2 Setup
2.7 Connect to AC Mains
Connect the AC power cordset of your amplifier to the AC mains power source (power outlet).
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.
2.8 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 ampli- fier.
3.Turn on the “Enable” switch. The Enable indicator should glow.
4.Turn up the level of your audio source to an optimum 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 installation changes, don’t forget to turn off the amplifier and disconnect the power cord.
For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Amplifier Appli- cation Guide, available online at www.crownaudio.com.
