AVR225

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.

harman/kardon

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.

14 INSTALLATION AND CONNECTIONS

System Installation

After unpacking the unit, and placing it on a solid surface capable of supporting its weight, you will need to make the connections to your audio and video equipment.

Audio Equipment Connections

We recommend that you use high-quality interconnect cables when making connections to source equipment and recorders to preserve the integrity of the signals.

When making connections to audio source equipment or speakers it is always a good practice to unplug the unit from the AC wall outlet. This prevents any possibility of accidentally sending audio or transient signals to the speakers that may damage them.

1. Connect the analog output of a CD player to the

CD Inputs £.

NOTE: When the CD player has both fixed and vari-

able audio outputs it is best to use the fixed output unless you find that the input to the receiver is so low that the sound is noisy, or so high that the signal is distorted.

2. Connect the analog Play/Out jacks of a cassette deck, MD, CD-R or other audio recorder to the Tap e Input Jacks ∞. Connect the analog Record/In jacks on the recorder to the Tape Output Jacks ¢ on the AVR 225.

3. Connect the output of any digital sources to the appropriate input connections on the AVR 225 rear panel. The Optical and Coaxial Digital Inputs

#$ may be used with a Dolby Digital or

DTS source such as a DVD player, or the output of a conventional CD or LD player’s PCM (S/P-DIF) output.

4. Connect the Optical Digital Audio Output ‡ or the Coaxial Digital Audio Output ° on the rear panel of the AVR 225 to the matching digital input connections on a CD-R or MiniDisc recorder.

5. Assemble the AM Loop Antenna supplied with the unit as shown below. Connect it to the AM and GND Screw Terminals ¡.

6. Connect the supplied FM antenna to the FM Antenna (75-Ohm) Connection ™. The FM anten- na may be an external roof antenna, an inside powered or wire lead antenna or a connection from a

cable TV system. Note that if the antenna or connection uses 300-ohm twin-lead cable, you must use the 300-ohm-to-75-ohm adapter supplied with the unit to make the connection.

7. If you have a DVD-Audio or SACD player, or other component that includes an onboard surround decoder and 6-channel line-level audio outputs, you may connect these audio outputs to the 6-Channel

Direct Inputs i.

8. Connect the front, center and surround Speaker Outputs ª‚⁄¤‹ to the respective speakers.

To ensure that all the audio signals are carried to your speakers without loss of clarity or resolution, we suggest that you use high-quality speaker cable. Many brands of cable are available and the choice of cable may be influenced by the distance between your speakers and the receiver, the type of speakers you use, personal preferences and other factors.Your dealer or installer is a valuable resource to consult in selecting the proper cable.

Regardless of the brand of cable selected, we recommend that you use a cable constructed of fine, multistrand copper with a gauge of 14 or smaller. Remember that in specifying cable, the lower the number, the thicker the cable.

Cable with a gauge of 16 may be used for short runs of less than 10 feet. We do not recommend that you use cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur.

Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other appropriate testing agency standards. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area.

When connecting wires to the speakers, be certain to observe proper polarity. Remember to connect the “negative” or “black” wire to the same terminal on both the receiver and the speaker. The AVR 225 conforms to the latest CEA-recommended color-coding for speaker terminals. Accordingly, the positive (+) terminal, which was previously red, is now a specific color to assist you in making the correct connections. If your speakers have color-coded connections, match the terminal on the AVR 225 to the like terminal on your speakers. For existing speakers with a red terminal for the positive connection, the connections on the AVR 225 are as follows:

Front Left = White Front Right = Red Center = Green Surround Left = Blue Surround Right = Gray

NOTE: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this configuration. To ensure proper phase and optimal performance, consult the identification plate on your speaker or the speaker’s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer for advice before proceeding, or consult the speaker’s manufacturer.

We also recommend that the length of cable used to connect speaker pairs be identical. For example, use the same length piece of cable to connect the front-left and front-right or surround-left and surround-right speakers, even if the speakers are a different distance from the AVR 225.

