light during
operation, move the microphone further away or lower the output level of your instrument
or transmitter. For more information, see the section entitled “Setting Up and Using the
Series One System” on page 8 in this manual.
4: A/B Receiver LEDs - When signal is being received, one of these will be lit green,
showing you whether the (left) “A” or (right) “B” receiver is currently being used. The UR1
constantly scans its two antennas 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.
5: RF (Radio Frequency) Level meter - This five-segment meter (similar to the VU bar
meter used on audio devices) indicates the strength of the UHF signal being received.
When all segments are lit, the incoming RF signal is at optimum strength; when only the
left-most segment is lit, the incoming RF signal is at minimum strength. If no segments are
lit, no signal is being received; check to ensure that the transmitter is on and that it is set to
the same channel as the UR1. See the “Setting Up and Using the Series One System”
section on page 8 in this manual for more information.
6: Power LED - This lights red whenever the UR1 is turned on.
7: Mute (squelch) control - This control determines the maximum range of the UR1
before audio signal dropout. Although it can be adjusted using the supplied plastic
screwdriver, it should normally be left at its factory setting. See the “Setting Up and Using
the Series One System” section on page 8 in this manual for more information.
8: Power switch - Use this to turn the UR1 power on and off. When the receiver is on, the
Power LED (see #6 above) is lit.

1: DC input - Connect the supplied 12 volt 160 mA power adapter here, using the strain
relief as shown in the illustration below. WARNING: Do not substitute any other kind of
power adapter; doing so can cause severe damage to the UR1 and will void your warranty.
2: Unbalanced output* - Use this unbalanced high impedance (5K Ohm) 1/4" jack when
connecting the UR1 to consumer (-10) audio equipment. Wiring is as follows: tip hot,
sleeve ground.
3: Audio Output Level switch - Sets the audio output level attenuation of the balanced
output (see #4 below) to -20 dBm (line level) or -40 dBm (mic level). See the “Setting Up
and Using the Series One System” section on page 8 in this manual for more information.
4: Balanced output* - Use this electronically balanced low impedance (600 Ohm) XLR
jack when connecting the UR1 to professional (+4) audio equipment. Pin wiring is as
follows: Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).
* If required, both the unbalanced and balanced outputs can be used simultaneously.

Guided Tour - UT1L / UT1G
1: Input connector - The input device is connected here. The UT1L is supplied with
either a lavalier or headset microphone (connected via a Switchcraft mini-XLR jack), while
the UT1G is supplied with a permanently connected 1/4" jack cable.
2: Battery level meter - This set of three multicolor LEDs indicates relative battery
power, indicating whether the installed battery is at low (red), mid (yellow) or high (green)
strength. One of these will light whenever the UT1L or UT1G is powered on (see #8 on
the next page). When the red “low” indicator lights, RF performance is degraded and the
battery needs to be replaced.
3: Audio on-off switch - When set to the “on” position, audio signal is transmitted.
When set to the “off” position, the audio signal is muted. Because the carrier signal
remains during muting, no “pop” or “thud” will be heard. Note that turning this off does
not
turn off the transmitter power—it is simply a way to temporarily mute the transmission of
audio signal. If you don’t plan on using the transmitter for extended periods, turn off the
transmitter power by using the power on-off switch (see #8 on the next page).
4: Belt clip - Use this clip to fasten the UT1L or UT1G to a belt. The position of the clip
can be rotated to the desired position after loosening its
center screw or can be removed entirely by removing
the center screw.
5: Battery cover release - Slide the release lever down
to open the UT1 battery cover.
6: Antenna - This permanently attached transmitter
“pig tail” antenna should be fully extended for normal
operations. See the “Setting Up and Using the Series
One System” section on page 8 in this manual for more
information about antenna positioning.
7: Battery holder - Insert a standard 9-volt alkaline
battery here, being sure to observe the plus and minus
polarity markings shown. We recommend the Duracell
MN 1604 type battery. Although rechargeable Ni-Cad
batteries can be used, they do not supply adequate
current for more than four hours.
WARNING: Do not
insert the battery backwards; doing so can cause severe
damage to the UT1L / UT1G and will void your warranty.

