Everything you need to add the Second Audio Program (SAP) channel to a TV station is contained in one complete package. TV Sidekick features a sync-lockable subcarrier generator, noise reduction encoding, audio processing and a peak deviation meter in one box.

It fully conforms to BTSC and FCC specifications for a SAP generator. It includes a subcarrier whose average frequency can be locked to five times horizontal sync and remain locked, regardless of the modulating signal. TV Sidekick also has an audio bandwidth of 50 Hz-10 kHz and an integrated audio processor that eliminates the need for an external processor, plus a tuning aid to minimize synchronous AM.

TV Sidekick allows easy integration with a station's stereo TV audio and is compatible with all aural exciters. It connects via a composite aural "loop through" method of feeding the composite baseband through and mixing it with the SAP subcarrier which then drives the wideband input of the aural exciter. Or, alternately, a separate high level SAP signal can feed the "SCA" or auxiliary input of many aural exciters as well as Modulation Sciences TSG Television Stereo Generator.

The audio processor portion of TV Sidekick is designed for subcarrier modulation and provides maximum intelligibility of dialog and music fidelity while delivering the greatest possible signal-to-noise ratio.
