Multi-channel Operation
The MB-8N and WRU-8N have been designed to
facilitate the setup of multi-channel wireless systems.
The MB-8N Tuner Base Unit is designed with a built-in
antenna divider, allowing four units to be daisy-chained
without the need of an external divider. Since each
tuner base unit accommodates up to four tuners, a 16-
channel system is easy to configure. With the use of an
optional Sony WD-880A Antenna Divider Unit,
simultaneous operation on up to 42 channels becomes
possible.
In combination with the pre-programmed channel
plans, building a high-quality, sophisticated, multi-
channel wireless system becomes a simple task.
For added operational convenience, the MB-8N/WRU-8N
system allows computer-based remote control. To provide
straightforward and intuitive operation, the MB-8N and installed
WRU-8N units can be set up, controlled and monitored from a
PC interfaced via a simple Ethernet connection and running
the supplied software.
Full monitoring of operating status in
one window
The GUI simultaneously displays the status of up to 16-
channels in one window, which can be switched to a 25-
channel or 49-channel display. Both a quick reference to
each tuner’s reception status and that of the entire
configuration are displayed on left side, while details of
the channel status are displayed on the right side.
Extensive range of operating controls
and information
Through a simple drag-and-drop operation, the operator
can designate the channels to appear on the right side for
access to an extensive range of operating controls and
information which includes the channel name, selected
channel group/frequency, tone squelch status, noise
squelch status, RF squelch level, AF/RF input levels and
transmitters battery alarm. The AF level is indicated in
steps of approximately 2.5 dB, while the RF level is
indicated in steps of approximately 5 dB.
The GUI also allows the control of all other settings
available on the MB-8N Base Unit.
Sophisticated jog dial control and
LCD/LED indicators
The controls on each WRU-8N UHF Synthesized Tuner
Unit specifically focus on channel/group number
selection, with a jog dial allowing operators to quickly
choose the desired setting. An LCD panel and LED
indicators provide extensive information on the tuner’s
operating conditions. The LCD indicates the operating
channel group and frequency, and has four-segment
displays of AF output level and RF input level, while the
LEDs indicate RF input status and AF output status and
the battery reserve of the transmitter. A red LED starts
flashing one hour before the transmitter’s battery will
become exhausted, helping to avoid the chance of a
battery failure at a critical moment.
Selectable monitor output modes with
level control
The headphone monitor jack and level control are located
on the front panel of the MB-8N Tuner Base Unit. This output
can be selected to monitor the sound from individual
WRU-8N tuner units or the mixed sound from all installed
units.
