Incomplete connections will result in thegeneration of noise.• Use the AC OUTLETS for audio equipment only. Do not usethem for hair driers, etc.• Note that binding pin plug cords together with AC cords or placingthem near a power transformer will result in generating hum orother noise.• Noise or humming may be generated if a connected audioequipment is used independently without turning the power of thisunit on. If this happens, turn on the power of the this unit.Connecting the audio components• When making connections, also refer to the operating instructions of the other components.CD playerConnecting a CD playerConnect the CD player’s analog outputjacks (ANALOG OUTPUT) to this unit’s CDjacks using pin plug cords.Connecting a turntableConnect the turntable’s output cord to the AVR-3805’s PHONO jacks, the L (left) plug to the L jack,the R (right) plug to the right jack.NOTE:This unit cannot be used with MC cartridgesdirectly. Use a separate head amplifier or step-uptransformer.If humming or other noise is generated when theground wire is connected, disconnect the groundwire.Turntable(MM cartridge)Ground wireConnecting the pre-out jacksUse these jacks if you wish to connect external power amplifier(s) toincrease the power of the front, center and surround sound channels, orfor connection to powered loudspeakers.To use Surround back with one speaker, connect the speaker toSURR. BACK L CH.AC OUTLETS• SWITCHED(total capacity – 120 W (1 A.))The power to these outlets is turned on and off in conjunction with thePOWER operation switch on the main unit, and when the power is switchedbetween on and standby from the remote control unit.No power is supplied from these outlets when this unit’s power is at standby.Never connect equipment whose total capacity is above 120 W (1 A.).NOTE:Only use the AC OUTLETS for audio equipment. Never use them for hairdriers, TVs or other electrical appliances.Connecting the AC OUTLETSAC CORDAC 120 V, 60 HzConnecting a tape deckConnections for recording:Connect the tape deck’s recording input jacks (LINE IN or REC) to this unit’s taperecording (CDR/TAPE OUT) jacks using pin plug cords.Connections for playback:Connect the tape deck’s playback output jacks (LINE OUT or PB) to this unit’s tapeplayback (CDR/TAPE IN) jacks using pin plug cords.CD recorder or Tape deckRoute the connection cords, etc., in such away that they do not obstruct the ventilationholes.MD recorder, CD recorder or other componentequipped with digital input/output jacksCD player or other componentequipped with digital output jacksConnecting the DIGITAL jacksUse these for connections to audio equipment with digital output. Refer to “Setting theDigital in Assignment”. (See page 39)NOTES:• Use 75 Ω/ohms cable pin cords for coaxial connections.• Use optical cables for optical connections, removing the cap before connecting.NOTE:If humming noise is generated by atape deck, etc., move the tape deckaway.TRIGGER OUTTurn the DC 12V voltage on and off for the individual functions.For details, see “Setting the Trigger Setup”.
