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 Your Speakers—Continued Connecting a Powered Subwoofer Using a suitable cable, connect the receiver’s PRE OUT: SUBWOOFER to the input on your powered subwoofer. If your subwoofer is unpowered and you’re using an external amplifier, connect the PRE OUT: SUBWOOFER to the amp’s input.
Connecting Your Speakers—Continued Configuring the Speaker Impedance In this model, the factory default for speaker impedance is “8 ohms.” When you change the speaker impedance setting, read “Speaker Connection Precautions” on page 13 carefully before performing the procedures below. Note: Be sure to minimize the volume level on the receiver before configuring the speaker impedance. 3 Use the Up and Down [▲]/[▼] buttons to select “1. Hardware set,” and then press [ENTER].
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. Connecting the AM Loop Antenna The supplied indoor AM loop antenna is for indoor use only. 1 Assemble the AM loop antenna, inserting the tabs into the base, 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 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 OUT L/R jacks to the cassette deck’s analog audio input jacks, as shown.
Connecting Your Components—Continued Connecting a VCR Use an analog audio cable to connect the VCR/DVR IN L/R jacks to the analog audio output jacks on the VCR, and use a video cable to connect the VCR/DVR IN V jack to the composite video output jack on the VCR. Then use an analog audio cable to connect the VCR/DVR OUT L/R jacks to the analog audio input jacks on the VCR, and use a video cable to connect the VCR/DVR OUT V jack to the composite video input jack on the VCR.
Connecting Your Components—Continued With (Remote Interactive), you can control your -compatible Onkyo CD player, RI Dock, and so on with the receiver’s remote controller. • To use , you must make an analog audio connection between the receiver and each audio component.
