FUSE
Only use the type of fuse specified on the back of the amplifier in the triangle printed on the
side of the fuse carrier.
PROTECTING YOUR EQUIPMENT
Never increase the volume to such a level that the sound becomes distorted. Set the bass vo-
lume level using control on the subwoofer with the bass control on your amplifier set to
the mid-position. Be very wary of CD's marked "Mega-Bass", "Extended Bass" or the like as
they will have been mixed at very high volume and could damage your subwoofer at high
volume.
