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 or corrosive 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.

Compact, lightweight and easy to mount on Sony
camcorders
The WRR-862A/862B is extremely compact and
lightweight, housing in the rugged, die-cast magnesium
case. It is easily mounted on Sony camcorders.
Preprogrammed wireless channel plans for simultaneous
multi channel operation
The WRR-862A/862B has many preprogrammed channel
groups, meaning combination of wireless channels to permit
simultaneous operation of multiple channels without
intermodulation.
See “Wireless Microphone System Frequency List” supplied
with this manual.
Extensive information by the LEDs and LCD display
The LEDs indicate each channel RF input level (green/ red
indication), diversity reception status, and transmitter
battery alarm. The LCD display for each tuner indicates the
Overview
The WRR-862A/862B is a highly reliable diversity tuner for
the Sony UHF wireless microphone system to be used for
broadcast or movie production purposes.
This tuner is suitable for Electronic News Gathering (ENG)
and Electronic Field Production (EFP).
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
In building a UHF wireless microphone system, be sure to
combine a microphone/transmitter and a tuner having the
same wireless channel (frequency).
Features
Dual Diversity Tuner
Despite of its compact design, the WRR-862A/862B
simultaneously receives two signal channels. A space
diversity system is employed on both channels to eliminate
signal dropout and provide stable reception. Two SMC9-4S
(Sony 4 pin) audio output connectors are provided on the
top panel.
Wide Operating Frequency ranges
The WRR-862A operates over a 14 MHz frequency band
within the range of 792 MHz to 806 MHz (model available
in Australia) , while the WRR-862B operates over a 24 MHz
frequency band between 470 MHz to 806 MHz (model
available in U.S.A.), or 470 MHz to 862 MHz (model
available in Europe).

level, battery status of the tuner, and the accumulated
operating time.
Long operating time
Approximate five hours of continuous operation is provided
by using four LR6 (size AA) alkaline batteries. The WRR-
862A/862B can also be operated on the external power from
Sony camcorders via the supplied DC cable.
Switchable RF squelch
The RF squelch can be easily turned ON or off with the
panel button. The RF squelch level is selectable from 5 dB

ANT (antenna) a/b connectors
Connect the antennas supplied to both ANT a/b connectors.
Note
Be sure to connect two antennas to these connectors, even
when you use one tuner, to make the diversity reception
properly.

OUTPUT 1/2 (BAL) connectors
The OUTPUT 1 connector supplies audio signal output
from tuner 1, and the OUTPUT 2 connector supplies the
output from tuner 2.
Connect these connectors to the microphone input
connector of a camcorder, mixer, or tape recorder by using
the supplied cable.

RF (radio frequency) indicators
Indicate the strength of the RF input signal and the
receiving antenna for diversity reception of each tuner; the
left pair is for the tuner 1, and the right pair is for the tuner
2.
The indication color shows the strength of the RF input
signal. The indicated signal level changes corresponding to
