Connecting Your Speakers Disconnect the power cord from the wall outlet before making any connections. Speaker Connection Precautions Connecting the Speaker Cables The receiver allows you to connect two sets of speakers. When two sets of speakers are connected, you can select which speaker set outputs sound or use both sets to output sound simultaneously.
Connecting Antenna This section explains how to connect the supplied indoor FM antenna and AM loop antenna, and how to connect commercially available outdoor FM and AM antennas. The receiver won’t pick up any radio signals without any antenna connected, so you must connect the antenna to use the tuner. AM antenna push terminals FM antenna connector Connecting the Indoor FM Antenna The supplied indoor FM antenna is for indoor use only. 1 Attach the FM antenna, as shown.
Connecting Antenna—Continued Connecting an Outdoor FM Antenna Connecting an Outdoor AM Antenna If you cannot achieve good reception with the supplied indoor FM antenna, try a commercially available outdoor FM antenna instead. If good reception cannot be achieved using the supplied AM loop antenna, an outdoor AM antenna can be used in addition to the loop antenna, as shown.
Connecting Your Components Before Making any Connections Connecting a Turntable • Always refer to the instructions that came with the component that you are connecting. • Do not plug in the power cord until all connections have been properly made. • Do not bind audio cables with power cords and speaker cables. Doing so may adversely affect the sound quality. • To prevent interference, keep power cords and speaker cables away from the tuner’s antenna.
Connecting Your Components—Continued Connecting a Recording Component To connect recording components, such as cassette deck, MD recorder and CD recorder, use an analog audio cable to connect the receiver’s TAPE 1 or 2 IN L/R jacks to the cassette deck’s analog audio output jacks, and use another analog audio cable to connect the receiver’s TAPE 1 or 2 OUT L/R jacks to the cassette deck’s analog audio input jacks, as shown.
Connecting Your Components—Continued Connecting a TV or Other Component with an Audio Output Use an analog audio cable to connect the LINE 1/DVD IN L/R or LINE 2 IN L/R jacks to the analog audio output jacks on the connected component. When you connect a VCR, the video input from the VCR should be sent to the TV directly. With (Remote Interactive), you can control your -compatible Onkyo CD player, RI Dock, and so on with the receiver’s remote controller.
Connecting Your Components—Continued Connecting the Power Cords of Other Components The receiver has AC outlets on its rear panel that can be used to connect the power cords of other components that you intend to use with the receiver.
