Manufacturer: Singxer
ASIN: B08QMDM631
Item model number: SA 1
Ultra-low distortion: THD+N -120db @1khz A weighting 20-22khz, when the output is 50mv at low gain, THD+N still has -96db @1khz A weighting 20-22khz
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.
