Precautions
On operation
• The tuner must be used within a temperature range of
0°C to 40°C (32°F to 104°F). Avoid using the tuner
for extended periods at extremely high temperatures
or placing it in direct sunlight, especially outdoors,
because this may damage the finish of the case.
Never install the tuner on or near a heat source, such
as lighting equipment or power amplifiers.
•Avoid using in very humid or dusty places, because
such use may shorten the life of the tuner.
•To avoid degradation of the signal-to-noise ratio, do
not use the tuner in noisy places or in locations
subject to vibration, such as the following:
–near electrical equipment, such as motors,
transformers or dimmers
–near air conditioning equipment or places subject
to direct air flow from an air conditioner
–near public address loudspeakers
–where adjacent equipment might knock against the
tuner
•Switching lights on or off may produce electrical
interference over the entire frequency range. Position
the tuner and the wireless microphones so that
interference is minimized.
•The tuner is precisely adjusted at the factory and no
adjustment before use is necessary. Do not touch the
inside of the tuner or try to repair it by yourself.
•Do not use the unit when its fan is not working.
Using the unit with the fan being in fault may cause a
fire.
About fan replacement, contact your Sony dealer.
On cleaning
Clean the tuner with a dry, soft cloth. Never use
thinner, benzene, alcohol or any other chemicals, since
these may damage the finish.

Features
LAN function
The built-in network adapter and provided 10BASE-T
connector enables a LAN connection to a computer
running the Windows operating system. Using the
supplied MB-8N Network Controller software, it is
possible to operate an efficient system for central
control of MB-8N Tuner Base Units and WRU-8N
UHF Synthesizer Tuner Units from a computer.
Modular multichannel reception
By installing optional WRU-8N UHF Synthesized
Tuner Units, you can receive up to four channels on
one MB-8N unit.
Built-in antenna divider
With a built-in antenna divider and provided with a
cascade output connector, without requiring the
connection of an antenna divider unit, the MB-8N
Tuner Base Unit can be connected in cascade. For a
maximum of four MB-8N Tuner Base Units (16
channels1)), you can build a diversity receiving system
with two antennas.
Phase Locked Loop (PLL) synthesized
system
The tuner has a refined phase locked loop (PLL)
synthesizer circuit and covers two UHF TV channels.
Preprogrammed wireless channel plan for
simultaneous multichannel operation
The tuner has many preprogrammed, easily settable
channels for simultaneous multichannel operation.
Overview
These operating instructions describe the MB-8N
Tuner Base Unit in which the WRU-8N UHF
Synthesized Tuner Unit (option) is installed.
Note
For the selectable wireless channels and frequencies,
refer to the Frequency Lists on the supplied CD-ROM.
Combining the MB-8N Tuner Base Unit and the
WRU-8N UHF Synthesized Tuner Unit (option)
provides a reliable UHF synthesized diversity tuner for
the Sony UHF wireless microphone system which uses
the frequency bands allocated for UHF TV
broadcasting.
The combination of the MB-8N and the WRU-8N
enables simultaneous use of multiple channels when
channels are selected according to the Sony channel
plan.
Installing four WRU-8N UHF Synthesized Tuner
Units will enable four-channel operation on the tuner.
In building up a UHF wireless microphone system, be
sure to combine a microphone/transmitter and a tuner
having the same TV channel number.
When using CE models of WRU-8N
A 24-MHz frequency band is assigned to the WRU-
8N, permitting it to operate on any of 189 (190 with
the CE67 model) receiving frequencies in 125-kHz
steps of Sony original channel plan or 960 receiving
frequencies in 25-kHz steps in the range of three TV
channels.
When using U models of WRU-8N
A 24-MHz frequency band is assigned to the WRU-
8N, permitting it to operate on any of 188 receiving
frequencies in 125-kHz steps of Sony original channel
plan in the range of four TV channels.
When using the AU model of WRU-8N
A 14-MHz frequency band is assigned to the WRU-
8N, permitting it to operate on any of 102 receiving
frequencies in 125-kHz steps of Sony original channel
plan in the range of TV channels 66 and 67.
........................................................................................................................................................................................................
1) When each MB-8N Tuner Base Unit has four WRU-8N
UHF Synthesizer Tuner Units installed. Note that the
receiving system consisting of the MB-8N and the AU
model ot WRU-8N allows you to simultaneously use a
maximum of 12 channels in one area.

Overview
Versatile display
A liquid-crystal display and LEDs provide a variety of
information, including the levels of the reception
channels, RF information and transmitter battery
condition.
Space diversity reception system
The tuner provides stable signal reception with
minimum dropout.
Tone squelch circuit for noise elimination
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.
Rack mounting
The MB-8N can be mounted in an EIA standard 19-
inch rack (1U size).
Channel Plan
The tuner stores several groups of channels. (Refer to
“Overview of Channel Plan” in the Frequency Lists on
the supplied CD-ROM.)
Channel groups other than group 00 (and groups of 25-
kHz steps with CE models) are designed so that all
channels of one group can be used simultaneously
within the same UHF wireless microphone system
without causing intermodulation. It is therefore
recommended that you usually use a channel group
other than group 00 (and groups of 25-kHz steps with
CE models) unless the use of group 00 (or any group
of 25-kHz steps with CE models) is specifically
necessary.
Using the CD-ROM
The supplied CD-ROM contains the following files.
Note
To use the MB-8N Network Controller, it is necessary
to install it in your computer.
For the installation procedure, see “Installation” on the
next page.

Connect to a Windows computer, in order to use the
supplied MB-8N Network Controller software for
communications with the computer.
For connection to a computer, use a category 5 LAN
cable with a maximum length of 100 m (330 ft). If the
connection requires a total cable length exceeding
100 m (330 ft), use a hub between the computer and
this unit.
Use the following type of cable when:
Directly connecting the computer and this unit:
cross cable
Using a hub between the computer and this unit:
straight cable
Caution
Only connect 10BASE-T cables to the (Ethernet
network) port. Do not connect any other type of
network cable or any telephone line. Connecting
cables other than those listed above may result in an
electric current overload and could cause a
malfunction, excessive heat, or fire in the connector.
To connect the unit to the network, contact your
network manager.

Organization of Setting Menus
Local menu
When this unit is in local mode, the MB-8N display
shows “***Local Menu***,” and the setting menus

You make the settings from submenus.
