4 Operation

4.1 Precautions

Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1.Before use, your amplifier first must be configured for proper operation, including input and output wiring hookup and Stereo/Mono-switch setting. Improper wiring can result in serious operating diffi- culties. In Parallel-Mono mode, a jumper is used between the red (+) Channel 1 and 2 output binding posts. To prevent distortion and overheating, remove this jumper for Bridge-Mono and Stereo modes.

For information on wiring and configuration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown's Ampli- fier 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.Never connect the output to a power supply, battery or power main. Electrical 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 ODEP LEDs turning off.

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 loud- speaker damage may result.

8.Do Not operate the amplifier with less than the rated load impedance. Due to the amplifier's output pro- tection, such a configuration may result in prema- ture clipping and speaker damage.

Remember: Crown is not liable for damage that results from overdriving other system components.
