Mackie HD1521 - cutting out and then pulsing with thermal lights on

Hi there, I have had a pair of Mackie HD1521 for a few years now and at a party last weekend one of my speakers ceased to play - with the thermal like coming on. When I tested the speaker at home, I heard a pulsing sound beating through the speaker - but no music playing through. Also, when the speaker was switched off - the lights on the back stayed on for a good 15 - 20 seconds. Can anyone please help me diagnose this / recommend a solution? Thanks Steve

SOURCE: logitech speakers will only play on 2 speakers not 5

Liamog, i bought the exact same speakers and sound card, and i had the exact same problem as you. I tried for days to fix it and it turns out that its only a setting you have to enable in your sound card settigns. If you go into your EAX console for your creative sound card you will find a thing that sams CMSS 3D, and all you have to do is select the button that says Enable CMSS 3d surround. I hope this will fix your problem. Alex.

SOURCE: Wharfedale 9.5 Diamond Front Speaker

you have a poor connection somewhere in your signal path. This sort f problem could be anywhere from inside the speaker box to the output stages of the amp. speaker protection relay in the amp, or even a noisy vol control or dry solder joints in the output stages of the amp. eliminate anything external to the amp by swapping right for left and test, spray the speaker protection relay in the amp with 2-26 or burnish the contacts with a piece of white business card cut to fit into the contacts. You will see deposits on the card that you have cleaned from the contacts. Carefully inspect the soldering about the output stages(heatsink area) and re-solder any poor or cracked solder joints. Good luck... these are the most common problems. I can go further in if the problem remains after you have done this. Good luck

SOURCE: sound from 4 speakers cut off..

To troubleshoot a speaker system where sound is not issuing from all speakers, please do the following:

  1. Verify that all cables are plugged in correctly. Make sure the rear and/or center/sub audio cable is plugged in to the correct port. On most surround sound cards, the rear audio port is black, the front audio port is green, and the center/sub audio port is orange. If you do not have a surround sound card, make sure you obtain the proper adapter (discussed in the next paragraph) or use surround sound emulation if your speaker system offers it. If you are not sure if you have a surround sound card, please check with the manufacturer of your sound card for details.
  2. Make sure your sound card supports the same amount of channels as your speaker system contains. For 4.1 systems, it should have a front and rear speaker jack on the card. For 5.1 systems, the card should have a front, rear, and center/sub, output. The card should be properly installed and configured. Please contact your sound card manufacturer for details. If you do not have a surround sound capable sound card, you can use the source selector switch or the M3D button on the controller unit (if available). You can also use an adapter to split the signal for the front and rear speakers. This type of adapter is a 3.5mm male to 2-3.5mm female jacks. You can purchase this adapter at your local electronic store. Please refer to your manual if you do not know if your speaker system can emulate surround sound.
  3. Try connecting the speakers to a portable sound device such as a walkman or portable CD player. Plug the speakers into the headphone jack, but make sure the volume is lowered so the speakers are not over powered. You can do this for both the front, rear, center/sub speakers to verify that they work. If the speaker system works on the walkman, then you are experiencing a configuration issue with your sound card. Please contact your sound card manufacturer.
  4. Check the system Volume Control located in the System tray. Make sure that the volumes are at a reasonable level and are not checked for Muting.

SRM 450 Mackie

1)Clean the heat sinks on the amp on the back of the speaker,
2) carefully remove the amp from the rear of the cabinet and look for 'crispy critters' on the circuit board. If you see 'um, either take the amp to a service center, or go to your dealer and get him to order you a new one.
3) if you're goin' thermal, either get higher powered speakers, or tune it back a bit with these. I have a set that has run years in a dance room with no problems. If you are stretching the system to cover a bigger audience, think about another pair.
