AVR347 harman/kardon

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

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

semiconductor "chip" components.

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

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

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

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

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

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

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

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

sufficient to damage ES devices.

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

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

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

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

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

CAUTION :

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

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

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

Each precaution in this manual should be followed during servicing.

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

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

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

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

SAFETY PRECAUTIONS

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

LEAKAGE CURRENT CHECK

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

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

REAR-PANEL CONNECTIONS

AM and FM Antenna Terminals: Connect the included AM and

FM antennas to their respective terminals for radio reception.

XM Antenna Jack: Plug in an XM antenna module here. The XM

antenna module is purchased separately, and should specify that it is for home use with an XM Ready the XM service, which is available separately, and activate the service for your antenna module. (XM service is not available in Alaska and Hawaii.)

product. You will need to subscribe to

Front, Center and Surround Speaker Outputs: Use two-

conductor speaker wire to connect each set of terminals to the correct speaker. Remember to observe the correct polarity (positive and negative connections). Always connect the positive lead to the colored terminal on the receiver and the red terminal on the speaker. Connect the negative lead to the black terminal on both the receiver and the speaker. See the Connections section for more information on connecting your speakers.

Surround Back/Multiroom Speaker Outputs: These speaker

outputs may be used either for the surround back channels in a 7.lchannel home theater, or they may be reassigned to a remote room for use with a multiroom system. When these outputs are reassigned for multiroom operation, only a 5.1-channel configuration will be available in the main listening room. Use the on-screen menu system to configure these channels as desired.

As with the other speaker outputs, remember to observe proper polarity by connecting the positive and negative output terminals to the corresponding terminals on each speaker.

Remote IR Carrier Output: This output is similar in function to

the Remote IR Output, with the difference that this jack outputs the full infrared signal as received by the AVR’s IR sensor or the Remote IR Input, while the Remote IR Output jack outputs a “stripped” signal that has no carrier frequency. The full signal may be required by some components with IR inputs. It may also be required when you connect external IR emitters or other devices to the AVR to pass IR signals to other components.

Multiroom Audio Outputs: Connect these jacks to an external

amplifier to power the speakers in the remote zone of a multiroom system. When these jacks are used, it is possible to have a full 7.1channel system in the main listening room at the same time the multiroom system is in use.

A-BUS Port: Use a Category 5/5e cable to connect this port to

optional A-BUS equipment for multiroom operation. When the A-BUS system is used, it is possible to have a full 7.1-channel system in the main listening room at the same time the multiroom system is in use.

Video 1, Video 2, Video 3 and DVD Audio/Video Inputs:

These jacks may be used to connect your video-capable source components (e.g., VCR, DVD player, cable TV box) to the receiver. Remember to use only one type of video connection for each source. See the Connections section for more information on audio and video connection options for each source component.

Video 1 Audio/Video Outputs: These jacks may be used to

connect your VCR or another recorder.

Subwoofer Output: If you have a powered subwoofer with a line-

level input, connect it to this jack.

Preamp Outputs: Connect these jacks to an external amplifier if

more power is desired.

Surround Back/Multiroom Preamp Outputs: These outputs

may be used with an external amplifier either to power the surround back channels, or to power the speakers in the remote zone of a multichannel system. Use the on-screen menu system to configure these channels as desired.

Remote Infrared (IR) Input and Output: When the remote IR

receiver on the front panel is blocked, such as when the AVR is placed inside a cabinet, connect an optional IR receiver to the Remote IR Input jack for use with the remote control. The Remote IR Output may be connected to the Remote IR Input of a compatible source device (or other product) to enable remote control through the AVR. This is particularly useful in multiroom applications, when you wish to control the source device from the remote room (when used with the Multiroom IR Input). When several source devices are used, connect them in “daisy chain” fashion.

Multiroom Infrared (IR) Input: Connect a remote IR receiver

located in the remote zone of a multiroom system to this jack to control the AVR and any source devices connected to the Remote IR Output from the remote zone.

Composite and S-Video Monitor Outputs: If any of your

sources use composite or S-video connections, you may need to connect one or both of these monitor outputs to the corresponding inputs on your television or video display in order to view the sources and to view the on-screen displays. If your video display is equipped with component video or HDMI inputs, you may take advantage of the AVR 347’s transcoding capability, which transcodes composite and S-video signals to component video and HDMI, allowing for only a single video connection from the AVR to the video display.

HDMI Inputs and Output: HDMI (High-Definition Multimedia

Interface) is a newer type of connection for transmitting digital audio and video signals between devices.With the AVR 347’s powerful processor, you may connect up to two HDMI-equipped source devices to the HDMI inputs using a single-cable connection, while benefiting from superior digital audio and video performance. However, if your video display is not HDMI-compatible, you will need to connect the device to one of the other source inputs, selecting a coaxial or optical digital audio input and analog video input. See the Connections and Installation sections for more information.

If your video display has an HDMI input, but some of your sources have only analog video outputs, you may still rely on just the HDMI video connection to your display; the AVR 347 will automatically transcode analog video signals up to 720p to the HDMI format. High-resolution analog 1080i or higher signals are not available at the HDMI Output.

REAR-PANEL CONNECTIONS

The AVR 347 is Simplay HD-verified for compatibility via the HDMI connection with other Simplay HD-verified products.

CD and Tape Audio Inputs: These jacks may be used to connect

audio-only source components (e.g., CD player, tape deck). Do not connect a turntable to these jacks without a phono preamp.

Tape Outputs: These jacks may be used to connect a CDR or

another audio-only recorder.

Coaxial and Optical Digital Audio Inputs: If a source has

a compatible digital audio output, connect it to one of these jacks for improved audio performance. Use only one type of digital audio connection for each source.

Coaxial and Optical Digital Audio Outputs: If a source is also

an audio recorder, you may connect a compatible digital audio output to the recorder’s input for improved recording quality.

The Bridge/DMP Input: Connect the optional Harman Kardon

to this input for use with your iPod (not included). Make sure the receiver is turned off (in Standby mode) when connecting The Bridge.

