Top 8 Best Topping Pre90

TOPPING Pre90 Preamplifier Fully balanced amplifier structure for both balanced and single-ended signals. Pre90 could set volume memory for each input or volume memory for each output. More easy operation with the remote controller.. 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 It 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.. 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.. 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 speakersheadphones blown by sudden high volume..

Pre90 adopts full balanced structure. 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 orsingle -ended to balanced signal conversion.. 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..
