Overview
The WRT-822A is a transmitter for an 800 MHz band UHF
synthesized wireless microphone system to be used for
general purpose.
The other system components include the WRT-800A/
810A/830A/867A UHF Synthesized Wireless Microphone,
the WRT-822A/860A UHF Synthesized Transmitter, the
AN-820A UHF Antenna, the WD-820A UHF Antenna
Divider, the WRR-805A/ 810A UHF Synthesized Tuner, the
WRR-800A/ 801A/ 820A/840A/850A/855A/860A UHF
Synthesized Diversity Tuner.
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-822A/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-822A/
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.
For the selectable channels, see the following pages:
“Sony Original Channel Groups” (62ch Model) on page L-3.
“German User Group-3” (62ch Model) on page L-6.
“German User Group-4” (62ch Model) on page L-7.
“German User Groups” on page L-8.
CE69 model
An 8-MHz frequency band is assigned to the WRT-822A/
CE69 model, permitting it to operate on any of 64 carrier
frequencies in 125-kHz steps of Sony original channel plan
or 14 carrier frequencies in 25-kHz steps of UK General
Use.
For the selectable channels, see the following pages:
“Sony Original Channel Groups” (69ch Model) on page
L-13.

Features
Phase Locked Loop (PLL) synthesized system
The WRT-822A has a refined phase locked loop (PLL)
synthesizer circuit.
Preprogrammed wireless channel plans for simultaneous
multi channel operation
The WRT-822A 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
Innovative high-density mounting technology and
magnesium case have enabled the creation of this compact
and lightweight transmitter, which lets you move anywhere
for Electronic News Gathering (ENG) and Electronic Field
Production (EFP).
Remote battery alarm on tuner
This transmitter has capability of transmitting “Battery
status information” to the WRR-800A/801A/805A/850A to
give advance warning of battery depletion.
The information is sent to the WRR-800A/801A/805A/
850A in approx. one hour advance to battery exhaust so that
they can safely replace batteries of the transmitter.
When the WRR-800A/801A/805A/850A receives the
information, the LED and the LCD on the panel start
flashing.
Operation powered by easily available batteries
The built-in high efficiency DC-DC converter allows stable
operation, for about 8 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, 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 one-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 batteries are 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.

Merkmale
PLL-Synthesizer-System (PLL = Phase Locked Loop)
Der WRT-822A verfügt über einen verfeinerten PLL-
Synthesizer (PLL = Phase Locked Loop - Phasenregelkreis).
Vorprogrammierte Kanalpläne für gleichzeitigen,
schnurlosen Mehrkanalbetrieb
Im WRT-822A sind viele Kanalgruppen vorprogrammiert,
die bei einer Kombination von schnurlosen Kanälen den
gleichzeitigen Mehrkanalbetrieb ohne Intermodulation
ermöglichen.
Die verfügbaren Gruppen und Kanäle können einfach per
Tastendruck ausgewählt werden.
Kompakt und leicht
Dank modernster Montagetechnologie auf kleinstem Raum
und dank des Magnesiumgehäuses ist dieser Sender äußerst
kompakt und leicht. Damit eignet er sich ideal für ENG
(Electronic News Gathering) und EFP (Electronic Field
Production).
Übertragung eines Batteriealarmsignals an Tuner
Dieser Sender kann Batterieladeinformationen an den WRR-
800A/801A/805A/850A übertragen und somit rechtzeitig
vor verbrauchten Batterien warnen.
Diese Informationen werden etwa eine Stunde, bevor die
Batterien erschöpft sind, an den WRR-800A/801A/805A/
850A gesendet, so daß ausreichend Zeit bleibt, die Batterien
des Senders auszutauschen.
Wenn die Informationen am WRR-800A/801A/805A/850A
eingehen, beginnen die LED- und die LCD-Anzeige am
Bedienfeld zu blinken.

Der Sender ist kompatibel mit Ansteckmikrofonen von
Sony, z. B. dem ECM-77BC.
HF-Träger mit Pilottonsignal
Das Gerät überträgt das HF-Trägersignal zusammen mit
einem Pilotton, der es dem Tuner mit
Rauschunterdrückungsschaltkreis ermöglicht, nur das
gewünschte Audiosignal zu empfangen.
Großer Dynamikbereich und geringes Rauschen
Dank des Kompander-Systems (Kompressor/Expander) ist
eine Übertragung über einen großen Dynamikbereich mit
geringem Rauschen möglich.
