Connecting
Speakers to amplifier
Connect the speakers and subwoofer as shown below. Use the longer, 8 metre cables for the rear satellites, and the shorter, 2 metre cables for the
front speakers and the subwoofer.
On all speakers, connect the all-black cables to the black (-) terminals, and the cables with the white stripe to the red (+) terminals.
The subwoofer connects to the Sub terminal. All the other speakers are the same, so you can connect any speaker to any of the front right, front left,
rear right or rear left terminals.
Note: After connecting the
subwoofer, make sure you can
place it on the floor as this is
where it performs best.
