Precautions

Connecting Network Cables

When making connections to the control network and Dante ports, the included ferrites should be attached
to the network and Dante cables at the back of the amplifier as shown in Figure 6. Both a small and large
ferrite should be attached to each cable as shown.

Connecting to AC Mains

Connect your amplifier to the AC mains power source (power outlet) using the supplied AC power cord set.
First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the
cord set to the AC mains.
WARNING: 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.
Make certain the AC mains voltage and current ratings are sufficient to deliver full power to all amplifiers.
If the AC line voltage varies out of an acceptable range, the amplifier's power supply turns off and the blue
Power LED flashes. The amplifier will turn back on when the AC line voltage returns to safe operating levels.
DriveCore Install DA amplifiers utilize a universal power supply. The AC voltage requirements are
100V-240V~, 50/60Hz (±10%). If the voltage exceeds these requirements, the Power LED will flash and the
amplifier will stop passing audio until the voltage is within the requirements.

Startup Procedure

When first turning on your amplifier:
1� Turn down the level of your audio source.
2� Turn on the "Power" switch. The Power indicator should light.
3� Turn down the amplifier levels in Audio Architect, see "Channel Levels and Mutes" on page 35.
4� Turn up the level of your audio source to an optimum level. Ensure that at no point in the signal chain is the signal being clipped in any way.
5� In Audio Architect, turn up the amplifier levels to the desired level.
IMPORTANT: Before making any wiring or installation changes, 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.
Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:
1� Configure the amplifier for proper operation, including input and output wiring hookup. Improper wiring can result in serious operating difficulties. For information
on wiring and configuration, please consult "Wiring Input Connectors" and "Wiring Output Connectors" on page 4. For advanced setup
techniques, 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 invalidate all agency listings.
6� Do not operate the amplifier with the Clip LEDs constantly flashing.
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 loudspeaker
damage may result.
8� Do not operate the amplifier with less than the rated load impedance. Due to the amplifier'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 components.
