CTs Multi-Channel Power Amplifiers
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 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.
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-
figured 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, 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.
