AVR146 harman/kardon

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and

semiconductor "chip" components.

The following techniques should be used to help reduce the incidence of component damage caused by static electricity.

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on

your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,

which should be removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge build-up or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges

sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacement

ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

CAUTION :

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together

or your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.

Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

Each precaution in this manual should be followed during servicing.

Components identified with the IEC symbol in the parts list are special significance to safety. When replacing a component identified with

, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in the

parts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptably

insulated from the supply circuit before retuming the product to the customer.

SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed o.5mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

CONNECTIONS

There are different types of audio and video connections used to connect the receiver to the speakers and video display, and to connect the source devices to the receiver.To make it easier to keep them all straight, the Consumer Electronics Association (CEA) has established a color-coding standard.Table 1 may be helpful to you as a reference while you set up your system.

Types of Connections

This section will briefly review different types of cables and connections that you may use to set up your system.

Speaker Connections

Speaker cables carry an amplified signal from the receiver’s speaker terminals to each loudspeaker. Speaker cables generally contain two wire conductors,or leads,inside plastic insulation. The two conductors are usually differentiated in some way, by using different colors,or stripes,or even by adding a ridge to the insulation. Sometimes the actual wires are different, one being copper-colored and the other silver.

The differentiation is important because each speaker must be connected to the receiver’s speaker-output terminals using two wires,one positive (+) and one negative (–).This is called speaker polarity.It’s important to maintain the proper polarity for all speakers in the system. If some speakers have their negative terminals connected to the receiver’s positive terminals,performance can suffer,especially for the low frequencies.

Always connect the positive terminal on the loudspeaker, which is usually colored red, to the positive terminal on the receiver, which is colored as shown in the Connection Color Guide (Table 1). Similarly,always connect the black negative terminal on the speaker to the black negative terminal on the receiver.

The AVR 146 uses binding-post speaker

Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

terminals that can accept banana plugs or bare-wire cables.

Banana plugs are simply plugged into the hole in the middle of the terminal cap. See Figure 1.

Bare wire cables are installed as follows (see Figure 2):

1. Unscrew the terminal cap until the pass-through hole in the collar is revealed.

2. Insert the bare end of the wire into the hole.

3. Screw the cap back into place until the wire is held snugly.

12 3

Figure 2 – Binding-Post Speaker Terminals With Bare Wires

Subwoofer

The subwoofer is a specialized type of loudspeaker that is usually connected in a different way. The subwoofer is used to play only the low frequencies (bass), which require much more power than the other speaker channels.In order to obtain the best results,most speaker manufacturers offer powered subwoofers,in which the speaker contains its own amplifier on board. Sometimes the subwoofer is connected to the receiver using the front left and right speaker outputs,and then the front left and right speakers are connected to terminals on the subwoofer. More often, a line-level (nonamplified) connection is made from the receiver’s Subwoofer Output to a corresponding jack on the subwoofer, as shown in Figure 3.

Although the subwoofer output looks similar to the analog audio jacks used for the various components,it is filtered and only allows the low frequencies to pass.Don’t connect this output to your other devices. Although doing so won’t cause any harm, performance will suffer.

Connecting Source Devices to the AVR

The AVR 146 is designed to process audio and video input signals, playing back the audio and displaying the video on a television or monitor connected to the AVR. These signals originate in what are known as “source devices,” including your DVD player, CD player, DVR (digital video recorder) or other recorder, tape deck, game console,cable or satellite television box or MP3 player.Although the tuner is built into the AVR,it also counts as a source, even though no external connections are needed, other than the FM and AM antennas.

Separate connections are required for the audio and video portions of the signal.The types of connections used depend upon what’s available on the source device,and for video signals,the capabilities of your video display.

Optical

AVR146 harman/kardon

CONNECTIONS

Audio Connections

There are two formats for audio connections: digital and analog.Digital audio signals are of higher quality, and are required for listening to sources encoded with digital surround modes,such as Dolby Digital and DTS.There are two types of digital audio connections:coaxial and optical. Either type of digital audio connection may be used for each source device,but never both simultaneously for the same source.However,it’s okay to make both analog and digital audio connections at the same time to the same source.

