Abstract
The present invention is a stereo PA amplifier that is mounted inside a desktop computer. It is powered by the computer's 12-volt power supply and receives its input via a stereo mini cable from the computer's audio line out. Standard 8-ohm, non-powered speakers are then hooked up directly to the board via its speaker connector board. The volume of the present invention is adjusted by the computer's volume controls. The device eliminates the need for an external stereo amp and external mixer, which thereby reduces the installation time, cost, interconnecting cables, and the space needed for the overall computer system, while at the same time providing quality sound.
