INSTALLATION & SETUP
Setting the Crossover [s]
  • Determine your system plans and set the crossover mode switch accordingly. If you plan to use the GTO75.2 or GTO75.4 to drive full-range speakers, set the crossover mode to FLAT and skip to “Setting Input Sensitivity.”
  • Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible.
  • Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. Adjust the crossover frequency to limit bass and provide increased system volume with less distortion.
  • For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer.
  • If using the GTO75.2 or GTO75.4 to drive a subwoofer(s), set the crossover mode to LP (low pass).
NOTE: The GTO301.1, GTO601.1, GTO1201.1 and the subwoofer output of the GTO755.6 are low-pass only and do not have a crossover mode switch.
SETTING INPUT SENSITIVITY
  • Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise).
  • Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track.
  • On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT LEVEL slightly until distortion is no longer heard.
NOTE: After the source unit is on, red LEDs (on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit.
REMOTE LEVEL CONTROL
  • The GTO755.6 and all three GTO subwoofer amplifiers have inputs for an optional remote level control (RLC). This will allow the amplifier’s input level to be adjusted from the listening position. Connect the optional remote level control using the RJ-11 jack on the side of the amplifier.  Install the control module in the front of the vehicle within easy reach of the driver.  Under the dash or in the center console are both suitable locations.
THE BASS BOOST SETTING
  • The GTO755.6, GTO301.1, GTO601.1 and GTO1201.1 are all equipped with a bass-boost control. This allows you to adjust the bass output of your system at 50Hz up to 12dB and enhance low frequency.
AUX OUTPUT
  • GTO amplifiers (except GTO755.6) are equipped with full-range outputs that can be used to connect additional amplifiers. NOTE: When using the high-level inputs, the AUX outputs can be used to pass a line-level signal to another amplifier.
Control end panel                      {Click on images to Magnify}

INSTALLING NEON TUBES
  1. Using a Phillips screwdriver, remove all screws on the amplifier’s output/power end panel and set them aside.
  2. Using a 3 ⁄ 32-inch Allen wrench, remove only the screws on the amplifier’s (top) clear cover and set them aside.
  3. Remove the end panel and slide the cover off. Set both parts aside.
  4. Locate the enclosed hardware bag and remove the four clips. Each clip has a square end and a larger round end.  Using a round end, press two clips onto each neon tube (e.g., Street Glow AN9 or equivalent).
  5. For each tube, align both clips so the square ends slide onto an exposed extrusion edge.  Do not cover any screw holes. When installed correctly, each neon tube will sit under an extrusion and not be visible when viewed from directly above.
  6. Route each neon tube’s power cable through its respective NEON hole on the end panel.
  7. Slide the cover back into place and re-install its screws. Then, replace the end panel and reinstall its screws.
  8. Finish the installation of the neon tubes as instructed in their owner’s manual.

 Set came for repair in dead condition.  No standby light, no audio thumb sound at switch ON.  Seemed fully dead.  Transistors are used in SMPS supply circuit.

  Checked all the transistors, 3 of them, at the power supply circuit.  De-soldered them out from circuit, and checked.  All of them was OK.  Checked all the four rectifier diodes.  Found OK. 

  If so, the power supply must turn ON.  The standby light at the front panel should light up.  Here it is not.  Suspected the horizontal output, and horizontal drive circuit.  Checked the horizontal output transistor (BU508DF) in circuit.  Found as OK.  Checked the continuity of the primary and secondary windings of driver transformer.  Found OK.  Then what should be the fault.  It is sure that, there must be some short circuit at the secondary side of the SMPS power transformer.  
Checked all the rectifier diodes and capacitors connected in parallel across them.  All were OK.

  Disconnected the Line output transformer {LOT} bower supply, by disconnecting one end of the resistor [2.2Ohms] here, and switched ON the set. 
Front panel power LED began to light up.  Checked the voltage at all secondary outputs of SMPS transformer and all other low voltages fed from it to different other section circuits.  According to circuit diagram, all was found OK.  Replaced the Horizontal Output Transistor with a new one.  Set worked all right.  Checked all other functions. 

Checked the horizontal output transistor, which was taken out from the circuit, using a digital multimeter.  Found that, its Base to Emitter resistance measured very low, in Ohms [Approximately 2Ohms].  It is clear that, the BàE junction inside it is leaky (A rare fault).
Conclusion;  Here the SMPS power supply have over load protection.  Even though it is not an opto-coupler coupled regulator, it will sense any short circuit at the secondary side of the SMPS transformer. Never go so much as I’ve done here.  The fault is with the Horizontal Output Transistor (BU508DF) itself.  The kit found with this set is common to most of the BPL models, including 21” CTVs.

