Question about Mackie Srm 350
The mackie 350 i have i bought used. The fuse has blown three times! It is 1.6 AMP 250 VOLT. IS THIS THE RIGHT FUSE ? or did the other owner replace it once with the wrong one? If this is the right one then i know its a bigger problem then just the fuse. PLEASE HELP. what is the correct fuse for this speaker???
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.

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:

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.

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.
