Macro-Tech MA-24X6 & 36X12 Power Amplifiers

3 Operation

3.1 Precautions

Your Macro-Tech Series 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 con- figured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties.

For information on wiring and configura- tion, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownau- dio.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.

4.Never connect the output to a power supply, battery or power main. Elec- trical shock may result.

5.Tampering with the circuitry, or making unauthorized circuit changes, may be haz- ardous and invalidates all agency listings.

6.Do not operate the amplifier with the Signal/ IOC LEDs constantly indicating an IOC con- dition.

7.Do not overdrive the mixer, which will cause a clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.
