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.
