Delivering high-power, state-of-the-art surround sound at a price suited to modest budgets, Denon's AVR-485S provides 6 channels of discrete amplification to drive all the primary speakers in a 6.1 surround sound system (front left/right speakers, rear left/right surrounds, and front/rear center speakers, along with a preamp output for the ".1" low-frequency effects channel, i.e. subwoofer). It's perfectly compatible with 5.1 speaker configurations--just leave of the rear center speaker. The receiver packs 110 watts per channel into 6 ohms (at 1 kHz with less than .7 percent total harmonic distortion).
You'll never be at a loss for creative surround algorithms, irrespective of your listening source. The receiver's onboard 6.1-channel surround processing includes Dolby Digital Surround EX, DTS 5.1, and Dolby Pro Logic IIx (for cinema, music, and games). Dolby Pro Logic IIx processing is the first technology to offer a choice of processing traditional stereo music and movie content into room-filling 5.1 or 6.1 channels.
The AVR-485S owes its high sound quality to premium digital-audio technologies like Melody 32-bit DSP from Analog Devices, whose 24-bit/192 kHz high-resolution DACs ensure premium playback sound from all 7 channels. If you're not listening in true surround sound at first, the receiver offers virtual surround for use with 2-speaker setups. Separate A and B speaker outputs (left/right only) let you power speakers in a second room.
The AVR-485S features 3 assignable sets of component-video inputs and 1 set of monitor inputs (all with 30 MHz bandwidth). You get 4 sets composite and 3 S-video inputs, a set of 5.1 external wide-bandwidth (100 kHz) inputs for multichannel formats such as DVD-Audio and Super Audio CD, 2 assignable digital inputs (1 optical, 1 coaxial), and a total of 6 analog inputs (not including the unit's built-in AM/FM tuner).
Product Description:
Home-Theater surround sound is only as good as its delivery system will allow. There are alot of home-theater sound systems out there but which, at what price point, will deliver the best performance value? For optimum Dolby Digital and DTS reproduction, the AVR485S features high quality, wideband audio amplification, providing 75 watts of power output for each of its six main channels. A large capacity power supply includes a high current power transformer along with discrete power output devices on all six amplifier channels for the highest dynamic range and superb reproduction clarity. The power amp circuits of the AVR485S have been meticulously designed to reproduce exceptionally high sound quality with a wide frequency response from 10 Hz to 100,000Hz.
