The Lectrosonics SRc Dual-Channel Slot-Mount ENG Receiver (A1: 470.100 to 537.575 MHz) design includes two separate receivers built into a single, ultra compact housing with adapters for video camera receiver slots and for standalone use. Digital Hybrid Wireless technology provides superb, compandor-free audio quality and compatibility with other wireless systems. The Lectrosonics SRc Dual-Channel Receiver performance is extremely stable over a very wide temperature range, making the receiver perfectly suited to the rough environmental conditions found in field production.

DSP compatibility modes allow the receiver to be used with a variety of Lectrosonics systems, other brands of wireless systems and with Lectrosonics IFB transmitters. The front panel features a menu-driven LCD interface and four membrane switches which are used to view and alter settings. The main LCD window displays the pilot tone indicator, diversity activity, RF level, audio level and transmitter battery status for both receivers. To find clear operating frequencies, a built-in spectrum analyzer scans across the tuning range of the receiver and displays a histogram of RF activity across the band.

Areas with little or no RF activity are easily recognizable. The two internal receivers can be operated separately, each using switching, antenna combining diversity or in tandem with ratio diversity reception. The audio outputs of the receivers can be mixed internally or left separated for discrete recording tracks or external mixing. A variety of output adapters and mounting options are available for camera slot operation. The receivers are powered from an external 7 to 18 volt DC source.

  • Fits camera "slots," Lectrosonics Duopack adapter and Octopack multicoupler, and operates stand-alone with various adapters
  • Dual-receiver design for two channels with phase switched diversity or single channel with ratio diversity operation
  • Digital Hybrid Wireless with compatibility modes for use with other transmitters
  • Tracking front-end filters for high performance in tough RF environments
