Overview
PT2358 9 Inputs, 7 Outputs Car Audio Processor DESCRIPTION The PT2358 is a multiple inputs audio processor designed for Car Audio purpose.
Using I2C interface controls all of the functions.
Thanks for highly integration most of peripheral sub-circuits and components, it provides up to 9 inputs and equips outputs includes front, rear channel outputs.
For highly enhanced audio performance and experience, PT2358 volume controller has Soft-Step function to eliminate click noise during volume step changes.
Adjustable input gain, adaptive loudness, subwoofer filter, treble and bass tone control are all included.
APPLICATIONS  Car Audio FEATURES  Operation voltage 6~10V  7 single-ended stereo Inputs  1 quasi-differential (QD) input for AUX  1 fully-differential (FD) input for Bluetooth® audio module.
 Input gain from 0 ~+15dB in 1dB step  Main volume gain from +15 to -79dB in 1dB step with Soft-Step function.
 Soft-Mute and Soft-Step function for preventing audible click during volume and sources changing.
 1 subwoofer output with 3-band crossover frequency selection and gain from +15 to -79dB in 1dB step  Tone Control (Bass and Treble): -15 to +15dB in 1dB step  Loudness: gain from 0 to -15dB in 1dB step  Mixing input with 50% mixing ratio for front speakers, gain from -79 to +15dB in 1dB step.
 4 independent outputs for front and rear speakers, output gain from +15 to -79dB with 1dB step  Controlled by I²C Interface  Low Distortion and Low Noise  48-pin LQFP package Tel: 886-66296288‧Fax: 886-29174598‧http://www.
