Description
The Singxer SA1 is an high-performance, full-featured headphone amplifier and preamplifier. Pure Class A design 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 is very complete. Single ended inputs (RCA) and balanced inputs (XLR). For the headphone outputs, the amplifier offers 4.4mm jack, balanced output and 4-pole XLR balanced output. The 6,3mm jack is singled ended output. The preamplifier outputs are unbalanced RCA output and balanced XLR outputs.
The headphone gain can be changed to fit any type of headphone. Low sensitive and high sensitive, they all match.
