PT2319 Datasheet | Princeton Technology

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.
