Replace ac fuse on mackie sr1530 - Mackie PPM608 / C300z PA Package

If your Mackie SR1530 is powering on but you're not getting any sound, there could be a number of potential causes. Here are a few things you can try to troubleshoot the issue:

1. Check your connections: Make sure that all cables are properly connected and securely plugged in. Check both the cables going into the speaker and the cables that are connected to your audio source.
2. Check your audio source: Make sure that your audio source is turned on and properly connected. Try connecting a different audio source to the speaker to rule out issues with the source.
3. Check the volume levels: Make sure that the volume on both your audio source and the speaker are turned up. Try turning up the volume to see if you can hear anything.
4. Check the input settings: Make sure that the input settings on the speaker are correct. For example, if you are using an XLR cable, make sure that the input on the speaker is set to XLR.
5. Test the speaker with a different audio source: If you have access to another audio source, try connecting it to the speaker to see if you can get any sound.

If none of these troubleshooting steps work, there may be an issue with the speaker itself. It may be a good idea to contact Mackie customer support or a qualified audio technician for further assistance.

Be sure the capacitor was replaced with the correct polarity?
in the beginning of my tech career I have replaced caps back words on accident. ..

Your best bet is to contact Mackie Tech Support. Here is a link to their Suppot page. Mackie Tech Support
it's likely it needs to go to a repair shop. Here is a link to their service center finder. Mackie Service Center Locater

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.

I suggest either replacing these OR taking them to a professional to be serviced. Fuses blowing are a sign of serious malfunction and inexperienced DIYers should not attempt to induce the Darwin Effect

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.

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.

There are more than one fuse and they are internal. Replacing the fuse without fixing the cause MAY result in causing more damage to components. The fuse is inside to force one to open the box to repair.

I would contact Mackie and see what they say. The MR5 is already protected internally by the built in amplifier circuitry as far as I know.They can be reached here:http://www.mackie.com/support/index.html

You should order an exact replacement from Mackie since this is a reference monitor.

Consider putting a limiter or fuse in series to protect the speakers if this was due to overdriving it.
