Setting the Turn-On Mode Switch

 

 

 

 

 

 

The Niles System Integration Amplifier® has three turn-on modes. Select which

 

mode you desire by sliding the mode switch. See Installation Considerations on

 

page 6 for more information about each of the turn-on modes. Audio sense is

 

the factory default setting.

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.

 

Control Output

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