Advanced Ultra-High Current MOS with Single Push-Pull Circuit
Advanced UHC (Ultra-High Current)-MOS technology utilizes a minimum number of high-current amplifier elements to balance advanced speaker-drive capabilities and improve sound quality. Advanced UHC-MOS offers power-supply performance superior to that of bipolar transistors and incorporates the sound quality advantages of MOS-FETs. in PMA-1600NE, Advanced UHC-MOS is provided in a single push-pull configuration that eliminates deviations in the amplification stage and balances high power with delicate musical details. This circuit masterfully reproduces the full sonic range, from the delicate musical nuances to powerful climaxes.
Six-Block Chassis Configuration and Direct Mechanical Ground Construction
PMA-1600NE's chassis is comprised of six independent blocks that house the phono equalizer and input circuitry, volume control circuitry, USB-DAC circuitry, amplification circuitry, power section, and the control section. The chassis constructed with 1.0mm-thick steel plates that protect the signal circuits from external vibration and eliminate the adverse effects of mutual interference among the circuits. The power section is positioned in the center of PMA-1600NE. With heat sinks on both sides, the well-balanced-mass construction occupies an ideal location to prevent unwanted vibration from affecting sound quality. In addition, the feet supporting the heavy weight of the power transformer, heat sinks, and chassis are made of ABS resin with rigid rib construction.
Advanced AL32 Processing Plus and 32-Bit/384kHz PCM Input
For digital input, PMA-1600NE employs Advanced AL32 Processing Plus, the latest version of Denon's analog-waveform reproduction technology that utilizes unique data interpolation algorithms and supports high-resolution 32-bit/384-kHz PCM. These algorithms interpolate points that should exist before and after the points in large quantities of data to achieve a smooth waveform close to that of the original signal. By carefully restoring data lost during digital recording, the resulting playback is highly detailed, free of interference, accurately localized, richly expressive in the lower range, and beautifully faithful to the original sound.
Total Purity: Digital Isolator and Analog Mode
PMA-1600NE is equipped with a high-speed digital isolator to eliminate adverse influences on sound quality caused by high-frequency noise from a USB-connected computer or from the PMA-1600NE's digital inputs. Since data is transferred magnetically via coils embedded in an IC chip, the input and output sides are electrically isolated. By isolating the signal line between digital audio circuitry and the D/A converter, adverse influences of high-frequency noise on analog circuitry after the D/A converter become eliminated. PMA-1600NE also adopted a dedicated secondary winding in the power transformer for the digital circuitry to shut out noise from the power source. During analog playback, Analog Mode can be used to turn off power to the dedicated digital power source and completely stop operation of the digital input circuitry to avoid any high-frequency influence to the analog section. Analog Mode also turns off the fluorescent display, allowing PMA-1600NE to operate as a purely analog amp. (During Analog Mode, USB-B, coaxial digital, and optical digital inputs are disabled).
High-Resolution USB DAC and MM/MC Phono Equalizer
PMA-1600NE provides USB-DAC functions that support high-resolution 11.2MHz DSD and 32-bit/384-kHz PCM. DSD transmission methods support ASIO native playback and DSD audio over PCM Frames (DoP). Since asynchronous transfer is controlled by PMA-1600NE's master clock rather than the clock of a computer, the transfer is free of jitter. PMA-1600NE also includes a phono equalizer that supports input from MM and MC cartridges. On PMA-1600NE, the MM/MC toggle switch was changed from a push type to a relay type, which shortens the pattern on the circuit board and makes signal loops smaller, allowing delicate analog signals to be amplified with greater purity.
