Signature 2.0 Processor/Tuner 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.

Signature 2.0 Processor/Tuner harman/kardon

Before returning the unit to the user, perform the following safety checks :

1. Inspect all lead dress to make certain that

leads are not pinched or that hardware is not

lodged between the chassis and other metal

parts in the unit.

2. Be sure that any protective devices such as

nonmetallic control knobs, insulating fish-

papers, cabinet backs, adjustment and

compartment covers or shields, isolation

resistor-capacity networks, mechanical

insulators, etc. Which were removed for the

servicing are properly re-installed.

3. Be sure that no shock hazard exists ; check for leakage

current usingSimpson Model 229 Leakage Tester, standard

equipment item No. 21641, RCA Model WT540A or use

alternate method as follows : Plug the power cord directly

Into a 120 volt AC receptacle (do not use an Isolation

Transformer for this test). Using two clip leads, connect a

1500 ohms,10watt Resistor paralleledby a 0.15uFcapacitor,in series withall exposed metal cabinetparts and aknown earth ground,such

as a water pipe or conduit. Use a VTVM or VOM with 1000 ohms per volt, or higher sensitivity to measure the AC voltage drop across the

resistor. (See diagram) Move the resistor connection to each exposed metal part having a return path to the chassis (antenna, metal,

cabinet, screwheads, knobsand controlshafts, escutcheon, etc.) and measure the ACvoltage dropacross theresistor.(This test should be

performed withthe 0.35 volt RMS or more is excessive and indicates a potential shock hazardwhich must becorrected before returningthe

unit to the owner.

1. Before proceeding, make certain that all equipment, including the 2.0, is unplugged from AC power. This will prevent any damage due to the unintended activation of automatic turn-on circuits.

2. Use high-quality audio and video interconnect cables to connect your source equipment to the rear of the 2.0 as shown in the diagram above and the table below. It is important to note that unlike conventional audio/video equipment, the 2.0 does not have inputs that are labeled for connection to a specific type of equipment (e.g., inputs labeled “CD,” “Tape” or “VCR”). Instead, the 2.0 allows you to connect the analog or digital audio and composite or S-Video outputs of your source equipment to any of the inputs. Then, using the setup procedures detailed on page 28 of this manual, you can custom configure the input sources. However, for a quick starting point, follow the input suggestions outlined in the chart shown below. They conform to the preset conditions for the 2.0.

At this point you are “on the air”! Sit back and enjoy the best in home entertainment.

Operating Hints

The following hints will help you to enjoy the sonic power and operating flexibility of the Signature Series

2.0 while you become accustomed to the way it works. Depending on the type of equipment in use in your system, it may, or may not be necessary to follow these hints:

•

If you change the Speaker Setup, keep in mind that the changes apply to all modes. You may not change the Speaker Setup for one mode, and not another.

•

When the front channel speakers are set to the LARGE mode, the subwoofer output will only be active when a Dolby* Digital source with Low-Frequency Effects (LFE) or DTS are in use. In order to have a full-time output from the subwoofer channel, the front speakers must be set to SMALL. (This is the factory preset configuration.)

•

If the Surround Mode indication flashes in the front panel display, that is an indication that the input source is not compatible with the desired mode. The flashing mode is not the one originally selected, rather, it is the

mode automatically selected by the 2.0 to match the input source. For example, when the Pro Logic* mode is selected, but a Dolby Digital source is playing, the

2.0 will automatically select Dolby Digital, but the mode will flash to remind you that while it is correct, it is not the mode originally selected.

•

Note that when a DVD is in use, the digital audio output is interrupted when the player is in the pause, fast search, slow speed or reverse modes. Since the 2.0 does not receive a digital signal in these cases, it will momentarily try the Pro Logic mode as an alternate. This temporary mode change does not indicate any fault or problem with the 2.0, and the unit will return to the Dolby Digital or DTS Mode shortly after the DVD is put back into a standard play mode.

•

If one input source requires a significantly higher volume level than others, or when there is a distinct increase in the noise level or distortion with one input in comparison to others, this is a sign that the input level needs to be adjusted. See pages 29–30 of this manual for instructions on adjusting the input level.

•

When certain DVD players are used, it is normal to hear an occasional click or pop noise when the DVD player is put back into play after being paused, or when some DVD discs change chapters. This is a normal side effect of the way in which some DVD players and digital decoders work, and it does NOT indicate a problem with the 2.0 or with your DVD player.

