12 INST ALLATION AND CONNECTIONS

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 so high that the signal is distorted.

2. Connect the Play/Out jacks of a cassette deck, CDR, MD or other audio recorder to the Tape Monitor In jacks ª. Connect the Record/In jacks on the recorder to the Tape Monitor Out jacks ‚ on the HK 3470.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, CDR,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 Tape 2 Record 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 noisefree,connect the ground wire from the tonearm 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 Antenna 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-to-75-ohm adapter supplied with the unit to make the connection.

To ensure 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 the receiver, the type of speakers you use,personal preferences and other factors.Your dealer or installer is a valuable resource for help 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 AWG14 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.

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 terminals on the HK 3470 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 Speaker1 left and right or Speaker2 left and right speakers, even if the speakers are a different distance from the HK 3470.

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:

Connect the main speakers to the Speaker 1

terminals ‡.

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 left and right Subwoofer Out jacks ﬂ 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 output jack for the connection. If the subwoofer has only speaker-level inputs and outputs,connect the

Speaker 1

terminals ‡ to the speaker-level inputs on the subwoofer, and then connect the speaker-level outputs on the subwoofer to your main left and right speakers,following the instructions provided with the subwoofer.When a passive subwoofer is used, these connections will be made to the optional amplifier that powers the subwoofer.

Installation and Connections

13 INST ALLATION AND CONNECTIONS

Installation and Connections

System and Power Connections

The HK 3470 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 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 equipment.

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 equipment, 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 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 10 feet from one another, each of the speakers should optimally be placed so that they are also 10 feet from the listener. It is also desirable to place speakers so that their tweeters,or highfrequency drivers,are aimed at ear height when you are seated in the listening position.

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 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 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 subwoofer 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 12 0-volt AC wall outlet.You’re ready to enjoy the HK 3470!

14 OPERATION

Basic Operation

The HK 3470 is simple to operate, and very similar to stereo receivers you may have used in the past. This section will explain the use of several features that may be new to you.

• Install the two supplied AAA batteries in the remote as shown. Be certain to observe the (+) and (–) polarity indicators shown in the bottom of the battery compartment.

• When using the HK 3470 for the first time,it will be necessary to press the Main Power button 1 on the front panel to turn the unit on.This places the unit in a standby mode,as indicated by the amber color of the Power Indicator 3 . Once the unit is in standby, you may begin a listening session by pressing the System Power Control 2 on the front panel or the Main Power On button å on the remote.Note that the Power Indicator 3 will turn red, then green.This will turn the unit on and return it to the input source that was last used.The unit may also be turned on from standby by pressing any of the Source

Selector buttons on the front panel 89 !#$&or remote ç.

To turn the unit off at the end of a listening session simply press the System Power

Control 2 on the front panel or the Main Power Off button ∫ on the remote.This

places the unit in the Standby mode,and the Power Indicator 3 will turn amber to remind you that the unit is ready for operation when a power command is received from the remote.

When the remote is used to turn the unit “off”, it is actually placing the system in a standby mode,as indicated by the amber color of the Power Indicator 3.

When you will be away from home for an extended period of time it is always a good idea to completely turn the unit off using the front panel Main Power Switch 1.

• To dim the brightness of the front panel display,press the Dimmer button ˙ on the remote.The first press will dim the lights to half normal.A second press will turn the display completely off.Press the Dimmer button ˙ again to restore the display to normal brightness.

Source Selection

• To select a source at any time, press any of the Source Selector buttons on the remote ç or front panel 89!#$&.

• During a listening session you may wish to adjust the Bass Ó, Treble Ô and Balance  controls to suit your listening tastes.

