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 inthis manualshould 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.

Table 1– Connection Color Guide

Types of Cables

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

Speaker Cables

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 red 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 145 uses binding-post speaker 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.

Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

Bare wire cables are installed as follows:

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.

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.

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.

Figure 3 – Subwoofer

Connecting Source Devices to the AVR

The AVR 145 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.

In general, 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.

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 commonly used: 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.

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.

Figure 4 – Coaxial Digital Audio

Optical digital audio connectors are normally covered by a shutter to protect them from dust.The shutter opens as the cable is inserted.Input connectors are color-coded using a black shutter, while outputs use a gray shutter.

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. 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 laws regarding copyright if you choose to make a copy for your own personal use.

Figure 6 – Analog Audio

Multichannel analog connections are used with advanced sources where the digital content is copy-protected and all surround processing is performed inside the source.These types of connections are usually used with DVD-Audio,SACD,Blu-ray Disc, HD-DVD and other advanced players.

Figure 7 – Multichannel Analog Audio

Figure 8 – The Bridge

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 separately purchase The Bridge and connect it to The Bridge/DMP port on the receiver. Dock your iPod (not included) in The Bridge,and you may listen to your materials through your high-performance audio system.You may even use the AVR 145 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.

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 source (never more than one at the same time for any source).

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 connect a composite video jack to an analog or coaxial digital audio jack, and vice versa. Both the chrominance (color) and luminance (intensity) components of the video signal are transmitted using a single cable.

CONNECTIONS

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.

Figure 10 – 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 colorcoded green, the “Pb” cable is colored blue and the “Pr”cable is colored red.

Figure 11 – Component Video

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

Antennas

The AVR 145 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.

Figure 12 – FM Antenna

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

Figure 13 – AMAntenna

RS-232 Serial Port

The RS-232 serial port on the AVR 145 is used only for data. If Harman Kardon releases a software upgrade for the receiver’s operating system at some time in the future,the upgrade may be downloaded to the AVR using this port. Complete instructions will be provided at that time.

INSTALLATION

You are now ready to connect your various components to your receiver. Before beginning,make sure that all components, including the AVR 145, 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 playing.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 a cabinet. It is also preferable to stack components on separate shelves rather than 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 145. 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 15 as a reference.

Figure 15 – Speaker Connections

Step Two – Connect the Subwoofer

Connect the Subwoofer Output on the AVR 145 to the line-level input on your subwoofer. Consult the manufacturer’s guide for the subwoofer for additional information.

Figure 16 – Subwoofer Connection

Step Three – Connect the Antennas

Connect the FM and AM antennas to their terminals.

Figure 17 – Antenna Connections

Step Four – Connect the Source Components

Use the worksheets in the Appendix to note which connections you will use for each of your source devices.

For each source, select a source input (Video 1, Video 2, Video 3, etc.). In Table 2 we recommend connecting certain types of sources to certain source inputs to make it easier to program and use the remote control.

Decide which audio connections you will use.If your source device has them, use

either

the coaxial digital or the optical digital audio connection. Referring to Table 2, we recommend you connect the DVD source to the Coaxial 1 input jack, and the source designated Video 2 to the Optical 2 input jack. However, you may make whatever connections are best for your system.

In addition to the digital audio connections,we recommend that you connect the analog audio connections for each source,as a backup to the digital connections.For sources that don’t have digital audio outputs, you must use the analog audio connections.

For each video source, select one type of video connection. Component video is preferred, but both your source device and your video display must have this type of video capability. If either device does not, then use S-video.Again, if either your source device or your video display doesn’t have S-video connections,then use composite video.

Referring to Table 2, we recommend that you connect the DVD source to the Component Video 1 inputs, and any one source designated as Video 1,Video 2 or Video 3 to the Component Video 2 inputs. However, you may make whatever video connections are best for your system.

Video 1 Source

Since this source includes audio and video recording output jacks,it is best suited to a video recorder, such as your VCR or DVR.

Referring to Table 2, connect your recorder to the Video 1 Analog Audio inputs and outputs and to either the Coax 2 or Optical 2 digital audio input (and corresponding digital audio output). Use either the Video 1 S-video or composite video input and output if you wish to make recordings.If you don’t plan on recording, you may use the Component Video 2 inputs.

INSTALLATION

NOTE: It’s possible for a source to use none of the connections named for that source.For example,you might connect your DVD player to the Component Video 1 inputs and the Coax 1 digital audio input. However, we will refer to this source as “DVD”,and in Step Five of the Initial Setup section you will program the receiver so that these connections are assigned to the DVD source.When you select “DVD”as your source using the front panel or the remote,the correct connections for your DVD player will be used.

We recommend connecting your various sources using the connections shown in Table 2 below in order to simplify programming your receiver and remote control. However, you may connect any device to any source input.

