troubleshooting

I have two Wharfedale Titan Sub-A15's and they no longer work due to an unknown issue. Does anyone know whether these subs are reliable? Any way to troubleshoot?

Hey guys, instead of calling it bad luck, I'm calling it an opportunity to learn.

I scooped one of those "beginner all in one" guitar / amp kits a couple days ago, where the whole thing is in a box, with picks etc etc. It's a first act brand and was $85 total.

I owned this reel-to-reel machine from when I purchased it new years ago. I want to restore it.
One issue I'm having is when playing back recordings I'm not getting audio out of track one. The VU meter shows audio is present. Other tracks are fine.
If anyone can provide some tips to for finding the root cause of failure that would be appreciated.
Thanks,
Paul

Hi friends!

Bought a used Korg MS2000. Half the programs works fine, but in half of the programs most of the keys are silent. Any suggestions?

We removed the Master section of Mackie 32x8 board for cleaning. There are two 7 pin (Power?) connectors that are interchangable and I managed to reverse them. Now, of course, the mixer does not work. Lights on the channel strips are on but the Master Section is dark. Any ideas what can be done to repair the mixer or at least start troubleshooting?

I have 2 Firestudio Projects hooked up to Behrskhg98y4winger powered speakers. Recently, the overall volume has significally decreased in the left channel. I am ruling out the monitors, because it affects the headphone outputs too. I messed around in the Universal Control settings, Windows Settings, Sonar settings, and ASIO settings.

Not sure where to turn to next.

So, I have been working over the past couple of years intermittently trying to record both my guitar, and lately my voice, using my laptop and audio interfaces. I have always run into the same problem: background hiss and white noise.

I recently upgraded to an RME Babyface. For some reason I can't hear anything when I do a FILE > IMPORT > then select a sound to preview. I can see it is playing but I hear no sound. I have to import it to the timeline before I can even hear it. Where is the preview sound usually routed?

Just recently developed some subtle, yet ultimately crippling hum problems.
