The SG-192 FM stereo generator complements Wheatstone’s audio processing line and can provide stereo generation for third-party audio compressors and limiters that lack a stereo generator or are installed in a location where the stereo generator cannot be used. It offers an exclusive stereo multipath controller, which helps mitigate the effects of multipath-induced stereo receiver blending in the absence of clean reception. Audio interfaces for the exciter include the legacy composite analog signal (2 separate outputs are available) or Wheatstone’s baseband192 AES digital composite baseband option for compatible exciters. A dedicated 10MHz synchronizing input is useful for single frequency networks, translators, and repeater applications.
The SG-192 is equipped with Wheatstone’s baseband192 technology, the only digital MPX technology that digitally samples the composite baseband at 192kHz in order to include the FM composite signal as well as RDS and SCA subcarriers up to 67kHz. Digitally adding RDS and SCA signals to the digital composite baseband eliminates the noise problems created by analog technology, which translates to a lower noise floor and less crosstalk between subcarriers.
Wheatstone® baseband192 digitizes the entire multiplex spectrum including RDS and SCAs up to 67kHz, doing away with the conventional and noise-prone analog composite interface between processing and transmission. A single AES/EBU cable between the SG-192 and a current solid-state FM transmitter carries the entire digital baseband signal, eliminating the need for stereo multiplexing in the exciter and also eliminating the resulting signal overshoot and loudness tradeoffs associated with it. Wheatstone’s baseband192 is the only digital MPX technology that samples the baseband at 192kHz to include the FM composite as well as RDS and SCAs up to 67kHz.

Exclusive to the Wheatstone line of audio processors and now the SG-192 stereo generator is our Stereo Multipath Controller. A single user control sets the algorithm for market and terrain-specific multipath environments and helps to mitigate the audible effects of receiver-induced stereo blending due to multipath conditions. The result is a clearer stereo experience for listeners often accompanied by the perception of increased coverage area.
The WheatNet-IP interface makes it possible to control the SG-192 from anywhere in the IP audio network, making it just as flexible as WheatNet-IP surfaces and controllers!

How can radio stations enhance their relationships with listeners? One way is through better use of audio processing technology. Because audio processing is such a subjective topic, we asked a wide variety of individuals to contribute their views. You'll hear from 26 processing experts in this new white paper.

IP Audio Networks: Planning for Reliability A white paper by Andrew Calvanese, VP Engineering, Wheatstone Corporation
WheatNet-IP brings added convenience and simplicity to the configuration of a PC- based automation system such as RCS Zetta. Where once it was necessary to employ a specialized sound card, discrete analog or digital audio wiring, a logic interface, and control cabling, with WheatNet-IP’s PC Driver, we can accomplish all of this over a single Ethernet cable. The driver effectively acts as a WheatNet-IP BLADE, and lets the PC enjoy full access to all aspects of the WheatNet-IP intelligent network. The driver is available in versions that offer one, four, eight, twelve, and twenty-four stereo input and output channels. For situations where discrete outputs from Zetta players are desired, we recommend at least the four-channel version of the driver.
