• 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 an active 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.
• The unit has been factory adjusted precisely. Do not
tamper with its internal parts or attempt to repair it.
• Do not attempt to recharge an alkaline battery.
• Do not dispose of a battery in fire. Do not disassemble or
short-cirtuit a battery.
• Make sure to use an LR6 (size-AA) alkaline battery.
• Make sure the poles of the battery match the + and –
markings in the battery holder.
• Remove the battery when the unit will not be used for a
long period of time.

Introduction
The WRT-807B is a UHF-synthesized wireless microphone
for use in a 800-MHz band UHF-synthesized wireless
microphone system.
The WRT-807B operates in conjunction with the MB-806A
with WRU-806B UHF Synthesized Tuner Unit for vocal
concentration.
The WRT-807B can be also used with existing Sony
wireless microphone systems consisting of the WRT-805B/
855B UHF Synthesized Transmitter and WRR-805B/855B/
862B UHF Synthesized Tuner, etc.
Transmitting Channel Band
The microphone/transmitter and tuners of wireless
microphone systems are classified by frequency band.
A 24-MHz frequency band is assigned to each microphone/
transmitter and tuner model.
In building a UHF wireless microphone system, be sure to
pair a microphone/transmitter with a tuner that has the same
TV channel number.
Features
Phase Locked Loop (PLL) synthesized system
The WRT-807B features a refined phase locked loop (PLL)
synthesizer circuit.
POWER switch with holding function
The POWER switch can be locked in the ON position to
protect against accidental power cut-offs.
Low-battery notification on tuner
When the microphone battery is low, the microphone sends a
warning to the WRR-805B/862B/WRU-806B in the form of
“Battery status information.”
This information is sent to the WRR-805B/862B/WRU806B about one hour before the battery goes dead to allow
the battery to be safely replaced.
When the WRR-805B/862B/WRU-806B receives this
information, the LED on tuner panel starts to flash.
Powered by readily available battery type
The built-in, high-efficiency DC-DC converter provides
about 5 hours of continuous and stable operation with just a
single LR6 (size-AA) alkaline battery.
2(GB)
LCD readout of various information
The microphones LCD shows the current channel number,
frequency, input attenuation setting, and residual battery
power.
The accumulated battery use time is also indicated (in oneminute increments) to allow precise monitoring of battery
use.
Automatic saving of channel and input attenuation
settings
All channel and input attenuation settings are automatically
saved when the microphone is turned off (and are
maintained even when the battery is removed), thus
eliminating the need to make the same settings again the
next time you use the microphone.
Highly reliable electronic attenuator
Adjustable in a range of 0 dB to 21 dB in 3-dB steps, the
built-in input level attenuator reduces signal distortion
during the input of excessively strong audio signals.
Tone signal-incorporated RF carrier signal
The microphone transmits 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 operation
• When operating two or more microphones, keep the
microphones separated from each other by a distance of at
least 30 cm (1 foot).
• Keep microphones at least 3 meters (10 feet) away from
the receiving antenna.
Wide dynamic range and low noise
The microphones compander (compressor/expander) system
enables transmission over a wide dynamic range with
minimum noise.

Notes
• The microphone cannot transmit in Setting mode.
• Make sure that the channel selected on the microphone is
the same as that selected on the tuner being used in the
same system.
• Depending on the noise or interference conditions, all
selectable channels may not be usable. If necessary, you
can determine which channels are usable by cycling the
channel selection through a number of channels on the
tuner with the microphone set to OFF. Those channels for
which the RF indicator on the tuner does not light are
usable.
• The microphone may not operate correctly if it is turned
on immediately after being turned off in Setting mode.
Wait for a few seconds before turning the power on again.
