FREQUENCY SELECTABLE
TRUE DIVERSITY
WIRELESS SYSTEMS
Featuring advanced wireless technology,
Samson’s new UHF Synth 32 system provides 32
selectable UHF frequencies. Designed for world-
wide use, Synth 32 features a compact half-rack
receiver with a large, amber-colored LCD display
on the front panel. The system includes PLL syn-
thesized VCO circuitry in the transmitters to opti-
mize use in multi-user situations and SAW (Surface
Acoustic Wave) filters in the receiver for optimum
RF performance. The system also includes built-in
Noise Squelch circuitry to reduce wide band noise.
• Synthesized UHF wireless system with 32
selectable frequencies
• Optimized for Worldwide use
• Sleek half-rack design with optional rack-
mount kit
• Amber-colored LCD on receiver front panel
displays Frequency, Channel, Group, Band,
AF/RF level and Diversity A/B antenna
• Built-in Noise Squelch circuitry mutes wide-
band noise in receiver when white noise
exceeds RF level
• Front panel Squelch control
• Compact transmitters feature PLL synthesized
VCO technology to eliminate spurious emis-
sions in multi-user venues.
• R32 receiver features sophisticated SAW
(Surface Acoustic Wave) filters for discriminat-
ing wireless performance

ARCHITECT’S & ENGINEER’S
SPECIFICATION
The Samson UHF Synth 32 Wireless System shall be of a
selectable-channel type using PLL synthesized VCO circuitry
yielding 32 selectable frequencies. Synth 32 operates in the
800 MHz frequency range. The System shall include a belt-
pack or handheld Transmitter and a Receiver, and shall
allow operation of at least six simultaneous systems on sep-
arate channels. The Transmitter and Receiver shall incorpo-
rate compander circuitry for noise reduction and maximum
dynamic range.
The Receiver shall provide balanced XLR and unbal-
anced 1/4″outputs. The audio output level and squelch
shall be adjustable via the front panel. The Receiver shall
incorporate an amber-colored LCD on the front panel dis-
playing Frequency, Channel, Group, Band, AF/R level and
Diversity A/B antenna. The Receiver shall have built-in
Noise Squelch circuitry which mutes wide band noise in
the receiver when wide band noise exceeds the RF level.
The Receiver shall incorporate True Diversity circuitry for
automatic antenna switching. The Receiver shall use two
tuned, molded 1/4 wave rod antennas. The Receiver shall
be powered by 115 VAC, 50/60 Hz via a supplied 12 VDC
adapter. The Receiver shall be notified under FCC rules,
Part 15, and DOC certified under RSP 121. Dimensions of
the Receiver shall be 7.8″(198 mm) wide, 5.5″(140 mm)
deep and 1.7″(42 mm; one rack space) high. Weight of the
Receiver shall be 13.6 oz. (385 g).
The Beltpack Transmitter shall provide either a micro-
phone-level input on a Switchcraft TA3F P3-type connector
or an instrument-level input on a 1/4″phone connector.
The beltpack audio input sensitivity or handheld micro-
phone output level shall be adjustable with a variable atten-
uator. The Transmitter shall incorporate a three-segment
battery life LED meter and the handheld transmitter shall
use an internal dipole antenna while the beltpack transmit-
ter shall use a attached pigtail antenna. The Transmitter
shall be powered by a 9 V alkaline battery and shall provide
a nominal battery life of not less than 12 hours. The
Transmitter type shall be accepted under appropriate FCC
rules.
Transmitter shall be 2.6″(66 mm) wide, 4″(102 mm) deep
and 0.9″(24 mm) high. Weight of the beltpack Transmitter
shall be 2.8 oz. (80 g). The System shall carry a three-year war-
ranty.
The System shall be a SAMSON SYNTH 32
WIRELESS SYSTEM.
