If fuses keep blowing there clearly is something wrong with the power amplifier. You can start by getting access to it and doing a visual inspection for signs of overheating or short circuits but then it will be necesary to check parts and eventually you will be able to isolate the defective part(s) and repair it.

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.

Hi there, my relatively new Mackie Thump wont power up despite being plugged in / on etc. When I do with it on all i hear is a very low pop sound every 5 to 10 seconds or so


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

No power in Mackie TH-15A


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.

No sound coming out of my mackie


Whether you are experienced in electronics repair?
if not, try this simply way:
1: Test whether the power amplifier is still working. See figure 1.
Power OFF,adjust the EQ settings as shown in the picture.
Minimize LEVEL.Switch ON Power. Touch pin 3 at the INPUT socket by using a small screwdriver or piece of wire / cable.
Slowly raise the LEVEL,a little bit only (as the clock showed 7-8) until
sound is heard in speaker. If not heard, slowly raise again LEVEL.
If audio input signal is heard,it can simply be taken to mean
that the amplifier is working.
If LEVEL at 9 o'clock position,and the audio is not heard,
the possibility of the amplifier is damaged.
Switch OFF the power. Take it to a repair place.

2: When the Power LED is lit, but no sound,
There are many possible causes, one of which is:
I have been getting 3 times similar cases, and all are caused by
two Rectifier-Diode (either or both.) damage on the power-supply-unit.
Remove/desolder,measure, if damaged replace it with a new one.
See figure 2-3.

Almost certainly the amp has failed, as per usual with these, you need to take it to the repair shop and see if it's worth fixing it then sell it once working or for spares if not. Sadly whilst Mackie make some really good kit their powered speakers are not amongst the most reliable

Hello, I recently bought a Mackie Profx8 mixer here in the UK and I cannot locate the fuse. The AC socket does not have the fuse tray underneath (unlike my Mackie speakers) and there is no indication...


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.

Need to find out which is the proper speaker wires for hook up yellow to tweeter or sub? And striped one is positive or negative?


You can probably trace which colors go to the smaller of the amps... Yellow is often used for tweeter but there really is no standard. Striped wire is probably the minus lead. If a pair is heavier, that would be the pair for the woofer... and red is often positive for woofer and black the minus. Searching the Mackie schematics doesn't really show colors. You could call their service dept.
