hazard ous and invalidates all agency listings,
and may also void the product's warranty.
6. Do not operate the amplifier with the red Clip
LEDs constantly flashing.
7. Do not overdrive the mixer, which will cause
clipped signal to be sent to the amplifier. Such
signals will be reproduced with extreme
accuracy, and loudspeaker damage may result.
8. Use caution when operating the amplifier with
a 2-ohm load impedance on 1 channel. Do not
operate the amplifier with less than a 2-ohm
load impedance per channel when driving
more than 1 channel. Due to the amplifier's
output protection, such a config uration may
result in premature clipping, speaker damage
or a blown power fuse.
Remember: Crown is not liable for damage that
results from overdriving other system compo nents.
