4.1 Precautions

Your amplifier is protected from internal and
external faults, but you should still take the fol-
lowing precautions for optimum performance and
safety:
1. Before use, your amplifier first must be con-

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 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.
