The Denon PMA-1700NE is an integrated amplifier that delivers 140 watts per channel into 4 ohms. It uses an ultra-high current single push-pull power circuit, Advanced AL32 Processing Plus and an MM/MC phono equalizer. It is compatible with a wide range of speaker types and impedances.
Its USB-DAC supports PCM up to 384 kHz/32-bit and DSD up to 11.2 MHz. Advanced AL32 Processing Plus supports 384 kHz/32-bit sources and restores information lost during digital recording. The DAC suppresses jitter, and a high-speed digital isolator blocks high-frequency noise from a USB-connected computer or digital inputs.
The chassis has a six-block configuration with direct mechanical ground construction. It is built from 1 mm-thick steel plates and ABS resin with rigid ribs, which protects the signal circuits from outside vibration and from interference between circuits. Volume, balance and tone are controlled electrically, with a mechanism that gives smooth, linear control. Analog mode switches off the digital input circuitry to keep high-frequency noise away from the analog section.
