Lectrosonics debuts new receivers

Lectrosonics, a manufacturer of wireless microphone systems and audio processing products, has introduced the SRB (pictured) and SRB5P (domestic) and SRB/E01, SRB5P/E01 (export) two-channel slot-mount Digital Hybrid Wireless diversity receivers. The new receivers offer two independent channels and fit into the standard video camera slots found on slot-equipped professional cameras such as those from Panasonic and Ikegami (SRB & SRB/E01) and Sony (SRB5P & SR5P/E01) by using the appropriate optional mounting kits. The two audio channels can feed separate inputs or can be mixed internally to feed a single input. The SRB family of receivers includes a newly designed receiver front end with a more robust RF amplifier stage and tighter IF (intermediate frequency) filtering. The results are significant performance enhancements over previous designs including better immunity to adjacent channel interference and increased sensitivity. Operating range is enhanced and greater multi-channel operation is now possible with fewer dropouts. A talkback feature is also included in the new receivers to work in conjunction with the HH handheld microphone transmitter. With the talkback feature engaged, one audio output is used for the standard signal feed. When the talkback button is pressed on the HH transmitter, the audio is routed to the second receiver output, which thus can be sent to an IFB (interruptible fold-back) system, a com desk, or anywhere else the user requires. Two diversity modes are offered in the SRB family. SmartDiversity reception is employed by combining antenna phase for each independent receiver channel. Alternately, the two channels can be used together as a single receiver in ‘True Diversity’ Ratio mode for enhanced performance in some environments. Graphic spectrum scanning provides quick and easy location of clear operating frequencies for interference-free operation. The two independent Digital Hybrid Wireless receivers inside the SRB Series units offer 256 frequencies each in a wide variety of available frequency blocks, and operate with any of the Lectrosonics’ 400 Series transmitters without a compandor in the audio path. In addition, compatibility modes also facilitate operation with Lectrosonics’ 100 Series, 200 Series, and IFB analogue systems, along with analogue transmitters from two other manufacturers.www.lectrosonics.com
