Overview
Up to six Lectrosonics VRT2 modules may be installed per each 1RU Venue 2 receiver frame. Each module supports up to 3072 tunable frequencies across a 75 MHz range (three standard Lectrosonics blocks), matching the tuning ranges of SSM, LT and LMb "large bandwidth" transmitters. VRT2 modules incorporate Lectrosonics' new iQ dynamic tracking filters, which accommodate a wide range of transmitter RF power levels while also enabling extremely tight channel spacing—critical features as the available RF spectrum continues to shrink.
The receiver modules can be operated independently, 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 be mixed and matched within one frame. Receiver modules are easy to change, with no tools required, and may be installed in any position, except when paired for ratio diversity reception. The VRT2 modules are offered in different frequency ranges:
