Denon's ultimate-performance 7.1-channel AVR-3805 surround receiver is a high-quality, high-value receiver that's loaded with sound-enhancing and image-preserving features, including the finest digital-to-analog and analog-to-digital converters. The receiver provides 7 channels of amplification (120 watts per channel, 8 ohms, 20 to 20,000 Hz, with less than 0.05 percent THD) to drive all the main loudspeakers in a 7.1 home theater surround system. Ensuring high power and stability, the component employs a huge power transformer and an oversized block capacitor. Of course, you get full compatibility with all the latest advanced audio formats, including 7.1-channel surround decoding of, among other formats, Dolby Digital Surround EX, DTS, DTS 96/24 5.1 for DVD-Video, DTS ES Discrete 6/1, DTS ES Matrix 6.1, DTS Neo: 6 Cinema & Music modes, and Dolby Pro Logic II/IIx (for cinema, music and games). Dolby Pro Logic IIx is the first technology to offer a choice of processing traditional stereo music and movie content into either 6.1- or 7.1-channel signals.
The AVR-3805 marks the debut of a significant Denon feature: Auto Set-Up calibration and Room EQ, making it easier to tailor the performance of the receiver for your specific home theater or music-listening environment. The AVR-3805 analyzes and calibrates 6 critically important speaker settings: connection, phase, size, channel level, time delay, and frequency response.
A feature called Room EQ corrects frequency response with an 8-band parametric equalizer and adjusts to the optimum soundfield, compensating for speaker and room capability issues. Auto Set-Up calibration and Room EQ requires the use of an optional microphone, either Denon's own DMS-305 or another compatible mic. You can disable both the EQ and Auto Set-Up features if you prefer calibrating the receiver in the traditional manner.
The AVR-3805 owes a big part of its great sound quality to its premium digital-audio technologies, such as Analo
