D. Wiring Diagrams for 5000 Series Screen Systems:
The three models in the 5000-Series are always triamplied. Models 5671 and 5672 all use three power
amplier sections, while the 5674, due to the quadruple set of LF units, makes use of four amplier sections. All
aspects of frequency division, time correction, power response equalization, and room equalization are carried out
by the JBL model DSC260A digital controller. Pertinent wiring diagrams are shown in Figure 35A and B.
