Unpacking Your Mythos STs

Please Inspect For Shipping Damage

Each loudspeaker leaves our plant in perfect condition. Any visible or concealed damage most likely occurred in handling after it left our plant and should be reported at once to your Definitive dealer or the delivery company that delivered your loudspeaker. Please unpack your system carefully. Save all cartons and packing materials in case you move or need to ship your system. Record the serial number found on the back of the Mythos ST in the appropriate place on your warranty card, answer all questions and send it in.

Base Installation Instructions

Tools required: 4mm (or 5/32") Allen Wrench (also called Hex Key driver)

Parts required: Polished Granite Base, Cable Clip for AC Cord, four allen head bolts, eights plastic washers

Instructions:

1.Carefully lay the Mythos ST on its side. Lift the base of the speaker about six inches and support it with a soft padded object, such as a pillow. Do NOT support the speaker with a hard object, as you might dent or scratch the aluminum finish.

2.Place one plastic washer on each bolt.

3.Insert the bolts into the granite base from the same side that the black feet are attached to.

4.Place another plastic washer on each bolt so the washer is against the granite.

5.Finger tighten all four bolts into the threaded holes on the bottom of the Mythos. If this has been done correctly, washers will be between the metal surface of the Mythos ST, the granite, and the heads of the bolts.

6.GENTLY tighten each bolt with the allen head wrench. Do NOT overtighten or you may crack the granite.