See the internal configuration of BU508DF

Appearance
The similar fault will be occur to most of the Chinese kit, available in local market too.

DISPLAY MODE FOR NUMBERS OF PROTECTION DETECTION
The numbers of detection for various protection processes are displayed.
TO ENTER & EXIT
  • During Standby mode, simultaneously press and hold the [PRESET –] and [STANDBY/ON] keys for 2 seconds to enter this mode.
  • The display will return to the normal indication when no key operation is performed for 5 seconds.
BASIC OPERATIONS
#1 "5 (-> normal)" denotes that the display will return to the normal indication when no key operation is performed  for 5 seconds.
#2 Variable range: 0 to 255.
  • The above-mentioned Display mode is available only when the product operates properly.
  • If any protection function is activated while the product is in use, the product cannot be turned ON and enter the above Display mode. In such a case, cancel the protection function, referring to “3.4 How to cancel the status after detection of the DC error." If a protection function is activated immediately after the previous protection function is canceled, cancel that protection function again then enter STBY mode immediately. You can then see the error logs, following the above procedures, until a next protection function is activated.
RESET MODE FOR NUMBERS OF PROTECTION DETECTION
For clearing all the counts of protection detections. (This mode resets the counts of protection detections.)
TO ENTER & EXIT
  • During Standby mode, simultaneously press and hold the [ALC/STANDARD SURR] and [STANDBY/ON] keys for 10 seconds to enter this mode.
  • The display will return to the normal indication when no key operation is performed for 5 seconds.
BASIC OPERATIONS
#1 "5 (-> normal)" denotes that the display will return to the normal indication when no key operation is performed for 5 seconds.
#2 Indication when the BD function is selected.
Detailed Explanations
  1. When the procedures for Reset mode for numbers of protection detections are completed, all the counters will be reset to "000."
  2. Prohibitions:
  • The protection detection counts cannot be cleared (reset to 000) with the MEMORY CLEAR process.
  • They can only be cleared when the procedures of Reset mode are completed.
THE UNIT'S OPERATION WHEN AN ERROR IS DETECTED
  • The unit’s operation when a DC/OVER/TEMP error is detected is described here.
  • How to cancel the status after detection of a DC error is described here, because no key input will be accepted after a DC error detection.
BASIC OPERATIONS
TEMPERATURE [OVERHEAT] ERROR DETECTION
  • For detection of a TEMP error, the unit monitors both the TR_DET and PROTECT2 signals. If a TEMP error is detected, the processes shown below will be performed. The processes shown below are rough operational specifications and are not the actual commands from the mounted components. After a TEMP error is detected, the count of protection activation detections will be updated.
TO CANCEL THE STATUS AFTER DETECTION OF THE DC ERROR

Explanations
Simultaneously holding the [ADVANCD SURROUND] and [STANDBY/ON] keys on the front panel pressed for 2 seconds will cancel Key Input Inhibition mode after a DC error detection and turn the unit ON.

JBL MS-8 - 8 CHANNEL SYSTEM INTEGRATION DIGITAL PROCESSOR - SCHEMATICS - CONFIGURATION - CONNECTIONS - UPGRADING - RESETTING

