PRE90 Preamplifier + Ext90 Input Extender

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.

; Ext90 is an input extender with three balanced inputs and one analog input. Topping's products with an aviation connector can be connected to Ext90 to obtain more input interfaces. We believe Ext90 will bring you HIFI music experience and fun!; The Ext90 is a device that pairs exclusively with the Topping Pre90 and A90 Discrete, allowing the latter to take advantage of more inputs. Thus, by combining the devices, you have two single-ended RCA inputs and four balanced XLR inputs. Ideal to integrate an audio system with many sources.

; To the Topping's products with an aviation connector, connecting the extender Ext90 is equivalent to adding four input channel interfaces, and other functions remain unchanged.
