Features:

1.Ultra-low distortion: THD+N -120db @1khz A weighting 20-22khz, When outputting 50mv at low gain, THD+N still has -96db @1khz A weighting 20-22khz.

2.Ultra-low noise: At low gain, the bottom noise is 300nv RMS A weighted 20-22khz,the direct test value of AP2522 is 0.66uv, At maximum output, SNR and DNR are 147db.

3.SA-1 adopts a true four-way fully independent fully discrete Class A amplifier circuit design, pure analog amplifier circuit and pure analog control, without EMI interference caused by digital control, in order to faithfully restore the analog flavor of music.

4.The amplifier circuit adopts the class AB architecture developed by ourselves. The differential input tube adopts ROHM's ultra-low noise audio dedicated tube. The tubes are purchased in large quantities and then selected by manual precision matching to ensure the consistency of the differential tube. For other tubes, we use SMD twin tubes with excellent consistency to ensure better performance.

5.The final output circuit uses multi-stage current amplification, similar to the architecture of a high-power amplifier. Each channel uses 2 pairs of ON Semiconductor's 4A mid-power tube to output in parallel to ensure low enough internal resistance and strong driving force; it can be done calmly even in large dynamics.
       
6.Perfect protection functions: overcurrent, overload, overheating, short circuit, DC protection, start-up delay, and the output relay can be cut off immediately when shutting down.


Multi-function and multiple play methods:
1. Support single-ended balanced input, free switching.

2. Support multi-output interface, XLR 4-pin true balanced, 6.35 single-ended, 4.4 balanced interface; also supports single-ended and balanced output as a front-end mode.

3. Support high and low gain design, you can easily connect all kinds of earplugs, super sensitive earplugs, etc.

4.When the gain is high, you can push a variety of big headphones, including a variety of high-resistance moving coils, low-resistance flat panels, and even ultra-low sensitivity headphones such as KK Earphone.

5.Support high and low impedance output, suitable for high-impedance headphones when high-impedance, and low-impedance headphones that require high current.

6.Large balanced output power:
32Ω: 6480mW
120: 2000mW
600Ω:380mW
Volume: 234MM*170MM*46MM
