Lectrosonics VRM2WBL
MPN #VRM2WBL
The Venue 2 Receiver is a modular solution that effectively deals with a congested RF spectrum with a variety of options.
The receiver is comprised of several components:
The master rack mount host assemblyUp to six receiver modulesBuilt-in antenna multicoupler with loop-thru outputSoftware 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 mod- ules 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 mod- ules are paired for ratio diversity reception.
A major benefit of the design is the inclusion of a high quality antenna multicoupler. The multicoupler is actually a dual 1 in, 7 out splitter with six outputs for the receiver modules and an additional output as a "loop thru" for an- other Venue receiver. This allows multiple Venue receiv- ers to operate from a single pair of antennas. Phantom power for remote antenna amplifiers is available from the multicoupler antenna inputs via menu selection.
Digital Hybrid Wireless
is a revolutionary design that combines digital audio with an analog FM radio link to provide both out- standing audio quality and exemplary, noise-free RF performance.
Using a patented algorithm to encode 24-bit digital audio information in the transmitter into an analog format, the encoded signal is then transmitted over an analog FM wireless link.
At the receiver, the signal is then decoded to restore the original digital audio. This process eliminates compandor artifacts and produces an audio frequency response flat to 20 kHz.
