The Ext90 is an expansion device for the Topping Pre90 preamplifier, which originally has one pair of RCA and one pair of XLR inputs. With the expansion unit, we can increase the number of inputs, giving us a total of two pairs of RCA and four pairs of XLR connections. The expansion allows us to connect a larger number of source devices to our system. The connection between the PRE90 and EXT90 is very simple, using the special cable provided in the package, which supplies power to the device and transmits audio signals. The selection between inputs is possible on the PRE90 preamplifier.
