Audio and Speaker Connections

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 ⑦.
   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 Play jacks ⑨ . Connect the Record/In jacks on the recorder to the Tape Monitor Rec. Out jacks ⑩ on the HK 3370. When the tape deck connected to these jacks is a threehead 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, MD or other line-level audio device to the Tape 2 Play jacks If a recorder is used, connect its Rec/In jacks to the matching Tape 2 Record outputs
4. The audio 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 8.

5. Connect the outputs of a turntable with a moving magnet cartridge to the Phono inputs ⑥. To insure that the phono playback is noise-free, connect the ground wire from the tone-arm to the Phono Ground terminal ③.

6. Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM screw terminals 1.

1. Connect an FM antenna to the FM Antenna connection ②. The FM antenna may be an external roof antenna, an inside powered or wire lead antenna or a connection from a cable 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.

2. 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 14 and connecting the Preamp Out 15 jacks to the inputs of the external device, and the outputs of the device to the Main In 13 jacks.

Alternatively, you may connect the external device to the Tape Monitor Loop. Connect the Tape Monitor Record/Out jacks 10 to the inputs of the external device, and connect the outputs of the device to the Tape Monitor Play/In jacks 9.

Speaker and Output Connections

Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with an area of min. 2mm^2

Cable with 1.5mm^2 may be used for short runs of less than 3 meters. We do not recommend that you use cables with an area of 0.8mm^2 or smaller due to the power loss and degradation in performance that will occur.

Questions about running cables inside walls should be referred to an installer or a licensed electrical contractor who is familiar with 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 3370 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 Speaker 1 left and right or Speaker 2 left and right speakers, even if the speakers are a different distance from the HK 3370.

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, assure that both speakers are connected with the same polarity, i.e. speaker wires or terminals with any marking should be connected to the red speaker terminals on the HK3370, the others to the black ones (see connections below).

Connect the speakers using the following steps:

1. Connect the main speakers to the Speaker 1 terminals ①
2. Connect a second set of speakers, or speakers that are in a second room location, to the Speaker 2 terminals 13.
3. When an optional, powered subwoofer (not the aktive Sub of a Sub/Sat-System) is used, connect the outputs of the left and right Subwoofer Out jacks 16 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. When a separate passive subwoofer is used, these connections will be made to the optional amplifier that powers the subwoofer. If a Sub/Sat system is used (aktive or passive), connect the Speaker 1 terminals 17 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.

System and Power Connections

The HK 3370 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 4.

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 ⑤ 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 3370's internal power amplifier.

To connect an external power amplifier, first remove the Pre-Out/Main-In Jumper Pins 14 that connect the Preamp Out 15 and Main In 13 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 ⑤ 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

This unit is equipped with an accessory AC outlet. It may be used to power accessory devices, but it should not be used with high-current draw equipment such as power amplifiers. The total power draw may not exceed 100W at this outlet.

This Switched AC Outlet will receive power only when the unit is on. This is recommended for devices that have no power switch, or those with a mechanical power switch that may be left in the "ON" position.

NOTE: Devices with electronic power switches may only go into a Standby mode when plugged in here.

Power to this outlet 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 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 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 subwoofoers should be done as suggested in the manufacturer's instructions. In general, subwoofoers 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 230-volt AC wall outlet. You're ready to enjoy the HK 3370!

Basic Operation

The HK 3370 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 3370 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 A 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 8 9 11 13 14 17 or remote C.

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 3 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. Power to any equipment plugged into the rear panel Switched AC Outlet 9 will be shut off.

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.

Note that due its EEPROM backup system the HK3370 will retain information such as programmed presets for a virtually infinite time (see "Memory Backup", page 14).

• To dim the brightness of the front panel display, press the Dimmer button H on the remote or on the front panel 16.

The first press will dim the lights to half normal. A second press will turn the display completely off. Press the Dimmer button H16 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 or front panel 8911131417.

• During a listening session you may wish to adjust the Bass 20, Treble 21 and Balance 22 controls to suit your listening tastes.

• Adjust the volume to a comfortable level using the front panel Volume Control 23 or remote Master Volume Up/Down P buttons. The volume level is displayed by the position of the Volume Indicator 24. Think of the Volume Control knob 23 as the face of a clock, with the Volume Indicator 24 indicating the hour. The HK 3370 is playing at the minimum volume level when the Volume Indicator 24 points to 7 o'clock; when the Volume Indicator 24 points to 5 PM, the HK 3370 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 R5. This will cut the output to all Pre and Sub Outs and 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 25 and the Volume/Mute indicator 24 will flash. Press the Mute button R5 again to return to normal operation.