Table 2 – Recommended Source Component Connections

AVR145

harman/kardon

INSTALLATION STEPS

NOTE: It isn’t possible to make recordings using component video connections.Keep this in mind as you connect other source devices that you may wish to make recordings from.

Video 2 Source

The Video 2 source is used only for playback,never recording.The AVR145 remote control is programmed to operate many brands and models of cable and satellite television devices,and we recommend connecting your cable or satellite set-top box to this source.

Referring to Table 2, connect your set-top box to the Video 2 Analog Audio inputs and to the Optical 1 Digital Audio input. If possible,use the Component Video 2 inputs. Otherwise,connect the set-top box’s S-video or composite video output to the matching Video 2 video input.

Figure 19 – Video 2 A/V, DIgital Audio and Component Video Inputs

NOTE: If you receive your television programming using your TV with an antenna or direct cable connection, then you will need to connect the analog and optical digital audio (if available on your TV) outputs to the Video 2 Analog Audio inputs and to the Optical 1 Digital Audio input.Do not connect any video output on the television set to any video input on the receiver. See Step Five for information on connecting the receiver’s video monitor outputs to the television.

Video 3 Source

The Video 3 source is used only for playback,never recording. It is also generally reserved for components that are only temporarily connected to the receiver, such as cameras and game consoles.When not in use, you may place the supplied covers over the front-panel Video 3 jacks for a cleaner appearance.Simply snap the covers in place.When you wish to use the jacks,gently press on the left side of each cover to pivot it out for removal.

Referring to Table 2, connect your camera or game console to the Video 3 Analog Audio inputs and to either the Coaxial 3 or Optical 3 digital audio input. If possible,use the Component Video 2 inputs. Otherwise,connect the component’s S-video or composite video output to the matching Video 3 video input.

Figure 20 – Video 3 A/V and Digital Audio Inputs

DVD

The DVD source is used for a DVD player. If you have a more advanced multichannel device,such as a Blu-ray Disc or HD-DVD player,connect it to the DVD source.

Referring to Table 2, connect your DVD player to the DVD Analog Audio inputs and to the Coaxial 1 Digital Audio input.If possible,use the Component Video 1 inputs. Otherwise,connect the DVD player’s S-video or composite video output to the matching DVD video input.

Figure 21 – DVD A/V,DIgital Audio and Component Video Inputs

If your DVD player plays multichannel lossless discs,such as SACD or DVD-Audio,you will also need to connect the 6-channel analog audio outputs on the DVD player to the 6-channel analog audio inputs on the receiver in order to enjoy these discs to their fullest.

Figure 22 – 6-Channel Analog Audio Inputs

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 the Coaxial 2 or Optical 2 Digital Audio input.

Figure 23 – CD Audio Inputs and Digital Audio Inputs

No video connections are made,although if your system has unusual requirements,you may connect a video device using component video outputs to the Component Video 2 inputs on the receiver, if those jacks are not in use by another device.

Tape

The Tape source is used for audio-only recorders, such as a CDR, MiniDisc or cassette deck.

Referring to Table 2, connect your recorder to the Tape Analog Audio inputs and outputs,and to either the Coax 2 or Optical 2 Digital Audio input (and corresponding digital audio output).

With Harman Kardon’s optional The Bridge, you can listen to audio stored on your iPod (not included),use your AVR 145 remote control to operate the iPod,and even charge the iPod while it’s docked in The Bridge.

Simply plug the proprietary cable from The Bridge into the special The Bridge/DMP connector on the rear of the AVR 145’s.Refer to the owner’s manual for The Bridge to select the appropriate insert to match your iPod.

Figure 25 – The Bridge/DMP Connector

Step Five – Connect 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 note 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,you will still need to use one of these two video monitor connections in order to view the AVR 145’s onscreen menus and displays.

First, determine what types of video your display is capable of handling. Remember that component video is preferred, followed by 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.

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. Make a note of how these inputs are labeled on the display.

Figure 26 – Component Video Monitor Outputs

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

Figure 27 – 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,you will need to remember to 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.

You may plug one device into the AC Switched Accessory Outlet on the rear of the AVR 145. Make sure this device draws no more than 50 watts.The device should have its mechanical or master power switch turned on, and it will power on any time the AVR 145 is turned on.

Figure 28 – Switched ACAccesssory Outlet

Before plugging the AVR 145’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.

Step Seven – Insert Batteries in Remote

The AVR 145 remote control uses three AAA batteries, which are included.

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

INSTALLATION

INSTALLATION

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

Figure 29 – Remote Battery Compartment

When using the remote,remember to point the lens toward the front panel of the AVR 145. Make sure no objects, such as furniture,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 145 remote is capable of controlling not only 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 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.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.