NOTE: Although HDMI cables are capable of carrying digital audio signals,the AVR 146 is not designed to process those signals.Therefore, if your source and video display are both HDMI-capable,use the HDMI connections for video only.Make a separate audio connection from the source device to the AVR 146,and turn the volume on your TV all the way off.

Digital Audio

Coaxial digital audio jacks are usually color-coded in orange.Although they look similar to analog jacks,they should not be confused, and you should not connect coaxial digital audio outputs to analog inputs or vice versa. See Figure 4.

Coaxial digital audio cable

Harman Kardon receivers also include a proprietary,dedicated audio connection called “The Bridge/DMP”. If you own an iPod with a dock connector, you may purchase The Bridge separately and connect it to The Bridge/DMP port on the receiver. See Figure 8. Dock your iPod (not included) in The Bridge, and you may play your audio and video materials through your high-performance system.You may even use the AVR 146 remote to control the iPod, with navigation messages displayed on the front panel and on the screen of a video display connected to the AVR.

Optical digital audio cable

Figure 5 – Optical Digital Audio

Due to the nature of digital signals as binary bits,they aren’t subject to signal degradation the way analog signals are.Therefore, the quality of coaxial and optical digital audio connections should be the same, although it is important to limit the length of the cable.Whichever type of connection you choose,Harman Kardon recommends that you always select the highest quality cables available within your budget.

Analog Audio

Analog connections require two cables,one for the left channel (white) and one for the right channel (red).These two cables are often attached to each other for most of their length. See Figure 6. Most sources that have digital audio jacks also have analog audio jacks,although some older types of sources,such as tape decks,have only analog jacks. For sources that are capable of both digital and analog audio,you may wish to make both connections.If you wish to record materials from DVDs or other copy-protected sources,you may only be able to do so using analog connections.Remember to comply with all copyright laws if you choose to make a copy for your own personal use.

Video Connections

Although some sources produce an audio signal only (e.g., CD player, tape deck), many sources output both audio and video signals (e.g., DVD player, cable television box, HDTV tuner, satellite box, VCR, DVR). In addition to the audio connection, you will need to connect one type of video connection for each of these sources (never more than one at the same time for any source).

Digital Video

The AVR 146 is equipped with two HDMI (High-Definition Multimedia Interface) inputs,and one output. HDMI is capable of carrying digital audio and video information using a single cable,thus delivering the highest possible quality picture and sound.

There are different versions of HDMI, depending on the capability of the source device and the type of signal it is capable of transmitting via the HDMI connection.

In addition, receivers and processors such as the AVR 146 may handle the incoming signal in several different ways,depending on their capability as well.The AVR 146 is only capable of switching the HDMI data.That is,the incoming audio and video data, including 1080i and 1080p video, will be passed directly to your HDMI-capable video display, without the

AVR146 harman/kardon

CONNECTIONS

AVR 146 processing any of the data.Although this enables the AVR 146 to be compatible with virtually any HDMI-capable source device and video display, it requires a separate audio connection for each source since the AVR 146 doesn’t have access to the audio data in the HDMI stream.

™

The AVR 146 has been tested and is Simplay HD

-verified, which guarantees compatibility via the HDMI connection with other products that also bear the Simplay HD logo.

The AVR 146 will not convert analog video signals to the HDMI format, and the on-screen displays are not visible when using an HDMI source. Therefore,you will need to connect the composite or S-video monitor output to your video display (or both, depending on which video connections your sources use) to view the on-screen menus.

The physical HDMI connection is simple.The connector is shaped for easy plug-in (see Figure 9). If your video display has a DVI input, you may use an HDMI-to-DVI adapter (not included) to connect it to the AVR’s HDMI Output.

