A built-in squelch circuit eliminates noise and signal
interference when the tuner is in signal reception
standby mode.
Compander system
A compander (compressor/expander) system enables
stabilized wireless transmission over a wide dynamic
range.

Overview
These operating instructions describe the MB-806A
Tuner Base Unit in which the optional WRU-806A/
WRU-806B UHF Synthesized Tuner Unit is installed.
The unit is a reliable UHF synthesized diversity tuner
for the Sony UHF wireless microphone system which
uses the frequency bands allocated for UHF TV
broadcasting.
This tuner is designed to enable simultaneous use of
multiple channels when channels are selected
according to the Sony channel plan.
Installing six WRU-806A/WRU-806B UHF
Synthesized Tuner Units will enable six-channel
operation on the tuner.
For the selectable wireless channels and frequencies, see
“Wireless Channel Lists” on page L-1 (for WRU-806A
users) or refer to “Wireless Microphone System Frequency
List” supplied with the WRU-806B (for WRU-806B users).
Features
Phase Locked Loop (PLL) synthesized
system
The tuner 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
(WRU-806A) or 188 channels over a 24-MHz
frequency (WRU-806B).
Preprogrammed wireless channel plan for
simultaneous multichannel operation
The tuner has many preprogrammed, easily settable
channels for simultaneous multichannel operation. One
group allows setting of 188 channels. The tuner also
has 9 preset groups of channels, each of which permits
simultaneous operation without the effects of
intermodulation.
Modular multichannel reception
By installing optional WRU-806A/WRU-806B UHF
Synthesized Tuner Units, you can receive up to six
channels on one MB-806A unit.
