Advanced Ultra High Current MOS Single Push-Pull Circuit: The Denon PMA-3000NE features a new generation of Advanced UHC (Ultra High Current)-MOS Single Push-Pull circuit design which combines with a differential 2-stage amplifier circuit to drive almost any speaker configuration with improved sound quality. To achieve impeccable balance between delicate details of music reproduction and vigor of low frequency sound, the PMA-3000NE is capable of delivering a massive current output in a single push-pull configuration to drive even the most demanding speaker and ensure superior linearity in the output stage. Denon engineers carefully constructed the amplifier circuit within the PMA-3000NE to secure a frequency response of up to 100kHz during applied use. The volume circuit suppresses noise in the amplifier, achieving high sonic resolution. The PMA-3000NE handles a wide, dynamic range of Hi-Res audio sources with tone control and power throughout.

• 8 Ohm Rating: 80 watts x 2 channels (@ 20-20kHz with 0.07% THD)
• 4 Ohm Rating: 160 watts x 2 channels (@ 1kHz with 0.7% THD)

High Precision Electrical Controls: The Denon PMA-3000NE embraces electrical volume, balance and tone controls while preserving the analog feeling of operation. Clever engineering offers the feel of an analogue volume knob while an MCU measures the position of the knob and converts that position to control the master volume digitally. This unique mechanism offers a smoother, more linear control of the master volume by adjusting the curve of the analogue volume control in the digital world. The same configuration is also used for Balance and Tone controls.

Robust Power Supply Circuitry: The PMA-3000NE is equipped with two transformers that have been mounted facing opposite directions in a leakage cancelling (LC) mount system to cancel mutual influences of magnetic flux, a source of noise, leaking from the transformers. Denon’s new, custom-designed, powerful large-capacity electrolytic capacitors have been used for rectification, and low-loss, low-noise, high-speed Schottky Barrier Diodes were used in the rectifier circuitry. This ensures a sufficient supply of clean current. To achieve a simple and straight circuit configuration, the connection unit between the diode unit and the block capacitor was removed to drastically shorten the current supply line to the power amp. Extremely thick OFC wiring material was used for the power line to reduce impedance.

6-Block Chassis Configuration w/ Direct Mechanical Ground Construction: Constructed with an aluminium top-panel, the PMA-3000NE chassis protects the signal circuits from external vibration and eliminates adverse effects of mutual interference among the circuits. It's configured with six independent blocks that house phono equalizer and input circuitry, volume control circuitry, USB-DAC circuitry, amplification circuitry, power section and the control section. With the power section at the center, solid aluminium feet that support the weight of internal components and heat sinks on both sides, the construction is well-balanced and prevents unwanted vibration.

Quad D/A Converter: Listen to your favorite Hi-Res audio content through the Denon PMA-3000NE's Quad 384-kHz/32-bit DAC section with the highest resolution in audio quality. The PMA-3000NE's Quad D/A converter uses the ESS Sabre ES9018K2M chipset that operates in a quadruple configuration for optimal high-grade sound. Each channel has two ES9018K2M chips working in a different mode to achieve the highest accuracy and best signal to noise ratio. The PMA-3000NE supports Hi-Res audio playback up to 32-bit/384kHz PCM and 11.2-MHz DSD.

• DAC Master Clock: To accurately synchronize digital circuits and the four audio DACs, the PMA-3000NE's Master Clock Design adopts a Dual Low Phase Noise Oscillator which positions the master clock immediately adjacent to the D/A converters (DAC) suppressing jitter and ensuring optimum precision in D/A conversion.
• Dual Clock Oscillators: In addition, the quality of the clock, which becomes the reference for semiconductor operation, is extremely important for ensuring that the digital audio circuitry performs at its maximum potential. The PMA-3000NE employs a clock oscillator to dramatically reduce phase noise that is can cause displacement of frequencies. The PMA-3000NE is further equipped with two clock oscillators, one for each sampling frequency (44.1-kHz and 48-kHz), that can be switched between the frequencies to thoroughly suppress jitter.

Compatible Audio Files: The Denon PMA-3000NE supports the following digital audio files via its USB-B, Optical, or Coaxial inputs.

Utltra AL32 Processing: The PMA-3000NE is equipped with Ultra AL32 Processing, the latest in analog waveform reproduction technology from Denon. Ultra AL32 Processing utilizes data interpolation algorithms and supports Hi-Res 32-Bit/384kHz PCM signal input. These algorithms interpolate points that should exist before and after the points in large quantities of data to achieve a smooth waveform that is close to that of the original signal. These algorithms upsample the bandwidth from the original content, smoothing out the waveform and improving sound reproduction. Ultra AL32 Processing doubles the processing bandwidth from the previous generation upsampling 384kHz content to 1.536MHz. By carefully restoring data that was lost during digital recording, the resulting playback sound is highly detailed, free of interference, accurately localized, richly expressive in the lower range, and beautifully faithful to its original sound.

Digital Isolator + Pure Mode: Combining the best of both the analog and digital world, the PMA-3000NE is equipped with a high-speed digital isolator circuit between both sections to avoid any interference from the digital world in the analog domain. The PMA-3000NE also features three independent power supplies to ensure complete isolation for each section and avoid any interference. When the PMA-3000NE is set to Pure Analog Mode it turns off all digital circuits for the perfectly clear sound reproduction of an analogue input signal. Pure Analog Mode also turns off the fluorescent display, allowing the PMA-3000NE to operate as a purely analog amp and remove any electrical disturbances that may adversely affect your listening experience.
