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

Here is a service manual that will be CLOSE to your unit, though not exact:

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.

Power supply circuit diagram


There is almost certainly a reason the PSU has blown, these are not very reliable units and the amp has probably gone and taken the PSU with it. You are better off taking it to a dealer and getting it fixed. If there is no power on the seecondary and there is no short the transformer must have blown (assuming you're not trying to check with a DC meter)

My speaker sounds like it is blown


take it to a Sound Production company and ask their opinion. If they use Mackie gear-even better. They will better be able to tell you what's goin' on if they hear the speaker. Good luck.

Do i have the right fuse


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.

Problem with the Mackie SRM 450 v2


It would be very unusual if the blue LED is burned out. They should last a million years. I suspect the power supply has a problem.

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

ONLY GETTING MUFFLED SOUND FROM ONE OF MY MACKIE SRM V2 SPEAKERS,HAVE CHANGED DIAPHRAM BUT PROBLEM STILL THERE


If you've changed the tweeter and the sound is still muffled the fault is with the HF amp, or the cross-over. You will have to send the amp assembly for repair as it is all surface mount components in there -nothing you will be able to fix yourself. Sorry for the bad news!

Problem with Mackie SRM450V2: HFsignal bleeding through LF driver,low HF OUTPUT also. Filter problem i suspect.


There is an entire crossover circuit inside that is BEFORE the amp section. There are 2 separate amps: one for HF and one for LF. Can you describe the noise you are hearing in more detail? Is hte sound effected by the gain controls at all? What happens without any input?

Thanks,
Dan