6-/8-Channel Inputs: Connect the multichannel analog audio

™

outputs of a DVD-Audio, SACD (or any other external decoder) to these jacks to enjoy these proprietary formats.

NOTE: When an HD-DVD or Blu-ray Disc player has an onboard digital decoder, it is not necessary to connect it to the 6-/8-Channel Analog Audio Inputs. Only a digital audio connection (HDMI, coaxial or optical) is needed.

• Due to the design of some video displays, analog 480p or 720p component video source signals may produce artifacts when used with the AVR’s analog video outputs (composite, S-video or component video). If this occurs, try changing the Video Mode setting in the INPUT SETUP menu, or connecting the source device’s video output directly to your video display. However, for best results, we recommend you consider upgrading to an HDMI-capable video display.

RS-232 Serial Port: This specialized connector may be used with

your personal computer in case Harman Kardon offers a software upgrade for the receiver at some time in the future.

RS-232 Mode: Leave this switch popped out in the Operate position

unless the AVR 347 is being upgraded.

RS-232 Reset: This switch is only used during a software upgrade.

A standard processor reset is performed by pressing and holding the front-panel Tone button.

Switched AC Accessory Outlet: You may plug the AC power

cord of one source device into this outlet, and it will turn on whenever you turn on the receiver. Do not use a source that consumes more than 50 watts of power.

AC Power Cord Input: After you have made all other connections,

plug the AC power cord into an unswitched outlet. Plug the female end of the cord into this receptacle, which conveniently allows you to install all wiring ahead of time.

Component Video Inputs: If both a video source (e.g., DVD

player or HDTV tuner) and your television or video display have analog component video (Y/Pb/Pr) capability and if you are not using HDMI connections for the device, then you may connect the component video outputs of the source to one of the two component video inputs. Do not make any other video connections to that source.

Component Video Monitor Outputs: If you are using one of

the Component Video Inputs and your television or video display is component-video-capable and if you are not connecting the HDMI output to our display, you may connect these jacks to the corresponding inputs on your video display.

NOTES:

• Due to copy-protection restrictions, there is no output at the Component Video Monitor Outputs for copy-protected sources.

• High-resolution 1080i and 1080p video signals are not available at the HDMI Output, and are downconverted to 720p for the Component Video Outputs. If your source output is analog high-resolution video, either use the Component Video Outputs, lower the output resolution of your source device, or connect your source’s component video outputs directly to your video display.

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 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 Connections

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

Speaker Connections

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

The differentiation is important because each speaker must be connected to the receiver’s speaker-output terminals using two wires, one positive (+) and one negative (–), referred to as 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 347 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. See Figure 1.

Figure 1 – Binding-Post Speaker Terminals With Banana Plugs

) has established

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. Hand-tighten the cap 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 any other devices. Although doing so won’t cause any harm, performance will suffer.

Figure 3 – Subwoofer

Connecting Source Devices to the AVR

The AVR 347 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 and the XM antenna module.

Separate connections are required for the audio and video portions of the signal, except for digital HDMI connections. 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 three types of digital audio connections: HDMI, coaxial and optical. Any one type of digital audio connection may be used for each source device, but never more than one for the same source. However, it’s okay to make both analog and digital audio connections at the same time to the same source.

NOTE: Since the AVR 347 is capable of processing the audio and video portions of most HDMI signals, if your video display device has an HDMI input, you may make a single HDMI connection from your HDMI 1.1-or-higher source device (such as a DVD player) to the AVR. In that case, no separate digital audio connection is required. Make sure to turn the volume on your television all the way off.

Digital Audio

The AVR 347 is equipped with two HDMI (High-Definition Multimedia Interface) inputs, and one output. HDMI is capable of carrying digital audio and video information using a single cable, thus delivering the highest possible quality picture and sound.

The AVR 347 is Simplay HD-verified for compatibility via the HDMI connection with other Simplay HD-verified products.

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

In addition, receivers and processors such as the AVR 347 may handle the incoming signal in several different ways, depending on their capability as well. Thanks to its powerful processor, the AVR 347 is capable of processing both the audio and video components of the HDMI data, minimizing the number of cable connections in your system.

NOTE: Some multichannel audio devices, such as DVD-Audio, SACD, HD-DVD or Blu-ray Disc players, output some audio formats only through the source’s multichannel analog outputs. These include DVD-Audio players with HDMI version 1.0, and HD-DVD and Blu-ray Disc players that do not decode the digital audio. In those cases, make a separate analog audio connection in addition to the HDMI connection, which is still used for video or if you wish to listen to Dolby Digital, DTS or PCM materials that may be stored on the disc.

IMPORTANT NOTE: The AVR 347 cannot convert 1080i or 1080p analog video signals to the HDMI format, and downconverts them to 720p for the Component Video Outputs. This affects users

of Microsoft

Xbox®360 systems and some older set-top boxes.

If your digital cable television set-top box outputs 1080i or better video via component video outputs and is not equipped with an HDMI output, contact your cable operator for a replacement.

For Xbox 360 and satellite television customers, either change the settings on your source device to ensure that it outputs only 720p video through its component video outputs, which the AVR can convert to the HDMI format, or connect the AVR’s Component Video Monitor Outputs to the video display. Although you could connect the source device’s component video outputs directly to your video display, you would then have to select the correct video input on the display, depending on which source input on the AVR was in use.

The physical HDMI connection is simple.The connector is shaped for easy plug-in (see Figure 4). If your video display has a DVI input, you may use an HDMI-to-DVI adapter (not included) to connect it to the AVR’s HDMI Output.

Figure 4 – HDMI Connection

HDMI cable runs are usually limited to about 10 feet. The AVR 347 incorporates a repeater, which allows an additional 10 feet of cable between the source device and the video display.

If your video display or source device is not HDMI-capable, use one of the analog video connections (composite,S- or component video) and if available on your source device, either a coaxial or optical digital audio connection.

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 5.

