UHF Wireless Microphone Systems
Despite its compact design, the WRR-862 simultaneously
receives two independent RF signals on two separate
channels. A space diversity system is employed on both
channels to eliminate signal dropout and provide stable
reception. Two SMC9-4S (Sony 4-pin) audio output
connectors are provided on the top panel.
The WRR-862 is available in two versions. The WRR-862A
operates over a 14 MHz frequency band within the range
792 MHz to 806 MHz (AU), while the WRR-862B model
operates over a 24 MHz frequency band between 470 MHz
and 806 MHz (UC), or 470 MHz to 862 MHz (CE).
The operating frequency of the WRR-862B specifically
accommodates the re-allocation of wireless operation
frequency band due to the advent of Digital TV broadcasting.
The WRR-862 dual diversity tuner has LED and LCD displays
to provide extensive range of information.
●
LED for each channel to indicate RF input level (green/
red indication), diversity reception status and transmitter
battery alarm.
●
LCD for each channel to indicate operating channel/
frequency, AF output level, RF input level, receiver battery
status and accumulated battery operating time.
Dual Diversity Tuner
Operating
frequency ranges

This dual diversity tuner is extremely compact and light-
weight. At only 400 g (14.1 oz) including batteries, it is easily
mounted on Sony professional camcorders with the supplied
attachment kit and case.
Approximate five
*2
hours of continuous operation is provided
by four AA-size alkaline batteries. The WRR-862 is also capable
of operating on external power from Sony camcorders via
the supplied DC cable.
The WRR-862 incorporates RF squelch that is easily turned
ON or OFF. When turned ON, the RF level is selectable from
5 dBµ, 10 dBµ and 15 dBµ.
The WRR-862 includes a stereo mini jack for monitoring
the output sound (switchable: Tuner 1/2/mixed) with head-
phones. A monitor volume control is also included.