Component video cable

Figure 12 – Component Video

If it’s available on your video display, HDMI is recommended as the best quality connection, followed by component video,S-video and then composite video.

NOTE: A composite or S-video connection to your TV is required to view the AVR’s on-screen displays.

Antennas

The AVR 146 uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner.

The FM antenna uses a 75-ohm F-connector. See Figure 13.

Figure 9 – HDMI Connection

Analog Video

There are three types of analog video connections: composite video, S-video and component video.

Composite video is the basic connection most commonly available. The jack is usually color-coded yellow,and looks like an analog audio jack, although it is important never to confuse the two.Do not plug a composite video cable into an analog or coaxial digital audio jack, or vice versa. Both the chrominance (color) and luminance (intensity) components of the video signal are transmitted using a single cable. See Figure 10.

Composite video cable

Figure 10 – Composite Video

S-video,or “separate” video, transmits the chrominance and luminance components using separate wires contained within a single cable.The plug on an S-video cable contains four metal pins,plus a plastic guide pin. Be careful to line up the plug correctly when you insert it into the jack on the receiver, source or video display.See Figure 11.

Figure 13 – FM Antenna

The AM loop antenna needs to be assembled.Then connect the two leads to the screw terminals on the receiver. See Figure 14.

Figure 14 – AMAntenna

S-video cable

Figure 11 – S-Video

Component video separates the video signal into three components – one luminance (“Y”) and two subsampled color signals (“Pb” and “Pr”) – that are transmitted using three separate cables.The “Y”cable is color-coded green, the “Pb”cable is colored blue and the “Pr” cable is colored red. See Figure 12.

INSTALLATION

You are now ready to connect your various components to your receiver. Before beginning,make sure that all components, including the AVR 146, are turned completely off and their power cords are unplugged. Don’t

plug any of the power cords back in until you have finished making all of your connections.

Remember that your receiver generates heat while it is on. Select a location that leaves several inches of space on all sides of the receiver. It is preferable to avoid completely enclosing the receiver inside an unventilated cabinet. It is also preferable to place components on separate shelves rather than stacking them directly on top of the receiver. Some surface finishes are delicate.Try to select a location with a sturdy surface finish.

Step One – Connect the Speakers

If you have not yet done so,place your speakers in the listening room as described in the Speaker Placement section above.

Connect the center, front left, front right, surround left and surround right loudspeakers to the corresponding speaker terminals on the AVR 146. See Figure 16. Remember to maintain the proper polarity by always connecting the positive and negative terminals on each speaker to the positive and negative terminals on the receiver. Use the Connection Color Guide on page 16 as a reference.

INSTALLATION

HDMI 1 Source

The HDMI 1 source is used with a device that is capable of outputting digital video through an HDMI connection, such as a DVD, HD-DVD or Blu-ray Disc player or HDTV tuner.The HDMI 1 source is not used with any of the 2-channel analog audio or video inputs on the AVR 146.

Since the AVR 146 is not capable of processing either the audio or video signal transmitted via the HDMI connection, you will need to connect the source’s coaxial digital audio output to the Coaxial 2 digital audio input on the AVR 146, or use the 6-channel inputs.See Figure 24. You will also need to make sure your video display is HDMI-capable,and for many source devices,the display must be HDCP-compliant (High-Bandwidth Digital Content Protection) in order to display copy-protected materials. The AVR 146 is Simplay HD-verified, for compatibility via the HDMI connection with other Simplay HD-verified products.

If your source or video display is equipped with a DVI (Digital Video Interface) input, you may use an HDMI-to-DVI adapter (not included).

Figure 24 – HDMI and Coaxial 2 Inputs

HDMI 2 Source

The HDMI 2 source is used with a second device that is capable of outputting digital video through an HDMI connection, such as a DVD, HD-DVD or Blu-ray Disc player.The HDMI 2 source is not used with any of the 2-channel analog audio or video inputs on the AVR 146.

