CTs Power Amplifi ers
Operation Manual
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.
4.1 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
con fi gured for proper operation, including
input and output wiring hookup. Improper
wiring can result in serious operating
diffi culties. For information on wiring and
confi guration, please consult the Setup
section of this manual or, for advanced setup
techniques, consult Crown’s Amplifi er
Application Guide available online at www.
crownaudio.com.
2. Use care when making connections, select ing
signal sources and controlling the out put
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.
