Description

Specifications:

  • 4-channel analog audio input interface: 3-way unbalanced input (AUX, CD, DVD), 1 balanced input;
  • 5 digital audio input interfaces: OPT1, OPT2, COAX1, COAX2, USB;
  • Analog output interface: two sets of unbalanced outputs, one set of balanced outputs;
  • The digital receiver chip uses the AK4118 of AKM;
  • The DAC chip is ESS9028Q2M of ESS Company of USA, the signal-to-noise ratio of the chip is as high as 129dB, and the distortion is as low as -120dB;
  • The I/V conversion circuit op amp uses TI’s top-of-the-range fully differential op amp OPA1632 to maximize the high fidelity performance of balanced transmission signals;
  • The electronic volume chip adopts JRC’s top MUSES72320, and the high distortion requirements are achieved by indicators such as distortion, signal-to-noise ratio and resolution.
  • The balanced-to-unbalanced circuit op amp uses TI’s top-of-the-line bipolar op amp OPA1612 with distortion as low as 0.000015% and noise density as low as 1.1nV/√ Hz;
  • The whole machine is powered by analog power supply, which eliminates the interference of the switching power supply to the analog audio;