Since the AVR 146 is not capable of processing either the audio or video signal transmitted via the HDMI connection, you will need to connect the source’s optical digital audio output to the Optical 2 digital audio input on the AVR 146, or use the 6-channel inputs.See Figure 25. You will also need to make sure your video display is HDMI-capable,and for many source devices,the display must be HDCP-compliant (High-Bandwidth Digital Content Protection) in order to display copy-protected materials.

If your source or video display is equipped with a DVI (Digital Video Interface) input, you may use an HDMI-to-DVI adapter (not included).

Step Five – Connect the Video Display

Only video connections should be made between the receiver and your video display (TV), unless your TV is the source for your television programming (see Video 2 Source, above).

You will need to make a video connection for each type of video used for your sources.In addition, even if you didn’t use S-video or composite video for any of your sources,one of these video monitor connections is required to view the AVR 146’s on-screen menus and displays.

The CD source is used for a strictly audio device,such as a CD player. Referring to Table 2,connect your CD player to the CD Analog Audio

inputs and to any available digital audio input. See Figure 26.

Figure 26 – CD Audio Inputs and Digital Audio Inputs

No video connections are needed.

First, determine what types of video your display is capable of handling. Remember that HDMI is preferred, followed by component video, S-video and then composite video.Ideally,this guided you in selecting the video connections for your sources.

Next, note which types of video connections you used for your source devices.Make sure you didn’t use a better type of video connection for a source than your video display can handle.If so,you will need to disconnect the source and use a video connection that’s compatible with your display.

AVR146 harman/kardon

INSTALLATION

If you used an HDMI video connection for any of your sources,then connect the HDMI Output on the AVR to an HDMI input on your video display. See Figure 29. As mentioned previously, you will need to make a separate digital audio connection from each source device to the AVR 146,and you will also need to consult the owner’s guide for your television to learn the proper procedure for disabling or muting the audio.

Figure 29 – HDMI Output

If you used component video for any sources,connect the Component Video Monitor outputs on the receiver to one set of component video inputs on your display. See Figure 30. Make a note of how these inputs are labeled on the display.

Figure 30 – Component Video Monitor Outputs

If you used S-video for any sources,or if all of your sources used HDMI or component video,connect the S-video Monitor output on the receiver to an S-video input on your display. See Figure 31. Make a note of how the input is labeled.

If you used composite video for any sources,connect the composite video Monitor output on the receiver to a composite video input on the display. See Figure 31. Again, make a note of how this input is labeled on the display.

Figure 31 – S-Video and Composite Video Monitor Outputs

Consult the manual for your TV to make sure you understand how to select each video input.As you play different source devices that use different types of video connections,select the correct video input on your video display.

Step Six – Plug in AC Power

Having made all of your wiring connections,it is now time to plug each component’s AC power cord into a working outlet.

Before plugging the AVR 146’s AC Power Cord into an electrical outlet, make sure that the Master Power Switch on the front panel is popped out so that the word OFF appears on its top.Gently press the button to turn the switch off.This will prevent the possibility of damaging the AVR in case of a transient power surge.

Insert the batteries as shown in Figure 32, making sure to observe the correct polarity.

Figure 32 – Remote Battery Compartment

When using the remote,remember to point the lens toward the front panel of the AVR 146. Make sure no objects,such as fur niture, are blocking the remote’s path to the receiver. Bright lights,fluorescent lights and plasma video displays may interfere with the remote’s functioning. The remote has a range of about 20 feet, depending on the lighting conditions.It may be used at an angle of up to 30 degrees to either side of the AVR.

If the remote seems to operate intermittently, or if pressing a button on the remote does not cause the AVR Selector or one of the Input Selectors to light up,then make sure the batteries have been inserted correctly, or replace all three batteries with fresh ones.

Step Eight – Program Sources Into the Remote

The AVR 146 remote not only is capable of controlling the receiver, but it may also be programmed to control many brands and models of VCRs,DVD players,CD players, cable boxes,satellite receivers,cassette decks and TVs, as well as an iPod docked in The Bridge.

