About Home Theater Enjoying Home Theater You can use two sets of speakers with the TX-LR552: speaker set A and speaker set B. Speaker set A should be installed in your main listening room and can be used with Dolby Digital and DTS surround material. Each speaker must be positioned at a specific location in your listening room to get the best from surround sound material. The following illustration shows the best positions for your surround-sound speakers.
Connecting Speakers Connecting Speakers Before you connect your speakers, read the following: • Disconnect the power cord from the wall outlet. • Read the instructions supplied with your speakers. • Pay close attention to speaker wiring polarity. In other words, connect positive (+) terminals only to positive (+) terminals, and negative (–) terminals only to negative (–) terminals. If you get them the wrong way around, the sound will be out of phase and will sound odd.
Connecting Antenna Connecting Antenna This chapter 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 TX-LR552 won’t pick up any radio signals without any antenna connected, so you must connect the antenna to use the tuner. Connecting the Indoor FM Antenna The supplied indoor FM antenna is for indoor use only. 1 Attach the FM antenna, as shown. ■ American Model FM 75 Insert the plug fully into the socket.
Connecting Antenna—Continued 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. 2 Connect both wires of the AM loop antenna to the AM push terminals, as shown. Make sure that the wires are attached securely and that the push terminals are gripping the bare wires, not the insulation.
Connecting AV Components RCA AV Connection Color Coding Before Making Any Connections RCA-type AV connections are usually color coded: red, white, and yellow. Use red plugs to connect right-channel audio inputs and outputs (typically labeled “R”). Use white plugs to connect left-channel audio inputs and outputs (typically labeled “L”). And use yellow plugs to connect composite video inputs and outputs. • Read the manuals supplied with your AV components.
Connecting AV Components—Continued Connecting Both Audio & Video By connecting the audio and video outputs of your DVD player and other video components to the TX-LR552, you can select both the audio and video source simultaneously simply by selecting the appropriate input source on the TX-LR552. : Signal Flow TX-LR552 Video Video Audio Audio TV DVD player, etc.
Connecting AV Components—Continued Connecting Your TV or Projector Monitor Out Audio Connections ■ Using Composite Video Use a composite video cable to connect the TX-LR552’s V MONITOR OUT to a composite video input on your TV, as shown. These connections will allow you to listen to audio from your TV via the TX-LR552. If your TV has no audio outputs, connect the TX-LR552 to your VCR and use its tuner (see page 22). Note: • Initially, the OPT 1 digital input is assigned to the TV input source.
Connecting AV Components—Continued Connecting Your DVD player Video Connections Audio Connections You only need to use one of the following video connection methods. Note: • Initially, the COAX digital input is assigned to the DVD input source. If you connect your DVD player to a different digital input or only to an analog input, you’ll need to assign it to the DVD input source (see page 29).
Connecting AV Components—Continued DVD Multichannel Connection Connecting a VCR for Playback If your DVD player supports multichannel audio formats such as SACD and DVD-Audio, and it has a multichannel analog audio output, you can enjoy those formats. Use a multichannel analog audio cable to connect the TX-LR552’s DVD MULTI CH IN FR, FL, SL, SR, C, and SW sockets to the multichannel analog audio output on your DVD player, as shown. Alternatively, use three standard analog audio cables.
Connecting AV Components—Continued Audio Connections Connecting a D-VHS VCR for Playback • Use an analog audio cable to connect the TX-LR552’s AUDIO VIDEO 1 L/R OUTs to the audio inputs on your recording VCR. Video Connections Use a component video cable to connect the TX-LR552’s COMPONENT VIDEO 2 IN to the component video output on your D-VHS VCR, as shown. Your TV must also be connected via component video. A component video connection provides better picture quality than an S-Video connection.
Connecting AV Components—Continued Connecting Other Video Sources— Set-top Box (Satellite, Cable, Overthe-Air), LD Player, etc. Video Connections ■ Using Component Video Use a component video cable to connect the TX-LR552’s COMPONENT VIDEO INPUT 2 to the component video output on your video component, as shown. • Your TV must also be connected via component video. You only need to use one of the following video connection methods.
Connecting AV Components—Continued ■ Using Analog Connections If your video component doesn’t have digital audio outputs, or you want to record from it, you’ll need to make the following analog audio connections. Use an analog audio cable to connect the TX-LR552’s AUDIO VIDEO 2 IN L/R inputs to the analog audio outputs on your video component, as shown.
Connecting AV Components—Continued ■ Using a Coaxial or Optical Connection for Playback from Your Digital Recorder • Use an optical digital audio cable to connect the TX-LR552’s OPT 2 DIGITAL INPUT to the optical output on your recorder, as shown. OR • Use a coaxial digital audio cable to connect the TX-LR552’s COAX DIGITAL INPUT to the coaxial output on your recorder, as shown.
Connecting AV Components—Continued Connecting an Onkyo DVD Player with To use , you must make an analog audio connection (RCA) between the TX-LR552 and the other component, even if they are connected digitally. With (Remote Interactive) you can control your -compatible Onkyo DVD player with the TX-LR552’s remote controller, and use the following special functions: Connecting the Power Cord Notes: • Before connecting the power cord, connect all of your speakers and AV components.

Troubleshooting If you have any trouble using your TX-LR552, look for a solution in this section. If you can’t resolve the issue yourself, contact your Onkyo dealer. Power Can’t turn on the TX-LR552? • Make sure that the power cord is properly plugged into the wall outlet. • Unplug the power cord from the wall outlet, wait five seconds or more, then plug the cable in again. The TX-LR552 turns off as soon as it’s turned on? • The amp protection circuit has been activated.
Troubleshooting—Continued There’s no sound with a certain signal format? • Check the input signal format setting. Depending on the input source, you can select Auto, Multich, Analog, DTS, or PCM (page 49). • Check the digital audio output setting on the source component. On some games consoles, such as those that play DVDs, the default setting is off. • With some DVD-Video discs, you need to select an audio output format from a menu.
Troubleshooting—Continued Can’t control other components? • If it’s an Onkyo DVD player, make sure that the cable and analog audio cable (RCA) are connected properly. Connecting only an cable won’t work (page 27). • Make sure you’ve selected the correct remote controller mode (pages 10, 12, and 11). Recording Memory backup The TX-LR552 uses a battery-less memory backup system in order to retain radio presets and other settings when it’s unplugged or in the case of a power failure.
