Precautions

•The unit is designed for use in ambient temperature range

of 0°C to 50°C (32°F to 122°F).

•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 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.

•The unit has been factory adjusted precisely. Do not

tamper with its internal parts or attempt to repair it.

Introduction

The WRT-800A is a wireless microphone to be used in

combination with the WRR-800A/801A UHF Synthesized

Diversity Tuner for an 800-MHz band UHF synthesized

wireless microphone system.

Transmitting Channel Band

The microphone/transmitter and tuners of the wireless

microphone system are classified by frequency band.

A 14-MHz frequency band (or two consecutive-numbered

TV channels, such as 62 and 63 of the WRT-800A/CE62

model) or an 8-MHz frequency band (or TV channel 69 and

UK General Use) is assigned to each microphone/transmitter

and tuner model.

In building a UHF wireless microphone system, be sure to

combine a microphone/transmitter and a tuner having the

same TV channel number.

CE62 model

A 14-MHz frequency band is assigned to the WRT-800A/

CE62 model, permitting it to operate on any of 111 carrier

frequencies in 125-kHz steps of Sony original channel plan

or 561 carrier frequencies in 25-kHz steps of German User

Groups in the range of TV channels 62 and 63.

CE64 model

A 14-MHz frequency band is assigned to the WRT-800A/

CE64 model, permitting it to operate on any of 111 carrier

frequencies in 125-kHz steps of Sony original channel plan

or 561 carrier frequencies in 25-kHz steps of German User

Groups, in the range of TV channels 64 and 65.

CE69 model

An 8-MHz frequency band is assigned to the WRT-800A/

CE69 model, permitting it to operate on any of 64 carrier

frequencies in 125-kHz steps of Sony original channel plan

in the range of TV channel 69 or 14 carrier frequencies in

25-kHz steps of UK General Use.

For the selectable wireless channels and frequencies, see

“Wireless Channel Lists.”

Features

Phase Locked Loop (PLL) synthesized system

The WRT-800A has a refined phase-locked loop (PLL)

systhesizer circuit.

Easy channel selection

Any available transmitting channel can be selected with

simple switch settings.

Operation powered by easily available battery

The built-in high-efficiency DC-DC converter allows stable

operation, for about 12 hours continuously, with just a single

LR6 (size AA) alkaline battery.

Remote battery alarm on tuner

This microphone has capability of transmitting “Battery

status information” to the WRR-800A/801A to give advance

warning of battery depletion.

The information is sent to the WRR-800A/801A in approx.

1 hour advance to battery exhaust so that they can safely

replace battery of the microphone.

When the WRR-800A/801A receives the information, the

LED and the LCD on the panel start flashing.

RF carrier with tone signal

The unit transmits the RF carrier accompanied by a tone

signal, enabling the tuner with a tone squelch circuit to take

out only the target audio signal received.

Wide dynamic range and low noise

The compander (compressor/expander) system enables

transmission over a wide dynamic range with minimum

noise.

Compact helical antenna

Parts Identification

1Power indicator

Lights when the power of the wireless microphone is turned

ON. Promptly replace the battery if the indicator does not

light even when you turn the power on.

2Power switch

Turns the power of the wireless microphone ON or OFF.

3Channel select switches

For setting the transmitting channel.

The CE62 and CE64 models have one slide and three rotary

switches and the CE69 model has one slide and two rotary

switches.

For examples of channel setting, see pages 6 to 8.

Battery indication

When you turn the power on, the power indicator lights.

When the battery level becomes low, the indicator goes off

as a warning. Promptly replace the battery if the power

indicator does not light when you turn the power on.

•The BATT indication on the WRR-800A/801A starts

flashing in synchronization when the power indicator of

this wireless microphone goes off.

Notes on battery

•Use a new alkaline battery, and check the recommended

“useby” date on the bottom of the battery.

•Be careful to insert the battery with the correct polarity.

•When not using the wireless microphone for a long period,

remove the battery to avoid leakage. If a battery does leak,

clean all leakage from the unit and insert new battery.

Leakage left in the unit may cause poor battery contact. If

there seems to be poor battery contact, consult your Sony

dealer.

Power Supply

The microphone can operate on one LR6 (size AA) alkaline

battery continuously for about 12 hours at 25°C (77°F).

Inserting the batteries

1Rotate the grip counterclockwise and slide it down.

Note

The grip may separate from the body. Becareful not to drop it.

2Match the polarity and insert the battery.

Channel Setting

Set the channel select switches for the desired wireless

channel using the supplied screwdriver.

Notes

•Turn off the microphone when setting the transmitting

channel to eliminate interference or noise on other wireless

equipment.

If the channel select switches are operated while the

microphone is on, the power indicator flashes as a

warning.

•If you set to any channel other than those listed in

“Wireless Channel Lists,” the power indicator flashes as a

warning.

•The microphone does not transmit while the power

indicator is flashing.
