Product introduction:

  • The pre-amp is a high-quality fever preamp decoder designed by Tianyi Company for three years. It is mainly used with Tianyi AD1PA
  • It can also be used for pre-upgrade of AD2SE by setting AD2SE to the post-level mode and AD1PRE for its external pre-stage decoding.
  • Improvement can be seen immediately. The overall performance has changed dramatically.
  • 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 adopts the ESS9028Q2M of the American ESS company, which has the signal-to-noise ratio of 129dB and the distortion as low as -120dB.
  • The I/V conversion circuit op amp uses TI’s Ding-class fully differential op amp OPA1632 to maximize the high fidelity performance of the balanced transmission signal;
  • The electronic volume chip adopts the JUSE Ding-class MUSES72320, and the indicators such as distortion, signal-to-noise ratio and resolution are extremely excellent;
  • The balanced-to-unbalanced circuit op amp uses TI’s Ding-class bipolar op amp OPA1612 with distortion as low as 0.000015% and noise density as low as 1.1nV/√ Hz;
  • The whole AD-1PRE is powered by analog power supply, which eliminates the interference of the switching power supply to analog audio.
