Run four AES/EBU cables from the source to the subwoofer AES/EBU inputs 1, , and 4. Run the
cables from the subwoofer AES/EBU outputs 1, , and 4 to the digital audio inputs of the loudspeakers.
The cable that carries the LFE channel must be connected to the subwoofer input number 4.
7.1 Surround System with Subwoofer (AES/EBU Single-Wire)
This setup uses four AES/EBU cables to carry “7.1-audio”. “7.1” refers to seven full-bandwidth audio
channels and an LFE channel. All cables run to the subwoofer first, then from the subwoofer to the seven
loudspeakers. In this system there are five loudspeakers in the front (Left Front, Center Front, Right
Front, Left Front Extra, and Right Front Extra), two loudspeakers in the rear (Left Rear and Right Rear),
and the LFE Low Frequency Effects channel reproduced by the subwoofer. The AES/EBU digital audio
cables are numbered one to four. The AES/EBU subframe assignments and connectors to be used with
the subwoofer and loudspeakers are provided in the table below. The correct subframe must be selected
in each loudspeaker.
