    JBL PRX518S schematics

    Hello,

    Anybody here have access to the schematics for the JBL PRX518S power amplifier module that you would be willing to share?

    I have one in the shop with the typical shorted mosfet pair that I replaced but still does not power up.

    Thanks in advance!

      You're in luck, i bought only the amp module (faulty) off eBay a while ago, and the local Harman distributor was kind enough to send me the service documentation for it.

              Although i should warn you, at least on mine, when i tried to power it up with the four fets from the amp removed, i managed to blow the two IGBT's in the power supply

                  How to test Subwoofer Amplifier with only a multimeter
                  by jinu_j
                  Hi Folks

                  Need some advice on how to test a subwoofer amplifier if i have access to only a multimeter.

                  Problem
                  I have a Boston Acoustics active Subwoofer (soundware S). Its rated output is 200W. But the output i am getting is very low i can barely hear/feel it even if put the gain at max. I replaced all the capacitors in the Subwoofer amplifier but still no change.

                  Is there anyway to test this without getting an oscilloscope/Function generator to see if the fault is with amplifier, driver or the source??

                  Any advice would be appreciated...

                  Asus Nexus 7 2012 (ME370T REV 2.4) Schematics needed
                  by Popalwali
                  Hello Everyone,

                  I will be really grateful if someone shares schematics and if possible the boardview of the old Asus Nexus 7 (2012) Tablet. The motherboard is ME370T Rev. 2.4. Now I can find schematics for the Rev. 1.0 but I could not find the schematics for the Rev 2.4. I tried to look for similarities in the Rev. 1 but there are somethings missing, plus the board i have has nearly no component names printed on it which as a newbie makes pretty hard for me to locate things. Any assistance will be appreciated. Thank you.

                  If anyone needs schematic diagrams for any pro audio gear like what professional musicians use, such as guitar amps, power amplifiers, vintage tube amps, musical gear like keyboards, effects pedals, guitar wiring diagrams and service manuals, check out https://schematics.ca . I'm a road musician and an electronics tech and I got schematics for just about every piece of gear in my band from this site and they are free to download. It's always good to be prepared in case you fry something while on on the road, which always happens it seems. https://schematics-free.com has a lot of free audio schematics...

                  Mackie CR4 amplifier no sound
                  by UserXP
                  Hi, people.

                  I've got an amplifier assembly from Mackie CR4 parts. It's just an amplifier, there was no speaker housing, so I used my set of CR4s to test it.

                  Anyway, upon connecting everything and hooking the "new" amplifier to an audio source, the sound played clearly and strongly for the first ten seconds. I was happy it was working. Then the sound started to fade out during the playback until it was no more. After it had "dropped to zero", there were two very short intervals of sound playing at the normal volume, as if the amplifier was trying to...
