Crown Audio CDI1000 Manual Do Utilizador

3.1 Precautions
Your amplifier is protected from internal and external faults, but you 
should still take the following precau tions 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, con sult 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.
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 unautho rized circuit 
changes may be hazardous and invali dates 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 sig nals will be reproduced with extreme 
accuracy, 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 pre mature clipping and speaker damage. 
Remember: Crown is not liable for damage that results from 
overdriving other system components.
9. Crown CDi amplifiers can directly drive 70V/high-Z loads. To 
configure your amplifier for this mode of operation, see Section 
4.1.6.
