AC Power Considerations
Ensurethattheamplierispluggedinto
anoutletcapableofsupplyingthecorrect
voltagespeciedforyourmodel.
Unplugyouramplier’spowercord
fromtheelectricaloutletifitwillbeleft
unusedforalongperiodoftime.
Routethepower-supplycordsoitisnot

placeduponoragainstit,especiallyat
plugs,conveniencereceptacles,andthe

Beforemakingorchangingany

amplierandyourothercomponentsare
turnedOFF.Alsoturndownthevolume

SpeakerLevelconnections
Theamplier’sspeakerleveloutputs
canacceptspeakerwireswithbanana,
dual-banana, bare wire, pins or spade
terminals.Ifyouhavebananatypecon-
nectorsonyourspeakerwire,makesure
that you tighten the binding posts before
inserting.
Make sure that the negative speaker
wiresnevertouchthepositivewiresas
this will short out and possibly damage
youramplier.
MagneticFields
Werecommendthatyouplaceyour
subwoofer further than two feet away
fromyourTV,VCR,tapedeckorcom-
puter, so the speaker’s magnet won’t
distortthecolorsofyourTVpictureor
erase your video tapes, audio tapes or
computerdiscs.
