Specification

SINGXER SA-1 V2 Balanced Headphone Amplifier Class A

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.
