WARNING
To prevent fire or shock hazard, do not expose the unit
to rain or moisture.
To avoid electrical shock, do not open the cabinet.
Refer servicing to qualified personnel only.
On operation
• The unit must be used within a temperature range of 0°C to
40°C (32°F to 104°F). 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.
• To 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.
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.

Table of Contents Overview
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 Sony
channel plan.
Features
Phase Locked Loop (PLL) synthesized system
The WRR-800A has a refined phase locked loop (PLL)
synthesizer circuit and covers two UHF TV channels. It
operates on 102 channels over a 14-MHz frequency.
Preprogrammed wireless channel plan for
simultaneous multichannel operation
The WRR-800A has many preprogrammed, easily settable
channels in a simultaneous multichannel operation. One
group allows setting of 102 channels. The unit also has 12
preset groups of channels, each of which permits ,
simultaneous operation of 5, 6, 8, 9 or 12 channels without
the effects of intermodulation.
4
Versatile display
A liquid-crystal display provides a variety of information,
including the levels of the reception channels, RF
information and transmitter battery condition.
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.
Overview
System Configuration
The unit can be used with a Sony UHF synthesized wireless
microphone or UHF synthesized transmitter among the

The unit stores 13 groups of selectable channels:
groups 00 (102 channels), 11 (12 channels), 12 (9 channels),
13 (9 channels), A1 (8 channels), A2 (6 channels),
A3 (6 channels), L1 (6 channels), L2 (6 channels),
M1 (6 channels), M2 (5 channels), H1 (8 channels) and
H2 (8 channels).
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.
Each “wireless channel” is represented by a 2-digit TV
channel number and a 2-digit number, for example: 66-23.
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 m (330
feet)1) apart as far as they are installed within sight of each
other.
1) The distance depends on the operating environment and conditions.
