Singxer SA-1 V2 is the latest fully balanced Class-A amplifier from the brand. It offers a completely discrete analog audio circuitry to provide a superb sound signal amplification with ultra-low noise-floor and distortion.

Fully Independent Class-A Analog Amplification Circuit:-

Class "A" is a type of amplifier circuit that reproduces the whole signal wave resulting in a higher-fidelity output with no cross-over distortion. The Singxer SA-1 V2 features a true four-way fully independent, fully discrete Class-A amplification circuit design. It is a pure analog circuit with pure analog control without any EMI(Electro-Magnetic Interference) caused by digital controls. 

Fully Balanced Output:-

The Singxer SA-1 V2 is a fully balanced audio amplifier with balanced XLR signal inputs. The audio signal is then amplified using top-class amplification circuitry providing low-distortion and noise floor. For final output, the device features 4-pin XLR/4.4mm Balanced headphones output ports. For Pre-out the SA-1 V2 is equipped with XLR balanced line-out too.

The SA-1 V2 also features 6.35mm single-ended headphone output and RCA single-ended pre-amp line-out functionality.

Super-Clean Signal Amplification:-

The Singxer SA-1 V2 chipset features high-quality premium components that enable the device to provide a super-clean output with ultra-low harmonic distortion and noise ratings. The output has a THD N rating of -120dB @ 1kHz A-weighted. The output has a super-low noise floor even with sensitive pairs of IEMs and Headphones there is no sign of distortion or noise. All you get is a pitch dark background where the minutest of musical details pop out making the output full of life.

Circuit Protection:- 

Singxer has designed the internal audio circuitry of the SA-1 V2 to provide protection against electrical issues like overcurrent, overload, overheating, short circuit, Start-up delay, and more. So users can enjoy their music without worrying about power causing any trouble to the device.
