Operation Manual
3.1 Precautions
Your amplifier is protected from internal and exter-
nal faults, but you should still take the following
precautions for optimum performance and safety:
1. Before use, your amplifier first must be config-
ured for proper operation, including input and
output wiring hookup. Improper wiring can
result in serious operating difficulties. For
information on wiring and configuration, please
consult the Setup section of this manual or, for
advanced setup techniques, consult Crown’s
Amplifier Application Guide available online at
www.crownaudio.com.
2. Use care when making connections, selecting
signal sources and controlling the output level.
The load you save may be your own!
3. Do not short the ground lead of an output cable
to the input signal ground. This may form a
ground loop and cause oscillations.
3 Operation
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 unau-
thorized circuit changes may be hazardous and
invalidates all agency listings.
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 accu-
racy, 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 dam-
age. Operating with a 2-ohm load is not
recommended, as the amplifier might
shut down.
Remember: Crown is not liable for damage that
results from overdriving other system components.
