• The unit is designed for use in ambient temperature range
of 0°C to 50°C (32°F to 122°F).
• Do not place the unit on or near heat sources, such as
lighting equipment, power amplifiers, or in a place subject
to direct sunlight or excessive moisture. In such places,
the external finish or internal parts of the unit may be
damaged.
• If the unit is used in a very humid or dusty place or in a
place subject to expose to an active or corrasive gas, clean
its surface as well as the connectors with a dry, soft cloth
soon after use.
Lengthy use of the unit in such places or not cleaning it
after its use in such places may shorten its life.
• When cleaning the unit, never use organic solvents such as
thinners or benzine, which will damage the finish of the
unit.
• Using the unit with wet hands may cause trouble in the
unit.
• The unit has been factory adjusted precisely. Do not
tamper with its internal parts or attempt to repair it.
• Make sure to use two LR6 (size-AA) alkaline batteries.
• Make sure the poles of the batteries match the + and –
markings in the battery holder.
• Remove the batteries when the unit will not be used for a
long period of time.
• Do not attempt to recharge the alkaline batteries.
• Do not dispose of the batteries in fire. Do not disassemble
or short-circuit the batteries.

Introduction
Coupling with the CU-F780, CU-G780, CU-E700, CU-E672
or CU-F117 Sony Microphone Capsule Unit, the WRT-847A/
847B UHF-synthesized transmitter unit makes up a UHF-
synthesized wireless microphone to be used in a UHF-
synthesized wireless microphone system.
For vocal concentration, operate the WRT-847A/847B in
conjunction with the WRR-802A/850A, MB-806A with
WRU-806A UHF Synthesized Tuner. For vocal and
interview use, operate the WRT-847A/847B in conjunction
with the WRR-805A/855A UHF Synthesized Tuner.
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
A 24 MHz frequency band (a 14 MHz frequency band:
model available in Australia) is assigned to each
microphone/transmitter and tuner model.
In building up a UHF wireless microphone system, be sure
to combine a microphone/transmitter and a tuner having the
same TV channel number.
Features
Selectable microphone capsules
To make up suitable wireless microphones for your use, five
microphone capsule units are available as optional
accessories. The capsule units for the WRT-847A/847B are;
CU-F780 Super Cardioid Dynamic Microphone Unit
CU-G780 Super Cardioid Dynamic Microphone Unit
for Live Vocal Performance
CU-E700 Super Cardioid Electret Condenser
Microphone Unit
CU-E672 Hyper Cardioid Electret Condenser
Microphone Unit (Short-shotgun)
CU-F117 Omni-directional Dynamic Microphone Unit
The capsule unit can be mounted simply by screwing it into
the transmitter.
Phase Locked Loop (PLL) synthesized system
The WRT-847A/847B features a refined phase locked loop
(PLL) synthesizer circuit.
Wide dynamic range and low noise
The compander (compressor/expander) system enables
transmission over a wide dynamic range with minimum
noise. The compander time constant is selectable to get the
optimum sound quality of the individual microphone
capsule.
3(GB)
Selectable RF output
The RF output power can be adjusted to high (50 mW) or
low (10 mW) to match the environment where it will be
used; to obtain a wide service area, set this to 50 mW, and
when using the transmitter in a simultaneous multi-channel
system, set it to 10 mW.
Highly reliable audio gain level adjustment
With an adjustable range of –12 dB to +9 dB in 3 dB steps,
the built-in input level volume reduces signal distortion
during the input of excessively strong audio signals. It can
raise the input gain during too low audio input.
POWER switch with holding function
The POWER switch can be locked in the ON position to
protect against accidental power cutoffs.
Powered by readily available battery type
The built-in, high-efficiency DC-DC converter provides
about eight hours of continuous and stable operation with
two LR6 (size-AA) alkaline batteries.
Low-battery notification on the unit and the tuner
When the transmitter batteries are low, the transmitter sends
a warning to the WRR-802A/805A/850A, MB-806A with
WRU-806A in the form of “Battery status information.”
This information is sent to the WRR-802A/805A/850A,
MB-806A with WRU-806A about one hour before the
batteries go dead to allow the batteries to be safely replaced.
When the WRR-802A/805A/850A, MB-806A with
WRU-806A receive this information, the LED and the
LCD1) display on tuner panel start to flash.
LCD1) read-out of various information
The transmitter's LCD1) display shows the current channel
number, frequency, audio gain, compander time constant,
RF output settings and residual battery power.The
accumulated battery use time is also indicated (in one-
minute increments) to allow precise monitoring of battery
use.
Automatic saving of channel, audio gain and RF
output settings
All channel, audio gain, compander time constant, and RF
output settings are automatically saved when the transmitter
is turned off, thus eliminating the need to make the same
settings again the next time you use the transmitter.
Tone signal-incorporated RF carrier signal
The transmitter sends an RF carrier signal that incorporates
a tone signal to enable any tuner with a tone squelch circuit
to pick out only the target audio signal.
Notes on simultaneous multi-channel
operation
When operating two or more transmitters simultaneously in
a multi-channel system, please note the following.
• Set the RF output power of the transmitters to 10 mW.
• Keep the transmitters separated from each other by a
distance of at least 30 cm (1 foot).
• Keep the transmitters at least 3 meters (10 feet) away from
the receiving antenna.
