The AD2055 combines 100% discrete, pure class A signal amplifiers with state-of- the-art passive and active filter topologies. The AD2055's unique circuitry delivers very high resolution transient detail at the operational extremes of real world equalization demands. The AD2055 auto-bias DC servo loop control eliminates the need for all interstage capacitor coupling. The AD2055 breathes life into all musical performances!
