Topping PRE90 Preamplifier Hi-Res Audio NFCA Features

• ► TOPPING Pre90 Preamplifier ► Pre90 adopts full balanced structure, which can handle balanced and single-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 the normal preamplifier usetage, Pre90 can be used for "balanced to sin-gle-ended"or "single-ended to balanced"signal conversion.

• ► Selectable XLR / RCA output ► The output of Pre90 could be config to “XLR only”, "RCA only" or "XLR + RCA ". Therefore, the amplified signal can be connected to two different amplifiers. Good combination with EXT90 D90.

• ► Ultra-high Performance NFCA modules ► Pre90 uses the similar NFCA ( Nested Feedback Composite Amplifier )module from flagship A90 Voltage Current hybrid feedback architecturelong with UHGF ( Ultra High Gain Feedback ) technology provides excellent DC and AC performance. Ultra-low noise of 0.3uv is milesahead of the competition, giving an absurdly high dynamic range of 145db and no audible noise and darkest background.

• ►Relay volume control ► A large number of high quality Japanese small signal relayIsed fovolume control of Pre90. Brings the advantages of precise control remote control, longevity, and complete channel balanceIf the volume was set high while turn on or switch in, Pre90 will automatically reduced to a safe volume to avoid your speakers/headphones blown by sudden high volume.

• ► Ext90 could extend 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 and 4 x XLR stereo inputs. This is enough for multi source systems.

About Topping PRE90 Preamplifier Hi-Res Audio NFCA

► TOPPING Pre90 Preamplifier ► A wire with amplification: An excellent preamp should have top performance, just like a wire that can 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 the weak 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 not bring in audible noise while amplifying the signal." Safe Volume, so you don't get shocked: The safe volume feature on Pre90 will kick in when the saved volume ofle target input or output exceeds the set safe volume, and reduce thoutput to safe volume, protecting your expensive equipments and yourpriceless hearing. The safe volume function can be turned off in thesettings. "Volume memory for every input or output Pre90 could set volume memory for each input or volume memory for each outpout. When multiple inputs with different signal strengths are connected, switching the input often requires re-adjusting the volume at the same time. Pre90 can set volume memory for each input, and automatically adjust to the last volume setting when switching to that input. lf Pre90 was set volume memory for each output, then the volume of ""XLR output only"", ""RCA output only"", and ""XLR+RCA output"" will be memorized to adapt to the needs of different amplifiers. *Pre90 can only be set to memorize input volume or memorize output volume, not both."
