Overview
The WRR-805A is a highly reliable portable tuner for the
800 MHz band 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).
Features
Phase Locked Loop (PLL) synthesized system
The WRR-805A has a refined phase locked loop (PLL)
synthesizer circuit.
Preprogrammed wireless channel plans for simultaneous
multi channel operation
The WRR-805A has many preprogrammed channel groups,
meaning combination of wireless channels to permit
simultaneous operation of multiple channels without
intermodulation.
Any available group and channel can be selected with a
simple button operation.
Compact and lightweight
Mounting technology and the versatile soft case enable this
compact and lightweight tuner, which lets you move
anywhere for Electronic News Gathering (ENG) and
Electronic Field Production (EFP).
Remote battery alarm from transmitter
This tuner has capability of receiving “Battery status
information” from the transmitter WRT-805A/822A to
make advance warning of battery depletion.
The information is sent in approx. one hour advance to
battery exhaust so that you can safely replace the batteries of
the transmitter.
Operation powered by easily available batteries
The built-in high efficiency DC-DC converter allows stable
operation, for about 6 hours continuously, with two LR6
(size AA) alkaline batteries.
LCD for coordinated operation control
The built-in CPU controls operation of the unit, including
the PLL circuit function. The LCD shows the current
channel number/frequency, the residual battery power, AF
output level and RF input level.
An accumulated operation time indication is also provided for
simple control of the time of battery use (in one-minute
increments).
Saved channel setting
The unit stores the channel setting when it is turned off. The
saved settings are retained even if the batteries are removed.
Therefore, when using the unit next time, you need not
make the same settings again.

Overview
a)
Wireless Channels Selectable
Note
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
11, 12, 13, A1, A2, A3, L1, L2, M1, M2, H1 or H2 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.
Group 00 is used to scan for open channels, or to use only
for a one channel system.
Each “wireless channel” is represented by a 2-digit TV
channel number followed by another 2-digit number, for
example: 66-01.
Wide dynamic range
The compander (compressor expander) system enables
stable reception over a wide dynamic range.
Output monitoring
The audio output can be monitored through headphones
(either of stereo or monaural). The monitoring level is
adjustable.
Muting switch for noise elimination
System Configuration
The WRR-805A can be used with the WRT-805A/820A/
822A/860A UHF synthesized transmitter or the WRT-810A/
830A/867A UHF synthesized wireless microphone.
Sony 800 MHz band system models
a) For this models, the AN-820A UHF antenna and the WD-820A UHF
antenna divider are required.

Group 00: All channel access
Use to scan for open channels.
Use only for a one channel system.

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.
