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.

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

models listed in the table below.

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.