May 14, 2013, 9:02 am
$

0

AUDIO OUTPUT CONFIGURATIONS 
  • Can configure the MS-8’s eight outputs in a variety of ways, depending on the speakers that are installed in your vehicle. You can configure the MS-8 for a system with one-way (full-range), two-way or three-way front speakers, a one-way or two-way center speaker, side speakers, rear speakers and one or two subwoofers. Remember, however, that the total number of available channels is eight, so any combination of front, center, side, rear and subwoofer channels cannot total more than eight. For example, if you are allocating six channels for a pair of triamped, three-way front speakers, there will be only two remaining channels, which will not accommodate a pair of rear speakers and a subwoofer.
  • If your system will include more than eight channels, use additional separate amplifiers (connected to the MS-8’s line outputs) for the additional channels. For example, if you want to build a 7.1-channel system that includes bi-amped or tri-amped front speakers, use the MS-8 to generate the 7.1-channel outputs (seven full-range and one subwoofer). Connect the MS-8’s front line outputs to the inputs of an additional crossover (or amplifier containing an additional crossover) that will provide the separate channels required to drive the front midbass, midrange and/or tweeters separately.
Use the Configuration Chart below to record which of your system’s speakers you have connected to which of the MS-8’s outputs. Keeping this record will simplify channel assignment during the setup procedure.
CONNECTIONS [SPEAKER OUTPUTS]
  • If you’ll use the MS-8’s built-in power amplifiers to drive your system’s speakers, connect the speakers to the MS-8’s speaker outputs. Insert the included speaker-output wiring harness into the MS-8’s speaker output until it locks into place.
IMPORTANT: The MS-8’s speaker-output wiring harness’s wires have clear insulation. Each channel has a copper (positive or “+”) conductor and a silver (negative or “–”) conductor. We have labeled each conductor with its channel number and polarity, and pre-stripped it for easy connection to your system’s speakers. Make sure that the ( + ) and ( – ) wires do not touch each other. Touching wires can cause a short circuit that can damage the MS-8.
  • To ensure proper polarity, connect each MS-8 positive (+) terminal to the respective “+” terminal on the speaker. Connect the negative (–) terminals in a similar way.
NOTE: You can power some of the system's speakers by the MS-8's amplifiers and some by outboard amplifiers, but you should use only one connection type per output. For example, output channel 1 may use the MS-8's amplifer OR an outboard amplifier, but not both. Be sure to use the chart above to note which speakers are connected to which MS-8 channels.
LINE OUTPUTS
  • If you’ll be using additional outboard power amplifiers to drive your system’s speakers, connect their inputs to the MS-8’s line-output connectors. You can power some of the system’s speakers by the MS-8’s amplifiers and some by outboard amplifiers, but you should use only one connection type per output. For example, Output Channel 1 may use the MS-8’s amplifier OR an outboard amplifier, but not both. Be sure to use the chart above to note which speakers you have connected to which of the MS-8’s channels.
DISPLAY CONNECTIONS
  • Use the included 6m (19.7 ft) cable to connect the display unit to the MS-8’s main unit’s display connection. Insert the cable’s straight connector into the main unit and the right-angle connector into the display.
NOTE: The display unit must be connected during setup but may be disconnected after setup and after you’ve made any additional adjustments in the Audio Controls menu.  If the display unit is disconnected after setup and final adjustment, you will not be able to make any additional MS-8 adjustments, and the remote control will not function.
MICROPHONE
  • The included binaural microphone headset must be connected to the MS-8’s Mic connection during the calibration/setup process. Once setup is complete, unplug the microphone headset and store it in a safe place. 
IMPORTANT: Do not use any other microphone with the MS-8.
UPGRADE
  • Use the Update port only for firmware upgrades. We have covered it with a sticker that you should leave in place until you are ready to install a firmware upgrade that you will download from JBL website.
  • After downloading a firmware upgrade into your PC, remove the sticker and connect the Update port to a USB port on your PC. Follow the directions that accompany the upgraded firmware to upload the new firmware from your PC to the MS-8.
MICROPROCESSOR RESET
  • If the MS-8 stops responding to the remote control (even after you’ve replaced the remote’s battery) or fails to operate in the way this manual describes, use a pen or similar pointed object to press the Reset button on the main unit
  •  Pressing this Reset button will NOT erase the calibration settings.
To erase all settings and set the unit back to factory defaults, this should be done in the system menu.

SELF DIAGNOSTIC FUNCTION
The units in this manual contain a self-diagnostic function. If an error occurs, the TIMER/PIC OFF LED indicator will automatically begin to fl ash. The number of times the LED fl ashes translates to a probable source of the problem. A defi nition of the TIMER/PIC OFF LED fl ash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the Remote Commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
DIAGNOSTIC TEST INDICATORS
When an error occurs, the TIMER/PIC OFF LED indicator will fl ash a set number of times to indicate the possible cause of the problem. If there is more than one error, the indicator will identify the first of the problem areas.