9. Connections to a subwoofer are normally made via a line-level audio connection from the Subwoofer Output • to the line-level input of a subwoofer with a built-in amplifier. When a passive subwoofer is used, the connection first goes to a power amplifier, which will be connected to one or more subwoofer speakers. If you are using a powered subwoofer that does not have line-level input connections, follow the instructions furnished with the speaker for connection information.

Video Equipment Connections

Video equipment is connected in the same manner as audio components.Again, the use of high-quality interconnect cables is recommended to preserve signal quality.

Although any compatible video device may be connected to any video input (with the exception of the

Video 1 and Video 2 Out Jacks dg

, which may only be connected to a video

recorder), to make programming device codes into the remote control easier, we recommend that you connect your VCR to the Video 1 Connectors cd

, your television to the Video 2 Input Connectors f , and your cable-TV converter or satellite receiver to the Video 3 Input Connectors h .

1. Connect a VCR’s or other video source’s audio and video Play/Out jacks to the Video 1 or Video 2 In Jacks cf on the rear panel. The Audio and

Video Record/In jacks on the VCR should be

connected

to the Video 1 or Video 2 Out Jacks

dg on the AVR 225.

INSTALLATION AND CONNECTIONS

2. Connect the analog audio and video outputs of a television set or any other video source to the Video 2 Input Jacks f .

3. Connect the analog audio and video outputs of a cable TV converter or satellite receiver, or any other video source, to the Video 3 Jacks h .

4. Connect the analog audio and video outputs of a DVD or laser disc player to the DVD Jacks a k . When a digital audio connection is used for your DVD player, the default connection is the Coaxial Digital Audio Input 1 Jack b.However, the connection may also be made to any of the Optical e # or Coaxial b $ digital audio inputs, provided that the digital input source selection is changed as shown on pages 17 and 26. If your DVD or DVD-Audio player includes an onboard surround decoder and 6-channel line-level audio outputs, you may connect these audio outputs to the 6-Channel Direct Inputs i. When you wish to hear this decoded audio, select the DVD input first in order to select the video signal from the DVD player, then select the 6-Channel Direct Input source for the audio.

5. Connect the digital audio outputs of a DVD player, satellite receiver, cable box or HDTV converter to the appropriate Optical or Coaxial Digital Audio Inputs

#$.

6. Connect the Video Monitor Output ·j jacks on the receiver to the composite or S-Video input of your television monitor or video projector.

VIDEO CONNECTION NOTE:

• Composite and S-Video signals may only be viewed in their native formats. The AVR 225 will not convert signals from composite to S-Video, or vice versa. S-Video inputs may only be viewed when the AVR 225 is connected to a TV set or video display with S-Video capability. If you use both standard composite video and S-Video sources in your system, it is important that you connect both an S-Video cable and a standard composite video cable (a coax cable with an RCA plug on both ends) between the AVR 225 and your TV or projector. When it is necessary to make both types of connections to your TV set, use different inputs if possible. Consult the instructions for your TV set or projector for more information on connecting both types of signals.

Power Connections

This unit is equipped with two accessory AC outlets. They may be used to power accessory devices, but they should not be used with high-current draw equipment such as power amplifiers.The total power draw to each outlet may not exceed 100 watts.

The Switched AC Accessory Outlet › will receive power only when the unit is on. This is recommended for devices that have no power switch or a mechanical power switch that may be left in the “ON” position.

NOTE: Many audio and video products go into a Standby mode when they are used with switched outlets, and cannot be fully turned on using the outlet alone without a remote control command.

The Unswitched AC Accessory Outlet ﬁ will receive power as long as the unit is plugged into a powered AC outlet.

Finally, when all connections are complete, plug the Power Cord ﬂ into a nonswitched 120-volt AC wall outlet. You’re almost ready to enjoy the AVR 225!
