connect only line level input devices such as mixers and tape machines to this jack.

cluded detachable power cord. The power connection uses an I.E.C. type connector, use only
the supplied polarized AC power cord. Use only a power cord that matches this type of con-
nection. Be sure to only connect this unit to a power outlet that matches the printed power
label on the unit. Never use a power when the ground prong has been removed or broken off.
The ground prong is used to reduce the risk of electrical shock in case of an electrical short.
This cord is designed to fit in one direction only. Do not attempt to force a cord if it does not
fit, be sure the cord is being inserted properly.

the exact same type fuse, unless otherwise instructed, by an authorized American Audio

will void your unit warranty.

applied, be sure you have made all connections to the speaker. Remember to avoid damaging
pops to the speakers, the mixer is turned on first and turned off last.
