Selecting the power tap (CF-4TX only):
Make sure the power amplifi er is turned off when adjusting the power taps or making
connections.
1. Select the desired power tap by turning the switch with a
fl at-ended screwdriver.
If you are using a 70 V system, the wattage ratings are:
16, 32, 64 and 128 W.
If you are using a 100 V system, the available wattage
ratings are: 32, 64, and 128 W.
Make sure that you do not overload the amplifi er. This may
cause overheating to the amplifi er, and possible damage to
your loudspeakers. To avoid overloading, make sure that the
selected taps on the loudspeakers add up to no more than
80% of the rated power of the amplifi er being used.
CF-4LZ Electrical Installation
Note:
Observe all local and national codes when installing the CF-4LZ clip-fi t bracket.
All connections to the loudspeaker must be made with the power amplifi er turned off.
Two wire crimps are included to make the connections.
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 red (+) input wire on the CF-4LZ.
2. Connect the A – terminal on the amplifi er to the black (–) input wire on the CF-4LZ.
The loudspeakers have a nominal impedance of 8 ohm. 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.
