As I said literally 2 posts above, there are NO schematics for this device in the public domain. We would all love for somebody working at a QSC authorized repair center to accidentally upload the diagrams to somewhere like ManualsLib, but I'm not holding my breath. I believe that it is...

Based on the 41* code, it looks like this might be a P-channel MOSFET, and might be one of the following 3 devices - for those not aware, SMD packages do not have enough space to etch a full identifier, so typical identifiers are 1-6 alpha / numeric characters, which then need to be decoded to a...

Check post #27 where I discuss an additional problem I discovered after replacing the caps that resulted in lower than expected volume on one channel of the mains. Summary... tiny surface mount resistors could be bad or damaged.

You don't really talk much about the condition of the unit, or it's age, but a few observations... these units are constructed from a bunch of boards which are linked together via ribbon cables. If you live in a humid climate and / or have bumped the unit around a lot, something may have become...

When I say "here", I mean Latin America, not "SoundForums". Sorry if that was not clear or obvious, English is my 2nd language, so mistakes can & will be made. Also, I'm discussing LIVE sound, not recording studio sound. For live sound, you really want a more nasal bass sound to cut through...

The crackling noise is the sound of the voice coil jumping out of the magnetic gap due to excessive excursion / cone movement. Keep that up, those speakers won't be long for this world. Indeed, they may already be toast. You don't mention what size of rooms you play in... I mostly do medium...

The Behringer P2 is awesome for the price. It has 2 faults that are not (in my opinion) deal breakers. The first is that the mechanical release button that holds the case on is not in the dead center of the device, so even though the steel case / shell should in theory fit on the guts in...

What he said!!!!!!! You connect the output terminals of 2 unique, distinct amps, you WILL end up with 2 blown amps & a large repair bill. PERIOD!!!! I've been working with & repairing these things since the Crown DC300 was a thing, and I GUARANTEE you will get fried amp omelet if you proceed...

Look, it boils down to this: Are these speakers important to you? Does your reputation depend on them working strong & solid, night after night? Or are they end of life ratted out cabinets that are going to be retired soon?? If it's the former, then why risk your reputation to save money on a...

In my opinion, trying to save the ferrofluid is a terrible idea. You might compare it to re-coning a woofer & re-using the old spider, although that is very inexact comparison. You have zero confidence that ferrofluid is clean & free from debris caused by the failure of the diaphragm. The...

One other thing that I'm not seeing in YT videos that I always do, although ferrofluid will complicate this somewhat: I always clean the magnetic gap before installing a new diaphragm. This is especially important if the diaphragm shattered or otherwise cracked or split (or in the case of...

The compression driver for the SRX 715 (and SRX 712) is JBL 339894-002X aka 2431H / 2431HPL. Rather pricy at close to $400 from reputable parts stores in the USA. The diaphragm kit is called JBL D8R2431 and is a quite frankly shocking $210. Ouch. Oh, I see, this is a ferrofluid filled driver...

Just wanted to mention as a general comment for your future reference (none of the products you mentioned fall in this category): Be VERY suspicious of ANY powered speaker advertising "Class D" power in the 800w to 1500W range built from about 2010 onwards including everything on the market...

Yes, my bad, meant to say low B for the 5 string (assuming BEADG tuning). For some reason, all the bass players have gone nuts buying 5 strings in my country, not sure if it's the same in the first world countries or not. Nothing wrong with a good old 4 string in my opinion, but I'm old - lol...

Have you considered getting a Behringer X32 Rack (or similar digital rack mixer)? Then you can keep all your wires on stage & mix from a computer wherever you want to be in FoH. Even walk around with it & check your sound from various points in the venue, especially easy if you get some kind of...

Totally understand, George. Once you have a bad experience with a product, not matter what it is or how good it theoretically might be, you never want to go back to it. Just as a FYI, I use Behringer XAir mixers frequently, specifically the XR16, XR18 & X32 Rack. There is a steep learning curve...

The reset button seems to reset technical settings of the mixer. For example, in my case if I set the mixer to 48KHz sample rate, reset puts in back to the factory default of 44. The manual describes it like this: Reset Mixer – Resets all mixer controls to factory default. This does not erase...

Lets take a moment to recap (ha, pun intended) the situation: Where did the polarity reverse info come from: In posts #3 and #5 above by Brian Ingwell, he confirms that there is an official QSC service bulletin regarding the possibility that the output caps may be installed in reverse polarity...

Yes, I guess you are at the point where going to QSC official service is the only option. I don't know if they do component level repairs, or if they only do board swaps. Since QSC seems to be out of stock of just about everything electronic (definitely the TM replacement main boards, I asked...

100% agree on doing a factory reset & reloading the default profile. It's easy to get settings messed up that might affect output levels. If that's not it though, I do have one other idea for you... The TM16 I worked on was badly brutalized by a caveman (I can't even call whoever this person is...
