A-Bus utilizes simple CAT-5 cable to provide audio source distribution up to 4 locations (expandable to 8) quickly and easily. Providing stereo audio amplification, along with complete IR routing and remote control ability, this system is the most efficient and versatile whole house audio system available today. The system only put out 6W per channel using the keypad amp.
You will need Cat 5 to run to each volume control, then run speaker wire to each in-wall speaker, or in-ceiling speaker. A-Bus is great for background music, but due to its limited power rating, it is not suitable for heavy note music (bass).