It may help to think of the remote as a book with pages.Each page represents the button functions for a different device.In order to access the functions for a particular device,you first need to turn to that page, that is,switch the remote to that device mode. This is done by pressing the AVR Button to access the codes that control the receiver, or the Input Selector buttons to access the codes for the devices programmed into the remote.

You may have noticed that three of the Input Selectors look different from the others (see Figure 33). For the DVD/CD,TAPE/The Bridge and HDMI 1/HDMI 2 Selectors,there is a primary source, whose name is printed on the button, and a secondary source,whose name is printed in green above the button.To access the code set for the primary source (which also selects that source input on the AVR and turns on the AVR), press the Input Selector once.The Input Selector will light in red to indicate that the primary source is active.

Step Seven – Insert Batteries in Remote

The AVR 146 remote control uses three AAA batteries, which are included.

To remove the battery cover located on the back of the remote,fir mly press the ridged depression and slide the cover towards the top of the remote.

To access the code set for the secondary source (which also selects that source input on the AVR and turns on the AVR),press the Input Selector a second time.The Input Selector will light in green to indicate that the secondary source is active.

The AVR 146’s remote is factory-programmed to control an iPod docked in The Bridge and many Harman Kardon DVD and CD players. If you have other source devices in your system, follow these steps to program the correct codes into the remote.

2.Turn on your source device.

3.This step places the remote in program mode,and varies slightly, depending on which Input Selector is being programmed. Refer to Figure 33.

a) DVD,Tape,Video 1, Video 2 and Video 3 Sources: Press and

hold the Input Selector until the LED on the remote starts to flash, then release it. Follow the directions in Step 4,below.

b) CD Source: Press the DVD/CD Input Selector once and release it,

then quickly press and hold the Input Selector until it turns green, and the Program LED starts to flash, then release it. Follow the directions in Step 4, below.

c) HDMI 1 Source: Press and hold the Input Selector until it turns

red, and the Program LED starts to flash, then release it. Next, press the Input Selector that corresponds to the device type you want to program into the HDMI 1 mode,i.e.,DVD,VCR/PVR or CBL/SAT. Then follow the directions in Step 4, below.

d) HDMI 2 Source: Press and release the Input Selector once,then

quickly press the Input Selector again and hold it until it turns green, and the Program LED starts to flash, then release it. Next, press the Input Selector that corresponds to the device type you want to program into the HDMI 2 mode,i.e.,DVD,VCR/PVR or CBL/SAT. Then follow the directions in Step 4, below.

6.You may find out which code number you have programmed by pressing and holding the Input Selector to enter the Program mode. Then press the Set Button, and the Program Indicator LED will flash in the code sequence.One flash represents “1”, two flashes for “2”, and so forth.A series of many fast flashes represents “0”. Record the codes programmed for each device in Table 3.

Button repeatedly until the device turns off.When the device turns off, enter the code by pressing the Input Selector, which will flash. The remote then exits Program mode.

5. Once you have programmed a code,it’s a good idea to try using

some other functions to control the device.Sometimes manufacturers use the same Power code for several different models, while other codes will vary.You may wish to repeat this process until you’ve

Most of the button labels on the remote describe the button’s function when used to control the AVR 146. However,the button may perform a very different function when used to control another device.Refer to the Remote Control Function List,Table A8 in the Appendix, for each button’s functions with the various product types.

If you wish, you may program Macros,which are preprogrammed code sequences that execute many code commands with a single button press.You may also program “punch-through” codes, which allow the remote to operate the volume,channel or transport controls of another device without having to switch the remote’s device mode. See pages 45 through 46 for instructions on these advanced programming functions.

NOTE: The AVR 146 remote is preprogrammed to operate the transport controls of Harman Kardon DVD players when the AVR or the Video 2 (cable/satellite) or Video 3 (TV) source is selected. You may change this punch-through programming at any time.

