Connecting a Power Amplifier If you want to use a more powerful power amplifier, you can use the AV receiver as a preamp. Connect all speaker outputs to the power amplifier. See the manuals supplied with your amplifier for details. *1 L *2 R Power amplifier SB···Surround Back, FH···Front High, FW···Front Wide Note *1 Specify "None" for any channel that you don't want to output (➔ page 60). *2 When connecting to the SB/FH/FW EXT AMP jacks, you must set the "Preout to External Amplifier" setting (➔ page 59). Using Speakers Without Crossover Network Important: • Speakers without crossover network are speakers with no built-in crossover network. • With speakers without crossover network, be careful NOT to connect tweeters and woofers the wrong way around, as this may damage your speakers. • With speakers without crossover network, be careful not to set "Speaker Type (Front)" to "Bi-Amp" as this may damage your speakers. Make sure that this setting is set to "Digital Crossover". • Confirm that your speakers are without crossover network by referring to your speaker manual. Connecting speakers without crossover network provide a fine, three-dimensional sound field that extends bass and treble performance to the fullest extent. When speakers without crossover network are used, the AV receiver is able to drive up to a 5.1 speaker system in the main room. You must enable "Digital Crossover" in "Speaker Type (Front)" (➔ page 59) and make the settings of "Digital Processing Crossover Network" (➔ page 63). Connections Note • You need to make the setting before connecting the speakers. Tweeter (high) Woofer (low) Front right Front left En-17
