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.

    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.

SOURCE: hooking up powerd monitors to a Mackie 1604 VLZ3

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.

SOURCE: Mackie D8B Mixer freezes

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.

SOURCE: stand for Mackie MR5

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:

http://www.musiciansfriend.com/navigation?q=monitor+stand

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.

SOURCE: Connection of two sound boards

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.

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.

I had Mackie th15a 110vac and it had busted fuse, when i replace it when a new one it got busted again...i plug the power cable to 110vac without a regulator. what would be the problem in the power...


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

My Mackie Thump TH-15A will not produce any bass. I can get some sound but only from the top tweeter. Whats wrong and how can i fix this?


Could be the crossover has died or the main speaker winding has failed. Open her up and connect on side of the main speaker direct to a 9v battery and then wipe the other wire over the other terminal. If you get a crackling from the speaker then it's likely the crossover, if there is no response at all from the speaker then it is dead and possibly the crossover too.

Bought a used Mackie TH-15A. When powered up there is no sound...at all.


The internal amp is in need of repair. Are there any other symptoms or signs?

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.