Figure 5 – Coaxial Digital Audio

Optical digital audio connectors are often 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. See Figure 6.

In addition, the AVR 347 will convert analog video signals to the HDMI format, upscaling to high-definition 720p resolution. Source signals with 1080i or 1080p resolution are passed via the HDMI Output to your display at their original high-quality resolution, depending on your display’s capabilities. You may view the AVR 347’s own on-screen display menus using the HDMI output.

Figure 6 – 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 all 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.

CONNECTIONS

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 7.

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.

The analog audio connection is strongly recommended if you intend to use the source with the multiroom system. It’s required if you will be using the multiroom preamp outputs with an external amplifier to power your remote speakers, as the AVR 347’s multiroom system is not capable of converting the digital signal to analog format. It’s suggested that you also use the analog audio connections when using the surround back/multiroom speaker outputs, in case another two-channel digital audio source is in use in the main listening area. The AVR 347 is only capable of processing one PCM source at a time.

If you wish to record materials from DVDs or other copy-protected sources, you may only do so using analog connections. Remember to comply with all copyright laws, if you choose to make a copy for your own personal use.

Figure 9 – The Bridge

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).

Digital Video

If you have already connected a source device to one of the HDMI inputs as explained in the Digital Audio Connections section, then you have automatically made a video connection at the same time, as the HDMI signal includes both digital audio and video components.

If the source device is not capable of transmitting its digital audio signal through the HDMI connection, then use one of the coaxial or optical digital audio inputs for the source.

Figure 7 – Analog Audio

Multichannel analog connections are used with some high-definition sources where the copy-protected digital content is decoded inside the source.These types of connections are usually used with DVD-Audio, SACD, Blu-ray Disc, HD-DVD and other multichannel players. See Figure 8. However, the multichannel analog audio connection is not required for DVD-Audio players compliant with HDMI version 1.1 or better, or HD-DVD and Blu-ray Disc players that decode the digital audio internally and output linear PCM signals in digital format. Consult the owner’s guide for your disc player for more information.

Figure 8 – Multichannel Analog Audio

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. See Figure 9. Dock your iPod (not included) in The Bridge, and you may listen to your audio materials through your high-performance audio system. If your iPod is photoor video-capable, you may view still images or video materials stored on the iPod using your home theater system. You may even use the

If a multichannel analog audio connection is required for certain lossless formats (e.g., DVD-Audio, SACD, HD-DVD or Blu-ray Disc), you may make both connections, but you must also make an analog video connection. To listen to the multichannel disc, first select the analog video source input, then select the 6-/8-channel analog audio inputs, and the AVR will retain the last video source you selected other than HDMI.

The AVR 347 is Simplay HD-verified for compatibility via the HDMI connection with other Simplay HD-verified products.

Figure 4 (repeated) – HDMI Connection

Analog Video

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

Figure 10 – Composite Video

S-video, or “separate” video, transmits the chrominance and luminance components using separate wires contained within a single cable.The

plug on an S-video cable contains four metal pins, plus a plastic guide pin. Be careful to line up the plug correctly when you insert it into the jack on the receiver, source or video display. See Figure 11.

Figure 11 – S-Video

Component video separates the video signal into three components – one luminance (“Y”) and two sub-sampled 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 12.

Figure 12 – Component Video

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

NOTES:

• Due to copy-protection restrictions, there is no output at the Component Video Monitor Outputs for copy-protected sources.

• High-resolution 1080i and 1080p video signals are not available at the HDMI Output, and are downconverted to 720p for the Component Video Outputs. If your source outputs analog high-resolution video, either use the Component Video Outputs, change the output resolution of your source device to 720p, or connect your source’s component video outputs directly to your video display.

• Due to the design of some video displays, analog 480p or 720p component video source signals may produce artifacts when used with the AVR’s analog video outputs (composite, S-video or component video). If this occurs, try changing the Video Mode setting in the INPUT SETUP menu, or connecting the source device’s video output directly to your video display. However, for best results, we recommend that you consider upgrading to an HDMI-capable video display.

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

Figure 14 – AM Antenna

RS-232 Serial Port

The RS-232 serial port on the AVR 347 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.

Antennas

The AVR 347 uses separate terminals for the included FM and AM antennas that provide proper reception for the tuner.

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

INSTALLATION

You are now ready to connect your various components to your receiver. Before beginning, make sure that all components, including the AVR 347, are turned completely off and their power cords are unplugged. Don’t

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

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

Step One – Connect the Speakers

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

Connect the center, front left, front right, surround left, surround right, surround back left and surround back right loudspeakers to the corresponding speaker terminals on the AVR 347. See Figure 17. 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 19 as a reference.

Step Three – Connect the Antennas

Connect the FM and AM antennas to their terminals. If you have purchased an XM antenna module designed for connection to an XM Ready device, such as the AVR 347, you may connect it now.To enjoy XM Radio, remember to purchase a subscription and activate your antenna module. More information is available at www.xmradio.com.See Figure 19.

Figure 19 – Antenna Connections

Step Four – Connect the Source Components

Use the Table A4 worksheet in the Appendix to note which connections you will use for each of your source devices.

Figure 17 – Speaker Connections

NOTE: If you only have one surround back speaker, wait until after you have run EzSet/EQ in the Initial Setup section before connecting it to the Surround Back Left speaker outputs.

Step Two – Connect the Subwoofer

Connect the Subwoofer Output on the AVR 347 to the line-level input on your subwoofer. See Figure 18. Consult the manufacturer’s guide for the subwoofer for additional information.

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

one of the HDMI, coaxial digital or the optical digital audio connection. Referring to Table 2, we recommend that you connect the DVD source to the Coaxial 1 input jack, and the source designated Video 2 to the Optical 1 input jack. If you are using the HDMI inputs, then in most cases no other audio connection is required. If your source outputs video but not audio via its HDMI connection, then select any available digital audio input on the AVR to use with the source. If your HDMI source plays DVD-Audio, SACD, HD-DVD, Blu-ray Discs or another multichannel audio format, connect its multichannel analog audio outputs to the AVR 347’s 6-/8-Channel Inputs, and connect one of its analog video outputs to a source input on the AVR 347 (e.g., Component Video 3 or Video 3). When you select that source input, e.g., Video 3, select the 6-/8-Channel Inputs, and the AVR will automatically use the analog video input.

