7.1 Channel Dobly Surround Sound Processor. PRO Logic 11x. It amplifies your gaming earphones/headphones. It adds extra Bass+Surround sound to your gaming experience. It gives it an extra punch to your gaming experience. Works great! Paid $89+tax new. Only used it for about a month, sold my PS4 so no use for it.
