Audio Processor IC

PT2319

DESCRIPTION

PT2319 is an audio processor IC specially designed for high fidelity audio applications utilizing

advanced CMOS processing technology. Included in the IC are 5 stereo input signal ports, super bass

and bass/treble controls, volume control, balance/fader controls and muting.

The internal circuits of PT2319 have undergone meticulous adjustment to achieve the finest possible

audio quality. Extremely low signal distortion, strong signal driving ability, and clear dynamic peak and

level sound quality at any volume level distinguish PT2319 from other audio processors. PT2319 is the

ideal solution for audio systems catering to the most demanding audiophiles.
