CF-4TX Electrical Installation

Before the clip-fi t bracket is mounted to the wall, the electrical connections to your 

system should be made. Two wire crimps are included to make the connections.

Note: Observe all local and national codes when installing the CF-4TX.  

All connections must be made with the power amplifi er turned off.

The following examples of 70 V and 100 V connections show an EAW Commercial 

CAM160, a typical mixer/amplifi er. Its speaker-level output is a screw terminal strip, with 

outputs for 25 V, 70 V, 100 V, ground, and 4 ohm.

70 V connection example

1.  Connect the amplifi er’s 70 V terminal to the red (+) input wire on the CF-4TX.

2.  Connect the amplifi er’s GND terminal to the black (–) input wire on the CF-4TX.

3.  Select the power tap as shown on the 

next page.

100 V connection example

1.  Connect the amplifi er’s 100 V terminal to the red (+) input wire on the CF-4TX.
