With the help of maximum gain +16 dB, Pre90 could amplify the weak audio signal to acceptable level next amplifier.  What need to be mentioned is that since the noise is as low as 0.3uVrms, this step does not bring in audible noise while amplifying the signal.

 

Ext90 could expand you more inputs. A standard Pre90 provide you 1 x RCA and 1 x XLR stereo inputs. But when it working with a Ext90, they could provide totally 2 x RCA and4 x XLR stereo inputs. This is convenient for multi source systems. These combo allows you to connect up to a six more additional inputs to the D90/A90 stack.

Pre90 equips the similar NFCA (Nested Feedback Composite Amplifier) module from the flagship headphone amplifier A90. With UHGF (Ultra High Gain Feedback) technology, it provides excellent DC and AC performance and an absurdly high dynamic range of 145dB and no audible noise background. Pre90 uses relay volume control, brings the advantages of precise control, remote control, longevity, and complete channel balance.

 

Pre90 is added a volume memory function and also a safe volume function. If the volume was set high while turn on or switch in, Pre90 will automatically reduced to a safety volume level to avoid your speakers/headphones and your ears blown by sudden high volume. When the memory volume is called, if it is higher than the set safety level, it will be muted first, let you press OK to call it or press VOL + to gradually adjust it.
