INSTALLATION AND CONNECTIONS 11Installation and ConnectionsSystem and Power ConnectionsThe HK 3380 is designed for flexible use withexternal control components and power ampli-fiers. These connections are easy to make duringan initial installation, or at a later date shouldyou choose to upgrade your system.Remote Control ExtensionIf the receiver is placed behind a solid or smokedglass cabinet door, the obstruction may preventthe remote sensor from receiving commands. Inthis event, an optional remote sensor may beused. Connect the output of the remote sensorto the Remote IR In jack .If other components are also prevented fromreceiving remote commands, only one sensor isneeded. They may use this unit’s sensor or aremote eye by running a connection from theRemote IR Out jack to the Remote In jackon Harman Kardon or other compatible equip-ment.External Audio Power AmplifierConnectionsIf desired, an optional, external amplifier may beused in place of the HK 3380’s internal poweramplifier.To connect an external power amplifier, firstremove the Pre-Out/Main-In Jumper Pinsthat connect the Preamp Out and Main In jacks on the rear panel. Keep the jumpers ina safe place should they be needed at a latertime.Using high-quality audio interconnect cables,connect the Preamp Out jacks to the inputjacks on your power amplifier. Make certain tomatch the right output to the right input and theleft output to the left input.Note that when an external power amplifier isused, no special adjustments are required. Allvolume and other control adjustments are madeusing the standard front panel or remote con-trols.AC Power ConnectionsThis unit is equipped with accessory AC outlets.They may be used to power accessory devices,but it should not be used with high-current drawequipment such as power amplifiers. The totalpower draw may not exceed 100W at these out-lets.The Switched AC Outlets will receivepower only when the unit is on. This is recom-mended for devices that have no power switch,or those with a mechanical power switch thatmay be left in the “ON” position.NOTE: Devices with electronic power switchesmay only go into a Standby mode when pluggedin here.Speaker PlacementFor optimal listening enjoyment, and for sound-field reproduction that best re-creates the origi-nal recording, it is good practice to place thespeakers so that they form a triangle with thespeakers at the front of the room, and the pre-ferred listening spot at the third point of the tri-angle. The distance between each speaker andthe listener should be identical.For example, if the speakers are 2,5 meters fromone another, each of the speakers should opti-mally be placed so that they are also 2,5 metersfrom the listener. It is also desirable to placespeakers so that their tweeters, or highfrequencydrivers, are aimed at ear height when you areseated in the listening position.A good starting point for speaker placement is to makethe distance between the two speakers and the distancebetween either speaker and the listener identical.To optimize the sound field, or to suit your lis-tening room environment, you may find thatsome experimentation is required to find thecorrect location. Ideally, pans from left to rightacross the front of the room should soundsmooth, and instruments should appear to becoming from the proper location within anorchestra.The placement of subwoofers should be done assuggested in the manufacturer’s instructions. Ingeneral, subwoofers often produce best resultswhen they are placed in the corner of a room,along the same wall as the speakers, but optimalplacement will vary widely depending on roomsize, the subwoofer type and the placement ofrugs and furniture in a room. It may be helpfulto temporarily position the subwoofer in theusual listening position, then walk around theroom while program material is playing until thebass reproduction sounds best to your ears. Thatlocation is likely to be the optimum position forthe subwoofer.Finally, when all connections are complete, plugthe power cord into a nonswitched 230-volt ACwall outlet.
