Overview

Lectrosonics Venue 2, 6-Channel Modular Receiver - Chassis Only, Requires VRT2 Receiver Modules

The Lectrosonics 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 multicoupler 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 wideband multicoupler 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 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 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 via menu selection.

  • iQ dynamic tracking filters for enhanced RF performance
  • Wireless Designer setup and control software included
  • Talkback function with select transmitters
  • Ethernet, USB and RS-232 computer interface ports
