REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

JBL BPX2200.1 - 2-CHANNEL POWER AMPLIFIER (CAR) - WIRING DIAGRAM AND CIRCUIT DIAGRAM

JBL BPX2200.1 - 2-CHANNEL POWER AMPLIFIER (CAR) - WIRING DIAGRAM and CIRCUIT DIAGRAM

SCHEMATIC & WIRING DIAGRAM_JBL BPX2200.1-CAR-POWER AMPLIFIER_2-CHANNEL
SPECIFICATIONS
Power output – 2 Ohms > 1100W x 2
Power output (bridged)-4Ohms > 2200W x 1
Power output (parallel) – 1 Ohms > 2200 x 1
Minimum speaker impedance > 1 Ohm
Frequency response > 20Hz to 320KHz – 3dB
Input sensitivity (RCA Type) > 250mV – 6V
THD + Noise {4 Ohms} > 0.5%
Signal to Noise ratio > 93dB
Maximum current draw > 190A
Fuse replacement > 150A x 1
All tests to be done, unless otherwise specified, from 10Hz to 320Hz at 14.4V DC into 2 ohm loads and adjust the units gain so that with a .775 volt input signal the unit is at its maximum rated output. All measurements will be done using an Audio precision system one and the supply voltage.  An A+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless otherwise specified. The voltage applied to the unit shall be measured at the power connection on the Amplifier. Signal Source Unless otherwise specified, all tests shall be conducted with the Audio Signal Generator output configured to be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shall be connected to the Amplifier PWR GND at the Amplifier. Output Load Unless otherwise specified, all tests shall be conducted with 2 ohm resistive loads having less than 10% reactive components at any frequency below 350Hz. Each resistor shall have a value that remains within 1% while dissipating the rated output of the unit under test. Power Indicator LED steadily illuminates for normal operation. LED blinks when protection circuitry is engaged, and during power up. SCHEMATIC DIAGRAM
WIRING DIAGRAM
APPLICATIONS – BPx MODELS
To the right are several application diagrams to help plan your subwoofer system installation. Figures 1 through 3 show how to configure the JBL Power Series subwoofer amplifiers (models BPx500.1, BPx1100.1 and BPx2200.1) for 2-channel, bridged-mono and parallel-mono operation “Setting the Output Mode” )
NOTE: For simplicity, Figures 1 through 3 do not show power, remote and input connections.
NOTE: If the nominal impedance of your speaker system is close to 2 ohms, be prepared to try both bridged and parallel configurations to determine which performs better.