NOTE: The multichannel analog audio connection is not required for DVD-Audio players compliant with HDMI version 1.1 or better, or HD-DVD and Blu-ray Disc players that decode the digital audio internally and output linear PCM signals in digital format. Consult the owner’s guide for your disc player for more information.

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 recording, for use with the multiroom system, or in the event that you use all eight of the digital audio inputs for other devices. For sources that don’t have digital audio outputs, you must use

Figure 18 – Subwoofer Connection

the analog audio connections.

AVR347 harman/kardon

INSTALLATION

For each video source, select one type of video connection. HDMI 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 component video, S-video or composite video.

Referring to Table 2, we recommend that you connect the DVD source to the Component Video 1 inputs, the Video 1 source to the Component Video 2 inputs, and the Video 2 source to the Component Video 3 inputs. Any HDMI-capable source devices should be connected to one of the two HDMI inputs.All other source devices should be connected to either the component, S- or composite video input for that source. 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 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.

NOTE: The AVR 347 is equipped with a total of eight digital audio inputs, not including the HDMI inputs: six on the rear panel (Coaxial 1, 2 and 3, Optical 1, 2 and 3) and two on the front panel (Coaxial 4 and Optical 4). However, there are a total of nine sources that may be connected to devices that have digital audio outputs.We recommend certain digital audio connections simply because, as reflected in Table A1 of the Appendix, those digital audio inputs are assigned to those sources by default at the factory. But any digital audio input (except HDMI) may be reassigned to any source. Since you may not be using all nine source inputs, you may reassign a digital audio input that is recommended for a source you aren’t using to another device. Table 2 is a guide; you may need to make adjustments to fit 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/PVR.

Referring to Table 2, connect your recorder to the Video 1 Analog Audio inputs and outputs input (and corresponding digital audio output). See Figure 20. 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.

IMPORTANT NOTE FOR MICROSOFT®XBOX®360 USERS:

The Microsoft Xbox 360 gaming system is capable of outputting high-definition 1080i and 1080p video signals using the analog component video outputs. Since the AVR 347 is not capable of converting these analog component video signals to the HDMI format, and downconverts them to 720p for the Component Video Outputs, to view your Xbox 360’s video output, either connect the Xbox’s component video outputs to your video display, or change your Xbox 360’s settings so that it outputs 720p video, which the AVR 347 can then convert to the HDMI format.

If the source device is not capable of outputting digital audio via its HDMI output, connect its coaxial or optical digital audio output to an available input on the AVR. If the source device plays multichannel discs (e.g., DVD-Audio, SACD, HD-DVD, Blu-ray Disc), connect its multichannel analog audio outputs to the AVR 347’s 6-/8-Channel Inputs (but see note above). Connect one of the source’s analog video outputs to a source input on the AVR (e.g., Component Video 3 or Video 3) and select that source input, then select the 6-/8-Channel Inputs for audio; the AVR 347 will retain the last video selection other than HDMI. See Figure 26.

The AVR 347 is Simplay HD-verified for compatibility via the HDMI connection with other Simplay HD-verified products.

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

Figure 24 – DVD A/V, Digital Audio and Component Video Inputs

If your DVD player plays multichannel lossless discs, such as SACD or DVD-Audio, or when an HD-DVD or Blu-ray Disc player is used, you may also need to connect the 6- or 8-channel analog audio outputs on the player to the 6-/8-channel analog audio inputs on the receiver, in order to enjoy these discs to their fullest. See Figure 25.

Figure 25 – 6-/8-Channel Analog Audio Inputs

HDMI 1 and 2

The HDMI sources are used with devices that are capable of outputting digital, audio and video through an HDMI connection, such as an HD-DVD or Blu-ray Disc player or HDTV tuner. The HDMI 1 and 2 sources are not used with any of the 2-channel analog audio or video inputs on the AVR 347.

Figure 27 – CD Audio Inputs and Digital Audio Inputs

No video connections are needed.

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 any available digital audio input (and corresponding digital audio output). See Figure 28.

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 347. See Figure 29. Refer to the owner’s manual for The Bridge to select the appropriate insert to match your iPod.

Figure 29 – 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 Video 3 Source on page 26).

If you used an HDMI video connection for any of your sources, then connect the HDMI Output on the AVR to an HDMI input on your video display. See Figure 30. Consult the owner’s guide for your television to learn the proper procedure for disabling or muting the audio. Unless you have a non-HDMI source device that outputs 1080i or higher video via an analog component video connection (see note below), no other video connections are required, thanks to the AVR 347’s ability to transcode analog video signals to HDMI, and you may proceed to Step Six.

IMPORTANT NOTE: The AVR 347 cannot convert 1080i or 1080p analog video signals to the HDMI format and downconverts them to 720p for the Component Video Outputs. This affects users of Microsoft Xbox 360 systems and some older set-top boxes.

If your digital cable television set-top box outputs 1080i or higher video via component video outputs only contact your cable operator for a replacement unit equipped with an HDM output.

For Xbox 360 or satellite receivers with no HDMI output, change the settings on your source device so that it outputs only 720p video through its component video outputs, which the AVR can convert to the HDMI format. Although you could connect the source device’s component video outputs directly to your video display, you would then have to select the correct video input on the display to match the AVR’s input.

If you used component video for any sources, connect the Component Video Monitor Outputs on the receiver to one set of component video inputs on your display. See Figure 31. The AVR 347 is able to transcode composite and S-video sources to component video. If your video display has component video inputs, then you need only to connect the Component Video Monitor Outputs and you may proceed to Step Six.

