Тема: PT2348 4.1-Channel Audio Processor with Subwoofer

Данный контент доступен только зарегистрированным пользователям.


The PT2348 is a 4.1CH audio processor designed for
Car Audio purpose. Using I2
C interface controls all of
the functions. Like most of audio processor, it
equipped up to 4 stereo sources input with adjustable
gain, master volume with adaptive loudness, treble
and bass tone control.
In a car entertainment system needs front and rear
seat individual control, the PT2348 provides separate
input source selection and output volume adjust ; a
special design mixing amp is very easy combine the
navigation system or cellular phone’s voice into the car
audio system.

FEATURES
• Controlled by I²C Interface
• 4 Stereo Inputs (including 1 quasi-differential input)
with selectable input gain
• 2 Channels Electronic Volume： +15 to -79dB with
1dB/step
• 1 Subwoofer Output: +15 to -79dB with 1dB/step
• Adjustable crossover frequency for Subwoofer
• Tone Control (Bass and Treble): -15 to +15dB,
1dB/step
• Input Gain Control: 0 to +15dB, 1dB/step
• Loudness: 0 to -15dB, 1dB/step
• 4 independent speaker outputs: +15 to -79dB with
1dB/step & independent programmable mix
input with 50% mixing ratio for front speakers
• Low Distortion and Low Noise
• 36-pin SSOP package

Re: PT2348 4.1-Channel Audio Processor with Subwoofer

Собрал схему, почему то у меня сам переключает бесконечно по кругу bass treble volume? даже при отключенных энкодере и pt2348.
Подскажите в чем проблема.

Re: PT2348 4.1-Channel Audio Processor with Subwoofer

Проверьте энкодер, на плате энкодера должны стоять 3 подтягивающих резистора по 10 К на +Uпитания. Кнопка энкодера инверсная, нажатие = GND

Всё отключено, подключён только дисплей. Пробовал на nano и mega. Везде одинаково.

Без энкодера работать не будет

Re: PT2348 4.1-Channel Audio Processor with Subwoofer

SW энкодера нужно поддягивать на 10к к земле? Разобрался у меня на плате нет его, стоят только 2.

Переписываю код под OLED i2C 1306 экраны, для проекта. Выложу здесь наработки.