At the factory,the AVR 145’s codes and the codes to control an iPod docked in The Bridge are preprogrammed,and the codes for many Harman Kardon DVD and CD players are also preprogrammed. If you have other source devices in your system, follow these steps to program the correct codes into the remote.

1. Using the codes in Tables A9–A16 of the Appendix, look up the product type (e.g. DVD,cable TV box) and the brand name of your source.The number(s) listed are potential candidates for the correct code set for your particular device.

2.Turn on your source device.

3. Put the remote into Program mode by pressing and holding the Input Selector and the Mute button simultaneously until the LED on the remote starts to flash, and then releasing the buttons.

Figure 30 – Input Selectors

4. Enter a code from Step 1 above. a) If the device turns off, then press the Input Selector again to accept

the code,which will flash. The remote will exit the Program mode.

b) If the device does not turn off, tr y entering another code.If you run

out of codes,you may search through all of the codes in the remote’s library for that product type by pressing the

⁄ or ¤

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 accepted 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 programmed a satisfactory code set that operates most of the functions you frequently use.

6.You may find out which code number you have programmed by

pressing and holding the Input Selector and Mute Button simultaneously to enter the Program mode.Then press the Set Button, and the LED will blink in the code sequence.One blink represents “1”, two blinks for “2”,and so forth. A series of many fast blinks represents “0”.Record the codes programmed for each device here.

Table 3 – Remote Control Codes

If you are unable to locate a code set that correctly operates your source device,it will not be possible to use the AVR remote to control that device.However,you may still connect the source to the AVR 145 and operate it using the device’s original remote control.Alternatively, you may wish to consider purchasing Harman Kardon’s optional TC 30 activity-based remote,which is programmed by accessing a large database of product codes on the Internet.The TC 30 is also capable of “learning” codes from your device’s original remote.

Source Input Product Type Remote Control Code

Video 1 VCR, PVR Video 2 Cable,Satellite Video 3 TV DVD DVD CD CD,CDR Tape Cassette

AVR145

harman/kardon

Most of the button labels on the remote describe the button’s function when used to control the AVR 145. However,the button may perfor m a very different function when used to control another device.Refer to the Remote Control Function List,Table A8 in the Appendix, for a list of 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 to the mode for that device. See pages 43 through 44 for instructions on these advanced programming functions.

NOTE: The AVR 145 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. The volume and mute controls operate the AVR when any device except Tape has been selected. You may change this punch-through programming at any time.

Step Nine – Turn On the AVR 145

Two steps are required the first time you turn on the AVR 145.

1. 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.

Figure 31 – Power Switches

2.There are several ways in which the AVR 145 may be turned on from Standby mode.

a) Press the Standby/On Switch on the front panel. b) Press the Source Select Button on the front panel.

Figure 32 – Source Select Button

c) Using the remote,press any one of these buttons: AVR, DVD,CD,

TAPE,VID1,VID2, VID3, AM/FM or 6/8CH.

Figure 33 – AVRand Input Selectors

NOTE: Any time you press one of the Input Selectors on the remote (i.e.,DVD,CD,TAPE,VID1, VID2 or VID3), the remote will switch modes so that it will only transmit the codes programmed to operate that device.In order to control the receiver, you will need to press the AVR button to return the remote to AVR mode.

OPERATION

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 145

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.

Figure 44 – Power Switches

There are several ways in which the AVR 145 may be turned on: a) Press the Standby/On Switch on the front panel. b) Press the Source Select Button on the front panel.

Figure 45 – Source Select Button

c) Using the remote,press any one of these buttons: AVR,DVD, CD,

TAPE,VID1,VID2, VID3, AM/FM, 6/8CH or The Bridge/DMP.

Figure 46 – AVRand Input Selectors

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

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. 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.

Figure 47 – Sleep Button

When the sleep timer has been set, the front-panel display will automatically dim to half-brightness.If you press any button on the remote or front panel, the display will return to full-brightness.The display will dim again several seconds after your last command.

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.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 some volume controls on other products,0dB is the maximum volume for the AVR 145. 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 48 – Volume Controls

AVR145

harman/kardon

OPERATION

Remember that the AVR 145 is designed to reproduce audio with a minimum amount of distortion.This clarity 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.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 49 – Mute Button

Tone Controls

You may boost or cut either the treble or the bass frequencies by up to 10dB in 2dB increments.

Using the front-panel controls or the remote,press the Tone Mode Button once.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 TONEIN.

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.

Figure 50 – Tone Button

You may alternatively adjust the tone controls using the full-OSD menu system. Press the OSD Button on the remote to view the Master Menu. The cursor will be pointing to the INPUT SETUP line; press the Set Button to display that menu.You will be able to view the tone settings.If you wish to make any changes to the TONE,BASS or TREBLE settings, use the arrow keys on the remote to move the cursor to the line you wish to change.Once you have changed the setting using the ‹/› Buttons,simply move the cursor up or down to a different line; it isn’t necessary to press the Set Button to enter the new setting.When you have finished, either wait until the display times out and disappears, press the OSD Button to clear the display, or move the cursor to the

BACK TO MASTER MENU line if you wish to make other changes using the menu system.

