The SRB receiver offers two independent channels and fits into the standard video camera slots found on professional cameras. The two audio channels can be fed separate inputs or can be mixed internally to feed a single input.
The two Digital Hybrid Wireless receivers inside the SRB offer 256 frequencies each in one of nine available 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 analog systems, along with analog transmitters from two other manufacturers. Transmitter battery strength is monitored in the SRB when using compatibility modes for 200 and 400 Series transmitters.
While mounted on a camera, the SRB is splash resistant—thanks to sealed membrane switches and LCD, along with a special gasket covering the slot opening.
NOTE: Not all cameras have two audio channels enabled in the slot.
The LMa Beltpack Transmitter incorporates their patented Digital Hybrid Technology and an improved audio input signal path. The wireless beltpack transmitter is completely compatible with any of the Lectrosonics Digital Hybrid receivers and features a TA5-male input connection for lavaliers, instrument pickup cables and line level signal.
Digital Hybrid Technology combines a 24-bit digital audio chain with an analog FM radio link that eliminates compandor circuits and any associated noise. In addition, analog compandor emulation allows the transmitter to work with third-party and Lectrosonics 100, 200 and IFB series wireless systems.
An improved audio input features Servo Bias Wiring, which reduces overload and eliminates the need to introduce pads on certain microphones. Standard in most Lectrosonics wireless beltpacks are 256 selectable frequencies, a versatile battery compartment that accepts any 9V battery and a rugged die-cast metal enclosure.
