Features

The WRR-850A is a high-performance tuner for the 800-MHz-band Sony
UHF wireless microphone system which uses the frequency bands
allocated for UHF TV broadcasting. This tuner enables application of
multiple channels over unused television channels through the use of the
built-in Sony original channel plan.

Phase Locked Loop (PLL) synthesized system

The unit has a refined phase locked loop (PLL) synthesizer circuit and
covers two UHF TV channels. It operates on 94 channels over a 12-MHz
frequency.

Built-in wireless channel plan for simultaneous
multichannel operation

The WRR-850A has many preprogrammed, easily settable channels in a
simultaneous multichannel operation. One group allows setting of 94
channels. The unit also has six preset groups of channels, each of which
permits simultaneous operation of 8, 11, 13, or 19 channels without the
effects of intermodulation. There is also a channel plan for 42 channel
simultaneous operation using the 6 TV bands on UHF TV channels 64 to

69.

Twin tuners

The WRR-850A has two tuner units. You can set the tuners to different
channels and still operate both at the same time.

Versatile display

A large 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-850A provides stable signal reception with minimum dropout.

Adjustable muting level

You can select the muting level (15 dBµ, 25 dBµ and 35 dBµ) to meet your
specific needs.

Tone squelch circuit for noise elimination

A built-in squelch circuit eliminates noise and signal interference when the
unit is in signal reception standby mode.

Compander system

A compander (compressor/expander) system enables stabilized wireless
transmission over a wide dynamic range.

Output monitoring

You can monitor the audio output using headphones. The level is
adjustable.

1U-size EIA rack mount

4

The unit can be mounted in an EIA-standard 19-inch rack (1U size).

Channel Plan

Groups, Channels and Frequencies

The unit stores 11 groups of selectable channels: groups 00
(94 channels), 11 (11 ch.), 12 (8 ch.), 13 (8 ch.), A1 (19 ch.),
A2 (13 ch.), A3 (13 ch.), L1 (7 ch.), L2 (7 ch.), H1 (7 ch.),
and H2 (7 ch.). 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.
The following pages explain the purpose of each group, and
give the channel-frequency assignment table for each group.

Group 00 (to receive all 94 channels)

This group receives all 94 wireless microphone channels
selected at 125-kHz intervals in a frequency band assigned
to a WRR-850A combination.

Note

When using more than one channel from group 00

Notes

• Each “wireless channel” is represented by a 2-digit TV
channel number and a 2-digit number, for example: 68-23.

• The channels in each group other than group 00 can be
used simultaneously.

• 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.)

• If there is a TV broadcasting station nearby, to avoid
possible interference with 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.

simultaneously, avoid selecting adjacent channels or
channels at uniform intervals.

Precautions

• The tuner must be used within a temperature range of 0°C to +50°C
(+32°F to +122°F). Avoid using the unit for extended periods at
extremely high temperatures or placing it in direct sunlight, as 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.

• If you install the tuner in a rack, be sure that the rack is adequately
ventilated; inadequate rack ventilation may lead to overheating
problems.

• If the tuner is used in an environment that is humid, dusty or susceptible
to harmful gas, clean the connectors and the surface after use. If used in
such an environment for an extended period, the tuner life may be
shortened.

• Do not install the tuner near electrical equipment, such as motors,
transformers, or dimmers, since this may incur magnetic induction.

• Switching lights on or off may produce electrical interference over the
wider frequency range. Position the tuner and the wireless microphones
so that interference is minimized.

• To avoid degradation of the signal-to-noise ratio, do not use the tuner in
noisy places or in locations subject to noise or vibration, such as the
following:
— near electrical equipment, such as motors or transformers
— 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

Install the tuner as far as possible from sources of interference and, if

needed, provide shock absorbent material.

• Clean the tuner with a dry, soft cloth. Never use thinner, benzene,
alcohol or any other chemicals, since these may damage the finish.

Notes on Antenna Installation

• Use a pair of antennas. Separate them by 1 to 2

1

meters (3

/3 to 6 2/3 feet). Mount the antennas so that
a wireless microphone or transmitter can transmit
signals directly to the antennas.

• Do not install the antennas in the following
locations:
– inside the ceiling or walls
– near windows, metal boards, or electric equipment

(lighting fixtures, motors, elevators, breakers, etc.)
electronic equipment (computers, dimmers,
televisions, TV cameras, etc.)

– where people or other equipment might interfere

with them

Separate the antennas by 1 to 2
meters (3 1/3 to 6 2/3 feet).

• The recommended coaxial cable for connecting the
antennas to the tuner and antenna divider is a 5D-2V
(50 ohm or higher). You can also use a 5C-2V (75
ohm or higher).
Signal loss: 5D-2V 50 m: 12.5 dB

100 m: 25 dB

5C-2V 50 m: 13.5 dB

100 m: 27 dB

• The coaxial cable should be as short as possible. The
signal loss increases as the cable length increases,
which has a greater impact than the difference
between 50 ohms and 75 ohms.

Mount the antennas more than 10 centimeters
(4 in.) away from the ceiling or an adjacent wall.

