Features - Sony WRT-822A Mode D'emploi

Features

Phase Locked Loop (PLL) synthesized system
The WRT-822A has a refined phase locked loop (PLL)
synthesizer circuit.
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 Sony tuners which support the battery
status indication on both transmitter and tuner.
The information is sent to the tuners in approx. one hour
advance to battery exhaust so that they can safely replace
batteries of the transmitter.
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.
Compatibility with Sony lavalier microphone
The transmitter is compatible with Sony lavalier
microphones, including the ECM-77BC.
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
