Overview

The WRR-862A/862B is a highly reliable diversity tuner for the Sony UHF wireless microphone system to be used for broadcast or movie production purposes.

This tuner is suitable for Electronic News Gathering (ENG) and Electronic Field Production (EFP).

The microphone/transmitter and tuners of the wireless microphone system are classified by frequency band.

In building a UHF wireless microphone system, be sure to combine a microphone/transmitter and a tuner having the same wireless channel (frequency).

Features

Dual Diversity Tuner

Despite of its compact design, the WRR-862A/862B simultaneously receives two signal channels. A space diversity system is employed on both channels to eliminate signal dropout and provide stable reception. Two SMC9-4S (Sony 4 pin) audio output connectors are provided on the top panel.

Wide Operating Frequency ranges

The WRR-862A operates over a 14 MHz frequency band within the range of 792 MHz to 806 MHz (model available in Australia) , while the WRR-862B operates over a 24 MHz frequency band between 470 MHz to 806 MHz (model available in U.S.A.), or 470 MHz to 862 MHz (model available in Europe).

WRR-862A

Model available in Australia: 792 to 806 MHz, TV channels 66 to 67 WRR-862B

Model available in USA: 470 to 806 MHz, TV channels 14 to 69 (14 frequency band, divided into 24 MHz range. All 14 frequency bands may not be available in some areas.)

Model available in Europe: 470 to 862 MHz, TV channels 21 to 69 (17 frequency band, divided into 24 MHz range. All 17 frequency bands may not be available in some areas.)

Compact, lightweight and easy to mount on Sony camcorders

The WRR-862A/862B is extremely compact and lightweight, housing in the rugged, die-cast magnesium case. It is easily mounted on Sony camcorders.

Preprogrammed wireless channel plans for simultaneous multi channel operation

The WRR-862A/862B has many preprogrammed channel groups, meaning combination of wireless channels to permit simultaneous operation of multiple channels without intermodulation.

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

9 (GB)

Settings

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.

Notes

•Do not remove the batteries during group and wireless channel selection. If they are inadvertently removed, reinsert them immediately and repeat the steps on pages 7 to 9 from the beginning.

•Make sure that the channel selected is the same as that selected on the transmitter used in the same system.

•Be sure to set tuners 1 and 2 to different channels.

•Depending on the noise or interference conditions, the selectable channels may not necessarily all be usable. If necessary, you can determine the usable channels by stepping the channel selection through a number of channels on the tuner with the microphone/transmitter set to OFF. Those channels on which the RF indicator of the tuner does not light are usable.

•If there is a TV broadcasting station near by, do not use the station's channel.

•The unit may not operate correctly if it is turned on again immediately after turning off the power while in setting mode. Pause for a few seconds or more before turning on the power again.

•When operating the unit with one transmitter (for example, using tuner 1 for reception, and leaving tuner 2 unused), noise or audio signals may occur on the unused tuner, if the tuner and the transmitter are too close to each

other. In such a case, keep a enough distance to ensure the proper performance of the unit.

•When operating two or more UHF wireless microphone systems using channels in different groups, ensure that the systems are at least 100 m (330 feet) apart from each other. (The same applies also when using channels in a group if the different UHF wireless microphone systems are installed where they are within sight of each other.)

Setting the Squelch Level

You can eliminate the noise and signal interference which may occur in reception stand-by mode. Select a squelch level from 5 dBµ, 10 dBµ or 15 dBµ. The factory preset level is 10 dBµ. To obtain a wide service area, set this to 5 dBµ. When using the tuner in a multi-channel system or

when you want to receive noise free audio input all the time, set it to 15 dBµ.

1 Press the MODE button until the squelch level appears.

2 Press the SET button.

The squelch level indication starts flashing.

Squelch level

3 Press the + or – button to select the desired level.

4 When the desired level appears, press the SET button. The display stops flashing and the selected level is now stored in memory.

Squelch functions

When the SQUELCH switch is set to ON, the following functions work in combination.

(1) Squelching by RF input level

As sufficient S/N for the audio output may not be obtained if no RF signal is received or the RF input level is low, the audio output is squelched when the RF input level falls below the squelch level selected.

(2) Tone squelch

The audio output is obtained only when the unit receives an RF signal which includes a specified tone signal. The audio output is squelched to eliminate noise which may be heard when the transmitter is turned on/off or the unit receives an interference RF signal.

(3) Noise squelch

The audio output is squelched to eliminate noise which may be heard when there is such excessive interference RF signal that the tone squelch does not work.

Resetting the Accumulated Time Indication

The time indication accumulates time in hours and minutes when the WRR-862A/862B is on.

Reset the indication to “00:00” whenever you replace the batteries so that it can display the running time of the batteries.
