VRT Modular Receiver System
Receiver Modules
(The
VRS standard module has fixed front-end filters that cover its 25.5 MHz
tuning range)
The higher selectivity VRT module has a much narrower
tracking front-end filters that retune as the frequency is changed to
stay centered over the selected frequency.
The
modules are a triple conversion, frequency synthesized design,
controlled by the microprocessor in the host assembly. A common DSP in
the host assembly is used for all six receiver modules to decode the
received signals and restore the digital audio. Using a single DSP
results in a significant reduction in cost per channel.
The
host assembly will handle up to six receiver modules via multi-pin
connectors on the side of the main housing. The modules are held in
place with snap-in retaining clips. The clips hold the modules firmly
but are easy to remove without tools to make needed changes.
Hardware Installation
VRS
and VRT receiver modules can be mixed in the same chassis. For ratio
diversity operation, both modules in the pair must be on the same
frequency block and positioned in the assembly in keeping with
the OPTI-BLEND labeling on top of the chassis housing.
All
modules must be within the frequency passband of the host assembly.
Frequency blocks are marked on the receiver module and chassis housings.
VRT & VRS modules are not compatible with newer Venue2 frames.
