Precautions

On operation

• The tuner must be used within a temperature range of
0°C to 40°C. 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.

• 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.

3

Press the CH button on the first tuner unit and hold
it down for 3 seconds.

The first tuner unit searches for available channels
in the selected group, and available channels in the
group are so assigned to all tuner units
automatically that two or more tuner units may not
use the same channel.
After automatic setting, you can adjust the groups
and channels of individual tuner units.

Notes

• Do not use group 00.

• If no channels are available,

“NO CH” is displayed

and channel setting is aborted.

When using two MB-806A Base Units

When you use two base units, proceed as follows to
ensure that the two tuner units do not use the same
channel settings.

1

Follow the procedure explained above to set the
group and channel of the first base unit.

2

Power on the wireless microphones or transmitters
after adjusting them to the channels of each tuner
unit.

Note

If the microphones or transmitters are not powered
on, the two tuner units may use the same channel
twice.

3

On the first tuner unit of the second base unit, set
the same group as selected on the first base unit.

4

Press the CH button of the first tuner unit on the
second base unit and hold it down for 3 seconds.

Available channels in the same group (channels
not used by the first base unit) are automatically
set on the first tuner unit and the other tuner units
on the second base unit.

Note

If automatic channel setting dose not function well for
the second base unit (due to poor reception), set
channels manually for the second base unit.

Set the reception channel.

For details on setting the channels on the tuner, see
“Channel Setting” on page 8.

3

Turn on the wireless microphone or transmitter.
Use the wireless microphone or transmitter to
which the same channel is assigned as to the tuner.

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 and transmitter. Then select a
channel at 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.

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.

• Separate the reception antennas and the transmitter by
more than 3 meters.

• 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

1)

apart as far as they are installed within sight

of each other.

1) The distance depends on the operating environment and
conditions.

Muting Functions

This tuner has the following three muting functions,
which work in combination.

(1) Muting 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 can be muted when the
RF input level falls below the muting level.

(2) Tone squelch

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

(3) Noise squelch

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

To turn off the muting functions

While holding down the GP and CH buttons, turn the
POWER switch to ON. All indications momentarily
appear, then go off.

“OFF” is then displayed. This
procedure cancels all three muting functions at the
same time.

To turn on the muting functions

Turn the POWER switch to OFF, then to ON again.
The three muting functions are activated at the same
time.

“NO TONE” message appears when you turn off the AF switch,
but this is normal.

Apart from the normal indications, the following error
messages may appear on the display.

Guidance on use of multi-channel system

This product is designed to give excellent interference
free operation in multi-channel systems. To maintain
this, Sony recommends that one of the original Sony
groups, number 01, 02, 03, 04, 13, L1, L2, M1 or M2
is selected.
These groups will offer excellent performance free
from mutual interference from other Sony wireless
microphone transmitters in the selected group when
used under the recommended operating conditions.
The remaining groups are included for compliance
with frequency regulations in various countries, and
will not always guarantee interference free operation.
Group 00 is used to scan for open channels, or to use
only for a one channel system.

Richtlinien für ein Mehrkanalsystem

Dieses Produkt wurde im Hinblick auf hervorragenden
interferenzfreien Betrieb in Mehrkanalsystemen
entwickelt. Deshalb empfehlen wir, eine der Sony­Kanalgruppen.
Nummer 01, 02, 03, 04, 13, L1, L2, M1 oder M2
auszuwählen.
Bei diesen Gruppen erzielen Sie eine au

ßerordentliche
Leistung ohne gegenseitige interferenzen durch andere
schnurlose Mikrofonsender von Sony in der
ausgewählten Gruppe, vorausgesetzt, die empfohlenen
Betriebsbedingungen werden eingehalten. Bei den
übrigen Gruppen gelten die Frequenzbestimmungen in
verschiedenen Ländern, und ein interferenzfreier
Betrieb kann nicht immer gew

ährleistet werden.

Gruppe 00 dient zum Durchsuchen offener Kan

äle

bzw. eignet sich f

ür ein Einkanalsystem.

English

Overview

The WRU-806A is a reliable UHF synthesized tuner unit for the 800­MHz-band Sony UHF wireless microphone system which uses the
frequency bands allocated for UHF TV broadcasting. To use this unit,
install it in a Sony MB-806A Tuner Base Unit.
The unit is designed to enable simultaneous use of multiple channels
when channels are selected according to the Sony channel plan.
In building up a UHF wireless microphone system, be sure to combine
a microphone/transmitter and a tuner having the same TV channel
number (62 or 69).
The following are the principal features of this unit.

Phase Locked Loop (PLL) synthesized system

The unit has a refined phase locked loop (PLL) synthesizer circuit.

Preprogrammed wireless channel plan for simultaneous
multichannel operation

The unit has many preprogrammed, easily settable channels in a
simultaneous multichannel operation.

Versatile display

A liquid-crystal display provides a variety of information, including
the levels of the reception channels, RF information and transmitter
battery alarm.

Space diversity reception system

The unit 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 unit is in signal reception standby mode.

Compander system

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

System Configuration

The unit can be used with a UHF Synthesized Wireless Microphone or
UHF Synthesized Transmitter among the models listed in the table
below.

Precaution

On operation

• The unit must be used within a temperature range of 0°C to 40°C.

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.

• 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 noise or 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.

Overview

The WRU-806A is a reliable UHF synthesized tuner unit for the 800­MHz-band Sony UHF wireless microphone system which uses the
frequency bands allocated for UHF TV broadcasting. To use this unit,
install it in a Sony MB-806A Tuner Base Unit.
The unit is designed to enable simultaneous use of multiple channels
when channels are selected according to the Sony channel plan.
The following are the principal features of this unit.

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 102 channels over a 14­MHz frequency.

Preprogrammed wireless channel plan for simultaneous
multichannel operation

The unit 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 unit 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 unit is in signal reception standby mode.

Compander system

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

System Configuration

The unit can be used with a UHF Synthesized Wireless Microphone or
UHF Synthesized Transmitter among the models listed in the table
below.

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 noise or 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,

For removing a WRU-806A, see “Installing a WRU-806A Tuner Unit” on page 1-5.

2-5-2. WRU-806A Checking

The following procedures describe how to prove WRU-806A (repair unit) whether it needs to be repaired or not.

Equipment Required : MB-806A (quality unit)

WRU-806A (quality unit)

(1) Install the repair WRU-806A to be examined in a quality MB-806A.
(2) Check the fault with a quality MB-806A.

. If there is a fault, WRU-806A (repair unit) is defective.

Check the WRU-806A then fix a faulty section, and perform “3. Electrical Alignment”.

. If there is no fault found on the MB-806A, repairing WRU-806A is no longer defective. Thus the repairing MB-

806A, other than WRU-806A, is defective.

2-6. Unleaded Solder

Boards requiring use of unleaded solder are printed with a lead free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)

: LEAD FREE MARK

m
. Be sure to use the unleaded solder for the printed circuit board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is recommended to

use the soldering iron having a temperature regulator.

. The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly longer time. The

printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful.
