research #2: 4ch volume control


research #2: 4ch volume control

using a digital potentiometer we can control the input volume for etch channel, to create a car speakers 4ch balancer and controller, all will be as a serial controlled module.

 

the pcb is allmost ready, files and schematics soon…

thanks to evgeny (aka: bradpilot) – for the pcb design & schematics from my ugly pen schematics..

will be eatching soon…

based on arduino atmega ( atmega168/328) – with arduino bootloader  – this board control 4 digital potentiometers (x9c104p) – with 4 pairs of input headers on one side an 4 pairs of headers for the output.. serial connumication to control the volume level digitaly.

picture of the pcb – work in progress:
