MOTU 8282mk3 FW LOUD POPS!

[TheoKontonis]

Hey guys!

This is my first post on MOTUnation!

Before four months I experienced a problem. While I was working on a project on Cubase Pro 8.5.5, suddenly I heard a LOUD POP from my monitors (Yamaha HS-50M) my MOTU 828mk3 FW immediately disconnected from MOTU Audio Setup and from Cubase and got burnt! I contacted MOTU Tech Support and got it repaired through its distributor here in Athens. Since that fact, my 828mk3 works fine but this LOUD POP persists! I hear it one to two times per day. Its frequency is random and it bothers me a lot. Since that I am in frequent contact with MOTU Tech Support and we can not find a solution! Could help me please? I do not know what causes this POP.

Do you have other interfaces on the same system?

That pop used to happen to me - it was from the system sync becoming unstable.

If you are using Firewire, switch to using USB instead. Once I did that my problems disappeared. Perhaps the connection is flaky with the Firewire cables they make us use (the 9-pin ones).

Hi Terry!

Thanks for your reply!

No, I am not using other interfaces on the same computer!

My 828mk3 is the FireWire model unfortunately and it lacks USB.

Today for example, it did not appeared...

Should I buy a power conditioner and have all my equipment attached on it?

Theodore.

YES! Especially if your AC supply is not solid!

A power conditioner would offer another layer of stability, for sure.

When I would use DeOxit cleaner on the Firewire ends and connectors, that often would make the problem go away for several days - even two weeks once. Also buying new cables would help. That is why I wonder if the connection is simply not very stable on Firewire cables. But I finally gave up fighting it and went with the USB, even though I was enjoying stacking two units for the inputs by daisy-chaining them for a while. But even used singly, the darn things would never be reliable with the Firewire. I hope you find a solution - I'd be keen to hear what you discover!

(I still have a ton of Firewire cables here!!!)

Hi guys!

Thank you very much for your replies!

You helped me a lot!

Currently I am saving money to get a power conditioner!

I will try electrical contact cleaning, alternate cabling and report back soon!

Firewire has always been rock solid for me on an 828mkII. Advantage: lower CPU hit than USB.

Hi guys,

Lest has to do with my FireWire cable that is wrapped in order to be tidy?

Anyway, I am looking for a physical shop to get a Firewire 400/800 cable.

Nice to hear this Marcus!

Hi guys!

Today I bought a new FireWire 400/800 cable and connected the interface with the computer with it. For ten minutes now everything is fine!

[terrybritton]

Here's hoping with you that the new cable does the trick!

Hi Terry!

Thank you my friend!

Hey guys!

May I have your attention please?

I tried and changed my old FW cable with a new one. With the a new cable I was fine for two days. After these two days passed the clicks and pops came back. Then I tried and connected to my wall outlet an external outlet that filters the AC current and to this outlet I connect a multi outlet that in this going all my equipment. Again for two days I was fine. After those two days the clicks and pops are back again...

What should I do?


Thanks in advance!

Hey guys!

I tested with a FireWire to ThunderBolt adapter but I didn't find any luck...

[terrybritton]

Does this happen anywhere you might be? Or have all these tests been done in a single location?

The reason I ask is that power brownouts can also cause this to happen (pops, squeals, whistles) from the box losing sync due to a power fluctuation. The only cure is either be in a different location or use a power conditioner if that is the cause.
