Mackie Thump th15a no sound coming out of the speaker. It has power but no sound.
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.
Hope it helps. Regards.

Hi Tommibg, i have the same problem with my mackie thumps,the Diodes pictured above are the problem and need replaced,however,i cant source them any sugestions welcome,also which diode is the reverse polarity one thanks.
did you find out which diode is the reverse polarity?
I've fixed a pair of these recently & whether I just got lucky or not, it was just bad solder joints in the DSP unit, particularly around the connectors to the amp module. They are all pretty ratty coming out of the factory..so a remove & resolder did the trick.

Are you sending the main mix to the monitors or are you giving them their own mix? What about using the sub groups, use 1 for your monitor send.

Don't know your setup but have you checked out any possible Hum loops? Have you updated any firmware updates? Is your mains input clean (no spikes or very short drop outs of voltage)? Are you near any possible RFI, e.g. Taxi's or CBr's? The list goes on so check out the Mackie forum on the web for more. Good Luck...
Regards,
Frank.

My best advice to you is to get your stands where I get mine - on eBay. They usually have a great selection of stands, tripods (although I personally would not put my nice Mackie reference monitors on tripods - too unstable).
Also, you will most likely find them for quite a lot less on eBay.
However, I believe Musiciansfriend.com (my favorite web site) may be having a fall sale very soon, or end of summer sale, and they have been known to reduce their prices heavily on things like stands, sound reinforcement, and other accessories during a big sale.
If FixYa sold such things, I wouldn't be sending you anywhere off site, but since you cant get them through us, I am giving you my absolute number 1 and number 2 choices that should solve your problem well.
If looking on eBay, be sure to measure your monitors, or get the information from the literature that came with the monitors. It's bit easier on Musiciansfriend.com, and here is a link to the stands they havce available there:

Another option is monitor wall mounts, as we have to two of four reference monitors in our home studio wall-mounted, and it's great getting them out of the way and not taking up floor space or valuable desk space.
I hope whatever decision you make will be one you are happy with.
Thank you for using FixYa.

Refer to your EV user manual, page 23, part 2.
You run the outputs of the Mackie into the stereo "returns" on the EV.
Use TRS interconnect cables as these are balanced lines.

Crackling is usally one or two things my guess would be bad grounding of the amp or bad connection with the jacks or plug it self try to make it crackle on purpose by jiggling the jacks see if it has any effect on the crackling try to narrow your possibilitys
Testimonial: "ok you think it is an electrical issue and not from the speaker I tried other wires. I believe the place has bad grounding to the outlets. Thank you"
