Fostex HP-A3MK2 Overview

Building upon the success of the original, the Fostex HP-A3MK2 is a USB DAC that converts digital audio to analog audio. The unit is capable of handling up to a 32-bit, 192 kHz digital audio source from your computer's USB port. Additionally, the HP-A3MK2 includes S/PDIF optical I/O that supports 32 to 96 kHz / 32-bit.

The HP-A3MK2 features a dual RCA line output and a 1/4" headphone output that's powered by integrated headphone amplifier. The unit is USB bus powered regardless of input routing choice and does not have a separate AC input. The input and output routing is selectable by front panel selector buttons.

High-Quality Sound Reproduction
  • High-quality sound reproduction can be easily achieved by simply connecting a USB cable to a PC.
  • USB audio and optical digital audio signals from a PC can be converted to analog signals and output from the line output terminal and headphone output terminal.
  • When used as a USB DAC, it operates with the USB Audio 2.0 driver of the PC (Windows or macOS) and supports up to 32-bit/192 kHz. It can be used immediately after connecting the USB cable and performing simple settings.
ESS Technology DAC
  • ES9016K2M from ESS Technology is used as the DAC chip
  • The HP-A3 uses a high-quality DAC chip, and the supported sampling frequency has been greatly enhanced from 24-bit/96 kHz of the HP-A3 to 32-bit/192 kHz. This allows users to enjoy higher quality sound without sacrificing ease of use.
  • S/P DIF input is limited to a maximum of 96 kHz
Improved Analog Circuitry
The analog circuitry has been newly designed to match the higher supported sampling frequency, and has improved THD (Total Harmonic Distortion) and other performance features that are comparable to those of high-end products.
Gain Switch
  • The headphone output amplifier gain can now be switched between Hi and Lo positions, with the Hi position providing a 10 dB increase in volume over the Lo position.
  • The Hi position is effective for low-level input signals and can be used with a variety of playback sources.
