Figure 9: AL1 SAT Module

AL1 Module (Figures 9 & 10)

The AL1 — Automatic Line-Level Switcher — module has a default input as well as a sensing input. When signal is detected at the sensing input, that signal is fed to the amplifier as well as its output jacks. At the same time a 12V DC control signal is present on the removable screw connector.

The sensing input has a sensitivity control as well as a delay adjustment which controls the time the module waits after the signal at the sensing jack subsides before switching back to the default input.

Figure 10 shows a 275 SE amplifier with the AL1 module in a restaurant installation. The module’s default input is connected to the house restaurant audio and the sensing input monitors the paging microphone. The output is feeding a second 275 SE that has the factory-installed BBE module.
