6. Do not operate the amplifier with the red Clip LEDs constantly
flashing
7. Do not overdrive the mixer, which will cause clipped signa l to be
sent to the amplifier. Such signals will be reproduced with extreme
accuracy, and loudspeaker damage may result
8. Do not operate the amplifier with less than the rated load
impedance. Due to the amplifier's output protection, such a
configuration may result in premature clipping and speaker damage.
Remember Crown is not liable for damage that results from
overdriving other system components.
