It is also a multi-functional microphone preamp that can connect to an optional 192kHz A-D converter. The heart of the unit uses a Lundahl input transformer. Based on the original ISA 110, it inherits the circuit that has been consistently used for the past 30 years. The transformer has special sound characteristics and is difficult to emulate by other methods. In addition, the latest variable input impedance technology provides flexibility for all applications.
