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.
Transmitting Channel Band
The microphone/transmitter and tuners of the wireless
microphone system are classified by frequency band.
A 14-MHz frequency band (or two consecutive-numbered
TV channels, such as 62 and 63 of the WRT-805A/CE62
model) or an 8-MHz frequency band (or TV channel 69 and
UK General Use) is assigned to each microphone/transmitter
and tuner model.
In building a UHF wireless microphone system, be sure to
combine a microphone/transmitter and a tuner having the
same TV channel number.
CE62 model
A 14-MHz frequency band is assigned to the WRT-805A/
CE62 model, permitting it to operate on any of 111 carrier
frequencies in 125-kHz steps of Sony original channel plan
or 561 carrier frequencies in 25-kHz steps of German User
Groups in the range of TV channels 62 and 63.
CE69 model
An 8-MHz frequency band is assigned to the WRT-805A/
CE69 model, permitting it to operate on any of 64 carrier
frequencies in 125-kHz steps of Sony original channel plan
in the range of TV channel 69 or 14 carrier frequencies in
25-kHz steps of UK General Use.
For the selectable wireless channels and frequencies, see
“Wireless Channel Lists.”

Features
Phase Locked Loop (PLL) synthesized system
The WRT-805A has a refined phase locked loop (PLL)
systhesizer circuit.
Preprogrammed wireless channel plans for simultaneous
multichannel operation
The WRT-805A has many preprogrammed channel groups,
meaning combination of wirelss channels to permit
simultanous operation of multiple channels without
intermodulation.
Any available group and channel can be selected with 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.
Remote battery alarm on tuner
This transmitter has capability of transmitting “Battery
status information” to the WRR-800A/801A to give advance
warning of battery depletion.
The information is sent to the WRR-800A/801A in approx.
1 hour advance to battery exhaust so that they can safely
replace battery of the transmitter.
When the WRR-800A/801A 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.
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.

4
EN
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.
