平 衡 座 枱 式 耳 擴 連 前 級 | 4.4mm 平 衡 耳 機 輸 出
輸出功率高達3500mWx2，採用NFCA(Nested Feedback Composite Amplifier)電路
♬ ULTRA-HIGH PERFORMANCE NFCA BALANCED MODELES:
A50s uses the same NFCA (Nested Feedback Composite Amplifier) module from flagship A90.
Voltage Current hybrid feedback architecture along withUHGF(Ultra High Gain Feedback)technology provides excellent DC and AC performance.
♬ HIGH OUTPUT CURRENT DRIVE CAPABILITY:
It allows the amp driving low impedance headphones with ease.
Ultra-low noise of 0.3uV is miles ahead of the competition,giving an absurdly high dynamic range of 144dB and no audio noise and darkest background for the most sensitives IEMs.
♬ WIDE RANGE OF ADAPTATION TO HEADPHONES:
A50s has a high voltage swing of 42vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than 0.1ohm.
It easily drives power-hungry headphones with a wide range of different impedance.
