Features
Easy selection of 94 channels
The PLL synthesized system assures easy selection of 94
channels and full compatibility with Sony 800 MHz series
wireless microphone system.
Easy and reliable connection
The WRT-808A can be adapted to a wide variety of wired
microphone which has a XLR audio connector. The reliable
connection assures the noise-free operation.
Compact and lightweight
High density mounting technology enables this compact and
light weight transmitter, to allow you to move anywhere for
Electronic News Gathering (ENG) and Electronic Field
Production (EFP).
Operation powered by easily available batteries
Approximately four hours of continuous operation is
ensured with two AA-size (LR6) alkaline batteries. By
virtue of DC-DC converter, consistent output power is
assured over the life of the batteries.
Battery status information on both transmitter and
tuner
To avoid the battery failure, the WRT-808A shows the
battery status with the LED indication in green, red and
flashing. About one hour before the battery exhausted, the
WRT-808A gives the battery information to make the alarm
on the tuner WRR-800A/801A/805A/850A.
LED indication of audio input
The AF/PEAK indicator allows you to comprehend the
condition of audio input level at a glance.
Continuous control of input attenuation
When an excessively strong audio signal is inputted, the
input level can be adjusted in the range of 0 to 50 dB
continuously.
When setting the 50 dB attenuation, the WRT-808A can
4 dB (maximum 20 dB) line level input.
Selectable RF power output
You can select the RF output level either 50 mW or 10 mW
to suit the operating condition.

The transmitter can operate on two LR6 (size AA) alkaline
batteries continuously for about 4 hours at 25°C (77°F).
Installing the batteries
Power Supply
1
Turn the battery-compartment screw counterclockwise.
2
Match the polarities and insert the batteries.
3
Close the lid.
Battery indication
When you turn the power on, the POWER/BATT indicator
lights in green.
While in operation, the POWER/BATT indicator shows the
battery condition as shown below.
Lights in green: Good
Lights in red: The battery level is low. About one hour
is left for continuous operation.
Flashing in red: The batteries are almost exhausted.
The unit does not work.
Promptly replace the batteries when the POWER/BATT
indicator lights in red or flashes.
When the POWER/BATT indicator lights in red on this unit,
the BATT indication on the tuner (WRR-800A/801A/805A/
850A) starts flashing as a warning.
Note
The indication may be incorrect if the batteries are not new
when installed. If you plan to use the transmitter for a long
period, it is best to replace the batteries with new ones.
