3 Operation
3.1 Precautions
Your amplifier is protected from internal and exter- nal faults, but you should still take the following precautions 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, consult 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: Headphone jack supplies full output voltage. Always turn level down (full CCW) before listening through headphones; otherwise headphone or hearing damage may result.
D Series Power Amplifiers
5.WARNING: Never connect the output to a power supply, battery or power main. Electrical shock may result.
6.Tampering with the circuitry, or making unau- thorized circuit changes may be hazardous and invalidates all agency listings.
7.Do not operate the amplifier with the IOC LEDs constantly flashing.
8.Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accu- racy, and loudspeaker damage may result.
9.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 premature clipping and speaker dam- age.
Remember: Crown is not liable for damage that results from overdriving other system components.
