• The SA-1V2 version is a modified model of the original SA-1, with several major improvements: 1. Adjust the output impedance, enhance the current output capability, low resistance output impedance of 0.25 ohms (balanced) and 1.1 ohms (single-ended); high resistance output impedance of 10 ohms (balanced) and 11 ohms (single-ended); balanced output port has more thrust; 2. Optimized PCB alignment and adjusted the DC bias design of the line to improve DC performance.
• Ultra-low noise: At low gain, the noise floor is 300nv RMS A-weighted 20-22khz (tested after amplification by LNA), the direct test value of AP2522 is 0.66uv, and at maximum output, the SNR and DNR are 147db.
• Support multi-output interface, XLR 4-pin true balance, 6.35 single-ended, 4.4 balanced interface; also supports single-ended and balanced output as pre-mode
• Supports high and low gain design. When the gain is low, you can easily connect various earplugs, ultra-high-sensitive earplugs, etc. (still can maintain inaudible noise floor); Blocking coil, low-resistance flat panel, and even ultra-low-sensitive headphones such as KK.
• Support high and low impedance output, suitable for high-impedance headphones when high-impedance, low-impedance headphones that require high current can be pushed; freely switch, you can enjoy powerful driving and controlling sound, you can also try loose and calm simulation taste.