Of course, this is only the tip of the iceberg. Although you have successfully completed a minimal installation we strongly recommend that you take time to read this manual thoroughly. It will show you how to use the many features, modes and controls that are a vital part of the Signature 2.0. Correct setup and installation is important to optimizing the sound quality of your new controller, and will also make it easier to operate. A few minutes spent reading the manual and making certain that your new 2.0 is set up to meet the individual characteristics of your system and listening room will enable the 2.0 to deliver all the performance it is capable of.

Troubleshooting Guide

Signature 2.0

Troubleshooting Guide

The Signature 2.0 is designed for trouble-free operation. In normal use, most users will not encounter any trouble with the unit. However, as with any sophisticated electronic device, there may be occasional problems on initial installation or during the life of the unit. The items described on this page and in the table below are a brief guide to the minor problems that you may be able to correct yourself, and to certain anomalies that result from outside conditions.

If these solutions do not rectify a problem, or if the problem persists, contact your dealer or installer. Problems may also be solved by an authorized Harman Kardon Service Center. To locate the Service Center nearest you, call (800) 422-8027 toll free in the United States. Harman Kardon may be contacted via the Internet at www.harmankardon.com

Error Messages

When the surround mode name blinks in the front panel

Information Display

(Figure FPD-12) that is your indication that there is a mismatch between the input source and the surround mode, or that there is no digital input at all.

Mode Mismatch

Certain modes are digital only, while others operate with analog signals only. The blinking light is an indication of a source/mode mismatch.

When this condition exists, the 2.0 will automatically select a properly matched surround mode and continue normal operation. To view the name of the mode selected, press the

Display

button x. The correct

mode will be displayed next to the

Alt Mode

indication (Figure OSD-27). To stop the flashing message, press the appropriate

Surround Mode

Selector y 4

until the correct mode is selected.

No Data

If the mode name flashes when the mode and input are matched, this is an indication that the 2.0 is not receiving digital data from the source machine. This will typically occur when a DVD player is in pause or a fast scan

mode, as no digital data is typically output unless the disc is playing. To confirm that the lack of data is the cause of the error message, press the

Display

button

and check the on-screen status screen. If a

AC-3 Info

message appears (Figures OSD-14/ OSD-18/OSD-27), this is your indication that the player is not sending a digital signal. Put the unit into Play, check the digital input connections or check to see that a digital input is selected to solve this problem.

Digital Noise With DVD Players

Certain early models of DVD players may occasionally cause a sharp “crack” or “snap” in the output channels during track or chapter changes. This is caused by a momentary discontinuity in the digital data output which is not long enough to trigger the flashing error message, but long enough to disrupt the processor. This type of random noise is caused by the DVD player, and it does not indicate a problem with the 2.0.

System Reset

In rare cases where the 2.0’s operation or the displays seem abnormal, the cause may be erratic operation of the system’s memory or microprocessor.

The first step to correct this problem is to turn the 2.0 off using the

Master Power Switch1

and unplug the unit from the AC wall outlet and wait at least three minutes. After the pause, reconnect the AC power cord and turn the unit on again. If the system still malfunctions, a system reset may clear the problem.

Note that clearing the system memory may correct the problem, but will also erase all system configuration data, input source assignments, input profile names, effects level settings and tuner preset memories. It is always a good idea to record your system configuration information in the Worksheets in Appendix B, if possible, before resetting the system. To reset the system, press the

Software (IC U305) Replacement Instructions

Before replacing the software in the SIGNATURE 2.0 Processor, confirm the Software revision in the unit. To check, plug the unit in and turn it ON. The display will read “Ver __.__”. Make sure the version you are replacing is a higher number than what’s on the display.

CAUTION: IC U305 EPROM IS AN ELECTROSTATICALLY SENSITIVE DEVICE AND CAN BE DAMAGED BY CARELESS HANDLING; YOU MUST FOLLOW PROPER STATIC CONTROL PROCEDURES TO PREVENT DAMAGE TO THE DEVICE.

1. Confirm the unit is unplugged and OFF.

2. Remove the 7 top cover screws. There are 2 on each side and 3 on the upper portion of the back panel.

3. Remove the top cover; slide it towards the back of the unit about an inch and lift it off from the back first.

4. Locate the video board directly behind the video jacks. Unplug the ribbon cable marked “CONTROL” on the circuit board under the ribbon. Unplug the green power supply cable marked “PWR”; apply only upward force to remove it.

