Lectrosonics VRS VENUE Standard Receiver Module (Block 21)
Receiver module for the VENUE wireless system chassis.
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.
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.
The Venue Receiver is a modular solution that effectively deals with a congested RF spectrum with a variety of options that allows a system configuration to be idealized for a particular installation or application. The receiver is comprised of several components:
• The master rack mount host assembly
• Up to six receiver modules
• Built-in antenna multicoupler with loop-thru output
• LecNet2 software for setup and control
Flexibility is the core concept of the design. The receiver modules can be operated separately, each with switched diversity reception for a total of six audio channels, or operated in pairs for more robust diversity reception with one audio channel per module pair. Combinations can also be used for special applications where some modules operate independently and others are paired.
The receiver modules are easy to change with no tools required. The wideband multicoupler allows the use of any frequency module in any position, except when modules are paired, they must be in adjacent positions as marked on the panel.
A major benefit of the design is the inclusion of a high quality antenna multicoupler. The multicoupler is actually a 1 in, 7 out splitter with six outputs for the receiver modules and an additional output as a “loop thru” for another Venue receiver. This allows multiple Venue receivers to operate from a single pair of antennas. Phantom power for remote antenna amplifiers is available from the multicoupler antenna inputs using internal jumpers.