Mount the antennas about half way
between the floor and the ceiling or
at about 5 meters (16 ft. 8 in.) in
height.

Mount the antennas as far as
possible from windows to prevent
interference from outside.

Mount the antennas as far as
possible from electric equipment
(e.g., elevators, computers, etc.) to
prevent radio wave interference.

Channel scan function

Before using the wireless microphones, you should use the channel scan
function to check for interference and the frequencies of channels that are
already in use, so that they may be avoided when selecting groups and
channels.

To activate this function, select the group you wish to scan and press the
CH, the plus (+) and the minus (–) buttons simultaneously. The reception
channels within the selected group will be scanned automatically.

The RF lamp lights up whenever signals above 15dB µ are detected in the
frequencies within the wireless channels receivable on Sony receivers. The
scanning will also stop on any frequency containing a tone signal of

32.768kHz, provided the RF signal is stronger than the set muting level.

Whenever the scanning stops on a particular frequency, that particular
frequency is being used.

To restart the scanning process after it has stopped on a particular
frequency, press the CH, the plus (+) and the minus (–) buttons
simultaneously.

Notes

• Once the channels in a group have been scanned twice, the scanning stops
automatically. If you want to stop the scanning process, press any button.

• If the interference is very strong, the scanning may stop on a frequency
that differs from the actual interference frequency.

Muting functions

26

The WRR-850A has the following three muting/squelching functions:

(1) Weak RF level muting

The weak RF level muting function mutes the audio output so that the
transmission can avoid affection by noise due to weak radio signal
when the field strength falls below the set level. Levels are selectable
among 15, 25 and 35 dBµ. 15 dBµ muting level is normally
recommended. The higher muting set level can suppress interference
caused by undesired RF carriers coming over from the surrounding
place. This will, however, result in a shorter range of reception.
When audio output is necessary more than good S/N, it is
recommended to use WRR-850A with the muting functions off. When
the RF level muting function is switched off, the noise squelching
function switches off automatically as well.

(2) Tone signal squelching

The tone signal squelch function mutes the audio output unless the RF
carrier contains the tone signal (32.768kHz) for discrimination of the
Sony wireless microphone system. The moment a transmitter is turned
on or off, it does not transmit the tone signal on the RF carrier, and
this function enables the WRR-850A to squelch noise caused when a
transmitter is switched on or off. It is possible to operate the WRR­850A together with a transmitter which has no tone signal if the tone
signal squelch circuit is turned off. While the tone signal squelch
circuit is off, be aware that the noise generated by power switch-on/off
of a transmitter will not be squelched.
Once the tone signal squelch circuit is turned off, it remains off even
after the tuner is switched off.

(3) Noise squelching

When RF level from a transmitter is too weak to produce a quality
audio signal, the noise squelching function checks if noise exists in the
detected audio signals, and the function will shut off the audio output if
noise exists. In most cases, the noise squelch function should be left on.

Notes

• If any of the muting/squelching functions are switched off, the indicator

appears in the muting display. If

OFF

OFF

appears in the muting
display, you can confirm which muting/squelching function has been
turned off by pressing the buttons indicated in the “Buttons” column in
the “Error Messages” table on page 32.

• Under normal circumstances, all three muting/squelching functions
should be left on. If you find that one of the muting/squelching functions
has been turned off by accident, turn it back on again as described below,
and in the “Remedy” column of the “Error Messages” table on page 32.

Note

Press the POWER switch after reducing the volume of equipment
connected to the TUNER OUTPUT as noise will be heard if the power
is turned on or off beforehand.

2 Turn on the wireless microphones or transmitters.

• Before using the wireless microphones or the transmitter channels, set
the microphones to the same channels as those on the tuner.

• For details on setting the channels on the tuner and setting up the
system, see “Channel Plan” on page 5 and System Setup on pages
18~21.

• For details on channel selection, see “Selecting the Reception
Channel” on page 22.

If noise is heard

Depending on the environment where the system is installed, outside noise
or radio waves may disrupt the transmission of certain channels.
To select a channel under these circumstances, switch channels after
turning off the power to the microphone or transmitter, then select a
channel for which the RF indicator is off (i.e., a channel free from noise or
radio wave interference). Then set the microphone and transmitter to the
same channel.

28

For better reception

The RF lamp remains on when reception is good. If the RF lamp is off,
check that there are no interfering objects between the wireless
microphones/transmitters and the antenna, and that they are within range
of reception.

• For details, see “Installation” on page 16.

Notes

• You can use a maximum of two wireless microphones or transmitters
with this tuner. When setting channels for such equipment, you must set
each piece of equipment to a different channel within the same group.
For example, in group 11, channels 68-05 and 68-14 can be selected but
channels 68-05 and 68-11 cannot. If only one of the two tuners is in use,
be sure to set them to different channels within the same group.

• Be sure to separate the transmitter and the reception antenna by more
than two meters (6 feet, 8 inches). If they are closer than two meters (6
feet, 8 inches), the tuner may operate erratically and generate noise.
