Precautions

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 tuner must be used within a temperature range of

0°C to 40°C (32°F to 104°F). Avoid using the tuner

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 tuner 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 tuner.

•To avoid degradation of the signal-to-noise ratio, do

not use the tuner 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

tuner

•Switching lights on or off may produce electrical

interference over the entire frequency range. Position

the tuner and the wireless microphones so that

interference is minimized.

•The tuner is precisely adjusted at the factory and no

adjustment before use is necessary. Do not touch the

inside of the tuner or try to repair it by yourself.

On cleaning

Clean the tuner with a dry, soft cloth. Never use

thinner, benzene, alcohol or any other chemicals, since

these may damage the finish.

Overview

Space diversity reception system

The WRR-801A 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-801A is in signal

reception standby mode.

Compander system

A compander (compressor/expander) system enables

stabilized wireless transmission over a wide dynamic

range.

Rack mounting

The WRR-801A can be mounted in an EIA standard

19-inch rack (1U size).

System Configuration

The tuner 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

Overview

The WRR-801A 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 tuner is designed to enable simultaneous use of

multiple channels when channels are selected

according to the Sony channel plan.

Installing six WRU-801A UHF Synthesized Tuner

Units will enable six-channel operation on the tuner.

At shipping, one tuner unit is installed in the tuner, and

additional tuner units (sold separately) can be installed

easilly.

Features

Phase Locked Loop (PLL) synthesized

system

The WRR-801A 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-801A has many preprogrammed, easily

settable channels for simultaneous multichannel

operation. One group allows setting of 102 channels.

The tuner 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.

Modular multichannel reception

By installing optional WRU-801A UHF Synthesized

Tuner Units, you can receive up to six channels on one

WRR-801A unit.

Versatile display

A liquid-crystal display provides a variety of

information, including the levels of the reception

channels, RF information and transmitter battery

condition.

Wirelss Channels Selectable

The tuner stores thirteen 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.

Wireless Channel Lists

Group 00: All channel access

Use only for a one-channel system or to scan for open

channels.

Up to five WRU-801A UHF Synthesized Tuner Units

can be installed.

Notes

•Be sure to power this unit off before installing the

WRU-801A.

•The buttons and display on the front panel of the

WRU-801A may be damaged if they are gripped too

strongly. Always hold the WRU-801A by the side.

•Do not touch the connectors on the rear panel of the

WRU-801A.

•Be careful of static electricity.

Installing a WRU-801A

1Power the tuner off and remove the blank panel

with a screwdriver or other tool.

2Hold the WRU-801A by the side and insert into

the slot. Push in until you hear a click.

Installing aWRU-801ATuner Unit

Removing a WRU-801A

On the bottom panel of the tuner, locate the lever

corresponding to the slot where the WRU-801A is

installed and pull the lever forward. The WRU-801A is

ejected from the slot.