Now that you have installed your system components and completed at least a basic configuration of your receiver, you are ready to begin enjoying your home theater system.

Turning On the AVR 146

Gently press the Master Power Switch until the word OFF is no longer visible.The Power Indicator above the two power switches should light up in amber.This indicates that the AVR is in Standby mode and is ready to be turned on. Normally,you may leave the Master Power Switch in the ON position, even when the receiver is not being used. See Figure 50.

Figure 50 – Power Switches

There are several ways in which the AVR 146 may be turned on: a) Press the Standby/On Switch on the front panel. See Figure 50. b) Press the Source Select Button on the front panel. See Figure 51.

To turn the receiver off, press either the Standby/On Switch on the front panel, or press the AVR Button and the OFF Button on the remote. Unless the receiver will not be used for an extended period of time (for example,if you will be on vacation), it is not necessary to turn off the Master Power Switch.When the Master Power Switch is turned off, any settings you have programmed, including system configuration and preset radio stations,will be preserved for up to four weeks.

Sleep Timer

You may program the AVR to play for up to 90 minutes and then turn off automatically using the sleep timer.

Press the Sleep Button on the remote,and the time until turn-off will be displayed. See Figure 53. Each additional press of the Sleep Button will reduce the time until turn-off by 10 minutes,until the OFF setting is reached, which disables the sleep timer.

NOTE: Any time you press one of the remote’s Input Selectors (i.e.,DVD/CD,TAPE/The Bridge, HDMI 1/HDMI 2,VID1, VID2, VID3,AM/FM or 6CH), the remote will switch modes so that it will only transmit the codes programmed to operate that device. To control the receiver, press the AVR Button to return the remote to AVR mode.

If you press the Sleep Button after the timer has been set, the remaining time until turn-off will be displayed.You may press the Sleep Button to change the time until turn-off. Pressing and holding the Sleep Button will disable the sleep timer, and the SLEEP OFF message will appear.

Volume Control

The volume may be adjusted either by turning the knob on the front panel (clockwise to increase volume or counterclockwise to decrease volume), or by pressing the Volume Control Buttons on the remote. See Figure 54.The volume is displayed as a negative number of decibels (dB) below the 0dB reference point, and may be changed in 0.5dB increments.

Unlike the volume controls on some other products,0dB is the maximum volume for the AVR 146. Although it’s physically possible to turn the volume to a higher level, doing so may damage your hearing and your speakers.For certain more dynamic audio materials,even 0dB may be too high, allowing for damage to equipment.

Figure 54 – Volume Controls

AVR146 harman/kardon

OPERATION

The AVR 146 is designed to reproduce audio with a minimum amount of distortion, which may lead you to think that your hearing and the equipment can handle higher volumes.We urge caution with regard to volume levels.

Mute Function

To temporarily mute all speakers and the headphones,press the Mute Button on the remote.See Figure 55. Any recording in progress will not be affected.The MUTE message will flash in the display as a reminder. To restore normal audio,either press the Mute Button again, or adjust the volume.Turning off the AVR will also end muting.

Figure 55 – Mute Button

Tone Controls

You may boost or cut either the treble or the bass frequencies by up to 10dB.

Press the Tone Mode Button once. See Figure 56. This will indicate whether the tone controls are in or out of the circuitry.If you wish to return the tone controls to 0, or “flat”response, press the Buttons,until the TONE OUT message appears, which preserves any changes you have made to the bass or treble settings for later use.To reactivate your changes,the tone control must again be set to TONE IN.

With the TONE IN message displayed,press the Tone Mode Button repeatedly to access TREBLE MODE and BASS MODE.Use the

⁄/¤ Buttons to change the treble or bass settings,as desired.The

display will return to normal a few seconds after your last command.

⁄/¤

NOTE: The AVR 146 does not have a conventional balance control.The speaker output level calibration process compensates for any characteristics of your room or speakers,and we recommend that you leave the settings as they are after you have completed Initial Setup.However, you may manually adjust the levels of the left and right channels – decreasing one and increasing the other by the same amount – using the Channel Adjust submenu, as described on page 31.This achieves the same effect as a balance control.

