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.

REMOTE CONTROL FUNCTIONS

The AVR 144 remote is capable of controlling seven devices, including
the AVR itself. During the installation process, you may program the
codes for each of your source components into the remote. Each time
you wish to use the codes for any component, you will need to first
press the Selector Button for that component. This changes the button
functions to the appropriate codes for that product.

Each Input Selector has been preprogrammed to control certain types
of components, with only the codes specific to each brand and model
changing, depending on which product code is programmed. The
device types programmed into each selector may not be changed.

DVD: Controls DVD players and recorders.

CD: Controls CD players and recorders.

Tape: Controls cassette decks.

Video 1: Controls VCRs, TiVo

®

and DVRs.

Video 2: Controls cable and satellite television set-top boxes.

Video 3: Controls televisions and other video displays.

For example, if you have inserted a disc in your CD player and you
would like to skip ahead three tracks, but you then find that the volume
is too loud, you would follow this procedure:

1. Press the CD Input Selector to switch to the codes that control your

CD player.

2. Press the Play Button (in the Transport Controls section) if the disc is

not already playing.

3. Press the Skip Up Button three times to advance three tracks.

4. Press the AVR Button so that you can access the Volume Controls.

5. Press the Volume Down Button until the volume level is satisfactory.

Any given button may have different functions, depending on which
component is being controlled. Some buttons are labeled with these
functions. For example, the Sleep and DSP Surround Buttons are
labeled for use as Channel Up/Down Buttons when controlling a televi­sion or cable box. See Table A8 in the appendix for listings of the
different functions for each type of component.

IR Transmitter Lens: As buttons are pressed on the remote,

infrared codes are emitted through this lens. Make sure it is pointing

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 Connections

Speaker cables carry an amplified signal from the receiver’s speaker
terminals to each loudspeaker. Speaker cables 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 144 uses binding-post speaker
terminals that can accept banana plugs

Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

16

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.

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.

Figure 3 – Subwoofer

Connecting Source Devices to the AVR

The AVR 144 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.

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. See Figure 4.

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. See Figure 5.

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.

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. See Figure 7.

Figure 7 – Multichannel Analog Audio

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 in 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, and
vice versa. Both the chrominance (color) and luminance (intensity)
components of the video signal are transmitted using a single cable.
See Figure 8.

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 will 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 8 – 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 9.

Figure 9 – 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. See Figure 10.

Antennas

The AVR 144 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 11.

INSTALLATION

You are now ready to connect your various components to your receiver.
Before beginning, make sure that all components, including the AVR 144,
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 144.
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. See Figure 14.

Figure 14 – Speaker Connections

Step Two – Connect the Subwoofer

Connect the Subwoofer Output on the AVR 144 to the line-level input on
your subwoofer. See Figure 15. Consult the manufacturer’s guide for the
subwoofer for additional information.

Step Three – Connect the Antennas

Connect the FM and AM antennas to their terminals. See Figure 16.

Figure 16 – 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
tion. 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 1 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.

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.

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 any available Coax or Optical digital audio
input. See Figure 17. Use either the Video 1 S-video or composite

NOTES:

1. 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.

2. The AVR 144 does not have any digital audio outputs. If you
wish to make recordings, your source must be connected to
any of the AVR 144’s analog audio inputs, and your recorder
must be connected to either the Video 1 or Tape Analog
Audio Outputs. The AVR 144 will not convert a digital audio
input signal to analog.

Video 2 Source

The Video 2 source is used only for playback, never recording. The
AVR 144 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.
See Figure 18.

Figure 19 – 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.
See Figure 20.

Figure 20 – 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. See Figure 21.

Figure 18 – 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 audio (if available on your TV) outputs to
the Video 2 Analog Audio inputs. 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. See Figure 19.

22

Figure 21 – 6-Channel Analog Audio Inputs

CD

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. See
Figure 22.

Figure 22 – 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.

See Figure 23.

Figure 23 – Tape Audio Inputs and Outputs, and Digital Audio Inputs

NOTE: You will not be able to make digital audio recordings using
the AVR 144. Make sure your source is connected to any of
the AVR 144’s analog audio inputs, and connect your recorder

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 144’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. See Figure 24.

Figure 24 – 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.
See Figure 25.

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.
See Figure 25.

Figure 25 – 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.

Before plugging the AVR 144’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 144 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.

Insert the batteries as shown in the diagram, making sure to observe
the correct polarity. See Figure 26.

Figure 26 – Remote Battery Compartment

When using the remote, remember to point the lens toward the front
panel of the AVR 144. 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.

23

20

AVR144 harman/kardon

INSTALLATION

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 144 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.

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 144’s codes and the codes to control many
Harman Kardon DVD and CD players are 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–A15 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. See Figure 27.

Figure 27 – 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, try 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
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

⁄ or ¤

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 144
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.

Most of the button labels on the remote describe the button’s function
when used to control the AVR 144. 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 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 42 – 43 for instructions on these advanced programming
functions.

