3.8 Connect to AC Mains

Connect your amplifi er to the AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the amplifi er; then, plug the other end of the cordset to the AC mains.

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.

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

3.9 Startup Procedure

Use the following procedure when fi rst turning on your amplifi er:

1. Turn down the level of your audio source.

2. Turn down the level controls of the ampli- fi er.

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

4. Turn up the level of your audio source to an optimum level.

5. Turn up the Level controls on the ampli- fi er 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 optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

4.1 Precautions

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

1.Before use, your amplifi er fi rst must be confi gured for proper operation, includ- ing input and output wiring hookup.

Improper wiring can result in serious operating diffi culties. For information on wiring and confi guration, please consult the Setup section of this manual or, for advanced setup tech- niques, 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.Never connect the output to a power supply, battery or power main. Electrical shock may result.

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

6.Never operate the amplifi er with the red Clip LEDs constantly fl ashing.

7.Do Not overdrive the mixer, which will cause a clipped signal to be sent to the amplifi er. Such signals will be repro- duced with extreme accuracy, and loud- speaker damage may result.

8.Never operate the amplifi er with less than the rated load impedance. Due to the amplifi er’s output protection, such a confi guration may result in premature clipping and speaker damage.

9.XLS Series amplifi ers feature a built-in Anti-Clip Limiter which, when selected, will provide a high degree of protection against amplifi er clipping. Crown rec- ommends activating the limiter whenever sensible operation of the system cannot be ensured.

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