Wheatstone SG-192 FM Stereo GeneratorModel Number: SG-192
The SG-192 is the first standalone FM stereo generator capable of passing full AES MPX composite baseband to the exciter, including RDS and SCA up to 67kHz, and is equipped with an intelligent stereo multipath controller which helps mitigate the effects of multipath-induced receiver blending.
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.
The SG-192 can be added at the studio or the transmitter site, depending on the STL in use, and comes with highly oversampled, low distortion composite clipping. A crisp front panel OLED display makes adjustments easy and the front panel headphone output allows confidence monitoring of the stereo generator’s input signals.
The SG-192 can be used with any audio processor and for translator or repeater applications.
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.
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.
Exclusive Multipath Control
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!
