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...

Mackie srm 350v2 speaker packed up


I believe there is an internal fuse in these which, according to a friend who has these, seems to blow occasionally for no apparent reason. He has also had to send two back for replacement and would not buy again, they seem to be inherently unreliable although they sound great.

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.

Need spec on Mckenzie loud speakers 12'' dual cone 85 watts rms


What\'s the question, are you asking about eyebolts, SRM 450 or McKenzie speakers?



Let\'s assume speakers. These are quite nice vintage speakers and were fitted in a number of units back in the day. Depending on the use they are going to be put to you\'ll need to find the dimensions of similar boxes for the same use and speaker size from (ideally) makers who used these speakers or something similar. It\'s going to be a bit suck it and see and will also depend on if you are looking to use an infinate baffle, sealed or vented enclosure.

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!

I have Mackie SRM450v2 speakers, one has no power, I think the fuse has blown, it it possible for me to change this myself? The manual says it's not user serviceable.


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:

http://elektrotanya.com/mackie_srm450_active_speaker.rar/download.html

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.

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

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!