NOTE: The AVR 144 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 144

Two steps are required the first time you turn on the AVR 144.

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, indicating that the AVR is in Standby mode and is
ready to be turned on. See Figure 28. Normally, you may leave the
Master Power Switch in the ON position, even when the receiver is
not being used.

Figure 28 – Power Switches

2. There are several ways in which the AVR 144 may be turned on from
Standby mode.

a) Press the Standby/On Switch on the front panel. See Figure 28.

b) Press the Source Select Button on the front panel. See Figure 29.

Figure 29 – Source Select Button

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

TAPE, VID1, VID2, VID3, AM/FM or 6CH. See Figure 30.

Figure 30 – AVR and 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.

You are now ready for Initial Setup, in which you will make a few adjust­ments to ensure that your new AVR 144 receiver performs at its best.

25

AVR144 harman/kardon

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 144

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 41.

Figure 41 – Power Switches

There are several ways in which the AVR 144 may be turned on:

a) Press the Standby/On Switch on the front panel. See Figure 41.

b) Press the Source Select Button on the front panel. See Figure 42.

Figure 42 – Source Select Button

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

TAPE, VID1, VID2, VID3, AM/FM or 6CH. See Figure 43.

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. See Figure 44.

Figure 44 – 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. See
Figure 45. 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 144. 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 43 – AVR and Input Selectors

NOTE: Any time you press one of the remote’s Input Selectors
(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.

Figure 45 – Volume Controls

23

AVR144 harman/kardon

OPERATION

Remember that the AVR 144 is designed to reproduce audio with a
minimum amount of distortion. This clarity may lead you to believe 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 46. 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 46 – 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 remote, press the Tone Mode Button once. See Figure 47.
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.

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 144 does not have any conventional balance
control. The 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 the speakers have
been calibrated. 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.
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 48. 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 48 – 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

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 (see Advanced Functions section).

Audio Input Selection

The AVR 144 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. The current audio
input selection will flash in the display, and you may press the

⁄/¤

Buttons to scroll through the audio inputs. When the desired input
appears, press the Set Button to select it. See Figure 50.

Figure 50 – 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 144 will
first check the digital audio input for a signal. If a signal is present, the
AVR 144 will select the digital audio input. If no signal is present, the
AVR 144 will switch to the analog audio inputs for the source.

Video Input Selection

When a source is selected, the AVR 144 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 144 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 51.

Figure 51 – 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, and connect the player’s 6-channel analog audio outputs
to the 6-Channel Inputs on the AVR. Assign the Component Video 1
input 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,
first select the source you connected the video cables to, and then
the 6-Channel Inputs for the audio.

Example: You would like to connect a DVD-Audio player to the AVR 144.
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.

We recommend you connect this player as follows:

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
and 6-Channel Input sources. 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.

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 select the 6-/8­Channel Inputs as the source. See Figure 52.

AVR144 harman/kardon

Figure 52 – 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.

Figure 54 – 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. See
Figure 55.

OPERATION

Using the Tuner

The AVR 144’s built-in tuner may be selected in one of three ways (see
Figure 53):

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 55 – Tuning Mode

To store a station in one of the 30 presets (see Figure 56):

1. Tune the desired station.

2. Press the Memory Button on the remote.

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

Figure 53 – Tuner Input Selection

Radio stations may be selected in one of four ways (see Figure 54):

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 144 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 144 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 56 – Storing a Preset Station

Recording

Two-channel analog 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.

2. The AVR 144 is not designed to make digital audio record­ings. Make sure your source device is connected to one of
the AVR 144’s analog audio inputs, and connect your
recorder to either the Video 1 or Tape analog audio outputs.

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.

Selecting a Surround Mode

Surround mode selection can be as simple or sophisticated as your
individual system and tastes. Feel free to experiment with the many
available surround modes on the AVR 144, and you may find a few that
become your favorites for certain sources or program types. Although
more detailed information on surround modes may be found in the
Advanced Functions section, it is easy to select any of the modes
available at a given time:

To select a surround mode using the front-panel controls, press the
Surround Mode Button repeatedly until the desired group of modes is
selected: Logic 7, Dolby, DTS, DSP or Stereo. Then press the Surround
Select Button repeatedly to select the desired mode within the group.
See Figure 57.

Figure 57 – Select a Surround Mode (Front Panel)

To select a surround mode using the remote control, locate the button
dedicated to the desired group of modes: Logic 7, Dolby Sur, DTS Sur,
DTS Neo:6, Surr (DSP) or Stereo. Press that button repeatedly to select
the desired mode. See Figure 58.

To select a surround mode using the full-OSD menu system, press the
OSD Button to display the Master Menu. Navigate to the SURROUND
SELECT line and press the Set Button to view the Surround Select
menu. Each of the major surround mode groups is listed here. Select
that group to access the MODE setting for selection of an individual
