Installation and Connections

14

System Installation

After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment. These steps need to be done only when the receiver is first installed, or when a change is made to the input source equipment.

Audio Equipment Connections

We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the quality of the signals.

When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them.

1. Connect the analog output of a CD player to the CD inputs ¶.

NOTE: When the CD player has both fixed and variable audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or high that the signal is distorted.

2. Connect the Play/Out jacks of a cassette deck, MD or other audio recorder to the Tape Monitor Injacks ª. Connect the Record/In jacks on the recorder to the Tape Monitor Outjacks ‚ on the HK3270. When the tape deck connected to these jacks is a three-head unit or has off-head playback, it will be possible to monitor the output of the source being recorded.

3. Connect the output of a second audio recorder, VCR or other line-level audio device to the Tape 2 Play/In jacks ⁄. If a recorder is used, connect its Rec/In jacks to the matching outputs ¤.

4. The output of any electronics product with a line-level output, such as a TV set, satellite receiver or DVD may be connected to the Aux jacks •.

5. Connect the outputs of a turntable with a moving magnet cartridge to the

Phono inputs §. To insure that the

phono playback is noise-free, connect the ground wire from the tone arm to the Phono Ground terminal £.

6. Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM screw terminals ¡.

7. Connect an FM antenna to the

FM (75 ohm) connection ™. The

FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable TV system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you must use the 300-ohm-to75-ohm adapter supplied with the unit to make the connection.

Speaker and Output Connections

To assure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available, and the choice of cable may be influenced by the distance between your speakers and this receiver, the type of speakers you use, personal preferences and other factors. Your dealer or installer is a valuable resource to consult in selecting the proper cable.

Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of 14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable.

Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur.

Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area.

Installation and Connections

15

When connecting wires to the speakers, be certain to observe proper polarity. Remember to connect the “negative” or “black” wire to the same terminal on the receiver and the speaker. Similarly, the “positive” or “red” wire should be connected to the like terminal on the HK3270 and speaker.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front left and front right or surround left and surround right speakers, even if the speakers are a different distance from the HK3270.

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To assure proper phase, and optimal performance, consult the identification plate on your speaker , or the speaker’s manual to verify polarity . If you do not know the polarity of your speaker , ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.

Connect the speakers using the following steps:

1. Connect the main speakers to the

Speaker 1 terminals ﬂ.

2. Connect a second set of speakers, or speakers that are in a second room location to the Speaker 2 terminals ‡.

3. When an optional, powered subwoofer is used, connect the outputs of the

Subwoofer Out jacks ﬁ to the line-

level inputs of the subwoofer. When the subwoofer’s amplifier has stereo inputs, run interconnects from both jacks. When the subwoofer has a mono input only, use the bottom jack for the connection. When a passive subwoofer is used, these connections will be made to the optional amplifier that powers the subwoofer.

System and Power Connections

The HK3270 is designed for flexible use with external control components and power amplifiers. These connections are easy to make during 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 commands. In this event, an optional remote sensor may be used. Connect the output of the remote sensor to the Remote Cont. 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 Cont.

Out jack ∞ to the Remote In jack on

Harman Kardon or other compatible equipment.

External Audio Power Amplifier Connections

If desired, an optional, external amplifier may be used in place of the HK3270’s internal power amplifier.

To connect an external power amplifier, first remove the jumper pins that connect the Preamp Out › 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

› 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.

AC Power Connections

The Accessory Outlets ° receive power as long as the Main Power

Switch 1 is in the “ON” position.

Power will still be supplied to these outlets even when the HK3270 is in the Standby mode.

In order to remove power to these outlets, the unit must be turned off by pressing the Main Power Switch 1 so that it is in the “OFF” position.

Speaker Placement

For optimal listening enjoyment, and for soundfield reproduction that best re-creates the original 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 preferred listening spot at the third point of the triangle. The distance between each speaker and the listener should be identical.

For example, if the speakers are 2.5 meters from one another, each of the speakers should optimally be placed so that they are also 2.5 meters 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

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 is identical.

Right Front

Speaker

To optimize the soundfield, or to suit your listening 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 to where they would be placed in 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, but optimal placement will vary widely depending on room size, the subwoofer type and the placement of rugs and furniture in a room.

Finally, when all connections are complete, plug the power cord into a nonswitched120-volt AC wall outlet. You’re ready to enjoy the HK3270!

Memory Backup

This product is equipped with a memory backup system that preserves tuner presets and system configuration information if the unit is accidentally unplugged or subject to a power outage.

Processor Reset

In the rare case where the unit’s operation or the displays seem abnormal, the cause may involve the erratic operation of the system’s memory or microprocessor.

To correct this problem, first unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and check the unit’s operation. If the system still malfunctions, a system reset may clear the problem.

If the system still does not respond, it may be necessary to perform a complete reset. To reset the system, first turn the HK3270 off by pressing the Main Power

Switch 1 and then releasing it so that

it extends out beyond the front panel and the word “OFF” is visible in red lettering at the top of the switch.