5. Locate and remove the (4) screws and (1) nut holding the video board on. Two screws are located between the “COMPOSITE VIDEO” RCA jacks on the back panel. Two screws, with washers, are located on either lower side of the “S VIDEO” jacks on the back panel. The (1) nut is located on the inside corner of the printed circuit board next to capacitor C504.

6. Remove the video board by lifting the edge of the circuit board that has the connectors on it (CONTROL and PWR) up and out of the way of the power supply capacitors before complete removal.

7. The software IC (U305) should be visible at this point. Find it on the CPU circuit board under the video board, plugged into a 32 pin IC socket marked U305. You may need to move the 10 conductor ribbon cable aside to read the locator number; there is also a label on the IC stating the software version. (On one side of the IC there is a ribbon connector, on the other side of the IC is another device - MS6264L).

8. Apply a “L” shaped pick or jewelers flat blade screwdriver between the IC (U305) and socket at the notched end. Pry the end of the IC up enough to grab it and carefully lift straight up without further bending the pins while you complete the extraction.

9. Test fit the new IC (h/k part# A003-0020-4). The legs usually need to be bent inward. Do this by placing one side of the IC legs against the edge of a table to bend all of them at the same time. Do this on both sides just enough for the IC to fit properly into the socket.

10. Position the IC so the notch faces towards the transformers. Line up the legs into the socket and press down hard enough to seat the IC into the socket. Look at the legs on both sides of the IC and make sure there are not bent or misaligned.

11. Reinstall the video board in the same manner it was removed as in step 5, and reinstall the screws in their respective locations.

12. Plug the ribbon cable into the connector marked “CONTROL” and the green power cable into the connector marked “PW R”.

13. Replace the top cover in the same manner it was removed in step 2, and reinstall the 7 screws. Tighten the rear panel screws first.

14. You must do a reset for the new software to be enabled. Make sure the On/Off button is in the OFF position . Plug the unit into an AC ou tlet. While pressing the SOURCE and MUTE buttons down at the same time, turn the On/Off button to the ON position. At this moment, the lower line of the display must read “Initialized”. You may then release the buttons.

The following code changes were made from ver 2.5E to create 2.6 of th e Signature 2.0.

1. Added menu entry in “Source Menu” for Video Detect. This allows the user to configure each individual source to switch to a Blue Screen when a loss of video sync pulses is detected, as in the default or “Auto” mode, or disable the detection altogether in the “Off” mode. The “Off” mode is useful when a video source is used that may exhibit video sync pulses that may be too weak for the Signature video board to deal with correctly, causing the Blue screen to appear rather than the selected video.

Page 39

Signature 2.0 Processor/Tuner harman/kardon

2. When cycling through the “Mode” line of the “Source Menu” the DSP (new Crystal model ONLY) would remain muted, thereby causing no output. This has now been fixed.

3. When a digital inpu t stream is Auto- detect ed as a DTS s tream, the default mode set is now full 3/2 rather than 2/0.

4. With the Tuner selected, if a numeric input sequence is left unfinished, the OSD will no be correctly updated with the current Tuner information.

5. When s electing a station via numeric input from the remote, the OS D display is now correctly updated when the Tuner becomes tuned.

6. From the “Tuner” menu, when RDS: entry is set to Manual and a Preset is then stored, the screen and system are then correctly stored and updated on the OSD. The lack of OSD update would create confusion as to whether the preset had actually been accomplished.

7. From the Tuner menu with any mode except “Stereo” se lected, if the user presses the >| button on the “FREQ:” line to search for the next station, the Tune r will no longer stay muted. I believe this problem would only show up with the Crystal DSP board.

The following code changes were made from ver 2.6 to create 2.7 of the Signature

2.0.

1. Fixed problem that prohibited generation of pink noise in speaker calibration menu if a valid stream was present on a selected digital input.

2. Changed code to ensure that all unused output channels we re muted when in Stereo mode.

3. Fixed screen timeout problem that caused an “unfinished” numeric input to remain on the OSD when attempting to change the tuner frequency with the Tuner selected.

The following code changes were made from ver 2.7 to create 2.8 of the Signature

2.0.

1. With a Dolby Digital 2/0/0 stream present, if the Stereo button on the remote is pressed, the 2.0 will go into Pro Logic mode. This is require d by Dolb y to fix the ir problem of some incorrectly flagged program material.

2. Trim control ranges are now limited to +10 –20 dB.

3. A ll channels will now track the master volume in level. This will compensate for trimmed channels and the non-linearity of the volume pots

4. Balance control now works correctly.
