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.
