Power Status —
Installation Considerations
Proper Power Supply
You must connect a Niles 12vDC wall adapter (Niles FG00665) into
the switched AC power outlet of the preamp/receiver in your system.
Any 12vDC power supply with a minimum of 100mA current capaci-
ty can be substituted.
Extending the Cable
If you must extend the cable from the wall adapter to the IRP2+’s sta-
tus input jack be sure to maintain correct polarity. The tip of the plug
should be positive (+) and the sleeve negative (-). Any 16 gauge 2-
conductor cable can be used to extend the power status cable up to
200 feet.
Checking the Power Supply
It is possible to check the status power supply itself and any connec-
tions that were made to extend the cable by inserting the status plug
into the Power jack on the IRP2+. If the Power LED lights the status
power supply and connections are OK. If the Power LED does not
light check all connections and replace the power supply if necessary.
For more details on incorporating the IntelliPad please refer to the
IntelliPad’s users manual.

DC
Many compo-
nents, particularly
surround proces-
sors and digital
preamplifiers,
provide a low
voltage whenever
the component is
“on” rather than
in “standby”. For
the IRP2+ to cor-
rectly broadcast
power status you
must install an
optional Niles
OTI-512 Opto-
Isolated trigger
interface. The
OTI-512 will con-
vert 3-30 volts AC
or DC to 12vDC.
