To install the surround speakers on the wall
Sharp designed the surround speakers so you may hang them on the wall.
Be sure to use the correct type and size of screw, as shown below.
3/16" (5 mm)
Min. 7/8" (22 mm)
1. Drive one screw into the wall for each speaker, as shown in the illus-
tration.
Make sure that both the screw and the wall can support a load of 45 lbs. (20 kg).
Drive the screws, so the screw head extends about 3/16" (5 mm) out from the
wall.

Bi-amp system:
Each speaker unit has a built-in subwoofer (low frequency range) which is driven sepa-
rately from the woofer and tweeter (mid-to-high frequency range). Two independent
amplifiers which have individual frequency characteristics are used.
By amplifying separately the two frequency bands, clearer sound is achieved.

power cord of this unit into the AC outlet. If you plug in the unit first, the unit
will enter the demonstration mode (see page 15).