• For private listening, plug the 6,3 mm 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 3370. To listen to one of the speaker sets, press the Speaker button 6 or 7 on the front panel corresponding to the desired speakers or press them both to listen to both speakers pairs. The active speakers will be indicated by a lit green LED in the Speaker Indicators 26 display. Both sets of speakers may be turned off for private headphone listening.

IMPORTANT NOTE: When two speaker pairs are connected to the HK 3370RDS and are to be used simultaneously, the impedance of each speaker must not be lower than 8 Ohms.

• To program the HK 3370 for automatic turnoff, press the Sleep button on the front panel or remote G. 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 25 and it will count down until the time has elapsed.

When the programmed time has elapsed, the unit will automatically turn off (to Standby mode). 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 or simply hold it pressed for some seconds 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.

Tuner Operation

The HK 3370's tuner is capable of tuning AM, FM and FM Stereo broadcast stations. Stations may be tuned manually or automatically, or they may be stored as favorite station presets and recalled from a 30-position memory.

Station Selection

1. Press the AM/FM 17 buttons on the front panel or on the remote to select the tuner as an input.

2. Press these buttons again at any time to switch between AM and FM.

3. To automatically search for the next higher- or lower-frequency station that has an acceptable signal hold the Tuning or button 10 on the front or 0 or 7 on the remote pressed and release it as soon as the tuner starts the frequency search. To tune to the next station, press the button again. Tap the Tuning button to advance one frequency increment at a time, or press and hold it to locate a specific station. When the TUNED indicator lights, the station is properly tuned and should be heard with clarity.

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 stereo station is weak, audio quality will be increased by switching to Mono mode by pressing the FM Mode button 18 S until the STEREO indicator goes out.

Preset Tuning

Up to 30 stations may be stored in the HK 3370'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 ⑨ 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.

For all preset numbers above "3" the station will be stored directly. Note that for the presets 1, 2 or 3 either you press the corresponding number and wait for 5 seconds or you press a "0" before you press the 1, 2 or 3, then the station will be stored at once.
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 3370's preset memories, first select the FM band. Next, press and hold the Auto Preset button until the MEMO and PRESET indicators begin to flash, hold on until 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 3370 will automatically assign a preset number to each station, and then search for the next station.

If the FM tuner find fewer than 30 FM stations with acceptable signal strength, the Auto Preset tuning will scan up to two more cycles until the remaining vacant preset memory spaces have been filled.

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 or the Auto Preset button is pressed again.

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 the same station on the same frequency (if more than one scan is made) or on more than one frequency. 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 15 on the front panel or remote.
• To automatically scan through the stations entered in the preset memory, press the Preset Scan button on 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 3370's tuner memory, first tune to the station using the Preset buttons on 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 . 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 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.

RDS Operation

RDS (Radio Data System) transmits station call signs or network information, station program type, text messages about the station or specifics of a musical selection and the correct time.

RDS Tuning

When an FM station is tuned in and it contains RDS data, the HK 3370 RDS will automatically display the station's call sign, with some private stations also other informations changing all 2 to 5 seconds, and the RDS indicator will light in the Information Display as well as indicators for the RDS services program type PTY (see below) and traffic announcement TA (see page 14) if transmitted by the station. As soon as a radiotext message is received completely the radiotext indicator RT will turn on too.

RDS Display Options

When an RDS station is tuned, press RDS Display button on the remote or FM 17 on the front panel to cycle through the RDS displays in the following order:

• The Station name (or other Program information with some private stations).
• The station's frequency.
  The Program Type (PTY) as shown in the following list in this manual.
• A "text" message (RT) containing special information from the broadcast station. Note that this message will scroll across the display to permit messages longer than the eight positions in the display. Depending on signal quality it may take up to 30 seconds for the text message to appear, in the meantime the word TEXT will flash in the display when RT is selected.
• The current time of day (CT) as transmitted by the station. It may take up to two minutes for the time to appear, in the meantime the word TIME will flash in the display when CT is selected. Note that the accuracy of the time message is set by the radio station, not the HK 3370 RDS.
• Some RDS stations may not choose to include some of these additional features. If the data required for the selected mode is not being transmitted, the Information Display will show a NOPTY, NOTEXT or NOTIME message after the individual time out.
• In any FM mode the RDS function requires a strong enough signal for proper operation. If you receive a partial message or see any RDS indicator going on and off, try slowly adjusting the antenna to improve the signal strength or tune to another, stronger, RDS station.

