Main Features

Wide Dynamic Range
The MB-8N/WRU-8N provide a wide dynamic range,
thanks to advanced sound processing technology
developed by Sony. This wide dynamic range ensures that
the WRU-8N can provide optimum reception of signals
from current and future Sony wireless microphones and
transmitters.
Stable RF Reception
Three key technologies used in the WRU-8N UHF
Synthesized Tuner Unit result in extremely stable RF
reception, a vital factor for any wireless microphone system.
Firstly, the Phase Locked Loop (PLL) frequency
synthesized system employed in the WRU-8N provides
highly stable, selectable frequencies that permit reception
in increments of 125 kHz. Secondly, optimum combinations
of precisely calculated and practically tested frequencies
are stored in the tuner to help in choosing the correct
MB-8N/WRU-8N Front panel
frequencies for simultaneous multi-channel operation.
These frequencies are arranged in groups, with each
group pre-programmed to allow intermodulation-free
operation. Finally, a Space Diversity Reception System is
incorporated to effectively eliminate signal dropout and
provide stable reception. This is achieved by using dual
antenna input/reception circuits that receive signals over
two different paths and select the stronger RF signal as
the output.
Modular Design
The MB-8N Tuner Base Unit houses up to four WRU-8N
UHF synthesized tuner units in its 1U high, 19-inch rack
mountable design. This allows users to flexibly expand the
number of wireless channels in a system according to
their budgetary and operational needs. The compact
design of the base unit makes it easy to install in both
fixed and mobile applications.

Operational Convenience

The designs of the MB-8N and WRU-8N pay maximum
attention to operational convenience. Controlled items
can be adjusted from the main control area of the MB-8N
Tuner Base Unit, and the controls on individual WRU-8N
Tuner Unit.
Advanced control settings from the
MB-8N front panel
Using the controls and LCD panel built-in to the front of
the MB-8N Tuner Base Unit, users can quickly generate
and store channel names for each WRU-8N Tuner Unit
installed. Since the stored names can be recalled to the
base unit's LCD panel, operators can immediately verify
the sound source assigned to a given unit.
The output level (selectable to Mic or Line) and the
variable RF squelch level for each tuner unit are also
controlled from this main control area. Antenna
attenuator value and power supply ON/OFF to Sony AN-
820A UHF Antennas connected to the MB-8N Tuner
Base Unit are also selected here.
