4.1 Precautions

Your amplifier is protected from internal and external
faults, but you should still take the following precautions
for optimum performance and safety:
1. Before use, your amplifier first must be configured
for proper operation, including input and output
wiring hookup and Stereo/Mono-switch setting.
Improper wiring can result in serious operating diffi-
culties. In Parallel-Mono mode, a jumper is used
between the red (+) Channel 1 and 2 output binding
posts. To prevent distortion and overheating,
remove this jumper for Bridge-Mono and Stereo
modes.
For information on wiring and configuration, please
consult the Setup section of this manual or, for
advanced setup techniques, consult Crown's Ampli-
fier 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.
4. Never connect the output to a power supply,
battery or power main. Electrical shock may
result.
5. Tampering with the circuitry, or making unautho-
rized circuit changes may be hazardous and invali-
dates all agency listings.
6. Do Not operate the amplifier with the ODEP LEDs
turning off.
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 loud-
speaker damage may result.
8. Do Not operate the amplifier with less than the rated
load impedance. Due to the amplifier's output pro-
tection, such a configuration may result in prema-
ture clipping and speaker damage.
Remember: Crown is not liable for damage that results
from overdriving other system components.
