General Description

The PT2347 is an audio processor designed for versatile application, it adopts all of functions from successful predecessor- the PT2313L, and it includes 3 stereo input selector with adjustable gain, master volume control with low frequency loudness compensation, individual output attenuator and tone control.

In car audio applications, maximum power output of the audio set is measurement on saturated condition, it may not achieve the goal if power amplifier does not have enough gain, therefore, the PT2347 provides extra +10dB voltage gain in final output stage, it is easy to drive the power amplifier into saturated power and eliminates external gain OPAMP.

Overview

PT2347 Stereo Audio Processor.

Key Features