Headphones

Plug the 1/4" plug on a pair of headphones into the headphone jack on the front of the receiver for private listening.See Figure 57. The first time you use the headphones,the DOLBY H:BP message will be displayed, indicating that Dolby Headphone surround processing is in the bypass mode,which delivers a conventional 2-channel signal to the headphones.

Figure 57 – Headphone Jack

Press the Surround Select Button on the front panel, or the Dolby Button on the remote,to switch to Dolby Headphone virtual surround processing,indicated by the DOLBY H:DH message. Dolby Headphone delivers an enhanced sound field that emulates a 5.1-channel speaker system. No other surround modes are available for the headphones.

OPERATION

The source name will appear in the upper line of the front-panel display. If you retitled the source,only the new title will appear. Otherwise,the audio input assigned to the source (analog or one of the digital audio inputs) will also appear.The surround mode will be displayed on the lower line.The same information will also appear on screen in the semi-OSD, unless you have set the semi-OSD to OFF in the System Setup menu, as described in the Advanced Functions section.

Audio Input Selection

The AVR 146 is programmed at the factory to use the analog audio inputs for each source (except as indicated in Table A1 in the appendix). To assign a digital audio input to a source (if you have not done so using the Input Setup menu during Initial Setup), press the Digital Button on the remote.The current audio input selection will flash in the display, and you may press the inputs.When the desired input appears, press the Set Button to select it. See Figure 59.

Figure 59 – Digital Input Selection

If the Auto Poll feature is ON in the Input Setup menu,and if a digital audio input has been assigned to the source,the AVR 146 will first check the digital audio input for a signal. If a signal is present, the AVR 146 will select the digital audio input.If no signal is present, the AVR 146 will switch to the analog audio inputs for the source.

⁄/¤ Buttons to scroll through the audio

If no signal is present at the component video input, then the S-video or composite video input for the source will be selected. It is not possible to reassign the S-video or composite video inputs to other sources.

For audio-only sources, such as the tuner or CD inputs,when no component video signal is present, the last-used video source will be selected.

6-Channel Direct Inputs

If you wish to hear audio through the 6-Channel Direct Inputs together with video,then connect your multichannel player to the Component Video 1 Inputs,and connect the player’s 6-channel analog audio outputs to the 6-Channel Inputs on the AVR. Assign the component video inputs you selected to the 6-Channel Input source.The AVR will automatically select the correct component video and audio inputs when you select this source.

If you need to use composite or S-video for your multichannel player, e.g., if your video display does not have component video inputs,then you will need to use the video inputs for another source.Since the AVR automatically selects the last-used video inputs for audio sources,you would first select the source you connected the video cables to,and then the 6-Channel Inputs for the audio.

Example 1:You would like to connect a DVD-Audio player to the AVR 146.You plan on playing a variety of discs using this player, including conventional DVDs and even CDs as well as multichannel discs.When playing DVDs and CDs, it is preferable to use a digital audio connection to obtain the best sound quality and the benefit of any digital surround formats contained on the DVD. However,when playing DVD-Audio discs,you will need to use the 6-channel analog audio connections.In addition, some of these discs contain video materials, although the player does not have an HDMI output.

We recommend that you connect this player as follows:

Video Input Selection

When a source is selected, the AVR 146 switches to a video input as follows:

The COMPONENT IN line of the Input Setup menu indicates which of the two component video inputs on the AVR 146 is assigned to each source.All of the sources listed in the left column of the Source Indicators display on the front panel are assigned to the Component Video 2 inputs by default, and the sources listed in the right column default to the Component Video 1 sources. See Figure 60.

