Change internal fuse on battery. Unit will not work unless battery is connected but battery needs fuse to be good

Diagram is NOT likely to help much. Look for bad soldering at the input and output jacks AND by the power input jacks. Also look for cracked circuit board and or lifted circuit etch. Lastly, the pots and the soldering around them may be part of the problem. Most of the mentioned things are 95% of the problem.

Here are the chords: Don't be confused by the video. The guy is capo'd up a whole key, so his fingered G actually is the A shown on the chorded lyric sheet. Enjoy.

There is power from the power supply if the logo is on the screen, although it could be it isnt providing full current. Whilst the logo is displayed the machine carries out a number of checks to ensure it is working correctly. Once these checks are completed it moves to showing the voices etc. If it hangs it has found a fault and further investigation will be required.

Behringer only gives schematics to their authorized service people.

I find I can usually trace stuff out as needed as the mixers are a very symetrical repeating circuitry.

Most components are readily available from other sources.

It’s not likely you can. I’m repairing my board right now from the burnt crisp in one corner.

Assuming that you've checked the fuse, and the lights come on...1) Can you hear any "hiss" from the speakers at all? 2) What have you tried to input into the device? (guitars, keyboards, mics, etc.)3) Have you reset all buttons to "basic" mode? Let me know, and we'll go from there...

This link might help: or you can also request the manual from Spectrum.

That appears to be Italian in our English speaking website PMP 4000. Start the source a little and then the supply voltage of the amplifiers disappears Only Behringer can fix

For those who still suffer from crackling potmeter in DigiDesign 003: Well, this potmeter is not the top of the line. I made weeks of researches to repair my friend's DigiDesign003 crackling headphone+mainvolume potentiometers. We decided to find replacement-parts which is much cheaper than the $10 assumed here above. Here's the significant part of what I found (posted at avid forum as well): I attached an Excel-datasheet-screenhot which contains all the possible candidates, however I couldn't find some of the potentiometers at distributors, USA people may have better luck to find the most fitting one. Fortunately BI Technologies in UK produces a rotary audio-potmeter line which fits the 14mm dimensions of the Digi003 built-in potentiometers. (Our local distributors could only acquire a similar to similar P140KH1-20AR20K from BI Technologies, it needed a little bit of tweaking, rasping, but it now operates fine and is durable - 30000 turns - on paper .) The extracted info of the Excel, the most fitting models (datasheets help to find correct/closest part-number): -BI Technologies(UK) P140KH-F25AR20K (confirmed to exist by BI contact but distributors haven't ordered this yet, needs 9 weeks of shipping if you manage to order it. Above I mention, BI P140KH1-20AR20K is proven to work and BI potmeters bear 30000 turns, 2 times more than other brands.) -Bourns(USA) PTV142B40Y025AA203 (unfortunately DigiKey and Bourns told it's obsolete) -Noble(USA) XV014112GPV-25F-15A20K (seems very similar to the original DigiDesign003 potmeter. I have no info, how to order. Maybe directly from manufacturer.) -Alpha(USA) 3RP/1416G-CD1-D20K (probably orderable from Alpha directly by using their web-interface to assemble part-number.) -Alpha(Taiwan) RV142F-40-25A-A20K ? (datasheet/xls may help with correct partnumber) -Alps(Japan) RK14K12C0A0T (its value is 50kOhm, not the best replacement-candidate) Distributors I found (in approximate order from biggest to smallest): USA: Arrow, DigiKey, Mouser (shipping outside USA costs around $60) Europe: Farnell/Newark, RS-online, Distrelec, Conrad, Allied, TME Some last observations, advices to select correct part: -must be 2 * 20kOhm, logarithmic scale for audio application (A taper) -these 14mm dual 'audio' potmeters seem to have the same 'standard' pinout, but 'tone' (bass/treble) potmeters has a bit difference: common point is separated to 1st and 2nd leg. We simply cut the end of 1st leg to be short (not to reach PCB) and solder it to 2nd leg (see 1st photo), and it seemed to be perfect 'audio' potmeter substitute in our case. Check out datasheets or my excel for pinout-details. -the shaft/rod of the potmeter should be 'flat' type with cca. 6mm diameter, 4.5mm flatted-part thickness and 12mm flatted-part length. -the complete potentiometer should be around 25mm tall. datasheets state it as 'L' parameter, but be careful, it differs for potmeters with bearings, where it refers to the shaft-length. Drawings in atasheets make it clear hopefully. It seems that our potentiometer which unfortunately had bearing, still fits into the DigiDesign003 fine... -most of the times the orientation of these panel-potmeters are referred to as 'vertical' which means they stand vertically and their legs are bent to fall into the PCB, as well as their securing point is at the bottom. The drawings in datasheets help to identify if its that way. I hope this ordering & technical info was a little bit of help for some people. Sorry in advance if any of the presented info here were incorrect/misleading, I tried my best, and don't take any responsibility for the correctness, so use the info at your own risk... Good luck, if you decide to acquire and replace the potmeter for yourself... For non-technical people I advise to ask someone skilled in soldering because it's hard to desolder the original potentiometers from the Digi003's 2-sided panel... Soldering flux comes handy to lower the melting temperature of tin. Flux can be cleaned with acetone after soldering the new pots in. It would be useful if you might post any results here if you used any of the pots above... b5f78999-5206-4219-9814-477b70eebbeb.jpg 05f5d0a8-417c-4c1a-973e-8ee7446a4b8b.jpg 50160b02-6f81-445f-9440-9af226813a2d.jpg d717e64c-ad09-4bcf-ba04-6d1e61359d94.jpg 41b20c96-c0b8-462e-9e58-edc6c94e0b10.jpg

sounds like bad caps and maybe a failing output transistors. Use Deoxit contact cleaner too.

Fender Frontman... • Answered on Mar 02, 2021

I would expect there is bad soldering or a circuit board crack. Inspect the soldering aound the leads, especially pots and heavy components. Finding all the retaining screws can be frustrating. Expect the screws for the handle to also attach to the amp chasis. They are often hiodden under plastic caps.
