The New Lectrosonics VRM 2-941
Block 941 (941.525 - 959.825 MHz)
The Venue 2 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 multi-coupler with loop-thru output
• 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 wide-band multi-coupler allows the use of any frequency module in any position, except when modules are paired for ratio diversity reception.
A major benefit of the design is the inclusion of a high quality antenna multi-coupler. The multi-coupler 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 receivers to operate from a single pair of antennas. Phantom power for remote antenna amplifiers is available from the multi-coupler antenna inputs via menu selection.
