02 Connecting your equipment CAUTION • Make sure that all speakers are securely installed. This not only improves sound quality, but also reduces the risk of damage or injury resulting from speakers being knocked over or falling in the event of external shocks such as earthquakes. B-Speaker terminals: 1 Twist exposed wire strands together. 2 Push open the tabs and insert exposed wire. 3 Release the tabs. 1 2 3 Connecting the speakers The receiver will work with just two stereo speakers (the front speakers in the diagram) but using at least three speakers is recommended, and a complete setup is best for surround sound. Make sure you connect the speaker on the right to the right (R) terminal and the speaker on the left to the left (L) terminal. Also make sure the positive and negative (+/-) terminals on the receiver match those on the speakers. You can use speakers with a normal impedance between 6 Ω and 16 Ω. Be sure to complete all connections before connecting this unit to the AC power source. Bare wire connections A-Speaker terminals: 1 Twist exposed wire strands together. 2 Loosen terminal and insert exposed wire. 3 Tighten terminal. 1 2 3 10 mm (3/8 in.) CAUTION • These speaker terminals carry HAZARDOUS LIVE voltage. To prevent the risk of electric shock when connecting or disconnecting the speaker cables, disconnect the power cord before touching any uninsulated parts. • Make sure that all the bare speaker wire is twisted together and inserted fully into the speaker terminal. If any of the bare speaker wire touches the back panel it may cause the power to cut off as a safety measure. 10 mm (3/8 in.) Switching the speaker terminal If you selected Surr.Back in The Speaker System setting on page 41, you can switch between speakers using the SPEAKERS button. If you selected Height, the button will simply switch your main speaker terminal on or off. The options below are for the Surr.Back setting only.  Use the SPEAKERS button on the front panel to select a speaker terminal setting. SPEAKERS CONTROL - MULTI-ZONE - ON/OFF Press repeatedly to choose a speaker terminal option: • SPA - Sound is output from the speakers connected to the A-speaker terminals (multichannel playback is possible). • SPB - Sound is output from the two speakers connected to the B-speaker terminals (only stereo playback is possible). • SPAB - Sound is output from the A-speaker terminals, the two speakers in the B-speaker terminals, and the subwoofer. Multichannel sources are downmixed only when the STEREO or STEREO ALC mode is selected for stereo output from A- and B-speaker terminals. • SP - No sound is output from the speakers. Note • The subwoofer output depends on the settings you made in Speaker Setting on page 38. However, if SPB is selected above, no sound is heard from the subwoofer (the LFE channel is not downmixed). • All speaker terminals are switched off when headphones are connected. 12 En
