Advanced AL32 Processing Plus Denon constantly pursues innovative technologies to bring you the natural sound reproduction that your favourite music deserves. With this in mind, Denon's Advanced AL32 Processing Plus will deliver music that is accurate in the way the artist intended by utilising data interpolation algorithms, up-sampling, and bit-extension, the latest in analogue waveform reproduction technology to support hi-res audio. The PMA-1700NE plays back sources up to a high resolution of 384-kHz/32-bit. Denon technology The Denon PMA-1700NE has been designed to enable you to get the best sound no matter the source, this includes proprietary technology that only comes from 110 years of experience crafting high-quality audio equipment. The Advanced High Current single push-pull circuit provides two to three times more power than regular circuitry, transformers with individual wiring negate crosstalk and interference, electrical volume control with variable gain provides smooth linear control of levels and the six-block chassis configuration offers vibration-free performance and eliminates interference among circuits, preserving even the most delicate of signals. This ensures exceptional sound quality that is true to life. USB-DAC The USB-DAC function supports hi-res files up to 11.2-MHz DSD and 384-kHz/32-bit PCM. Any digital signals with suppressed jitter also pass through the high-quality DAC ensuring the purest of audio signals with complete precision. Source direct and analogue mode In the quest to achieve the cleanest signal possible that remains true to life, Denon includes a Source Direct function which bypasses all tone control for a pure signal from the source. On top of this, there is also an Analogue Mode that can be used to turn off the power and stop the operation of digital inputs avoiding any negative influence on your signal.
