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.

5
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

Información sobre el estado de la pila
Este transmisor posee la capacidad de poder transmitir
“información sobre el estado de la pila” al WRR-800A/
801A/850A para ofrecerle un aviso anticipado del
agotamiento de la pila.
Cuando el WRR-800A/801A/850A reciba la informción, el
LED y el visualizador de cristal líquido del panel
comenzarán a parpadear.

Alimentación fácil con pila
El convertidor de CC-CC de gran eficacia incorporado
permite la operación estable, durante 6 horas continuas, con
una sola pila LR6 (tamaño AA).
Visualizador de cristal líquido para el control
coordinado de la operación
El visualizador de cristal líquido mostrará el número del
canal actual, la energía restante de la pila, el ajuste de la
atenuación de entrada, el nivel de entrada de AF, y la salida
de RF.
También existe una indicación de tiempo de operación
acumulado para poder controlar fácilmente la utilización de
la pila (en incrementos de 1 minuto).
Ajustes de canal almacenado y atenuación de entrada
La unidad conservará los ajustes de canal y de la atenuación
de entrada aunque desconecte su alimentación. Los ajustes
almacenados se conservará incluso aunque extraiga la pila.
Por lo tanto, cuando vuelva a utilizar la unidad, no
necesitará volver a realizar los mismos ajustes.
Atenuador electrónico de gran fiabilidad
El atenuador de nivel de entrada incorporado podrá ajustarse
dentro de un margen de 0 a 21 dB en pasos de 3 dB. Esto
reducirá la distorsión de la señal cuando se reciba una señal
de entrada de gran intensidad.
Portadora de RF con señal de tono
La unidad transmite la portadora de RF acompañada por una
señal de tono, lo que permitirá que el sintonizador, con su
circuito silenciador, elija solamente la señal de audio
pretendida.
Amplia gama dinámica y bajo ruido
El sistema compansor (compresor/expansor) permite la
transmisión en una amplia gama dinámica con el ruido
mínimo.
Conector de entrada de audio (3,5 mm de diámetro) con
mecanismo de bloqueo
El mecanismo de bloqueo de tipo tornillos asegura una
conexión fiable.
Antena helicoidal compacta
