AUDIOINPUT/AUDIOOUTPUT–Therearetwotypesofaudioinputs.ThetopLEFT&RIGHTinputsare
RCA connectors for unbalanced signals, which are typically used for consumer products and musical
instruments. The bottom LEFT & RIGHT inputs are ¼” TRS (6.3mm) connectors for balanced signals,
whicharetypicallyused
forprofessionalproductssuch  asaudiomixers. TheOUTprovide sa loop‐thru
ofthesignalscominginontheIN.Thecrossoverfilter isactive ontheseoutputsastheyareintended
fortop speakers. NOTE: Homethea ter receiversmay featureadedicatedsingle cableSUBOUTorLFE
connection. Simply use the LEFT input on the  XD8s and set the crossover to BYPASS (as the AVR will
handlethelow‐frequencyfiltersintheaudiosignal).
POWER SWITCH & POWER CORD
–
Setthe power switchto ‘ON’ position when the speaker system is
readyforuse.Auto‐Standbyactivatesafter30minutesofnoactivity.Standbydeactivateswhenitdetects
aninput signalhavinganamplitudeof‐50dBuorgreater.In quiet(low listeninglevel)situations,adjust
CROSSOVER – Adjust the upper limit (HPF) of the subwoofer’s
frequencyresponse.A ruleofthumbwhenusingsmallspeakers is
tosettheswitch to120Hz(XD3).Medium sizespeakersare setto
100Hz (XD4). Larger size speakers are set to 80Hz (XD5). BYPASS
willdisengagethefiltertothe
subwooferandisusedwithasignal
preprocessed connection (LFE). BYPASS will also disengage the
filtertothe¼”TRSandRCAOUT.NOTE:TheOUTprovidesaloop‐
thruofthesignalscominginontheIN.Thecrossoverfilterisactive
ontheseoutputsastheyareintended
fortopspeakers.
POLARITYSWITCH–Allowsthesignaltoinvertedinpolairtysothe
outputof thesubwoofer willblendinwiththemain speakers.Set
thePOLARITY switchto “0”. At thelisteningposition,listento the
midbassoutput.Ifitsoundsweak,setPOLARITYbackto“180.”
