SINGXER SA-1 V2 Balanced Headphone Amplifier Class A

It have a upgrade version: https://thehificat.com/en-fr/products/singxer-sa-2-fully-balanced-class-a-headphone-amplifier

Description

The Singxer SA-1 V2 is a high-performance headphone amplifier and preamplifier based on a Class A architecture with fully balanced discrete circuits. This updated version features an optimized circuit design for lower output impedance and increased thrust, providing an exceptional audio experience for audiophiles.

Features

  • Full Analog Amplifier: The SA-1 V2 is completely analog, avoiding EMI interference caused by digital control, ensuring pure audio signal transmission.
  • ROHM Input Transistors: Ensures very low noise and excellent performance, with an output stage utilizing multi-stage current amplification similar to high-power amplifiers.
  • High-Power Output: Each channel incorporates 2 pairs of ON Semiconductor 4A transistors for low internal resistance and high output power, with comprehensive protection against overcurrent, overload, short-circuit, and more.
  • Versatile Connectivity: The SA-1 V2 offers various inputs and outputs, including balanced XLR and unbalanced RCA inputs, as well as balanced 4.4mm jack, 4-pole XLR, and unbalanced 6.35mm jack headphone outputs. Additionally, it features unbalanced RCA and balanced XLR preamplifier outputs.
  • Impedance Selection: The front panel includes switches for selecting input source (RCA or XLR) and impedance mode (LOW-Z or HI-Z) to accommodate high-sensitivity or high-impedance headphones.
  • Optimized Circuit Design: The V2 version features an optimized PCB routing and DC bias design, enhancing DC performance and output capacity.
