An incomplete connection will cause noise generation.o Einding the pin plug to the power supply cord, or setting the pin cord close to the power supply transformer willcause humming or noise, and should be avoided.o Connection to the speaker systemConnect the speaker system for the left channel (the left side as viewed facin! the front) to the L speaker terminal on theback panel, and the speaker system for the right channel into the R terminal. There are two sets of SPEAKERS terminals.lf only one speaker system is to be used, connect it to the SYSTEM (A) terminals.This terminal is for the remote power switch.

When connecting the speaker terminals to the speaker systems, make certain to connect the polarities correctly (+ to +and - to -). lf the polarities are incorrect when the two are connected, the center area of the sound will be lacking, thepositions of the musical instruments will not be clear, and the stereo directional sensitivity will be impaired.o During connection, be careful that the center wires in the speaker cords do not protrude from the terminals to contactany other terminal, and that the central wires in the separate speaker cords do not contact each other.o Speker impedanceo When the A and B terminal sets are to be used separately, the speakers that are to be connected should have a nominalimpedance of 4 to 16 ohm.o When the two sets (A + B) are to be used at the same time, use of speakers whose impedance is outside the range from 8to 16 ohm will result in malfunction. Be careful not to let this happen.o Speakers with a lower impedance may cause the protective circuitry to operate.Models for the U.S.A. and Canada only. (Case of UL sandardized articles)oNTllllrebt-qrq/WARNING!This amplifier produces a large power output at the speaker termi-nals, which means that a dangerous amount of energy is generatedand that there is the danger of electric shock. Please perform thespeaker cord connections correctly as follows.(Making connections that differ from the specif ied method may giverise to a shock hazard.)1) For the speaker connection cord. use a cord made with non-combustible insulation material with a VW-1 rating or a cord ofthe SPT-1 type or one with higher flexibility.2) Use a screwdriver to take the screws holding the speaker terminalcover out.3) Connect the speaker cord specif ied in 1) to the speaker terminals.4) Tie the speaker cord, then pass it through the cutout hole in thespeaker terminal cover.5) Install the speaker terminal cover removed in 2).For regular cords1. Remove the insulationfrom the end of eachcord.2. Twist the center wire-3. Turn the speaker ter-minal to loosen it,insert the center wireof the cord, and thentighten the terminal tohold the wire in place.For extra-large cords1. Remove the insulationfrom the end of thecord. Loosen and re-move the end of thespeaker terminal.2. Insert the center wire,and bend back the wire.3. lnsert the cord in theterminal, and turn theterminal to the right totighten it.)lSPEAK E B /r/SYSTEM (B)SPEAKERSYSTEM (A)SPEAK ERTERM INALCOVERNote:The knob on this speakerterminal can be removedfrom the Amplif ier.

Are all the connections correctly made?2. ls the set being operated properly in accordance with the Operating Manual?3. Are the speakers and preamplifier being operated correctly?lf the set does not operate properly, perform the checks indicated in the flow chart below.lf none of the items listed apply to the difficulty, the amplifier is probably out of order. Turn off the power immediately andcontact the outlet where you purchased the amplifier or your nearest DENON dealer.Ar th indica-tors for POwERand SPEAKERSA or B lit?Chck tho con-nections of theBEM OT E P L U GCOR D.li tho PRo-TECTOR LAMPbllnki ng?lr th powor rup-ply cord com-pl.t.ly pluggpdinto the rock6t?Ara th speakercords connectdcorr6ctl y7ls the volumeknob 3et to thocorract position?Adiutt thvolume knob toa suitabl levol.Chsck wh6thorthe st vonti I a-tion is suffici6nt.Connect thsinput iackspropeily.Ars the inputjacks connectdproporly?ls thers no DCvoltage outputfrom the devicaconncted to th eL CH input side?Check the pre-amplif ier.ls th6 pre-amplifier normal?ls there no DCvoltag outputfrom th6 devicconnected to theR CH input sid7ls the state re-l6ased when thePR O T EC T O Rbutton ispressed?Ara ths speaksrcords normal?Power ampmalfunctionIt the sat is not oporating proper-ly, perform the checks indicatedin this flow chart.I,l3lOCK DAGRAMINPUTSELECTORSEMICONDUCTORSolCNJM-2O68DA (JRC)NJft82DTIBD (JRCIM5218P (MitsubishilVOLTAGEAMP LI -FICATIONIOTAL DISTORTION SERVO 8 DC SERVONchFINAL STAGEPOWER TRANSISTORSE (Emitter)C (Collector)B (Base)c0tiTR0L+80vE-80v+80v-80v+?4V+t4vEHDl4OO1 BP(HiachilOUTPUT- II NVERTI NGI NPUT- INON INVERTINGINPUT-IV UUVEEOUTPUT-2INVERTINGINPUT-2NON INVERTINGINPUT_ 22SC3852.