9: Audio Input Level control (trimpot) - This input sensitivity control has been factory
preset to provide optimum level for the particular lavalier or headset model being used
(in the case of the UT1G, it is preset for optimum instrument level) and so we recommend
that this not be adjusted manually. If necessary, however, you can use the supplied plastic
screwdriver (see #10 below) to raise or lower the UT1L / UT1G input level. See the
“Setting Up and Using the Series One System” section on page 8 in this manual for more

Setting Up and Using the Series One System
The basic procedure for setting up and using your UHF Series One Wireless System
takes only a few minutes:
1. For the Series One system to work correctly, both the receiver and transmitter must be
set to the same channel. Remove all packing materials (save them in case of need for
future service) and check to make sure that the supplied UR1 receiver and UT1L, UT1G
or UH1 transmitter are set to the same channel. If these channels do not match, contact
your distributor or, if purchased in the United States, Samson Technical Support at
1-800-372-6766.
2. Physically place the UR1 receiver where it will be used (the general rule of thumb is to
maintain “line of sight” between the receiver and transmitter so that the person using or
wearing the transmitter can see the receiver). An optional rack-mount kit (available from
your Samson dealer) allows the UR1 to be mounted in a standard 19" rack if desired.
Extend both “A” and “B” antennas and place both in a vertical position.
3. Make sure the Power on-off switch in your UT1L / UT1G belt-pack or UH1 handheld
transmitter is set to “Off.”
4a. If your system contains a UT1L or UT1G belt-pack transmitter, locate the battery
cover release and slide the lever down to open the battery door, which is hinged and not
intended to be removed from the transmitter case. Please use care when opening this
door as undue force will destroy the hinge.
4b. If your system contains a UH1 handheld transmitter, unscrew the bottom section of
the microphone by turning it counterclockwise and then slide it off.
5. Place a fresh 9-volt alkaline battery in the transmitter battery holder, taking care to
observe the polarity markings. If you are using a UT1L or UT1G belt-pack transmitter,
gently replace the battery door by swinging it up and pressing until it clicks. If you are
using a UH1 handheld transmitter, replace the bottom section of the microphone by sliding
it on and then screwing it back on. Whichever transmitter you are using, leave it off for the
moment.
6. Make the physical cable connection between the UR1 output jack and the line or mic
level audio input of your amplifier or mixer. If you are using the balanced XLR jack
(preferable, since it will deliver an electromagnetically cleaner signal), be sure to set the
UR1 rear panel Audio Output Level switch correctly. If required, both the balanced and
unbalanced outputs can be used simultaneously. Leave your amplifier (and/or mixer) off
at this time.
7. Turn the AF Level knob on the UR1 completely counterclockwise. Using the strain
relief, connect the supplied AC adapter to the DC Input on the rear panel of the UR1, then
plug the adapter into any standard AC outlet. Press the front panel Power switch to turn
on the UR1; the red “Power” LED will light up, but all other front panel LEDs will remain
unlit.
8. Turn on the power to the UT1L, UT1G or UH1 transmitter (using its Power on-off
switch); the green “HIGH” Battery strength LED will light if the battery is sufficiently strong.
At this point, either the “A” or “B” green LED on the front panel of the UR1 will light
(depending upon which antenna is receiving the stronger signal). Also, one or more
segments in the UR1 front panel RF Level meter should light; the more are lit, the stronger
the RF signal. If only one or two segments light (indicating a relatively weak signal), try
relocating the UR1 or changing the position of one or both of its antennas. If all five
segments light, the UR1 is receiving an optimally strong RF signal and is placed and
positioned correctly.
ENGLISH
11
Setting Up and Using the
Series One System
9. Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but
keep its volume all the way down. Next, make sure that your transmitter is unmuted by
setting its Audio switch to “On.” Then set the AF Level knob on the UR1 fully clockwise
(to its “10” setting); this is unity gain. If you are using the UH1 transmitter or if you are
using the UT1L transmitter with a connected lavalier microphone or headset, speak or sing
into the mic at a normal performance level while slowly raising the volume of your
amplifier/mixer until the desired level is reached. If you are using the UT1G transmitter
with a connected instrument, play the instrument at normal performance level while slowly
raising the volume of your amplifier/mixer until the
desired level is reached. If you are using a UT1L
beltpack transmitter equipped with a lavalier
microphone, note that correct lavalier placement is
critical to sound quality. We recommend that you
place it as shown in the illustration on the right—as
close to your mouth as possible but off to one side
(to minimize nasality) and unobstructed by clothing.
Bear in mind also that
omni microphones (mics which
pick up signal from all directions) are more prone to
feedback problems than
unidirectional (cardioid or
supercardioid) ones; in general, you can avoid
feedback by taking care not to use any microphone
directly in front of a PA speaker (if this is
unavoidable, try using an equalizer to attenuate those
high- or mid-range frequencies which are causing the
feedback “squealing”).
10. If you hear distortion at the desired volume level, first check to see whether the yellow
“Peak” LED on the UR1 is lit. If it is not, make sure that the gain structure of your audio
system is correctly set (consult the owners manual of your mixer and/or amplifier for
details). If the yellow “Peak” LED
is lit, do the following:
• If you are using a UH1 transmitter, use the supplied plastic screwdriver to turn its
Microphone Input Level control (trimpot) slowly counterclockwise (towards the “Min”
position) until the distortion disappears.
• If you are using a UT1L transmitter with connected lavalier microphone or headset, its
Audio Input Level control has been factory preset to provide optimum level for the
particular lavalier or headset model being used and so no adjustment should be
necessary. Any distortion present should therefore simply be a matter of the
microphone being too close to the mouth; try moving it further away. If this does not
solve the problem, use the supplied plastic screwdriver to turn the Audio Input Level
control (trimpot) on the UT1L slowly counterclockwise until the distortion disappears.
• If you are using a UT1G transmitter with an instrument such as electric guitar or bass,
lower the output level of the instrument until the distortion disappears. Alternatively,
you can use the supplied plastic screwdriver to turn the Level control (trimpot) on the
UT1G slowly counterclockwise until the distortion disappears.
Note that, following this setup procedure, you can always lower the AF Level knob of the
UR1 in order to attenuate the output signal if necessary.

