The specifications and details in this and related JBL publications are therefore subject to change without notice. 1 Amplifier Expansion Module BassLink 4sc CONNECTIONS Note: In order for the Phantom Center circuit to operate properly, the speakers and input wires MUST be connected in proper polarity! SPEAKER CONNECTIONS Connect the speakers to the FRONT and REAR screw terminals, observing proper polarity (Figure 3). Figure 3. INPUT CONNECTIONS You must connect full-range signal to all four inputs on BassLink II (if you are using the 4sc). Do not connect a subwoofer output to any of the inputs if you are using the 4sc. Connect the input signal wires according to Figures 3a through 3d. If your source unit provides only speaker-level output wires, connect those wires to the Universal Interface connections as shown in Figures 3a or 3b. If your source unit provides line-level outputs with RCA-type connectors, connect the signal cables to the FRONT and REAR LINE LEVEL inputs as shown in Figure 3c or 3d. Note: If your source unit provides two line-level outputs and two speaker-level outputs, you may connect the line-level output to the appropriate (front or rear) RCA-type input and the speakerlevel outputs to the other (front or rear) Universal Interface connector. 3a.
