Dynamic Audio Amplification
Backed by 70 years of experience building high-grade audio components, the HT-S7800 amplifies accurate, noise-free signal processing with high-current power for dynamic speaker control. The result is pure, rich and authentic sound.
Onkyo's dynamic audio amplification delivers massive power at 170 W/Ch (6 Ohms, 1 kHz, 0.9% THD, 1 Channel Driven)/ 100 W/Ch (8 Ohms, 20 Hz–20 kHz, 0.08% THD, 2 Channels Driven).
Powerful Speaker Set
The 2-Way bass reflex front left and right speaker cabinets also house the full-range acoustic-suspension Dolby Atmos-enabled height speakers. These special drivers bounce discrete sound effects off the ceiling into your listening space. Besides producing amazing traditional surround sound, each solidly crafted speaker in this 5.1.2 package reproduces the latest object-based surround sound as its creators intended.
The HT-S7800 Powered Zone 2 brings audio to speakers connected to the receiver into a second room. With the dedicated Zone 2 DAC for Net & SPDIF, you can send internet audio and digital audio sources connected via coax or optical (such as Apple TV) to your second listening zone.
Supports Dolby Atmos Up to 5.1.2 Channels
Dolby Atmos moves sound around you in three-dimensional space, so you feel like you're inside the action. The HT-S7800's Dolby Atmos decoding transports you from the ordinary into the extraordinary.
Sound designers and artists mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels.
Additionally, the Dolby surround up-mixer processes content not mixed for Dolby Atmos to fill the flexible speaker layouts of a Dolby Atmos system.
