AVR80 manual 11/01/98 13:01 Side 12 Installation, Set Up & Configuration 12 ENGLISH External Audio Power Amplifier Connections Using the PRE OUT jacks ñ, connections may be made to external power amplifiers. To make these connections, remove the jumpers between PRE-OUT and MAIN IN, and save them for future use. Connect the PREOUT of the channels to be connected to external amplifiers to that amplifier's inputs. Volume will still be controlled by this receiver. When an external amplifier is used for the front channels, this receiver's rear channel outputs and one passive (nonpowered) subwoofer may be connected to this unit's internal amplifier for higher power output. To make these connections, follow the diagrams on this page. Using short RCA to RCA jumpers, connect the left and right SURR PREOUT jacks to the left and right FRONT MAIN IN jacks. A subwoofer may be connected by connecting the SUBWOOFER PRE OUT to the CENTER MAIN IN. If these connections are used, changes must be made to the speaker outputs. Connect the left and right surround speakers to the speaker terminals labeled FRONT ˙î and the passive subwoofer to the speaker terminals labeled CENTER ∆. NOTE: When external power amplifiers are used, the center channel speakers should receive at least as much amplifier power as the front left and right speakers. AC Power Connections This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high current draw equipment such as power amplifiers (not more than 50 Watts each). The SWITCHED † outlet will receive power only when the unit is on. This is recommended for devices that have no power switch, or a mechanical power switch that may be left in the "ON" position (as for example with the harman/kardon CDPlayer HD730). Devices with electronical power switch may only switch on to standby mode, if pluged in here. The UNSWITCHED ü outlet will receive power as long as the unit is plugged into a powered AC outlet. Finally, when all connections are complete, plug the power cord into a non-switched AC wall outlet. Note that the ring surrounding the Power Switch ( will turn amber.
