For Control 24CT Micro and the Control 24CT MicroPlus, connect the negative input to the "Common" terminal and connect the positive input to the appropriate tap. The input pins correspond to the taps of the transformer indicated on the label above each connec- tor. For example, if the system is being driven from a 70V Distributed Line, and the 2W tap is the desired connection, the positive input would be made to the input marked "2W, Violet." The negative connection would be made to the "Common" pin.

On the Control 24C Micro, low impedance version, connect the negative wire to the "-" terminal and connect the positive wire to the "+" terminal.

All other pins are "No Connection."

Paralleling Input Terminals - It is common to run two sets of wires - one set is the input to the speaker and the other is the feed to the next speaker. In this case, simply par- allel the two sets of wires to the same terminals on the speaker's terminal block.

Step 4 - Add included metal strain relief as necessary. The Control 24C/CT Micro and the 24CT MicroPlus are equipped with two locations where the installer can affix strain relief con- nectors - one is on the back of backcan and one is on the side (for applications with shallow access). The location of these two attachment points is shown on the Product Feature Identification on Page 3. The installer can attach a wide variety of installer provided fittings to these points if the included equipment is not adequate for the particular installation. Refer to Figure 6 shows the strain relief INCLUDED with the Control 24C/CT Micro and Control 24CT MicroPlus.