SETTING CONTROLS
  • Make sure the head-unit power is off and the GT-BassPro12’s Level control is set to minimum.
  • Set the GT-BassPro12’s Low Pass control to its maximum frequency of 120Hz and set the Bass Boost control to the 12 o’clock setting.   NOTE: If you are using the Remote Level control, set it to maximum.
  • Turn the head unit on and play a selection of your favorite music track that has substantial bass.
  • Adjust the Low Pass control counterclockwise until you hear only bass information coming from the GT-BassPro12. For example, you should not hear vocals coming from the subwoofer when you are seated in the normal listening position.
  • Adjust the Bass Boost control either clockwise or counterclockwise to suit your taste. Be sure to find a setting that does not create audible distortion in the subwoofer’s sound.
  • If you installed the remote level control, set the subwoofer’s Level control to its maximum and set the remote level control’s knob to the maximum level that provides undistorted output from the GT-BassPro12 with the head unit’s volume control at its 3 o’clock setting. Use the remote level control to adjust the subwoofer volume according to your taste while avoiding distortion from the GT-BassPro12.
  • If you did not install the remote level control, adjust the subwoofer’s Level control to the maximum level that provides undistorted output from the GT-BassPro12 with the head unit’s volume control at its 3 o’clock setting. After using the subwoofer for a while, if you find that this setting produces too much bass, you can reduce the subwoofer’s Level control setting.
  • Phase Switch: This switch will reverse the phase of the GT-BassPro12’s output with respect to its input. When you install the GT-BassPro12 with an existing factory or aftermarket system, changing the Phase switch setting to reverse the subwoofer’s phase may produce a discernable increase or decrease in the amount of upper bass that the system reproduces, depending on the GT-BassPro12’s location in the vehicle and the distance between it and the other speakers in the vehicle.
  • With the Phase switch set at 0°, play a music track that has impact drums, and listen for the upper bass content, paying attention to the impact of the drums. Then set the Phase switch to 180°, and listen to the same music again. There may be more upper bass, less upper bass or no change at all. The Phase switch position that provides the most upper bass is technically correct, but you can choose either setting according to your taste.  NOTE: In most cases the above steps will provide you with satisfactory results. However, the actual process may require several readjustments of each control, since the settings will interact with one another. If necessary, consult your authorized JBL car audio dealer for help in tuning your system.

CAUTION:  Using this product with the protection function disabled may cause further damage to this unit. Use special care for this point when using this mode.
Canceling Self-Diagnostic Function
  • Before canceling self-diagnostic function, execute setting for FACTORY PRESET of main menu No.24. (Memory initialization inhibited or Memory initialized).  # In order to keep the user memory preserved, be sure to select PRESET INHIBITED (Memory initialization inhibited).
  • Press the “ ” (Power) key of this unit to turn off the power.
Display provided when Self-Diagnostic Function started
  • The display is as described below depending on the situation when the last time the power to this unit is turned off.
  • When the power is turned off normally:
  • The FL display of this unit displays “NO PROTECT” then the main menu (sub-menu “1. ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later.
When the protection function worked to turn off the power:
  • The FL display of this unit displays the data of protection function which worked at that time then the main menu (sub-menu “1. ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later.
  • Note: When you reactivate the self-diagnostic function after turning off the power once by pressing the “” (Power) key, “NO PROTECT” will be displayed because that situation is equal to “1. When the power is turned off by usual operation:” described above.  However the protection function history is stored in a back-up IC with a backup. For details, refer to main menu 21 PROTECTION  HISTORY.
When the protection function worked due to excess current.
                               NO PROTECT   è   1.ANALOG BYPAS
Cause: An excessive current flowed through the power amplifier.
Supplementary information: As current of the power amplifier is detected, checking the current can identify the abnormal channel detect transistor.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off.
Notes
#  Applying the power to this unit without correcting the abnormality can be dangerous and cause additional circuit damage. To avoid this, if “PS” and “DC” protection function works 3 times consecutively, the power will not turn on even when the “ ” (Power) key is pressed.  In order to turn on the power again, disconnect the power cable of this unit from the AC outlet once and then reconnect it again.
#  The output transistors in each amplifier channel should be checked for damage before applying power to this unit.
#  Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.
When the protection function worked due to a short between speaker terminals.
                                    I PROTECT
Cause:The line between speaker terminals is shorted.
Supplementary information:As the excess current is detected after operation of the speaker relay, the shorted speaker terminal and the connected speaker can be identified.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off.
When the protection function worked due to abnormal DC output.
              DC PRT:xxxH [AD value when the protection function is working]
Cause: DC output of the power amplifier is abnormal.
Supplementary information: The protection function worked due to a DC voltage appearing at the speaker terminal. A cause could be a defect in the amplifier.
Turning on the power without correcting the abnormality will cause the protection function to work in 3 seconds and the power supply will be shut off.
When the protection function worked due to abnormal voltage in the power supply section.
            PRV PRT:xxxL [AD value when the protection function is working]
Cause: The voltage in the power supply section is abnormal.
Supplementary information: The protection function worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 seconds and the power supply will be shut off.