• Adjust the volume to a comfortable level using the front panel Volume Control Ò or remote Master Volume Up/Down π buttons.The volume level is displayed by the position of the Volume Indicator Ú.Think of the Volume Control knob Ò as the face of a clock, with the Volume Indicator Ú indicat- ing the hour.The HK 3470 is playing at the minimum volume level when the Volume

Indicator Ú points to 7 o ’clock; when the Volume Indicator Ú points to 12 o’clock

(straight up),the HK 3470 is playing at the maximum volume level. It is important that you make sure never to exceed this maximum volume level at any time,in order to avoid possible damage to your loudspeakers due to “clipping”, a type of distortion that is not audible to the human ear until it is severe enough to permanently damage most loudspeakers.It is also possible,depending upon the program material, for clipping to occur at volumes below the maximum volume level.

• To temporarily silence all speaker outputs, press the Mute button ®5.This will cut the output to all speakers,but it will not affect any recording or dubbing that may be in progress. When the system is muted, the MUTE indicator will light in the Main Information Display Û and the Volume/Mute indicator Ú will flash. Press the Mute button ®5 again to return to normal operation.

• For private listening,plug the 1/4" stereo phone plug from a pair of stereo headphones into the front panel Headphone jack 4.

• One or two separate sets of speakers may be connected to the HK 3470.To listen to one of the speaker sets,press the Speaker buttons 67 on the front panel corresponding to the desired speakers.The active speakers will be

indicated by a lit green LED in the Speaker Indicators Ù display.Both sets of speakers may be turned off for private headphone listening.

• To program the HK 3470 for automatic turnoff,press the Sleep button on the front panel ( or remote ©. Each press of the button will increase the time before shutdown in the following sequence:

The sleep time will be displayed in the Main Information Display Û and it will count down until the time has elapsed.

When the programmed time has elapsed,the unit will automatically turn off.Note that the front panel display will dim to one-half brightness when the Sleep function is programmed. To cancel the Sleep function,press the Sleep button (© until the Sleep indicator numbers disappear and the Main Information Display shows the current source.Pressing any control button while the Sleep control is activated will momentarily return the Main Information Display to full brightness for increased legibility without interrupting the Sleep function.

To take advantage of Harman Kardon’s exclusive VMAx mode, Press the VMAx button ^†.When the VMAx circuits are engaged, patented processing algorithms are used to create a three-dimensional sound space with the illusion of “phantom”speakers at center and surround positions.This spacious sound will simulate a surround-sound presentation without the need to add additional speakers.To return to standard stereo listening, press the

VMAx button ^† again and note that the VMAx Mode Indicator A will go out.

Tuner Operation

The HK 3470’s tuner is capable of tuning AM, FM and FM Stereo broadcast stations.Stations may be tuned manually,or they may be stored as favorite station presets and recalled from a 30-position memory.

4.Stations may also be tuned directly by pressing the Direct button ∆, and then pressing the Numeric Keys ˚ that correspond to the station’s frequency.The desired station will automatically be tuned.

NOTE:When the FM reception of a station is weak, audio quality will be increased by switching to Mono mode by pressing the FM Mode button *ßuntil the STEREO indicator goes out.

Preset T uning

Up to 30 stations may be stored in the HK 3470’s memory for easy recall using the front panel controls or the remote.In order to program preset stations into memory,you must use the remote control.

To enter a station into the memory, first tune the station using the steps outlined above. Then:

1.Press the Memory button ø on the remote.Note that the MEMO and PRESET indicators will light and flash in the Main Information Display.

2.Within five seconds, press the Numeric Keys ˚ corresponding to the location where you wish to store this station’s frequency.

3.Repeat the process after tuning any additional stations to be preset.

Auto Preset

• Preset stations may also be programmed automatically for the entire FM band.To automatically enter each station that may be tuned with acceptable quality into the HK 3470’s preset memories,first select the FM band. Next, press and briefly hold the Auto Preset button ¬ until the MEMO and PRESET indicators begin to flash, and the station frequency indication begins to increase.Release the button and note that the tuner will search the entire FM band, and stop briefly at each station that has acceptable signal strength.The HK 3470 will automatically assign a preset number to each

station, and then search for the next station. The automatic scan process will stop when all 30 preset memory locations have been filled or the entire FM band has been scanned three times.

