This speaker at full power draws average 1.3A at 230V and 2.5A at 120V. Mackie's recommended fuses are in line with this so your fuse is actually too high a rating. It is possible you are using cheap fast blow fuses or are over-driving the speaker (which should cause the fuse to blow) These speakers are only capable of 118db sustained (@1M) so cannot be expected to cope with anything but small venues or gentle music.

SOURCE: How do I replace the fuse on a Mackie SRM 350 v2?

The fuse is inside and is to be replaced ONLY after you repair the cause of it blowing. Additional damage may result if repair is not made first. Power it up with a 150 watt light in series with the power cord as a resetting fuse. When light remains out, unit should be good.

The fuse is mounted on a circuit board behind the power input connector.

Here is a link to a service manual that is probably close to your unit:

Scroll down at the web page to a small link that says "Get Manual" Click on that and after download unzip the file... it is free... ignore the winrar thing...

Chances are if the fuse has blown, there are failed electronic components that caused the failure.

Scroll down to the "Get Manual" on the site and click on the link. The file is compressed. The first part is the schematic, the second the assembly and parts list. Likely the main low freq power amp has shorted transistors.

Essentially if the fuse goes, the unit is rendered useless until it is repaired. Replacing the fuse without repairing would likely cause further damage in the unit. Fuses blow for a reason that is usually a failure in the unit. Failures don't fix themselves. The ability to replace the fuse is therefore a moot point. To keep your unit safe ALWAYS power all interconnected equipment from the SAME power receptacle or conditioning module. This means running extension cords to powered speakers if that is what you have to get power the mixer. Powering mixers at one end of a room from a receptacle and the amps or speakers from a recpetacle on a stage at the other end will likely damage you equipment when a ground fault occurs or ground bounce in the building wiring ruptures the sensitive input/output circuits of your equipment.

No power in Mackie TH-15A


i) I assume the fuse you mentioned was in the mains plug - did you also check the fuse in the TH15A mains input socket? This is accessed by pulling out the tab in the bottom section of the socket (below the centre pin). This is a 3.15Amp antisurge fuse, 20mm type.

ii) If this fuse has blown, then replace it & all may be well ...... but if it blows again, then move to step iii).

iii) With mains disconnected, remove rear panel (outer screws) & check the power supply PCB for damaged components, especially R111 & R112 (100ohms). If the latter are burnt or open circuited, then the amplifier module may have blown.

regards, Dave

It is likely that the O/P transistors have blown, especially if the fuse keeps blowing and the O/L led comes on. It's a repair shop jobbie

What size internal fuse on mackie srm450v2 speaker


Mackie say this is not a user service part. If the fuse has blown there is probably a fault in the unit being their reasoning. I know for certain they tend to blow for no apparent reason so it is worth giving it a go. They are 5 x 20 Slow or time fuses. 7A for 120V and 4A for 230V

I used my monitors at high volume for approximately 1 hour and they stopped working. One monitor has no volume and the other has very low minimum volume.


You may have blown a fuse in the amplifier. Refer to Appendix A: Service Info in this guide http://www.mackie.com/products/mr5/pdf/mr5_om.pdf under No Power section, and if the fuse it not blown, try some of the solutions under No Sound. Hope this helps!

Srm350 active-2 internal fuses on pcb-one had blown replaced it turned power on but it blew again-any ideas-it was working o.k. then blue light went off-still power to speaker


Either a short in the power supply such as diode(s), capacitor, or transistor(s) or in the power amp. It will require service. Replacing the fuse before repair will likely damage more components... don't do it!

So, i think I've blown the fuse in my Marshall MG 100 HDFX head (I tried to run 2 speaker cables out of the head into a quad...stupid >.<). What type of fuse do these heads use? How can i access...


The fuse is inside the unit so as to force you to open it and look for damage.

The fuse is likely a 3 amp/250 volt type.

Replace the fuse and then put a 100 Watt light bulb in series with the hot side of the power input. If the lamp stays lit with no load on the unit, then there is damage that requires repair before use. If you just replace the fuse repeatedly you may damage further components.

In the future obey the minimum resistance load on your amps.

Where to buy fuse


http://www.fender.com/support/amp_schematics/pdfs/Bassman_400_Schematic.pdf Also note there is a thermal protection circuit and a current overload. If the amp turns on and there is no sound start with the speaker to make sure it isn't blown and work backwards through the wiring and connections up to the crossover circuit (all in one cabinet version). On the head separate versions check for a broken output jack problem. The fuses are 10 amp 250 volts for the 100-120 volt models and 5 amps 250 volts for the 230-240 volt models. NOTE: If you are at all unsure about opening your amp up to work on it, take it in to be serviced. It doesn't sound like a fuse problem to me. Necer work on an amp while the power cord is plugged in. Always replace parts with the proper replacement especially fuses. They are there to protect the circuits. If they keep blowing it means there is an internal problem. Remember that capacitors store a lethal charge and it is easy to touch the wrong thing when you are looking inside an amp even if it has been disconnected from power for a while.

Mackie CR 1604 - Fuse keeps blowing


This is a rare occurrance for these units. It means that either one or more of the rectifier diodes has shorted or that one of the voltage regulators is bad. In any case, this is not a unit I would suggest a novice attempt to repair. Can you update this with your location so I can suggest a repair center? The actual repair should be straightforward and not too expensive. Thanks, Dan
