Fuse for M3 in the UK.

Orbvs_Tomarvm · Post by **Orbvs_Tomarvm** » Mon Nov 16, 2009 7:36 pm

Hello forum,

Can someone please tell me what fuse (3, 5, 10 or 13amp etc) i should be using in the power cable plug of my M3 (in the uk). Or let me know what fuse they have been using safely thus far.

Thanks in advance, Tom.

Tom,

A 3 amp or 5 amp fuse would be best.

Regards,
Rob

3 amp or 5 amp

Really? Oh shoot. Looks Like I've got my wires crossed there then... Found a 10 amp fuse in my extreme, and a 13 amp in the classic triton. I bought the extreme second hand, so i guess that means anyone could have put that there, but i bought the classic triton brand new, so i kinda assumed that the fuse the manufacturers supplied was the dead cert. Although i take it that the power consumption differences between the different machines would account for them requiring different fuses? Is that right? And can anyone else attest to the 3 or 5 amp fuse theory who operates an M3 in the UK? Cheers.

By the way, i used the M3 with both the 10amp lead, and the 13amp one, so does it really matter?? Sorry if my post seems a little frivolous; when i used the M3 with the afore mentioned amp'd leads, i was only really testing it, whereas now i am going to be using it for long periods of time, so thought i'd best not take any risks. Got the kettle lead, just need the correct fuse now.

Thanks again in advance forum, and thanks very much for your reply Rob mate, its very much appreciated.

Tom.

Tom,

The M3 consumes 35 watts (= V x A). The UK supply voltage is 240. The AC supply current drawn by the M3 will therefore be 35/240 = 0.15 amps. You want to use the lowest rated fuse that will not blow, to provide maximum protection from electrical faults. A 3A fuse will be best, but they are a little hard to come by. A 5A fuse will be just fine, you can get them anywhere.

A typical kettle has a 2 Kw heating element (= V x A). The current drawn by a kettle is therefore 2000/240 = 8.3 amps. So it should have a 10A or 13A fuse in the plug.

Regards,
Rob

Yeah Rob, i found that out. I put a 3amp fuse in and have all three keyboards running tickety boo

Just need to figure how to hook them all up to optimum advantage... i currently have the M3 midi'd to the triton pro in a master/slave scenerio, and have the extreme output L/R to audio in 1&2 to the M3. Its interesting but i don't really like it

Does anybody have any better ideas?

Thanks again for all your valuable input Rob, its greatly appreciated.

Tom.

Tom,

That's how my Pa2x is connected to the M3 at the moment (until the M-Audio NVP-10 arrives in a few weeks time).

What isn't right about your setup, maybe I could help fix it if you can describe what youdon't like about it?

e.g. you need to remove all EFX routing from line inputs 1 and 2, plus set the levels using the left hand two sliders in EXT input mode. I use a Combi to save the settings. Then it should sound pretty cool.

Best regards,
Rob

Hi

35/240 = 0.15 is correct but this will have a 2.5amp fuse inside the unit which will cater for this.

As a manufacturer we can't cater for users (at gigs or in the studio) always connecting the correct 3 pin plug with the correct fuse rating inside. So we put another fuse on the inside which will blow first for this reason.

Didn't know that Mike, that's very comforting to know.

Kind Regards
Sharp.

Is this a user-servicable part? I'm assuming it will be, but because I don't read manuals properly I didn't even know it had one

Hi

Yes it can be if you adhere to the correct electrical safethy precautions. If you are in doubt please have a qualified service engineer look at the problem for you.

Excellent responses (again!) Thank you forum.

Hi Rob,

I've set the inputs to L/R, but didn't know what you meant by using the two left hand sliders in EXT input mode... is this on the same 'sampling audio in' page? and is it just setting the volume levels for left and right? Could you run that one by me again please.

Cheers, Tom.

I'm looking at buying a M3 from a friend in the US and it looks like some of you may have answered the question of power supply.

In Australia we also have 230-240V power as standard.

Reading through the post it appears that or would I be correct in saying the M3 has a switching power supply like my Virus TI?

So regardless of which voltage you put through it 110V ov 240V the M3 will work in both UK/US/AUST?

But the cord must be properly rated with secondary fuse with the M3 internal fuse as the first line of defence?
