Audio EquipmentConnections
Werecommend t hatyou usehighquality interconnect
cables whenmaking connections t o sourceequipment
andrecorders t o preserve t he integrity o f the signals.
1. Connect t he analog outputof a CDplayer to the

Toensurethatallthe audiosignals arecarriedb your

selecting the propercable.
Regardless of thebrandof cableselected, werecom-
mendthatyouusecable witha gauge of 14 or smaller
Remember thatinspecifying cable, t helowerthe
number; thethickerthecable.
Cable witha gauge of 16 maybe usedforshortruns
of lessthan10 taet. W e do notrecommend t hatyou
usecables withanAWGequivalent of 18 or higher,
dueto the power lossanddegradation i npertormance
thatwilloccur:
Cables thatareruninside wallsshould havethe appro
priatamarkings t o indicate listing withUL,CSAor other
appropriate testingagency standards. QuesSons about
running cables inside walls shouldbe referred to your
installer or a licensed electrician w hois familiar with
the NEC and/ortheapplicable b uilding codesin
yourarea.
Whenconnecllng w ires b thespeakers, be certain
to observe proper p olarity. Notethatthe positive (+)
terminal of eachspeaker c onnecSon hasa specific color
code, a s noted on page8. However, mostspeakers
stillusea mdterminal f orthepositive (+) connection.
Connect the "negative" or "black" w ireto thesame
terminal on boththe receiver a ndthe speaker.
NOTE: W hilemostspeaker m anutacturers adhere to
an industry convention o f usingblack terminals f or
negative andredonesforpositive, somemayvary
fromthisconfiguration. Toensureproperphase and
optimal p erformance, consultthe idenllfication plateon
yourspeaker o r the speaker's manual to verifypolarity,
If youdo not know the polariS/of y ourspeaker, ask
yourdealerforadvice beforeproceeding, or consult
the speaker's manufacturer.
Wealso recommend thatthe lengthof cableused
to connectspeakerpairsbe identical. F orexample,
