Overview

The WD-850 is a UHF antenna divider for use with a Sony
UHF wireless microphone system.
Antenna signal output to up to four
receivers
This unit is equipped with a 2-channel divider circuit that
allows it to send the antenna signals received by two AN-
820A UHF antennas to up to four receivers. This makes it
possible to easily configure a multi-channel diversity
receiving system by connecting Sony MB-X6/8N tuner
base units or similar equipment.
Cascade output connectors allowing
simultaneous use of up to two WD-850
channel dividers
Connection of the unit's cascade connectors to two WD-
850 channel dividers enables signal output to a maximum
of eight tuner base units.
2-channel antenna input connectors
This unit provides two connectors for each channel.
Increasing the number of antennas to four makes it
possible to extend the range of wireless microphone use.
Power supplied to the AN-820A UHF
antenna
Power is supplied to the AN-820A UHF antenna's booster
amplifier. Interference or distortion can be easily
eliminated by turning off the power to the booster
amplifier.
1U-size EIA rack mount
The unit can be mounted in an EIA standard 19-inch rack
(1U size).

About the use of coaxial cable

5D-2V or a higher grade coaxial cable (50 ohms) is
recommended for connecting the antennas to the tuner or
antenna divider. Use of 5C-2V or higher grade (75 ohms)
is also possible.
Signal loss: 5D-2V 50 m (164 ft.): 12.5 dB
100 m (328 ft.): 25 dB
5C-2V 50 m (164 ft.): 13.5 dB
100 m (328 ft.): 27 dB
Since signal loss in coaxial cable is affected more by the
length of the cable than the difference between 50 ohms
and 75 ohms, the cable should be as short as possible.

Operating conditions

Operate within a temperature range of 0C° to +50C°
(+32F° to +122F°).
