September 29, 2000Building on the success of the 800 Series
UHF Wireless Microphone System, Sony Electronics is introducing the latest additions to the
wireless microphone family: the newly developed WRT-847B UHF Synthesized transmitter unit
with interchangeable microphone heads and the WRR-862B UHF synthesized Dual Diversity
Tuner.
"Compatible with our existing receiving systems, the WRT-847B allows flexible,
simultaneous, multi-channel operation and operates over a 24 MHz frequency band," said Paul
Foschino, marketing manager for professional audio products of Sony Electronics' Broadcast
and Professional Company. "Suitable for a wide range of broadcast, concert sound and other
applications, the WRT-847B is a really versatile product."
Five types of microphone heads are available for use with the WRT-847B. The CU-F780,
CU-G780 and CU-E700 optional microphone capsules are designed for such vocal applications
as broadcasting and live concerts. The CU-E672 and CU-F117 microphone capsules are intended
for interviews in news gathering and field productions.
The WRT-847B transmitter unit offers several key features including: selectable RF
output level (10 mW for multi-channel operation and 50 mW for long working distance); audio
gain and attenuation setting from +9 dB to –12 dB in 3 dB steps; and-easy-to-read LCD with
back light that indicates extensive information on operating conditions, such as channel number,
wireless channel frequency in MHz, audio input level, compander time constant, battery status
and accumulated operating time.
The compact WRR-862B unit also operates over a 24 MHz frequency band and has two
built-in tuner modules to meet the demand for two-channel reception in ENG and EFP
applications. Designed so that it can be easily mounted on Sony cameras, the tuner's magnesium
diecast body is extremely lightweight and rugged.
"The WRR-862B can simultaneously receive two independent signals on two separate
channels," Foschino reported. "The space diversity system is employed to eliminate signal
dropout and provide stable reception."
Two SMC9-4S (Sony 4pin) audio output connectors are provided on the top panel.
Additional features include:
- LED and LCD indication to provide extensive information;
-
Long operating time - approximately five hours of continuous operation provided by four
AA-size alkaline batteries; or DC power connection for deriving power from the camera.
-
Switchable RF squelch which can be easily turned ON and OFF;
- Monitor jack for monitoring the output sound.
"Since its introduction, Sony's 800 Series system has been well accepted in the market
for its wide dynamic range, low noise characteristics, stable signal transmission and reception,"
said Foschino. "We are pleased to build upon and strengthen the wireless series."
The date of availability and pricing for these wireless microphones and components is still to
be determined.
