3 Setup (continued)

3.7 Connect to AC Mains

Connect the AC power cordset of your amplifier to the AC mains power source (power outlet). NOTE: The plug supplied with 120V versions of the MA5000VZ is a 120V, 30-ampere plug (Figure 3.9).

MA5002VZ

NOTE: The third prong of this connector (ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.

Amplifiers don’t create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. You must operate your amplifier from an AC mains power source with not more than 10% variation above or below the amplifier’s specified line voltage and within the specfied frequency requirements (indicated on the amplifier’s back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.

Operation Manual

3.8 Startup Procedure

Use the following procedure when first turning on your amplifier:

1.Turn down the level of your audio source.

2.Turn down the level controls of the amplifier.

3.Turn on the “Enable” switch. The Enable indicator should glow.

4.Turn up the level of your audio source to an opti- mum level.

5.Turn up the Level controls on the amplifier until the desired loudness or power level is achieved.

6.Turn down the level of your audio source to its normal range.

If you ever need to make any wiring or instal- lation changes, don’t forget to turn off the amplifier and disconnect the power cord.

For help with determining your system’s opti- mum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

4.1Precautions

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 flashing.

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.

8.Never operate the amplifier with less than the rated load impedance. Due to the ampli- fier’s output protection, such a configuration may result in premature clipping and speaker damage.

Remember: Crown is not liable for damage that results from overdriving other system compo- nents
