HT-S780 7.1-Channel Home Theater System
 

All too often, home theater packages disappoint - underpowered, poorly engineered, and over-rated. Onkyo has emphatically resolved these shortcomings with the HT-S780 7.1-channel receiver/speaker package. In terms of power, the HT-R530’s seven channels (a cumulative power of 1000 watts) deliver with power and authority. But sheer power means nothing without the audio circuitry design, technology and quality parts to back it up. Just like you’ll find in Onkyo separate components, core elements - WRAT (Wide Range Amplifier Technology), Optimum Gain Volume Circuitry, 192 kHz/24-bit digital-to-analog converters, a 32-bit DSP processing chip and an H.C.P.S.(High CurrentPower Supply) - provide the backbone for the home theater performance that is noticeably lacking in today’s market. Admirably supportedby the 7.1-channel speaker system (an impressive package in its own right), the HT-S780 distinguishes itself as a home theater system forthe mid-to large-sized family home.
