cable to the input signal ground. This may
form a ground loop and cause oscillations.
4. WARNING: Never connect the output
to a power supply, battery or power
main. Electrical shock may result.
5. Tampering with the circuitry, or making
unauthorized circuit changes may be
hazard ous and invalidates all agency listings,
and may also void the product's warranty.
6. Do not operate the amplifi er with the red Clip
LEDs constantly fl ashing.
7. Do not overdrive the mixer, which will cause
clipped signal to be sent to the amplifi er. Such
signals will be reproduced with extreme
accuracy, and loudspeaker damage may result.
8. Use caution when operating the amplifi er with
a 2-ohm load impedance on 1 channel. Do not
operate the amplifi er with less than a 2-ohm
load impedance per channel when driving
more than 1 channel. Due to the amplifi er's
output protection, such a confi g 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.
