The Singxer SA-1 is a high-performance, full-featured headphone amplifier and preamplifier based on Class A architecture and discrete, fully balanced circuitry. Completely analog, there is no EMI interference from digital control to disrupt the audio signal. ROHM input transistors provide very low noise and excellent performance. The output stage uses multi-stage current amplification, similar to that found in a high-power amplifier. Each channel has 2 pairs of 4A ON Semiconductor transistors to ensure low internal resistance and high output power. These circuits also incorporate a complete protection system against overcurrents, overloads, short circuits as well as thermal protection, DC protection, and switch-on delay.
This SA-1 also has a complete set of connectors. The input is asymmetrical RCA and symmetrical XLR. For the headphone outputs, the amplifier offers a 4.4mm jack and 4-pole XLR balanced, and a 6.35mm jack unbalanced. On the preamplifier output side, the SA-1 provides an unbalanced RCA output and a balanced XLR output.
In order to fit any type of headphones or earphones, whether they are high-sensitivity or high-impedance models, the SA-1 offers a choice of gain (low or high).
Features: >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 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 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 is equipped with XLR balanced line-out too. The SA-1 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 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 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.