Figure 31 – Component Video Monitor Outputs

If you used S-video for any sources, connect the S-video Monitor output on the receiver to an S-video input on your display. See Figure 32. The AVR 347 converts composite video sources to S-video. If your video display has S-video inputs, then you need only to connect the S-Video Monitor Output and you may proceed to Step Six.

If you used composite video for any sources, but not component video or S-video, connect the Composite Video Monitor output on the receiver to a composite video input on the display. See Figure 32.

Figure 32 – S-Video and Composite Video Monitor Outputs

Consult the manual for your TV to make sure you understand how to select each video input.

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 347. See Figure 33. 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 347 is turned on.

Figure 30 – HDMI Output

If your television does not have HDMI or DVI video inputs, you will need to make a video connection for each type of video used for your sources.

First, determine what types of video your display is capable of handling. 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, disconnect the source and use a video connection that’s compatible with your display.

Figure 33 – Switched AC Accessory Outlet

Before plugging the AVR 347’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.

The AVR 347 is equipped with a detachable power cord. It allows you to fully wire your system before installing the AVR, which may be required for some in-wall entertainment centers or custom applications. The male end of the cord should be plugged into an unswitched AC power outlet, and the female end should be plugged into the receptacle on the AVR 347’s rear panel. See Figure 34.

AVR347 harman/kardon

INSTALLATION

You may have noticed that three of the Input Selectors look different from the others (see Figure 36). For the DVD/CD, TAPE/The Bridge and HDMI 1/HDMI 2 Selectors, there is a primary source, the name of which is printed on the button, and a secondary source, the name of which is printed in green above the button.

Figure 34 – AC Power Input

Step Seven – Insert Batteries in Remote

The AVR 347 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 toward the top of the remote.

Insert the batteries, as shown in Figure 35, making sure to observe the correct polarity.

Figure 35 – Remote Battery Compartment

When using the remote, remember to point the lens toward the front panel of the AVR 347. 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.

When the remote is in the device mode for the primary source, e.g., DVD, pressing the device selector will cause it to light up in red. When the remote is in the secondary source’s device mode, the selector will light up in green when pressed.

To switch between the primary and secondary device modes, press the selector twice quickly in succession. The selector will retain this selection until the next time you toggle between the primary and secondary device modes.That is, if you press the DVD/CD Selector twice quickly so that the CD source is activated, then press another source selector, such as Video 1, the next time you press the DVD/CD Selector, the remote will return to the CD device mode.

The AVR 347’s remote is factory-programmed to control an iPod docked in The Bridge and many Harman Kardon DVD and CD players. If you have other source devices in your system, follow these steps to program the correct codes into the remote.

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 is/are potential candidates for the correct code set for your particular device.

2. Turn on your source device.

3. This step places the remote in program mode, and varies slightly, depending on which Input Selector is being programmed. Refer to Figure 36.

a) DVD, Tape, Video 1, Video 2,Video 3 and Video 4 Sources:

Press and hold the Input Selector until the Program Indicator LED starts to flash, then release it. Follow the directions in Step 4, below.

b) CD Source: Press the DVD/CD Input Selector twice quickly so

that it turns green, hold it until the Program LED starts to flash, then release. Follow the directions in Step 4, below.

Step Eight – Program Sources Into the Remote

The AVR 347 remote not only is capable of controlling the receiver, but it may also be programmed to control many brands and models of VCRs, DVD players, CD players, cable boxes, satellite receivers, cassette decks and TVs, as well as an iPod docked in The Bridge.

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

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

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

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

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

AVR347 harman/kardon

INSTALLATION

a) Place the two remotes so that their IR transmitters face each other

end to end, separated by about one inch. See Figure 37. The AVR 347 remote’s transmitter also serves as an IR receiver during the learning process.

Figure 37 – AVR 347 and Original Remote Head-to-Head

Figure 36 – 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; it 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

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 programmed a code, it’s a good idea to try using some other functions to control the device. Sometimes, manufacturers use the same Power code for several different models, while other codes will vary.You may wish to repeat this process until you’ve 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 to enter the Program mode. Then press the Set Button, and the LED will flash in the code sequence. One flash represents “1”, two flashes for “2”, and so forth. A series of many fast flashes represents “0”. Record the codes programmed for each device in Table 3.

b) Press the Input Selector for the device mode you wish to learn a

code into, and place the AVR 347 remote in Learning mode by pressing and holding the Learn Button until the Program Indicator flashes in amber, then release. See Figure 38.

Figure 38 – Learning Remote Commands

c) Press the button on the AVR 347 remote you wish to program with

the new code, and the Program Indicator will light steadily in amber.

d) Press and hold the button on the device’s original remote whose

code you wish to “learn” until the Program Indicator flashes in green, then release it.

e) You may program additional buttons by repeating steps c) and d).

Press the Learn button once to exit Learning mode. If you prefer, you may wait for the remote to “time out” and exit Learning mode on its own, but this will take about 30 seconds.

After you have programmed a code set to operate a device, test the functions to see which ones may be missing or not operating correctly. You may “learn” individual key codes if you have the device’s original remote control by following this procedure:

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 347 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 347. 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’s device mode. See pages 60–61 for instructions on these advanced programming functions.

AVR347 harman/kardon

INSTALLATION

NOTE: The AVR 347 remote is preprogrammed to operate the transport controls of Harman Kardon DVD players when the AVR, the Video 2 (cable/satellite) or the Video 3 (TV) source is selected. You may change this punch-through programming at any time.

Step Nine – Remote IR Inputs and Output (Optional)

The AVR 347 is equipped with a Remote IR Input, a Multiroom IR Input and both full-carrier and stripped Remote IR Outputs to facilitate use of your system with a remote control in a variety of situations. See Figure 39.

Figure 39 – IR Inputs and Outputs

When the AVR 347 is placed in such a way that aiming the remote at the front-panel IR sensor is difficult, such as inside a cabinet or facing away from the listener, you may connect an external IR receiver, such as the optional Harman Kardon HE 1000, to the Remote IR Input jack. When you are using the AVR 347 in multiroom mode, you may connect an optional IR receiver, keypad or other control device to the Multiroom IR Input for remote control of the AVR 347 (and any sources connected to the AVR’s Remote IR Output) from the remote zone. Any signals transmitted through the Multiroom IR Input will only control source selection and volume for the remote zone. If a source device is being shared with the main listening area, then any control commands issued to that source will also affect the main room.

