CONNECTIONS ■ Connecting to an external amplifier If you want to increase the power output to the speakers, or want to use another amplifier, connect an external amplifier to the PRE OUT jacks as follows. Notes • When audio pin plugs are connected to the PRE OUT jacks for output to an external amplifier, it is not necessary to use the corresponding SPEAKERS terminals. Set the volume of the external amplifier connected to this unit to the maximum. • The signal output through the FRONT PRE OUT and CENTER PRE OUT jacks are affected by the TONE CONTROL settings. • If SPEAKERS A is turned off and Multi Zone: Speaker B is set to "Zone B" (see page 63), signals will only be output from the FRONT PRE OUT jacks. 1 2 3 4 R L FRONT R L SURROUND SUB WOOFER R CENTER L SURROUND BACK/PRESENCE PRE OUT 5 1 FRONT PRE OUT jacks Front channel line output jacks. 2 SURROUND PRE OUT jacks Surround channel line output jacks. 3 SUBWOOFER PRE OUT jack Connect a subwoofer with built-in amplifier, such as the YAMAHA Active Servo Processing Subwoofer System, to this jack. 4 SURROUND BACK/PRESENCE PRE OUT jacks Surround back or presence channel line output jacks. If you only connect one external amplifier for the surround back channel, connect it to the left (L) jack. 5 CENTER PRE OUT jack Center channel line output jack. Notes • Each PRE OUT jack outputs the same channel signal as the corresponding speaker terminals. However, when both surround back and presence speakers are setup in this unit, the signals output from SURROUND BACK/PRESENCE PRE OUT jacks may not correspond to the correct speakers. • Adjust the volume level of the subwoofer with the control on the subwoofer. • Some signals may not be output from the SUBWOOFER PRE OUT jack depending on the Speaker Set settings (see page 58). 22
