Electrical Installation
Note:
Observe all local and national codes when installing the loudspeaker.
All connections must be made with the power amplifi er turned off.
The following example of a low-impedance connection uses a EAW Commercial CAZ800
amplifi er. This amplifi er uses a screw-terminal output.
1. Connect the A + terminal on the amplifi er to the (+) screw terminal of the input
connector as shown.
2. Connect the A – terminal on the amplifi er to the (–) screw terminal of the input
connector.
The loudspeakers have a nominal impedance of 8 ohms. If you connect other
loudspeakers in parallel, make sure that the overall impedance does not drop below
the minimum required by your power amplifi er.
3. Plug the input connector into the back of the loudspeaker, until it clicks securely in
place.