11. Conversely, if you hear a weak, noisy signal at the desired volume level, again make
sure that the gain structure of your audio system is correctly set (consult the owners
manual of your mixer and/or amplifier for details) and that the AF Level control of the UR1
is fully clockwise (at its “10” setting). If it is and the signal coming from the UR1 is still
weak and/or noisy, do the following:
• If you are using a UH1 transmitter, use the supplied plastic screwdriver to turn the
Level control (trimpot) on the transmitter slowly clockwise (towards the “Max” position)
until the signal reaches an acceptable level.
• If you are using a UT1L transmitter with connected lavalier microphone or headset, its
Level control has been factory preset to provide optimum level for the particular
lavalier or headset model being used and so no adjustment should be necessary.
Any weakness of signal should therefore simply be a matter of the microphone being
too far from the mouth; try moving it closer. If this does not solve the problem, use the
supplied plastic screwdriver to turn the Level control (trimpot) on the UT1L slowly
clockwise until the signal reaches an acceptable level.
• If you are using a UT1G transmitter with an instrument such as electric guitar or bass,
raise the output level of the instrument until a good signal is achieved. Alternatively,
you can use the supplied plastic screwdriver to turn the Level control (trimpot) on the
UT1G slowly clockwise until the signal reaches an acceptable level.
12. Temporarily turn down the level of your mixer/amplifier system and turn off the power
to your transmitter, leaving the UR1 on. Then restore the previously set level of your
mixer/amplifier. With the transmitter off, the receiver output should be totally silent—if it is,
skip ahead to the next step. If it isn’t (that is, if you hear some noise), you may need to
adjust the UR1 front panel Mute (squelch) control. When the Mute control is at its
minimum setting, the UHF Series One system always provides maximum range without
dropout; however, depending upon the particular environment your system is used in, you
may need to reduce that range somewhat in order to eliminate band noise when the
transmitter is turned off. To do so, use the provided screwdriver to rotate the Mute control
completely counterclockwise (to the “Min” position), then slowly turn it clockwise until the
noise disappears. If no noise is present at any position, leave it at its fully
counterclockwise “Min” position (so as to have the greatest overall range available).
13. When first setting up the UHF Series One System in a new environment, it’s always a
good idea to do a walkaround in order to make sure that coverage is provided for your
entire performance area. Accordingly, turn down the level of your audio system and turn
on both the transmitter and receiver. Then, with the transmitter unmuted, restore the level
of your audio system and while speaking, singing, or playing your instrument, walk through
the entire area that will need to be covered. As you do so, you will find that the green “A”
and “B” LEDs on the UR1 receiver occasionally switch on or off, always showing you which
antenna is receiving the stronger signal. Always try to minimize the distance between
transmitter and receiver as much as possible so that the strongest possible signal is
received from all planned transmission points. In fixed installations such as A/V or
corporate conference rooms or for extended range applications (where the transmitter and
receiver are more than 150 feet apart), it may be desirable to angle the antennas differently
from their vertical position or to install the receiver in the same room as the transmitters
(and, if necessary, to extend the wiring to remote audio equipment).
If you have followed all the steps above and are experiencing difficulties, contact your local
distributor or, if purchased in the United States, call Samson Technical Support
(1-800-372-6766) between 9 AM and 5 PM EST.