NOTE:Using the automatic tuning mode in areas with more than 30 FM stations will completely fill the preset memories,and overwrite any previously memorized presets for either AM or FM stations.

TIP:The automatic scan process may enter stations that you do not wish to retain in the memory,or it may enter a station on more than one frequency if the signal is too strong.These unwanted stations may be removed from the memory using the Preset Clear function outlined below.

Recalling Preset Stations

• To manually select a station previously entered in the preset memory,press the Numeric Keys ˚ that correspond to the desired station’s memory location.

• To manually tune through the list of stored preset stations one by one

, press the Preset

buttons %∂on the front panel or remote.

• To automatically scan through the stations entered in the preset memory,press the Preset Scan button @œon the front panel or remote.The tuner will cycle through the list of preset stations,stopping for five seconds at each one.Press the button again to stop the scan at your desired station.

Clearing Preset Stations

Unwanted preset stations may be erased from the unit’s memory to make it easier to tune only those stations you want.

To remove a preset station from the HK 3470’s tuner memory,first tune to the station using the Preset Scan button @œon the front panel or remote,or by entering the preset number directly,using the Numeric Keys ˚.

When the preset station to be removed has been tuned, first press the Memory button ø. The MEMO and PRESET indicators in the Main Information Display will flash, and the actual preset number will disappear from the display. Next, press the Clear button Ñ within five seconds.

The preset station will be removed from the memory,and the action will be confirmed by the brief appearance of the word CLEAR and

the preset number location in the Main Information Display.That memory location will now be empty,and you may program a different station to that location, or leave it empty.

Tape Recording

In normal operation,the audio source selected for listening through the HK 3470 is sent to the Tape Mon Out and Tape 2 Rec Out outputs. This means that any program you are listening to may be recorded simply by placing machines connected to the outputs for Tape Monitor ‚ or Tape 2 ¤ in the record mode.

When a tape recorder with separate record and playback heads is used, you may monitor the output of the recording by selecting the Tape Monitor Input Selector 9ç. Note that the T-Mon Indicator will light in the Main Information Display Û to remind you that you are listening to the record playback instead of the actual input source being recorded.

IMPORTANT NOTE:Please make certain that you are aware of the copyright restrictions on any material you copy.

Operation

Using the Remote Control

It is convenient to think of the functions of the remote control buttons in terms of “pages”, where each source device (e.g.,CD player) represents its own page of remote functions. The result is that some of the keys will perform different functions depending upon which device page has been selected prior to pressing the key. Device pages are selected by pressing the

Source Selectors ç, which also changes the input source selection on the HK 3470.

Three of the device pages are factoryprogrammed to operate compatible Harman Kardon products.The Tape Monitor device page is programmed as a factory default to operate Harman Kardon cassette decks.The Tape 2 page defaults to Harman Kardon CD-R control codes.The CD page defaults to

Harman Kardon CD player or changer control codes.Note that all of these keys may be programmed in the learning mode to transmit different remote codes to perform other functions and/or operate other devices. Please refer to the table below for specific information on the default functions of the affected keys for these devices.

for five seconds,and then blink three times to indicate that it has reset all of the keys on the remote.The entire remote will now operate the factory default set of codes.

19 OPERATION/TROUBLESHOOTING

Operation

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 subjected to a power outage.The unit’s memory is stored in an EEPROM, and thus the HK 3470 will retain information such as programmed presets without being connected to a main power source virtually indefinitely.

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 HK 3470 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 at the top of the switch.

Next, press and hold the T-Mon and CD Input Selector buttons 9#on the front panel ONLY.While holding these buttons in, press the Main Power Switch 1 in until it latches, so that the button is flush with the front panel.

The Main Information Display will briefly show the word RESET,and then return to normal operation.

Note that when the system is reset in this fashion, all tuner presets will be lost and must be reentered.

If the system is still operating incorrectly,there may have been an electronic discharge or severe AC line interference that has corrupted the memory or microprocessor.

If these steps do not solve the problem, consult your dealer or an authorized Harman Kardon service center.
