Headphone Amplifier Preamplifier Class A Balanced

Singxer SA-1 Amplificateur Casque Préamplificateur Symétrique

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 4.4mm jack and 4-pole XLR balanced, and 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).

Test du Singxer SA-1 par Audio Science Review (Amir)

" Clearly the Singxer SA-1 is designed using instrumentation to make sure it delivers extremely low levels of noise and distortion. While our testing is stressful enough to show a slight weakness in driving low impedance headphones, the unit is nevertheless worthy of top of the class designation in my book. "