Figure 60 – Front-Panel Input Indicators

You may reassign either component video input to another source if it is physically connected to that input, but there is no option to disable the component video inputs for any source.If a signal is present at the component video input assigned to that source,it will be selected. If your device is not using component video,make sure that other devices connected to the component video inputs are turned off.

a) Connect the player’s coaxial digital audio output to the Coaxial 1 input

on the AVR. This input is assigned by default to the DVD source.

b) Connect the player’s component video outputs to the Component

Video 1 inputs on the AVR, which are assigned by default to the DVD source.If your video display doesn’t have component video inputs, then connect the player’s composite or S-video output to the DVD’s corresponding video input.

c) Connect the player’s 6-channel analog audio outputs to the AVR’s

6-Channel Inputs and assign the Component Video 1 inputs to this source using the Input Setup menu, as described in the Initial Setup section.

d) Program the player’s remote control codes into the DVD Input

Selector. Note that not all commands will necessarily be available. When you wish to view a DVD, simply select the DVD source. When you wish to listen to a DVD-Audio disc and view the menus

and other still images on the disc,first select DVD,and then the 6-Channel Inputs as the source.

AVR146 harman/kardon

OPERATION

Example 2: In this example,your multichannel disc player is equipped with an HDMI output. Connect it as follows:

a) Connect the player’s coaxial digital audio output to the Coaxial 2 input

on the AVR. This input is assigned by default to the HDMI 1 source.

b) Connect the player’s HDMI output to the HDMI 1 source input, and

make sure to connect the AVR’s HDMI Output to your video display.

c) Connect the player’s 6-channel analog audio outputs to the AVR’s

6-Channel Inputs and then select an unused component video input at the COMPONENT IN line to avoid inadvertently selecting the video signal from another device.

d) Program the player’s remote control codes into the HDMI 1 Input

Selector. When you wish to view a DVD, simply select the HDMI 1 source. When you wish to play a multichannel disc,first select the HDMI 1

source to obtain the correct video signal, then select the 6-Channel Inputs to select the audio signal.

To select the 6-Channel Inputs as the source,use either the Source Selector on the front panel or press the 6CH Input Selector on the remote.See Figure 61.

Figure 62 – Tuner Input Selection

Radio stations may be selected in one of four ways (see Figure 63):

1. If you know the frequency number, enter it directly by first pressing the Direct Button on the remote,and then using the Numeric Keys.

2.After you have programmed Preset stations (see below), either enter the Preset number (1 through 30) using the remote or use the Preset Stations Button (front-panel or remote), to scroll through the list of presets.

3. In Auto tuning mode, with each press of the Tuning Buttons (frontpanel or remote) the AVR 146 will scan in the chosen direction until a station with acceptable signal strength is detected. Press the Tuning Button again to stop scanning.

4. In Manual tuning mode,with each press of the Tuning Buttons the AVR 146 will tune the next frequency increment (0.1MHz for FM,or 10kHz for AM) in the selected direction.Press and hold the Tuning Button for faster scanning.

Figure 61 – 6-Channel Input Selector

NOTE: The 6-Channel Inputs pass the incoming signals directly to the volume control, without digitizing or processing them. Therefore,you will need to configure bass management settings (i.e.,speaker size,delay and output level) on your source device so that they match the settings you programmed during Initial Setup.Consult the owner’s guide for your multichannel player for more information.

Using the Tuner

The AVR 146’s built-in tuner may be selected in one of three ways (see Figure 62):

1. Press the Source Selector Button on the front panel repeatedly until the tuner is selected.The last-used band (AM or FM) will be active.

2. Press the Tuner Band Button (marked AM/FM).Press this button again to switch bands.

3. Press the Tuner Input Selector (marked AM/FM) on the remote. Press this button again to switch bands.

Figure 63 – Tuning a Station

Press the Tuning Mode Button (TUN-M on the remote) to switch between Auto and Manual tuning modes. See Figure 64.When an FM station has been tuned, pressing the Tuning Mode Button will switch between stereo and mono tuning,which may improve reception of weaker stations.

Figure 64 – Tuning Mode

To store a station in one of the 30 presets (see Figure 65):
