ENGLISH8Speaker system connections• Connect the speaker terminals with the speakersmaking sure that like polarities are matched (< with<, > with >). Mismatching of polarities will resultin weak central sound, unclear orientation of thevarious instruments, and the sense of direction of thestereo being impaired.• When making connections, take care that none ofthe individual conductors of the speaker cord comein contact with adjacent terminals, with other speakercord conductors, or with the rear panel.Speaker Impedance• When speaker systems A and B are use separately,speakers with an impedance of 6 to 16 Ω/ohms canbe connected for use as front speakers.• Be careful when using two pairs of front speakers(A + B) at the same time, since use of speakers withan impedance of 12 to 16 Ω/ohms.• Speakers with an impedance of 6 to 16 Ω/ohms canbe connected for use as center and surround speakers.• The protector circuit may be activated if the set isplayed for long periods of time at high volumes whenspeakers with an impedance lower than the specifiedimpedance are connected.1. Loosen by turningcounterclockwise.2. Insert the cord. 3. Tighten by turningclockwise.NOTE:NEVER touch the speaker terminals when thepower is on.Doing so could result in electric shocks.System BFRONT SPEAKER SYSTEMSFRONT SPEAKER SYSTEMSSURROUND SPEAKER SYSTEMS• Precautions when connectingspeakersIf a speaker is placed near a TV orvideo monitor, the colors on thescreen may be disturbed by thespeaker’s magnetism. If this shouldhappen, move the speaker awayto a position where it does not havethis effect.Connection jack for subwoofer withbuilt-in amplifier (super woofer), etc.To achieve Dolby Digital (AC-3)playback effect, use a unit that cansufficiently reproduce frequenciesof under 80 Hz.Connecting the speaker cordsCDR /TAPECDR /TAPEDVD /VDPTV /DBSDVD /VDPTV /DBSVCR-1VCR-2VCR-1VCR-2VCR-1 FRONTFRONTPREOUTCENTERCENTERDVD/VDP TV/DBS VCR-1 VCR-2S-VIDEOVCR-1 VCR-2 MONITORSUBWOOFERSPEAKER SYSTEMSSURROUNDPHONOCDSIGNALGNDMONITORVCR-2VCR-1VCR-2OPT-2OPT-2OPT-1FLAMANTENNA TERMINALSLOOPANT.FMCOAX.75SLEXT.

The purpose of this circuit is to protect thespeakers under circumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows, when the temperature surrounding the unit becomes unusually high,or when the unit is used at high output over a long period which results in an extreme temperature rise.When the protection circuit is activated, the speaker output is cut off and the power supply indicatorLED flashes. Should this occur, please follow these steps: be sure to switch off the power of this unit,check whether there are any faults with the wiring of the speaker cables or input cables, and wait forthe unit to cool down if it is very hot. Improve the ventilation condition around the unit and switch thepower back on.If the protection circuit is activated again even though there are no problems with the wiring or theventilation around the unit, switch off the power and contact a DENON service center.Note on speaker impedance• The protector circuit may be activated if the set is played for long periods of time at high volumes whenspeakers with an impedance lower than the specified impedance (for example speakers with an impedanceof lower than 4 Ω/ohms) are connected. If the protector circuit is activated, the speaker output is cut off.Turn off the set’s power, wait for the set to cool down, improve the ventilation around the set, then turnthe power back on.