If any of your source devices are equipped with a compatible Remote IR Input, you may use a 1/8" mini-plug interconnect cable (not included) to connect the AVR’s Remote IR Output to the source device’s Remote IR Input, which will pass any applicable remote signals transmitted through the AVR to the source device. This enables you to control your sources even when the AVR itself is controlled via an external IR receiver.

Check with the manufacturer of the source device for more information on the type of IR signal expected. The AVR 347 will output a “stripped carrier” IR signal through the Remote IR Output, but a full-carrier IR signal is available at the Carrier Remote IR Output.

To control more than one source device using the Remote IR Output, connect all sources in “daisy chain” fashion, with the AVR’s Remote IR Output connected to the first device’s Remote IR Input, that device’s Remote IR Output connected to the next device’s Remote IR Input, and so forth. Connect devices expecting a full-carrier IR signal to the Carrier Remote IR Output. Use the Remote IR Output for devices expecting a stripped signal.

IMPORTANT SAFETY NOTE: Installing a multiroom system very often requires running various cables inside walls. Always comply with the appropriate safety codes when installing concealed wiring. The AVR 347’s multiroom connections should be installed per the requirements of all applicable state and local building codes, as well as NEC (National Electrical Code) requirements. Check with your local authorities as needed to ensure that all wiring inside walls is installed in compliance with the proper standards. Failure to do so may present a potential safety hazard. If you have any doubt about your ability to work with electrical and telecommunications wiring, you are advised to hire a professional licensed electrician or custom installer to install the multiroom system.

1. Connect an external amplifier to the Multiroom Audio Outputs. See Figure 40.

Figure 40 – Multiroom Audio Outputs

It is recommended that you place the amplifier in the same room as the AVR 347 so that a shorter length of interconnect cable is used with a long run of speaker wire to the remote room, rather than placing the amplifier in the remote room, which necessitates a long run of interconnect cable that would be subject to signal degradation. Depending on the number of channels available in your amplifier, you may distribute the AVR 347’s analog audio signal to a single pair of speakers for 2-channel listening, to several pairs of speakers located in several different rooms, or when listening to mono FM radio, to individual speakers placed in different rooms. (Use the Tuning Mode Button to select the mono mode for FM radio.)

The advantage of using the Multiroom Audio Outputs is the ability to have a 7.1-channel system in the main listening area at the same time others are listening to a different source in the remote zone. However, the benefit is achieved at the expense of purchasing an additional component, i.e., the amplifier.

2. Connect the remote speakers directly to the Surround Back/ Multiroom Speaker Outputs. See Figure 41.

Step Ten – Install a Multiroom System (Optional)

The AVR 347 offers several methods of distributing music to other listening areas in your home.As indicated in the subheading, installing a multiroom system is not required to enjoy the home theater experience. If you prefer not to install a multiroom system at this time, skip to Step Eleven to turn on the AVR 347 and configure it.

Figure 41 – Surround Back/Multiroom Speaker Outputs

If you do not require a full 7.1-channel system in your main listening area, and you prefer not to purchase an external amplifier to power a pair of remote speakers, you may reassign the AVR 347’s surround back amplifier channels to power the speakers.Your main system will be limited to 5.1 channels, which affects your ability to enjoy the many DVDs and other programs recorded in 6.1 and 7.1 channels.

AVR347 harman/kardon

INSTALLATION

3. Connect an external amplifier to the Surround Back/Multiroom Preamp Outputs. See Figure 42.

Figure 42 – Surround Back/Multiroom Preamp Outputs

This method may be used when it is more important to distribute audio to additional rooms than to have a full 7.1-channel system in the main listening area, as it is still necessary to assign the surround back amplifier channels to the remote zone, limiting the main system to

5.1 channels.This method also requires you to provide an additional component, that is, the amplifier. However, this method may be used to increase the number of remote rooms in the system when you are also using the other options for connecting a multiroom system.

4. Connect an A-BUS hub or other A-BUS components to the A-BUS Port. See Figure 43.

Figure 43 – A-BUS Port

Use Category 5/5e cable as described in the instructions for your A-BUS components.The A-BUS system may carry the audio signal to the remote components, while receiving IR control codes, depending on the capabilities of your A-BUS components. If you connect a hub to the AVR 347, you may distribute audio to many remote rooms.Visit our Web site at www.harmankardon.com for information on our available hubs, the ABH 4 and ABH 4000, and amplified in-wall modules, the AB 1 and AB 2.

Figure 44 – Power Switches

2. There are several ways in which the AVR 347 may be turned on from Standby mode.

a) Press the Standby/On Switch on the front panel. See Figure 44.

b) Press the Source Select Button on the front panel. See Figure 45.

Figure 45 – Source Select Button

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

TAPE/The Bridge, HDMI 1/2, VID1, VID2, VID3, VID4, XM, AM/FM or 6/8CH. See Figure 46.

In addition to the audio signal, you will usually wish to connect an IR control device to the AVR 347’s Multiroom IR Input so that listeners in the remote room may turn the multiroom system on or off, select a source input, control the source device connected to that input and adjust the volume in the remote zone.As mentioned above, an A-BUS system does not require a separate IR control connection.

By using external multichannel amplifiers and A-BUS hubs, it’s possible to construct a system that distributes audio to many rooms throughout your home.

NOTE: Only analog audio sources are available to the multiroom system.

Step Eleven – Turn On the AVR 347

Two steps are required the first time you turn on the AVR 347.

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 44. Normally, you may leave the Master Power Switch in the ON position, even when the receiver is not being used.

