LED TUBE INSTALLATION (OPTIONAL)
ThesePolkAudio amplifiershave beendesigned with
acustomheat sinkthat canaccommodate two
(optional—notsupplied)VARAD LEDtubes.
1.Before installingthe LEDtubes, removeand discard
themountingfeet fromthe VARADLED tubes.
2.Slide eachLED tubeassembly intoyour PolkAudio
amplifierheatsink. Ensurethat theLEDs arefacing
outforoptimal visibility.The wiresfrom theLED tube
assemblyshouldbe onthe signalinput endof the
amplifier.TheBlack wirefrom theLED tubeis ground
andtheBlack/White wirefrom theLED tubeis power.
3.Run thetwo wiresfrom thetube assemblyand
connectthemto the4-pin LED/FANinput connec-
tor.Referto theLED/FAN harnessdiagram given
earlierinthis manual.

SUBSONIC FILTER ADJUSTMENT
(PA1100.5 only)
Thisamplifieruses asubsonic filterto maximizethe perfor-
manceofa subwoofer.The subsonicfilter isa high-pass
filterthatremoves unwantedbass outputat verylow
frequenciesformthe woofer.This increasesthe output
ofasubwoofer byas muchas 3dB byincreasing the
mechanicalpowerhandling ofthe subwoofer.Depending
onthetype ofenclosure thesubsonic filtercan increase
theuseablelow frequencyoutput byan additional10dB!
Acceptableboostlevels aredetermined bythe type
ofenclosureused, wattageof theamplifier, andthe
subwoofer’sexcursioncapability.
Thefollowingguidelines shouldbe usedfor properset
upofthe subsonicfilter toprovide optimumperformance
