Pathos InPol2 Tube Hybrid Integrated Amplifier

The InPol2 is a completely balanced dual-mono configuration. This hybrid Class-A amp is 45 W and has a high bandwidth in a feedback-free layout. 

InPol (Inseguitore Pompa Lineare - Linear Pump Follower) is a Pathos patented system that allows for much greater output in pure Class A. This fully balanced circuit design uses a single solid-state component in follower configuration, with a high-current gain and voltage gain together.

The tube amplifier amplifies the input signal voltage, and InPol supplies the current to drive the loudspeakers without any further amplification. The technology allows an increase in the theoretical output in pure Class A of between 25% and 50%. Together with a low output impedance and a double InPol circuit, the amplifier offers a high damping factor for immense control over the loudspeaker drivers.
