Our high-current WRAT system uses a customized massive transformer and extra-large capacitors to drive discrete Three-Stage Inverted Darlington Circuitry on the L/R/C channels. Powerful and controlled amplification serves as a bed for Dolby Atmos, a new audio format that uses object-oriented mixing to unleash overhead sound effects through height channels. Or sit back and let the premium 7.1-channel THX speaker package bring Dolby® TrueHD and DTS-HD Master Audio™ movie soundtracks to life. These quality A-OMF two-way speakers fill rooms with clear, dynamic, and detailed sound, with a huge sealed subwoofer shaking the walls with high-impact bass. Marrying the latest A/V processing and upscaling technology to high-current analog power, the HT-S9700THX lets you escape into your choice of entertainment with a few taps on your smartphone.
