Pioneer A-50DAK Integrated Amplifier | Class D | Phono MM | ESS SABRE32 Ultra DAC
Pioneer A-50DAK Integrated Amplifier delivers high fidelity amplified sound with Class D Amplifier, ESSSABRE32 Ultra DAC and minimum signal interference circuitry design.
Pioneer has a considerable advantage over other manufacturers with unrivalled experience in digital amplifiers. Through extensive research, development, and component reviews, the latest High-Fidelity Class D amplifier on the power amplifier part achieved improved transmission efficiency, to reproduce a more expressive fine sound. The High-Fidelity Class D amplifier downsized the circuit and heat sink by introducing the “Direct Power FET” with a high-efficiency drive for the output element, and significantly reduced electric signal loss and resonance noise. The High-Fidelity Class D amplifier also enabled the installation of a large-capacity power supply, which enhances the rapid production and control of the quick-responding sound unique to the Class D amplifier, allowing you to enjoy “dynamic low pitch” music.
Pioneer’s “Direct Energy” concept is pursued to the utmost, with optimised power supply/output circuit blocks, as well as parts layout to reproduce clearer sound with reduced distortion. The resulting excellent signal transfer and high S/N ratio bring out the best musical reproduction from the integrated amplifier.
The windings for the power amplifier, pre-amplifier, and controls are each separated inside the power transformer to cut out noise interference. This allows even more realistic amplification of the audio signals.
High-performance 8ch ESS SABRE32 Ultra DAC is adopted on the A-50DA-K/-S. It features low noise and high S/N ratio that enable 4ch parallel drive for each channel at maximum 384 kHz. The result is clear and open, yet solid sound with superior audio quality.
The integrated amplifier allows direct USB connection with a PC. What’s more, the signal transfer is done with USB asynchronous transfer mode, which controls the transfer process by using its high-accuracy clock, ensuring high-quality sound reproduction. This eliminates jitter, reproducing master-quality sound with extremely precise audio signals. In addition to 11.2 MHz DSD, the unit supports LPCM with a sampling frequency of 44.1, 48, 88.2, 96, 176.4, 192, 352.8, and 384 kHz, and quantization bit rate of 16, 24, and 32 bits. Gold-Plated Inputs, Large Machine-Cut Speaker
High-grade parts are used for the integrated amplifier’s terminals to provide a stable connection for pure sound delivery. The A-50DAK/- S features machine-cut gold-plated brass speaker terminals, exclusive gold-plated input terminals, and an AC inlet with polarity indication. The durable brass speaker terminals are set apart to easily accommodate thick high-grade cables. The speaker terminal has a large resin base for additional safety.
Extra-thick 3.5 mm aluminium is used for the front panel, providing rigidity for a stable performance. The aluminium volume knob offers a solid, high-grade feel and style. The Input Selector, Balance, and Bass/Treble knobs are also made of aluminium.
