New Bern, NC - Jul 1, 2013 - Wheatstone is now shipping its FM audio processors with new Wheatstone Baseband192 technology for direct AES3 output into any FM transmitter equipped with a digital baseband input.
Wheatstone Baseband192 uses open standard technology that eliminates the need for an analog composite interface between processing and transmission, clearing the last obstacle to a 100 percent digital air chain.
A single AES/EBU cable between a Wheatstone processor and the transmitter carries the baseband signal, bypassing the need for multiplexing in the exciter and eliminating the resulting signal overshoot with associated loudness tradeoff.
"We simply digitize the entire multiplex spectrum up to and including the RDS, then send that digitized signal directly to the modulator of the exciter," explained Jeff Keith, senior Wheatstone product design engineer.
The Baseband192 interface is now available as a standard feature in Wheatstone AirAura X3, FM-531HD and VP-8IP audio processors.