Program Search (PTY)

A major benefit of RDS is its ability to encode broadcasts with Program Type (PTY) codes that indicate the type of material being broadcast. The following list shows the abbreviations used to indicate each PTY along with an explanation of the PTY:

• RDS ONLY: (see item 3 below)
• TRAFFIC: Traffic Information and Road Conditions (see Note below)
• P O P M: Popular Music
• ROCKM: Rock Music
  M. O. R M: Middle-of-the-Road Music
• LIGHTM: Classical Music
• CLASSICS: Serious Classical Music

You may search for a specific Program Type (PTY) by following these steps:

1. Press the RDS PTY button and note that the Information Display will show SELECT PTY.
2. After three seconds, the display will show the PTY that was selected for the last PTY search. If you wish to use the same PTY, press the RDS PTY button again within six seconds, and the tuner will begin to search for the first station with the appropriate PTY and acceptable signal strength.
3. To search for a different PTY, press the Tuning Up/Down buttons 17 10 while the last PTY selected is still displayed to scroll through the list of available PTY types. To search for the next available station with any RDS data, select RD S ONLY as the PTY type.
4. When the PTY is selected, press the RDS PTY button within six seconds, and note the PTY indicator will flash in the Information Display. The HK 3370 RDS will go into an automatic search mode and attempt to find the next station with

acceptable signal strength that matches the desired PTY type. Press the RDS PTY button twice again to find another matching station. When a station is tuned, the search will stop, a message R D S will blink in the Information Display and then the Display will show the station's "Call Letters" or other "Program Service" information.

1. While the PTY Indicator flashes in the display the tuner will make one complete scan of the entire FM band for the text station that matches the desired PTY type and has acceptable reception quality. If no such station is found, the word NONE will appear briefly in the Information Display, and the tuner will return to the last FM station in use before the search. To turn off the PTY Search at any time, press the RDS PTY button again.

NOTE: Many stations do not transmit a specific PTY. The display will show NONE, when such a station is selected and PTY is active.

NOTE: Some stations transmit constant traffic information. To identify as traffic station, they transmit a specific traffic code constantly, which causes the TA Indicator to light in the display. These stations can be found by selecting TRAFFIC, the second option in the PTY list. The HK 3370 will find the appropriate station, even if it is not broadcasting traffic information when the search is made.

Tape Recording

In normal operation, the audio source selected for listening through the HK 3370 is sent to the Tape Mon Rec Out ⑩ and Tape 2 Rec Out ② outputs. This means that any program you are listening to may be recorded simply by placing machines connected to the outputs for Tape Monitor ⑩ or Tape 2 ⑫ in the record mode. Moreover the source connected to Tape 2 Play ① may be recorded to a recorder connected to Tape Mon 9⑩ , rather than turned around.

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 9. Note that the T-Mon Indicator will light in the Main Information Display 25 to remind you that you are listening to the record playback instead of the actual input source being recorded.

As long as Tape Monitor 9 is selected the previously selected input source remains routed to the Record Outputs 10. Press the Tape Monitor Input Selector 9 again to turn the monitoring off and listen to the actual input source. Note that changing the Bass, Treble or Balance control will not affect the recordings, only the preamp and speaker outputs.

Memory Backup

This product is equipped with a memory backup system that preserves tunes preset if the unit is accidentally unplugged, turned off completely with the Main Power switch 1 or subjected to a power outage.

The unit's memory is stored in an EEPROM, and thus the HK 3370 will retain information such as programmed presets for a virtually infinite time without being connected to a main power source.

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.

To reset the system, first turn the HK 3370 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 913 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, you can release the buttons pressed now, the unit will return to Standby mode.

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.

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 , which also changes the input source selection on the HK 3370.

Source Selectors need not to be pressed with each function, but only when you intend to skip to another device to be controlled.

Three of the device pages are factoryprogrammed to operate compatibleHarman Kardon products. The Tape Monitordevice 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. Please refer to the table below for specific information on the default functions of the affected keys for these devices.
