Setting the Turn-On

Mode Switch

The SI-1230 has three turn-on modes. Select the mode you want by sliding the mode switch. See Installation Considerations on page 14 for more information about each of the turn-on modes.

TIP: To conserve energy set the TURN ON mode to either AUDIO SENSE or TRIGGER INPUT. Use of the CONSTANT mode will prevent the amplifier from turning off when not in use wasting energy.

TURN ON MODE

AUDIO SENSE 3-30V

CONSTANTAC/DC TRIGGER INPUT

Slide the switch with either

your fingernail or 1/8”

The Control Output

This terminal provides a 12V DC signal suitable for triggering Niles automated switchers, some motorized screens, some electric curtain controls, etc. This voltage is present only when the amplifier is active or on. When the amplifier turns off, the 12V signal is off.
