Niles SI-250 オーナーマニュアル

NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 1-760-710-0992

2 CHANNEL, BRIDGABLE POWER AMPLIFIERS

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.

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.

1.   Check the requirements of the device you 

want to control.

The control output has a maximum 
current capability of 12V DC 150 mA.

2.  Connect the 3.5 mm Jack to the control 

output maintaining proper polarity  
(tip = +).

Niles makes an accessory cable plug 
FG00933.

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.
