Topping Pre90 Preamplifier & Topping Ext90 input extender 2*RCA+4*XLR NFCA FULL Balanced amplifier Relay low noise HIFI Preamp
Ultra-High Performance NFCA modules
Pre90 uses the similar NFCA (Nested Feedback Composite Amplifier)module from flagship A90. Voltage Current hybrid feedback architecturealong with UHGF (Ultra High Gain Feedback) technology providesexcellent DC and AC performance. Ultra-low noise of 0.3uV is milesahead of the competition, giving an absurdly high dynamic range of145dB and no audible noise and darkest background.
Fully balanced amplifier structure forboth balanced and single-ended signals
Pre90 adopts full balanced structure, which can handle balanced andsingle-ended signal processing. The output can be balanced,sin-gle-ended, balanced + single-ended.
With the balanced + single-ended two-way input, in addition to thenormal preamplifier usetage,Pre90 can be used for"balanced to sin-gle-ended" or "single-ended to balanced" signal conversion.
A wire with amplification
An excellent preamp should have top performance, just like a wire thatcan amplify signals. As you can see, Pre90 did it.
Amplify the weak audio signal to acceptable level
With the help of maximum gain +16 dB, Pre90 could easily amplify theweak input signal to acceptable level of next amplifier. It is worth men-tioning that since the noise is as low as 0.3uVrms, this step does notbring in audible noise while amplifying the signal.
Relay volume control
A large number of high quality Japanese small signal relays are used forvolume control of Pre90. Brings the advantages of precise control,remote control, longevity, and complete channel balance.
lf the volume was set high while turn on or switch in, Pre90 will automat-ically reduced to a safe volume to avoid your speakers/headphonesblown by sudden high volume.