NOTE: The AVR 145 does not have any conventional balance control.The EzSet process compensates for any characteristics of your room or speakers,and we recommend that you leave the settings as they are after EzSet has been run. 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 41. 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.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 51 – 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.

Source Selection

Press the front-panel Source Select Button to scroll through the sources.The left side of the button scrolls down the list that appears in the display; the right side scrolls upward. For direct access to the tuner, press the Tuner Band Button, which switches to the last-used band and frequency. For direct access to any source,press its Input Selector on the remote (see Figure 46).

Figure 52 – Source Select and Tuner Band Buttons

NOTE: The Bridge/DMP source has no icon in the Source Indicators display. When selected, the DMP indication will appear in the message display’s upper line, and one of two messages will scroll on the right side to indicate whether The Bridge is unplugged or connected. If you have retitled this source,then only the new name will appear in the upper line.

The AVR 145 will switch to the audio and video inputs assigned to that source.If you set the BASS MGR setting in the Speaker X-over menu to

harman/kardon

OPERATION

INDEPENDENT, the AVR 145 will change the speaker size configuration to the one you programmed for the source.If you selected a surround mode for the source,the AVR 145 will switch to that mode.

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.

Audio Input Selection

The AVR 145 is programmed at the factory to use the analog audio inputs for each source (except for the DVD and Video 2 sources, which default to Coax 1 and Optical 1).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 or front panel. The current audio input selection will flash in the display, and you may press the

⁄/¤ (or ‹/› on the front panel) Buttons to scroll through the

audio inputs.When the desired input appears,press the Set Button to select it.

Figure 53 – Digital Input Selection

If the Auto Poll feature has been left ON in the Input Setup menu,and if a digital audio input has been assigned to the source,the AVR 145 will first check the digital audio input for a signal. If a signal is present, the AVR 145 will select the digital audio input.If no signal is present, the AVR 145 will switch to the analog audio inputs for the source.

Video Input Selection

When a source is selected, the AVR 145 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 145 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.This list appears in Figure 54.

Figure 54 – Front-Panel Input Indicators

You may reassign either component video input to another source,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.

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 (the default for the 6-Channel Inputs), and the correct audio and video inputs will be selected when you select 6CH as your source.If your multichannel player uses S-video or composite video connections,you will first need to select the source you connected the video output to (e.g., DVD), and then select the 6CH source.

Figure 55 – 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 using the Manual Setup menu. Consult the owner’s guide for your multichannel player for more information.

Using the Tuner

The AVR 145’s built-in tuner may be selected in one of three ways:

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.

OPERATION

Radio stations may be selected in one of four ways:

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 frontpanel Preset Stations Button to scroll through the list of presets.

3. In Auto tuning mode, with each press of the Tuning Buttons (frontpanel or remote) the AVR 145 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 145 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 57 – Tuning a Station

Press the Tuning Mode Button (TUN-M on the remote) to switch between Auto and Manual tuning modes.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 58 – Tuning Mode

To store a station in one of the 30 presets:

1.Tune the desired station.

2. Press the Memory Button on the remote.

3. Use the Numeric Keys to enter the desired preset number.

Recording

Two-channel analog and digital audio signals,as well as composite and S-video signals,are normally available at the appropriate recording outputs.Thus,to make a recording, you need only make sure to connect your audio or video recorder to the appropriate output jacks,as described in the Installation section, insert blank media and make sure the recorder is turned on and recording while the source is playing.

NOTES:

1.Analog audio signals are not converted to digital form, and digital audio signals are not converted to analog audio form. However, you may record a coaxial or optical digital audio source using either type of digital audio output.

2. Only PCM digital audio signals are available for recording. Proprietary formats such as Dolby Digital and DTS may not be recorded using the digital audio connections,although if the source is connected to the AVR using the analog audio connections,an analog recording may be made.

3. Component video sources are not available for recording.

4. Please make certain that you are aware of any copyright restrictions on any material you record. Unauthorized duplication of copyrighted materials is prohibited by federal law.

Using

The Bridge is an optional dock that may be used with a compatible iPod (not included).When The Bridge is connected to its proprietary input on the AVR 145 and the iPod is docked, you may play the audio materials on your iPod through your high-quality audio system,operate the iPod using the AVR remote or the AVR’s front-panel controls,view navigation messages on the AVR’s front panel or a connected video display, and charge the iPod.

Either press the front-panel Source Selector repeatedly until the message “DMP/The Bridge is CONNECTED”scrolls across the front panel and semi-OSD displays,or press the DMP Button on the remote to select The Bridge as the input source.
