• A “Lock” features provides additional
security by allowing you to lock in
the receiver settings electronically.
• Front panel includes a comprehensive set of recessed
controls to select all key functions and a security cover
to physically protect receiver settings.
• Voltage-sensing power supply for world-wide use with
any power-source from 100-240 volts.
• Di-electric filtering to eliminate outband interference.
• Phase-Lock Loop VCO technology.
• Compact, lightweight beltpack transmitter features

Mic Level trimpot control; Frequency Unavailable LED
indicator; RF power switch (to select either one or 10
mW output settings) and a Power On/Off switch.
• Rotary swivel antenna and a rotatable belt clip provide
maximum positioning flexibility.
• P6 connector accommodates Samson’s QE, QV headsets
and a wide range of other headset and lavalier mics.
• Handheld transmitter with built-in antenna.
• Handheld transmitters available with the Samson QMIC
and a variety of other microphone elements.
• Transmitters powered by AA batteries.
• The optional DA6 distribution amp compensates for up
to 9 dB of signal loss typically incurred when combining
and distributing the signal through a number of antennas.
• The DA6 allows up to four UR6D dual receivers (eight
receivers total) to run off the same pair of antennas.
• The DA6 can be interfaced with as many as four powered antennas, further increasing the range of the systems and eliminating “dead spots” to provide more stable operation.
• The DA6 features a multi-color display that indicates the
current status of the connected antennas, Green when
powered antennas are properly connected; Orange if no
antenna is connected; and Red if any of the antennas has
a shorted cable.
• AN-81A & AN82 Powered Antennas are extremely compact, lightweight and efficient and offer a 3-position attenuator switch to reduce near field RF overload and local interference. The AN-81A antenna can be wall-mounted, while
the AN-82 is designed to be mounted on a mic stand.

Designed to provide the highest level of performance
in touring and fixed installations, the new Samson Series
Six UHF Synthesized wireless system combines simultaneous operation of up to 96 systems and remote computercontrol with exceptional frequency agility, superior RF
reception, transparent audio and much more.
Series Six is one of the only UHF wireless systems
which can run up to 96 simultaneous systems in a fixed
installation using a special "low power technique" exclusive to Samson. This versatile system also allows remote
control capability from hundreds of feet away via a PC
running Windows 95® and Samson’s WSM™ (Wireless
System Manager) software. Using a mouse and computer
keyboard, the system operator can control a range of
receiver functions such as Channel; Mute; Tone Squelch
and more.
There is also a spectrum analyzer that scans existing
frequencies in an RF environment, records a "snapshot" of
these frequencies at any given time and imports an
optional channel plan. An electronic lock function allows
the user to store settings with security.
The unusual flexibility of Series Six is based on its
dual 1mW and 10 mW RF power operation capability. At
the lower 1 mW power output rating, up to 48 systems
on two separate frequency bands (Standard and "X" — for
a total of 96 systems) can be operated simultaneously
with a maximum operating range of 140 feet. At the 10
mW power rating, up to 11 systems on two separate frequency bands (Standard and "X" — for a total of 22) can
be used simultaneously with a maximum operating range
of 270 feet.
Series Six delivers fail-safe RF performance and trans-
Dual The UR6D True Diversity Receiver:
parent audio, a result of sophisticated new Samson circuitry and dbx® Noise Reduction. The UR6D (and
UR6DX) dual system receiver is a 1U space, 19" rackmount device with recessed controls, a back-lit LCD display and a protection cover to safeguard control settings.
Equipped with 96 frequencies (101 channels) operating on two separate frequency ranges, the UR6D includes
a 3-position antenna attenuator switch; a Mix switch that
combines both outputs into one, and an automatic voltage sensing power supply for world-wide use. It also features balanced and unbalanced outputs. Remote IN/Out
capability is provided via a Mini DIN connector remotecontrollable via the external host computer.
The UH6 handheld and UT6 beltpack transmitters are
also equipped with 96 frequencies (101 channels) operating on two separate frequency ranges. They use two AA
batteries, another Series Six innovation based on the
increased worldwide availability and cost-effectiveness of
this popular format. A Battery Life LED changes color
from green to red one hour before unit ceases to function. Both transmitters also include a full array of internal
and external controls for maximum effectiveness is different applications.
The lightweight and ergonomically-designed UT6 beltpack transmitter also features a unique rotatable antenna
and belt clip along with a high-quality locking 6-pin
Hirose connector for headset and lavalier mics. Optional
accessories include distribution amplifiers (DA6/DA6X)
that operate with up to 8 receivers each and active antennas in both movable and wall-mount formats, with up to 4
antennas feeding each distribution amp for improved performance against RF "dropouts."
