2.2 Connecting to AC Mains

WARNING: The third (ground) prong of the supplied AC power cord connector is a required 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 a 10% variation above or a 15% variation below the amplifi er’s specifi ed line voltage range and within the specifi 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.

Packed with your I-Tech amplifi er is a clip that retains the power cord so it can’t pull out accidentally.

1.Locate the clip in a bag in the I-Tech packing carton.

2.Locate the IEC power connector on the back of the amplifi er. Above and below that connector are two slots. Stretch the ends of the clip and insert them into the slots (Figure 2.3).

3.Plug the power cord all the way into the amplifi er IEC power connector.

4.Pull the clip to the left and snap it onto the power cord.

2.3 Wire Inputs and Outputs

2.3.1 Wiring basics

•Always use shielded wire for input wiring. The higher the density of the shield (the outer conductor) the better. Spiral wrapped shield is not recommended.

•When using unbalanced lines keep the cables as short as possible. Avoid lengths greater than 10 feet (3 meters).

•Do not run the audio input cables together with the high-level wiring such as loudspeaker wires or AC cords. (This lessens the chance of hum and noise being induced into the input cables.)

•Turn the entire sound system off before changing any connections. Crown is not liable for damage incurred when any transducer or component is overdriven.

THE CHANNEL 2 INPUT IS IGNORED by default in Bridge Mono mode. It can be summed using the input source selector and used instead of Channel 1.

For additional information on audio input wiring please refer to the Crown Amplifier Application Guide available online at www.crownaudio.com. It contains helpful information on preventing unwanted subsonic frequencies, radio frequency interference, ground loops, and feedback oscillation.

When using network connections, pass the CAT 5 cable fi ve times through a ferrite core (Figure 2.4), available from Crown Audio Inc. This is to ensure compliance with emission regulations.
