The WRR-850A is a high-performance tuner for the 800-MHz-band Sony
UHF wireless microphone system which uses the frequency bands
allocated for UHF TV broadcasting. This tuner enables application of
multiple channels over unused television channels through the use of the
built-in Sony original channel plan.
Phase Locked Loop (PLL) synthesized system
The unit has a refined phase locked loop (PLL) synthesizer circuit and
covers two UHF TV channels. It operates on 94 channels over a 12-MHz
frequency.
Built-in wireless channel plan for simultaneous
multichannel operation
The WRR-850A has many preprogrammed, easily settable channels in a
simultaneous multichannel operation. One group allows setting of 94
channels. The unit also has six preset groups of channels, each of which
permits simultaneous operation of 8, 11, 13, or 19 channels without the
effects of intermodulation. There is also a channel plan for 42 channel
simultaneous operation using the 6 TV bands on UHF TV channels 64 to
69.
Twin tuners
The WRR-850A has two tuner units. You can set the tuners to different
channels and still operate both at the same time.
Versatile display
A large liquid-crystal display provides a variety of information, including
the levels of the reception channels, RF information and transmitter battery
condition.
Space diversity reception system
The WRR-850A provides stable signal reception with minimum dropout.
Adjustable muting level
You can select the muting level (15 dBµ, 25 dBµ and 35 dBµ) to meet your
specific needs.
Tone squelch circuit for noise elimination
A built-in squelch circuit eliminates noise and signal interference when the
unit is in signal reception standby mode.
Compander system
A compander (compressor/expander) system enables stabilized wireless
transmission over a wide dynamic range.
Output monitoring
You can monitor the audio output using headphones. The level is
adjustable.
1U-size EIA rack mount
The unit can be mounted in an EIA-standard 19-inch rack (1U size).
