There is a Q Sound chip on CPS1.5 and CPS2 and other devices that support it. Stands to reason the amp would need a processor designed to decode the output from the board?You should open the case and take a picture of the PCB. Finally settle the score once and for all if there's some sort of mysterious Q-sound processing chip on there or if it's all just passive components.
Starts here:There is a dissertation of how Q sound works by one of the men who worked on the platform in another thread.
This is hilarious.There is a dissertation of how Q sound works by one of the men who worked on the platform in another thread. From memory there is no processor on the amp per se but rather the architecture is used to trick the ears into hearing different effects.
Then the conspiracy theorists came out and called the guy a liar more or less. Even though he worked on developing Q sound and had no reason to deceive anyone.
