Description

The ACS54 consists of four satellites and a subwoofer and is especially designed as a multimedia gaming amplified speaker system. It is used with computers that have sound cards which provide 3D (threedimensional) decoded audio outputs or with conventional computer sound cards. The sound card outputs for 3D audio outputs are usually marked as OUT 1 and OUT 2. The ACS54 has two inputs that are connected to these sound card outputs. The information provided from the computer outputs will activate the 4 satellite speakers and subwoofer so that you will hear sounds above and below you and approaching from every direction. The result is a real-life audio experience that surrounds the listener with sound in all three dimensions. The computer software will allow modifying the directionality of the sound.

If the computer you are using does not have the 3D sound card decoder, it is possible to install one. The supplier of the sound card will provide installation instructions and software.

If your computer only has a stereo sound card, the ACS54 can still operate as a stereo amplification system. In this instance only one input of the ACS54 will be used. All four satellites and subwoofer will be activated. The front and surround speakers on one side will be one stereo channel and the front and surround speakers on the other side will be the other stereo channel.

It is also possible to drive the ACS54 from a DVD player that has two analog outputs.
