Overview
DESCRIPTION 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 compensation, individual channel output volume adjust and tone control.
If a system wants subwoofer signal output, traditional solution needs a lot of discrete components and OPAMP to consist of low pass filter; in the PT2033, just needs 2 capacitors only.
The PT2033 combine the low pass filter inside the audio processor and user may determine low pass corner frequency by the capacitance.
Broader supply range emphasis support to every application.
