Optical and coaxial digital inputs. Front USB port.With the digital inputs, you can use the Denon player as a standalone D/A converter (Supports PCM signals and sampling frequencies of 32-192 kHz). When you connect an iPod or USB memory (containing MP3 / WMA / AAC / WAV) audio files will be transmitted digitally. Denon's Advanced AL32 Processor and other high-quality-audio circuits let you enjoy a rich, satisfying sound. Denon’s Disc Drive Mechanism with S.V.H. Loader for SACD, CD and CD-R/RW playbackSince Super Audio CD rotates at high speed, the drive mechanism itself is a source of considerable vibration. To thoroughly suppress that vibration, the motor shaft in this player has been shortened as much as possible, and the drive motor has been placed close to the turntable. To eliminate such mechanical variations and ensure maximum accuracy and playability in signal playback, corrections have been made for each unit individually. A S.V.H. (Suppress vibration, Hybrid Construction) Loader of a hybrid construction combining different materials gives stability to the disc drive so that the disc can be read with utmost accuracy. DAC Master Clock design with low jitter oscillator and minimal Signal PathsSince the player supplies clock signals to each device, a master clock has been placed immediately adjacent to the D/A converter to achieve accurate D/A conversion with minimal time axis jitter. A new low jitter oscillator has also been adopted to generate the clock signals. This Denon Master Clock design ensures that sound is correctly localized and your sound space is thoroughly realistic. Signal paths have been made thoroughly simple and straight to ensure a pure playback sound. The minimization of signal paths prevents signal degradation between circuits. Vibration-resistant design with Direct Mechanical Ground ConstructionThe chassis has been designed throughout to eliminate the adverse effects on sound quality caused by subtle vibrations from the player's interior or by external vibrations from the speakers.
