Audio / Video Multi-Channel Receiver VSX-D811SGet totally surrounded with the VSX-D811S! Pioneer designed this home theater powerhouse with 100 watts x 6 channels of power, plus built-in decoding for Dolby® Digital EX and DTS-ES® sources. That means the only thing you'll need to achieve stunning, 360º 6.1-channel sound is a standard 5.1 home theater speaker system plus a sixth "back surround" speaker. This receiver even has two back surround speaker terminals, so if you want to add a pair of speakers, you can share the sixth-channel power between the pair.Making multichannel matters even more exciting, Pioneer's 6.1 Expanded Theater processing creates 6.1-channel sound from Dolby Digital, DTS, and Dolby Surround sources. You can even use all your speakers when listening to stereo music, thanks to 6-channel stereo mode.The VSX-D811S offers plenty of connectivity, including component video switching, plus front-panel S-video and optical digital inputs for easy hookup of portable A/V gear. You also get multichannel preamp ins and outs (7.1-channel in, 6.1-channel out) that not only accommodate high-resolution audio formats like DVD-Audio and SACD, but also keep you poised and ready for new formats and system expandability down the road. And Pioneer's learning/multibrand remote gives you easy system control.Details:Dolby Digital EX, DTS-ES, and Dolby Pro Logic™ IIDTS Neo:6 modes100 watts x 2 (stereo) into 8 ohms (20-20,000 Hz) at 0.2% THD — or 100 x 6 in surround modelearning/multibrand remotePioneer 6.1 Expanded Theater6-channel stereo7.1-channel preamp input6.1-channel preamp outdigital inputs: 3 optical (1 front-panel), 2 coaxialcomponent video switching (2 in, 1 out, 28MHz bandwidth)96kHz/24-bit DACsoptical digital output3 audio and 4 A/V (including 4 S-video and 1 front-panel) inputsno phono inputwide-range frequency response2 sets of main speaker outputs30 AM/FM presets16-9/16"W x 6-1/8"H x 16-3/8"D
