PT2314E

Stereo Audio Processor for Home/TV Audio

DESCRIPTION

FEATURES

The PT2314E is an audio processor designed for

versatile application, includes 4 stereo input selector

with adjustable gain, master volume control with low

frequency loudness compensation, speaker output

attenuator and tone control. It is a good solution for the

home audio signal processing.

•

4 stereo inputs with gain selection, range from 0dB

to +11.25dB in 3.75dB/step

Master volume from 0 dB to -78.75dB in

1.25dB/step

Speaker attenuator for balance, range from 0dB to

-38.75dB in 1.25dB/step

•

Each channel output can be muted individually.

Low frequency loudness compensation

Bass and Treble control, range from -14dB to

+14dB in 2dB/step

Wide operation range (VDD=4V to 10V)

Low harmonic distortion, low noise

Improved and replace PT2314 and PT2314A

Due to the high reliability requirement from the audio

business, the PT2314E improves

both audio

performances and input surge current capability, these

causes the PT2314E is the best solution for the

cost-effective audio systems.