Figure 46 – AVR and Input Selectors

NOTE: Any time you press one of the Input Selectors on the remote (i.e., DVD/CD, TAPE/The Bridge, HDMI 1/HDMI 2, VID1, VID2, VID3 or VID4), the remote will switch modes so that it will only transmit the codes programmed to operate that device. In order to control the receiver, press the AVR button to return the remote to AVR mode.

AVR347 harman/kardon

INITIAL SETUP

Before you begin enjoying your new receiver, a few adjustments should be made to configure the AVR 347 to match your actual system.

Make sure that you have connected a video display to one of the

video monitor outputs on the receiver. When you turn on your display and the AVR, you should see a blue screen. A message may appear briefly at the bottom of the screen. This message is part of the on-screen display system, and is referred to as the “semi-OSD”. The semi-OSD is activated any time you send a command to the AVR, and any time the AVR detects a change in the incoming signal. Semi-OSD messages are overlaid on top of any video signal, so that you may continue to watch your program while making adjustments to the AVR.

Although it’s possible to configure the AVR using only the remote and the semi-OSD messages, we recommend that you use the full-screen menu system, known as the “full OSD”.

Using the On-Screen Menu System

The full-OSD system is accessed by pressing the OSD Button on the remote. See Figure 47. While the full-OSD system is in use, it isn’t possible to see any video programming. In addition, an OSD ON message will appear on the front panel of the receiver to remind you to use a video display.

Figure 48 – OSD System

When you first select a menu, the first setting line will be highlighted (see Figure 49).

Figure 49 – Input Setup Menu

If you wish to change that setting, press the Set Button. Although the setting name will remain highlighted, the value will appear in blue type with arrows to the left and right, indicating that you may use the

‹/›

Buttons to scroll through the available values. See Figure 50. When the desired value appears, press the Set Button to select it.

Figure 47 – Navigation Buttons

NOTE: The ‹/› and Set Buttons on the front panel have no effect on the OSD system.

The OSD system consists of six main menus: Input Setup, Surround Setup, Speaker Setup, Multiroom Setup, Video Setup and System Setup. Navigation tabs for each menu appear on the left side of the screen. When you first press the OSD Button, the Input Setup menu will be visible (see Figure 48), since its tab is at the top of the screen. However, you must press the Set Button to select the Input Setup menu so that you can make any necessary adjustments. If you wish to select another

⁄/¤

menu, use the

Buttons to highlight the tab for the desired menu,

and press the Set Button to select it.

Use the ⁄/¤Buttons to navigate to other settings within the menu. When you have finished making all adjustments in that menu, press the

‹ Button to return to the navigation tabs, and then use the

⁄/¤

Buttons to select the tab for another menu.

We recommend that most users follow the instructions in this INITIAL SETUP section to configure a basic home theater system. You may return to these menus at any time to make additional adjustments. Thanks to the EzSet/EQ system, most of the menu adjustments may be saved until you have become more familiar with the AVR, and are therefore described in the Advanced Functions section.

AVR347 harman/kardon

INITIAL SETUP

The Initial Setup section requires that you complete all of the steps in the Installation section that apply to your receiver. You should have connected all of your loudspeakers and a video display, as well as your source devices.You should be able to turn on the receiver and view a blue screen on Section before continuing.

Configure the AVR 347 Using EzSet/EQ

One of the most important and perhaps often overlooked aspects of setting up a home theater system is to calibrate the receiver to match the loudspeakers, which enables the AVR to perform at its best.

Until recently, most receivers required the user to perform the calibration and configuration manually, a somewhat tedious process that called for a good ear or the purchase of an SPL (sound-pressure level) meter. Although you may configure the AVR 347 manually, as described in the Advanced Features section, we recommend that most users take advantage of our signature EzSet/EQ system.

your video display. If necessary, reread the Installation

Figure 52 – Speaker Setup Menu Screen

Select the “Auto Configuration” setting, and the screen shown in Figure 53 will appear to direct you to plug the EzSet/EQ microphone into the Headphone Jack.

Before beginning, eliminate extraneous background noise that might affect the results, such as noisy air conditioning. Try to avoid making any loud noises while running EzSet/EQ.

IMPORTANT SAFETY NOTE: During the EzSet/EQ procedure, a series of very loud test tones will be played through all of the speakers.Avoid sitting or standing close to any one speaker during the procedure. If you are particularly sensitive to loud noises, you may wish to leave the room and have someone else run EzSet/EQ.

Step One – Place the included EzSet/EQ microphone in the listening position, or in the center of the room, at about the same height as the listeners’ ears.The microphone features a threaded insert on the bottom so that it can be mounted on a camera tripod for stability. An extender rod is also included.

Step Two – Plug the EzSet/EQ microphone into the Headphone Jack/EzSet Microphone Input Jack on the front of the receiver. See Figure 51.

Figure 53 – EzSet/EQ Screen

Step Four – After you select “Continue”, the screen shown in Figure 54 will appear. Although the AVR 347 may be used with up to eight speakers, you may have elected not to install surround back speakers at this time, or you may have decided to use the surround back speaker channels to power speakers in the remote room of a multiroom system. This screen directs you to program EzSet/EQ for a 5.1- or 7.1-channel configuration. Select the setting that reflects the number of speakers installed in your system, and EzSet/EQ will do the rest automatically!

Figure 51 – Plug EzSet/EQ microphone into receiver.

Step Three – Make sure that the AVR 347 and the video display are turned on. Press the OSD Button to display the Menu System. See

⁄/¤

Figure 48. Use the

Buttons to move the cursor to the Speaker Setup tab, and then press the Set Button to select the Speaker Setup menu. See Figure 52.

Figure 54 – EzSet/EQ: Number of Speakers

NOTE: If you are using fewer than five main speakers in your system, then it will not be possible to configure your speakers using EzSet/EQ, and you will need to select Manual Configuration as described in the Advanced Functions section. If you have selected a 6.1-channel configuration, using only a single surround back speaker, it is possible to use a combination of EzSet/EQ automatic configuration for 5.1 speakers, connect the single

AVR347 harman/kardon

INITIAL SETUP

surround back speaker to the left Surround Back Speaker Output, and then configure the surround back speaker manually, as described in the Advanced Functions section. However, we do not recommend the 6.1-channel configuration.

