Product Overview
The Lectrosonics SRC consists of two separate receivers built into a single, ultra compact housing with adapters for video camera receiver slots and for stand-alone use. Digital Hybrid Wireless® technology provides superb, compandor-free audio quality and compatibility with other wireless systems. The RF 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.
