3.1 Precautions

Your amplifi er 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 amplifi er fi rst must be
confi gured for proper operation, including
input and output wiring hookup. Improper
wiring can result in serious operating
diffi culties. For information on wiring and
con fi guration, please consult the Setup
section of this manual or, for advanced setup
tech niques, consult Crown's Amplifi er
Applica tion 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. WARNING: Never connect the output to a
power supply, battery or power main.
Elec trical 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
ampli fi 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.
