System and Power Connections

Installation and Connections

The HK 3470 is designed for flexible use with external control components and power ampli- fiers. These connections are easy to make dur- ing an initial installation, or at a later date should you choose to upgrade your system.

Remote Control Extension

If the receiver is placed behind a solid or smoked glass cabinet door, the obstruction may prevent the remote sensor from receiving com- mands. In this event, an optional remote sensor may be used. Connect the output of the remote sensor to the Remote IR In jack ¢.

If other components are also prevented from receiving remote commands, only one sensor is needed. They may use this unit’s sensor or a remote eye by running a connection from the Remote IR Out jack ∞ to the Remote In jack on Harman Kardon or other compatible equip- ment.

External Audio Power Amplifier Connections

If desired, an optional, external amplifier may be used in place of the HK 3470’s internal power amplifier.

To connect an external power amplifier, first remove the Pre-Out/Main-In Jumper Pins

›that connect the Preamp Out ﬁ and Main In ‹ jacks on the rear panel. Keep the jumpers in a safe place should they be needed at a later time.

Using high-quality audio interconnect cables, connect the Preamp Out jacks ﬁ to the input jacks on your power amplifier. Make certain to match the right output to the right input and the left output to the left input.

Note that when an external power amplifier is used, no special adjustments are required. All volume and other control adjustments are made using the standard front panel or remote controls.

If you wish to use external processing equip- ment, such as an equalizer, you may connect the device to the preamp-out and main-in jacks by removing the Preamp-Out/Main-In Jumper Pins › and connecting the Preamp Out ﬁ jacks to the inputs of the external device, and the outputs of the device to the Main In ‹ jacks.

Alternatively, you may connect the external device to the Tape Monitor Loop. Connect the Tape Monitor Record/Out jacks ‚ to the inputs of the external device, and connect the outputs of the device to the Tape Monitor Play/In jacks ª.

AC Power Connections

The Accessory Outlets · receive power as long as the receiver is turned on. Power to these outlets is removed when the unit is in the Standby mode, or when the Main Power Switch 1 is in the “OFF” position.

Speaker Placement

For optimal listening enjoyment, and for sound- field reproduction that best re-creates the origi- nal recording, it is good practice to place the speakers so that they form a triangle with the speakers 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 and the listener should be identical.

For example, if the speakers are 10 feet from one another, each of the speakers should opti- mally be placed so that they are also 10 feet from the listener. It is also desirable to place speakers so that their tweeters, or high- frequency drivers, are aimed at ear height when you are seated in the listening position.

Left Front	Right Front
Speaker	Speaker

A good starting point for speaker placement is to make the distance between the two speakers and the distance between either speaker and the listener identical.

To optimize the sound field, or to suit your lis- tening room environment, you may find that some experimentation is required to find the correct location. Ideally, pans from left to right across the front of the room should sound smooth, and instruments should appear to be coming from the proper location within an orchestra.

The placement of subwoofers should be done as suggested in the manufacturer’s instructions. In general, subwoofers often produce best results when they are placed in the corner of a room, along the same wall as the speakers, but optimal placement will vary widely depending on room size, the subwoofer type and the placement of rugs and furniture in a room. It may be helpful to temporarily position the sub- woofer in the usual listening position, then walk around the room while program material is playing until the bass reproduction sounds best to your ears. That location is likely to be the optimum position for the subwoofer.

Finally, when all connections are complete, plug the power cord into a nonswitched 120-volt AC wall outlet. You’re ready to enjoy the HK 3470!