If you have forgotten to plug in the EzSet/EQ microphone, the warning screen shown in Figure 55 will appear as a reminder.

Figure 56 – EzSet/EQ: Speaker Level Test

If at any time the test tone is not heard from the speaker indicated on screen, press the Set Button to stop EzSet/EQ. Turn off the AVR using the Master Power Switch and check your speaker connections. Make sure all wires are connected to the correct speakers and Speaker Outputs on the AVR, and that you have observed the correct polarity (+ terminals connected to + terminals, and – terminals connected to

Figure 55 – EzSet/EQ: Warning to Plug in Microphone

– terminals).

NOTE: As shown in Figures 53, 54 and 56–59, while EzSet/EQ is in progress a Cancel setting is highlighted. You may interrupt EzSet/EQ at any time by simply pressing the Set Button.

What EzSet/EQ Does

EzSet/EQ will send test signals to the various speakers and perform the measurements described in this section, adjusting the AVR 347’s settings to match EzSet/EQ’s internal references.

Set Master Volume Level: EzSet/EQ sends test tones to the front speakers and adjusts the system’s volume level to enable it to take the remaining measurements correctly. EzSet/EQ uses the left front speaker to set the master volume level, and then it proceeds directly to measuring the speaker output levels.

Speaker Level: During this test, EzSet/EQ ensures that all speakers sound equally loud at the listening position. During a surround sound presentation it is common for the surround channels to sound less prominent, or not to be used at all at times. By setting the baseline channel levels correctly, the AVR behaves as a blank canvas for the movie director to create special effects.

A screen similar to the one shown in Figure 56 will appear, with the speaker position changing as EzSet/EQ measures the levels for each speaker. You may occasionally hear EzSet/EQ send a tone back to the front left speaker. This enables EzSet/EQ to compare the level of the speaker being measured to the reference level it set for the front left speaker.

NOTE: EzSet/EQ can detect only the presence of a speaker, not its location within the room. If your speakers are not placed reasonably close to the positions shown in the Speaker Placement Section on page 23, EzSet/EQ may not be able to perform this test correctly.

If EzSet/EQ detects only one speaker in a pair (e.g., surround back left but no surround back right or no main speakers), it will generate an error and stop. If that happens, check that you have placed your speakers in their correct locations, and that you have wired each speaker to its correct set of speaker terminals.

Speaker Distance: During this test, EzSet/EQ measures the distance from each speaker to the listening position. If the speakers are placed at different distances from the listener, the sound from speakers placed closer needs to be delayed so that it reaches the listener at the same time as the sounds from the other speakers.This preserves the clarity and directionality of surround sound presentations. During the Speaker Distance test a screen similar to the one shown in Figure 57 will appear. The speaker position will change as EzSet/EQ measures the distance for each speaker.

NOTE: The AVR 347 is also capable of setting a different type of delay, called A/V Sync Delay. A/V Sync Delay is used to compensate for lip sync problems that may occur when a video

INITIAL SETUP

display device or set-top box causes delays while digital video signals are processed. It simultaneously adds a delay to all speaker channels in the system. A/V Sync Delay is not set during EzSet/EQ. It may be set while watching a program as follows: press the Delay Button on the remote and the first setting displayed is A/V Sync Delay. Press the Set Button to select it and then use the

⁄/¤ Buttons to adjust it.

Speaker Size: This test checks the low-frequency range capabilities of each of your speakers to ensure that low-frequency sounds are not sent to speakers unable to reproduce them efficiently. Each of the main speakers in your system will be assigned a value of Large or Small, depending solely on how it handles low frequencies. During the Speaker Size test a screen similar to the one shown in Figure 58 will appear, with the speaker position changing as each speaker is measured.

is making these adjustments a screen similar to the one shown in Figure 59 will appear. You may hear EzSet/EQ repeat tones from various speakers a number of times as it performs the equalization.

When EzSet/EQ has finished running all of these tests, a screen similar to the one in Figure 60 will appear. You may press the Set Button, and the Speaker Setup screen shown in Figure 52 will appear. Select “Manual Configuration” to view the settings resulting from EzSet/EQ. The manual Speaker Setup screens are explained in the Advanced Functions section.

Figure 58 – EzSet/EQ: Speaker Size/Crossover Test

At the same time the overall size of the speaker’s frequency range is measured, the AVR will measure the crossover, which is the lowest frequency each of your main speakers is capable of handling effectively, in order to set the highest frequency the subwoofer should reproduce. The system balances the need to ensure that all frequencies are reproduced for smooth transitions between the subwoofer and main speakers without losing any information, against the need to avoid overtaxing smaller satellite speakers.

NOTE: The crossover determined by EzSet/EQ is not the same as the crossover frequency specification that appears in the speaker’s manual. EzSet/EQ is measuring the point at which the audio signal must be passed from the main speaker to the subwoofer. For an individual loudspeaker, the manufacturer specifies the point or points at which the audio signal is passed from one transducer within the speaker to another.

Equalization (EQ): Many factors unique to the listening room can affect the overall sound of a home theater system. For example, a room consisting of hardwood floors and large expanses of glass can sound livelier, with added reverberation, while a carpeted room fitted with draperies can dampen sound waves. In addition, the shape of the room can affect frequency response. If a room has a small alcove near a doorway, for example, you may notice a difference in bass response depending on whether you are standing opposite the alcove or to one side of it.

Configure Sources

In the Installation section, you physically connected various cables between your source devices and the AVR. In this section, you will assign the various audio and video inputs to their sources, ensuring that the AVR uses the correct connections each time you select a source.

Press the OSD Button to view the menu system. The Input Setup menu tab will be highlighted. Press the Set Button to select it, and the screen shown in Figure 61 will appear.

EzSet/EQ is capable of measuring the impact room characteristics and speaker placement have on each speaker’s performance, and of making adjustments to low-frequency response to compensate.While EzSet/EQ
