IMPORTANT NOTE REGARDING DISTORTION
If you hear distortion when the speakers are being driven at high volume levels, it’s because you’re driving (turning up) the amplier too loud
and not from driving the speakers with more power than they can handle. Remember, most ampliers produce their full-rated power well
before the volume control is turned all the way up! If your speakers distort when you play them loud, turn down the amplier.
IMPORTANT NOTE ON INTERNAL OVERLOAD PROTECTION
The subwoofers feature an internal overload protection circuit, which will turn the subwoofers off or down if overdriven or overheated;
after a few minutes, they will resume normal operation.
If you experience any difculties with your Mythos ST-Ls, try the suggestions described below. If you are still having problems, please consult
your Denitive Technology Authorized Dealer for assistance.
1. Make sure all your system interconnects and power cords are solidly in place.
2. Should you experience any level of hum or noise, try plugging the power cords into the same power outlet as your amplier.
3. The system has sophisticated internal protection circuitry. If for some reason the protection circuitry is tripped, please turn down your
system’s volume and wait ve minutes before trying the system again. If the amplier should overheat, the system will turn off until the
amplier cools down and resets.
4. Check to be sure that your power cord has not been damaged.
5. Check that no foreign objects or liquid have entered the cabinet.
6. If you cannot get the subwoofer driver to turn on, or if no sound comes out and you are sure the system is set up properly,
please bring the loudspeaker to your Denitive Technology Authorized Dealer for assistance, but please call rst.
