Either set of terminals may be used when congesting woofers. To the right are two application diagrams to help plan your sub woofer system installation, Figures 3 and. 4 show. how-to.
Application S — T541a The 75412 can be set up for stereo d-channel, Se channel or bridged 2-channel operation, ss shown in Figures 7 through 9. FRONT REAR one seven ope severe mC NOTE: For simplicity, Figures 7 through 9 do not show power, remote and input connections. NOTE: Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms.

INSTALLATION AND SETUP SETTING THE CROSSOVERS) Determine your system plans and set the crossover-mode switch accordingly. If your system design does not include a sub woofer, set the crossover more to FLAT and skip to "Setting Input Sensitivity” MORE SWITCH Hat: Allows z full-range signal through to the speakers; van be used with larger full-range speakers such as 6° % 2's.
