Connecting Your Speakers—Continued Speaker Connection Precautions Read the following before connecting your speakers: • You can connect speakers with an impedance of between 8 and 16 ohms. If you use speakers with a lower impedance, and use the amplifier at high volume levels for a long period of time, the built-in amp pro- tection circuit may be activated.
Connecting Your Speakers—Continued Center Speaker Base Use the center speaker base to mount the center speaker horizontally. If you place the speaker and its base on top of a TV or an entertainment center, adjust the angle of the speaker so that it faces toward the listening position. The center speaker should be installed on the base securely.
Connecting Antennas 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 AV receiver won’t pick up any radio signals without any antenna connected, so you must connect the antenna to use the tuner.
Connecting Antennas—Continued Connecting an Outdoor FM Antenna If you cannot achieve good reception with the supplied indoor FM antenna, try a commercially available out- door FM antenna instead. Notes: • Outdoor FM antennas work best outside, but usable results can sometimes be obtained when installed in an attic or loft.
Connecting Your Components About AV Connections • Before making any AV connections, read the manuals supplied with your other AV components. • Don’t connect the power cord until you’ve completed and double-checked all AV connections. Optical Digital Jacks The AV receiver’s optical digital jacks have shutter-type covers that open when an optical plug is inserted and close when it’s removed.

Connecting Your Components—Continued Hooking Up the Multichannel DVD Input If your DVD player supports multichannel audio formats such as DVD-Audio or SACD, and it has a multichannel analog audio output, you can connect it to the AV receiver’s multichannel DVD input. Use a multichannel analog audio cable, or several normal audio cables, to connect the AV receiver’s DVD IN FRONT L/R, CENTER, SURROUND L/R, and SUBWOOFER jacks to the 5.1-channel analog audio output on your DVD player.
Connecting Your Components—Continued Connecting Components with HDMI If you have an HDMI-compatible player, you can connect it to the AV receiver with an HDMI cable. Step 1: Connect your HDMI-compatible TV to the AV receiver’s HDMI OUT jack. Step 2: Connect your HDMI-compatible player to the AV receiver’s HDMI IN 1 or 2 jack. Step 3: Connect your HDMI-compatible player to an analog and/or digital audio input on the AV receiver.
