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 thinner 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-805A is a transmitter to be used in combination
with the WRR-800A/801A UHF Synthesized Diversity
Tuner for an 800 MHz band UHF synthesized wireless
microphone system for broadcast or movie production
purpose.
The WRT-805A can also be used in conventional Sony
Wireless Microphone System composed of the WRT-810A/
820A UHF Synthesized Transmitter, the WRR-810A/820A/
840A/850A UHF Synthesized Diversity Tuner, etc.
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
A 12 MHz frequency band (or two consecutive-numbered
TV channels, such as 68 and 69 of the WRT-805A) is
assigned to each microphone/transmitter and tuner model.
In building up a UHF wireless microphone system, be sure
to combine a microphone/transmitter and a tuner having the
same TV channel number.
Features
Easy selection of 94 channels
The unit can operate on any one of 94 carrier frequencies
selected by a simple button operation.
Compact and lightweight
Innovative high-density mounting technology has enabled
the creation of this compact and lightweight transmitter,
which lets you move anywhere for Electronic News
Gathering (ENG) and Electronic Field Production (EFP).
The curved design of the moulded case allows a comfortable
fit to your waist.
Battery status information
This transmitter has capability of transmitting “Battery
status information” to the WRR-800A/801A/850A to give
advance warning of battery depletion.
The information is sent to the WRR-800A/801A/850A in
approx. 1 hour advance to battery exhaust so that they can
safely replace battery of the transmitter.
When the WRR-800A/801A/850A receives the information,
the LED and the LCD on the panel start flashing.
Operation powered by easily available battery
The built-in high-efficiency DC-DC converter allows stable
operation, for about 6 hours continuously, with just a single
LR6 (size AA) alkaline battery.
4
LCD for coordinated operation control
The LCD shows the current channel number, the residual
battery power, input attenuation setting, AF input level and
RF output.
An accumulated operation time indication is also provided
for simple control of the time of battery use (in 1-minute
increments).
Saved channel and input attenuation settings
The unit stores the channel and the input attenuation setting
when it is turned off. The saved settings are retained even if
the battery is removed. Therefore, when using the unit next
time, you need not make the same settings again.
Highly reliable electronic attenuator
The built-in input level attenuator is adjustable in a range of
0 to 21 dB in 3-dB steps. It reduces signal distortion when
an excessively strong audio signal is inputted.
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.
Audio input connector (3.5-mm dia.) with locking
mechanism
The screw-type locking mechanism ensures reliable
connection.
Compact helical antenna

Channels and Carrier Frequencies
The WRT-805A can transmit on any selected wireless
channel among those listed below.

When the battery reaches stage 3 shown in the table, the
BATT indication on the WRR-800A/801A/850A also starts
flashing.
Promptly replace the battery when the indications flash.
Note
The indication may be incorrect if the battery is not new
when inserted. If you plan to use the transmitter for a long
period, it is best to replace the battery with new one.
Notes on battery
Use a new alkaline battery.
•
Be careful to insert the battery with the correct polarity.
•
When not using the transmitter for a long period, remove the
•
battery to avoid leakage. If the battery does leak, clean all
leakage from the unit and insert a new battery. Leakage left
in the unit may cause poor battery contact. If there seems to
be poor battery contact, consult your Sony dealer.

To obtain the proper output level
The optimum level setting depends on type of guitar. Set the
INPUT level switch and the ATT (attenuator) level of this unit
according to the guitar to be used.
Loud noise: If noise is not negligible even if the INPUT
switch is set at “–40 dBV” and the ATT level is “0 dB,” set
the INPUT switch to “–60 dBV” and adjust the ATT level
for an optimum result.
Distortion: If the guitar sound is distorted even if the
INPUT switch is set at “–40 dBV” and the ATT level is “0
dB,” increase the ATT level by 3 dB (0 to 3 to 6 . . . 21 dB).
For the ATT level adjustment, see page 13.

System Operation
To operate with 2 or more channels, maintain a distance of
•
at least 30 cm (1 ft.) between each pair of transmitters.
For details of operation with 2 or more channels, refer to
the Operating Instructions for the WRR-800A/801A UHF
Synthesized Diversity Tuners.
Ensure that the tuners set to channels not being used are
•
either turned off or set to the minimum output level.
When powering the transmitter on or off, to keep the noise
•
to a minimum, set the audio output level from the tuner or
mixer to a minimum.
Powering the transmitter on without checking the channel
•
selection first may interfere with the operation of other
microphones/transmitters, if the current setting is already
being used.
Separate the reception antennas and the transmitter by more
•
than 3 meters (10 ft.).
Settings
Initiating Setting Mode
In Setting mode, you can change the transmission channel
and the attenuation level, or reset the accumulated time
indication.
To enter Setting mode
While holding down the SET button, set the POWER switch
to ON.
Hold the SET button down until a display appears on the
liquid-crystal display.
The transmitter enters Setting mode and the indication
before the transmitter was previously turned OFF flashes on
the liquid-crystal display.
Each time you press the SET button, Channel selection
mode, Attenuator adjustment mode (page 14) and
Accumulated time indication reset mode (page 15) are
cyclically switched.

selected on the tuner used in the same system.
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 a tuner with the 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
