front edge of the cabinet. The peg should be stored in the clip when the amp
is being transported in order to avoid damage to the peg or nut. You may want
to use the lifter at all times in order to aim the high frequency output of the
speaker toward your ear so that you can better hear the amp.

Tweeter Switch

An on-off control for the tweeter is mounted in a recessed cup on top of the
cabinet just behind the rear panel. The tweeter is engaged when the switch
paddle is pointing toward the front of the cabinet. Try the unit with the tweeter
on and off to decide which sounds best to you.

Care

Acoustic Image combos and cabinets are made from lightweight but strong
materials. A little care will keep yours looking new for years to come. Use a
clean, dry cloth to clean the metal parts of the amplifier. The cabinet covering
can be brushed or vacuumed to keep it dirt and lint free.
Warranty and Repair
We stand behind our products with a full warranty of five years from the date
of purchase. Should a problem arise, please call us before returning your
amplifier or enclosure . Naturally, our warranty does not cover products that
