Set the center speakerbetween the front left and right speakers and no further fromthe listening position than the front speakers.• Consult the owner’s manual for your subwoofer for advice onplacing the subwoofer within the listening room.• If the surround speakers are direct-radiating (monopolar), thenplace them slightly behind and at an angle to the listeningposition and parallel to the walls at a position 2 to 3 feet aboveear level at the prime listening position.SurroundThe AVR-1706 is equipped with a digital signal processing circuitthat lets you play program sources in the surround mode toachieve the same sense of presence as in a movie theater.[1] Dolby Surroundq Dolby DigitalDolby Digital is the multi-channel digital signal format developedby Dolby Laboratories.Dolby Digital consists of up to “5.1” channels – front left, frontright, center, surround left, surround right, and an additionalchannel exclusively reserved for additional deep bass soundeffects (the Low Frequency Effects –LFE– channel, also calledthe “.1” channel, containing bass frequencies of up to 120 Hz).Unlike the analog Dolby Pro Logic format, Dolby Digital’s mainchannels can all contain full range sound information, from thelowest bass, up to the highest frequencies – 22 kHz. The signalswithin each channel are distinct from the others, allowingpinpoint sound imaging, and Dolby Digital offers tremendousdynamic range from the most powerful sound effects to thequietest, softest sounds, free from noise and distortion.2 Dolby Digital and Dolby Pro LogicNo. of recordedchannels (elements)No. of playbackchannelsPlayback channels(max.)Audio processingHigh frequencyplayback limit ofsurround channel5.1 ch5.1 chL, R, C, SL, SR, SWDigital discreteprocessing DolbyDigital encoding /decoding20 kHz2 ch4 chL, R, C, S(SW – recommended)Analog matrixprocessing DolbySurround7 kHz2 Dolby Digital compatible media and playbackmethodsSymbol indicating Dolby Digital compatibility:The following are general examples. Also refer to the player’soperating instructions.1: Please use a commercially available adapter whenconnecting the Dolby Digital RF output terminal of the LDplayer to the digital input terminal.Please refer to the instruction manual of the adapter whenmaking connection.2: Some DVD digital outputs have the function of switchingthe Dolby Digital signal output method between “bitstream” and “(convert to) PCM”. When playing in DolbyDigital surround on the AVR-1706, switch the DVD player’soutput mode to “bit stream”. In some cases players areequipped with both “bit stream + PCM” and “PCM only”digital outputs. In this case connect the “bit stream +PCM” terminals to the AVR-1706.w Dolby Pro Logic II• Dolby Pro Logic II is a new multi-channel playback formatdeveloped by Dolby Laboratories using feedback logic steeringtechnology and offering improvements over conventional DolbyPro Logic circuits.• Dolby Pro Logic II can be used to decode not only sourcesrecorded in Dolby Surround ( ) but also regular stereo sourcesinto five channels (front left, front right, center, surround leftand surround right) to achieve surround sound.SubwooferSurround speakersFront speakers60°MonitorCenter speaker[ As seen from above ]Front speaker2 to 3 feet[ As seen from the side ]Surround speaker120°LD (VDP)DVDOthers(satellite broadcasts,CATV, etc.)Coaxial Dolby DigitalRF output terminal1Optical or coaxialdigital output(same as for PCM)2Optical or coaxialdigital output(same as for PCM)Set the input mode to“AUTO”( page 17, 18).Set the input mode to“AUTO”( page 17, 18).Set the input mode to“AUTO”( page 17, 18).ENGLISH
