The WRR-800A is a reliable UHF synthesized diversity
tuner for the 800-MHz-band Sony UHF wireless
microphone system which uses the frequency bands
allocated for UHF TV broadcasting.
This unit is designed to enable simultaneous use of multiple
channels when channels are selected according to the
channel plan.
In building up a UHF wireless microphone system, be sure
to combine a microphone/transmitter and a tuner having the
same TV channel number (62, 64 or 69).
CE62 model
A 14 MHz frequency band is assigned to the WRR-800A/
CE62 model, permitting it to operate on any of 111
receiving frequencies in 125-kHz steps of Sony original
channel plan or 561 receiving frequencies in 25-kHz steps of
German User Group in the range of TV channels 62 and 63.
The selectable wireless channels and frequencies for this
model are listed pages L-2 through L-10.
CE64 model
A 14 MHz frequency band is assigned to the WRR-800A/
CE64 model, permitting it to operate on any one of 111
receiving frequencies in 125-kHz steps of Sony original
channel plan or 561 receiving frequencies in 25-kHz steps of
German User Group in the range of TV channels 64 and 65.

CE69 model
An 8 MHz frequency band is assigned to the WRR-800A/
CE69 model, permitting it to operate on any of 64 receiving
frequencies in 125-kHz steps of Sony original channel plan
in the range of TV channel 69 or 14 receiving frequencies in
25-kHz steps of UK General Use.
The selectable wireless channels and frequencies for this
model are listed on pages L-20 and L-21.
Features
Phase Locked Loop (PLL) synthesized system
The WRR-800A has a refined phase locked loop (PLL)
synthesizer circuit.
Preprogrammed wireless channel plan for
simultaneous multichannel operation
The WRR-800A has many preprogrammed, easily settable
channels in a simultaneous multichannel operation.
Overview
Versatile display
A liquid-crystal display provides a variety of information,
including the levels of the reception channels, RF
information and transmitter battery alarm.
Space diversity reception system
The WRR-800A provides stable signal reception with
minimum dropout.
Tone squelch circuit for noise elimination
A built-in squelch circuit eliminates noise and signal
interference when the WRR-800A is in signal reception
standby mode.
Compander system
A compander (compressor/expander) system enables
stabilized wireless transmission over a wide dynamic range.

System Configuration
The unit can be used with a Sony UHF synthesized wireless
microphone or UHF synthesized transmitter among the
models listed in the table below.
Sony 800 MHz-band system models
Channel Plan
The unit stores several groups of channels. See “Overview
of Channel Plan” in the “Wireless Channel Lists” section.
Channel groups other than group 00 are designed so that all
channels of one group can be used simultaneously within the
same UHF wireless microphone system without causing
intermodulation. It is therefore recommended that you
usually use a channel group other than group 00 unless the
use of group 00 is specifically necessary.
Note
To eliminate interference or noise, please note the
following.
• Do not use two or more wireless microphones or
transmitters whose wireless channels are the same.
• If there is a TV broadcasting station nearby, to avoid
possible interference from its broadcasting, do not use that
station’s channel.
• The number of wireless microphone channels actually
usable in a multi-channel system may be smaller than the
normal capacity of that system if there is interference from
TV broadcasting or other RF signals.
• When operating two or more UHF wireless microphone
systems using the same wireless channel in the same
group, ensure that the systems are at least 100 m1) apart as
far as they are installed within sight of each other.

Precautions
On cleaning
Clean the unit with a dry, soft cloth. Never use thinner,
benzene, alcohol or any other chemicals, since these may
damage the finish.
On operation
• The unit must be used within a temperature range of 0°C to
40°C. Avoid using the unit for extended periods at
extremely high temperatures or placing it in direct sunlight,
especially outdoors because this may damage the finish of
the case. Never install the unit on or near a heat source,
such as lighting equipment or power amplifiers.
• Avoid using in very humid or dusty places, because such
use may shorten the life of the unit.
• To avoid degradation of the signal-to-noise ratio, do not
use the unit in noisy places or in locations subject to
vibration, such as the following:
— near electrical equipment, such as motors, transformers
or dimmers
— near air conditioning equipment or places subject to
direct air flow from an air conditioner
— near public address loudspeakers
— where adjacent equipment might knock against the unit
• Switching lights on or off may produce electrical
interference over the entire frequency range. Position the
unit and the wireless microphones so that interference is
minimized.
• The unit is precisely adjusted at the factory and no
adjustment before use is necessary. Do not touch the
inside of the unit or try to repair it by yourself.

For details on setting the channels, see page 9.
5Turn on the wireless microphone or transmitter.
Use the wireless microphone or transmitter to which the
same channel is assigned as to this unit.
If noise is heard
Depending on the environment where the system is
installed, outside noise or radio wave may disrupt the
transmission of certain channels.
To select a channel under this circumstance, turn off the
wireless microphone or transmitter. Then select a channel at
which the RF indicator is off. (A channel free from noise or
radio wave interference is selected.) Set the same channel on
the microphone or transmitter.
