15ENGLISHCONNECTIONSThere are different types of audio and video connections used to connectthe receiver, the speakers, the video display, and the source devices. TheConsumer Electronics Association has established the CEA® color-codingstandard.

They contain two wire conductors, or leads, inside plasticinsulation, that are differentiated in some way, such as with colors or stripes.The differentiation preserves polarity, without which low-frequencyperformance can suffer. Each speaker is connected to the receiver’s speaker-output terminals using two wires, one positive (+) and one negative (–).Always connect the positive terminal on the speaker, which is usually coloredred, to the positive terminal on the receiver, which is colored as indicated inthe Connection Color Guide above (Table 1). The negative terminals are bothblack.The AVR 760/AVR 660 uses binding-post speaker terminals that can acceptbare-wire cables.Bare wire cables are installed as follows (see Figure 2):Unscrew the terminal cap until the pass-through hole is revealed.1.Insert the bare end of the wire into the hole.2.Hand-tighten the cap until the wire is held snugly.3.Figure 2 – Binding-Post Speaker Terminals With Bare WiresSubwooferThe subwoofer is dedicated to the low frequencies (bass), which requiremore power. To obtain the best results, most speaker manufacturers offerpowered subwoofers that contain their own amplifier. Usually, a line-level(nonamplified) connection is made from the receiver’s Subwoofer Output toa corresponding jack on the subwoofer, as shown in Figure 3. The AVR 760offers the option of connecting two subwoofers to independent outputs,which enables the EzSet/EQ II process to configure each subwoofer preciselyto account for its unique characteristics and placement within the room.Although the purple subwoofer outputs look similar to full-range analogaudio jacks, they are filtered to allow only the low frequencies to pass. Don’tconnect these outputs to any other devices.Preout SubwooferFigure 3 – SubwooferconnectInG Source DeVIceSto tHe aVrAudio and video signals originate in “source devices,” including your Blu-rayDisc or DVD player, CD player, DVR (digital video recorder) or other recorder,tape deck, game console, cable or satellite television box, MP3 player, USBdrive or network device. The AVR’s tuner also counts as a source, even thoughno external connections are needed, other than the FM and AM antennas.Separate connections are required for the audio and video portions of thesignal, except for digital HDMI connections. The types of connections useddepend upon the capabilities of the source device and video display.audio connectionsThere are two types of audio connections: digital and analog. Digital audiosignals are required for listening to sources encoded with digital surroundmodes, such as Dolby Digital and DTS, or for noncompressed PCM digitalaudio. There are three types of digital audio connections: HDMI, coaxial andoptical. Do not use more than one type of digital audio connection for eachsource device. However, it’s okay to make both analog and digital audioconnections to the same source.NOTE: HDMI signals may carry both audio and video. If your video displaydevice has an HDMI input, make a single HDMI connection from eachsource device to the AVR. Usually, a separate digital audio connection is notrequired. Turn the volume on your television all the way down.
