Connections ■ Connecting external amplifiers This unit has more than enough power for any home use. However, if you want to use external amplifiers, connect the external amplifiers to the PRE OUT jacks. Each PRE OUT jack outputs the same channel signals as the corresponding SPEAKERS terminals. y Use the external amplifiers in the following cases: - when you want to add more power to the speaker output - when you want to use another amplifier for your presence of sounds - when you want to enjoy the 11.2-channel surround sound in the main zone with activating the other zones (see page 133) Pre-amplifier mode If you want use the external amplifiers for the all channels in the main zone, set "PREAMP MODE" to "ON" in the advanced setup (see page 143). When "PREAMP MODE" is set to "ON", the power consumption is reduced. 12 3456 (FRONT) (SINGLE) L R FRONT SURROUND CENTER (REAR) SUBWOOFER SUR.
