PT2033 Overview
The PT2033 is an audio processor designed for versatile application, it includes 3 stereo input selector with internal gain, master volume control with low frequency loudness pensation, individual channel output volume adjust and tone control. If a system wants subwoofer signal output, traditional solution needs a lot of discrete ponents and OPAMP to consist of low pass filter; in the PT2033, just needs 2 capacitors...
