Tips
• When you connect a 7.1 channel speaker system
with two surround back speakers, all the angles A
should be the same.
• When you connect a 7.1 channel speaker system
with two front high speakers, place the front high
speakers
– at an angle between 22° to 45°.
– at least 1 meter (3.3 feet) directly above the front
speakers.
• When you connect a 6.1 channel speaker system,
place the surround back speaker behind the
listening position.
• Since the subwoofer does not emit highly
directional signals, you can place it wherever you
want.
