Topping A90 HIFI Headphone Amplifier Pre amplifier Balanced Output NFCA Modules 4-PIN-XLR 4.4 Balanced 6.35mm SE Output 7600mW x 2 Amplifiers
Headphone-amp & Pre-amp: The NFCA modules of A90 are not only able to drive the headphone but also apply to be the pre-amp. When it is in pre-amp mode, the 20ohm SE and 40 ohm balanced output impedance are widely suitable for various-power amplifiers Ultra.
Full balanced SE Headphone Output: A90 has three output headphone jacks of 4-PIN-XLR, 4.4 balancedand 6.35 SE to meet different usages.
3 Step gain setting & adapt to various sensitivities: A90 is equipped with three gain settings of -95dB/0dB/9.5dB for SE and-35dB /6.0dB/15.5dB for balanced. The SE 25Vpp / balanced 49Vpp high output voltage.
High output current drive capability A the amp driving low impedance headphones with ease: Ultra low noise of 0.2uV is miles ahead of the competition giving absurdly high dynamic range of 145dB and no audible noise and darkest background for the most sensitive IEMS.
Ultra-high Performance NFCA modules: A90 implemented the first member of the new NFCA(Nested Feedback Composite Amplifier) module series Voltage Current hybrid feedback architecture along with UHGF(ultra high gain feedback) technology rovide excellent DC and AC performance.
