SA - π
Commentary

A phase inverter developed to compensate for the absolute phase distortion that occurs when the positive half of the waveform is replaced with the negative half of the waveform in the amplifier or converter in the recording / reproduction system.

By simply connecting SA - π to the tape path or between the preamplifier and the power amplifier and switching the switch, the phase can be inverted and distortion can be corrected.

Coloring is eliminated by using top-of-the-line electronic components and almost no feedback around the single-stage 3-pole tube signal phase inverter.

When inverted, the input is directly connected to the output.
