Channel or Tape out is mono

[jaebaeli]

i need some insight from some of you Tascam gurus.
I think my Tascam 424III has a channel or tape out issue which might need repair from a techician but i want to be sure i've isolated the problem correctly.

I use Audiograbber and Audacity for my software when mixing down to PC. I noticed lots of sound problems, like something was missing, and then i saw that the secondary window in audacity showed the 2nd channel/track was flatlined. I tested with other recordings to be sure and my monitor speakers work on other songs (in stereo) and the sound waves show in the second window.

So i checked to be sure i didn't mix out with a mono switch on, and i didn't. I also made sure to try different panning positions--even up the middle, and it still flatlined... so i guess there's an issue with my tape out plugs? Or channels? is there any other thing that could cause this, or am i headed for a Tascam techical repairperson?
Appreciate any help.
Jae

If you have a conventional set of headphones and a stereo system you can plug your 424 into that to test if its outs are being sent correctly and cleanly, two channel at a time through the tape outs or all four channels if you use the stereo outs as if you were doing a conventional mixdown.

If it does, then the problem lays somewhere in your computer setup.

Also check with a different set of patch cords to make sure that your not dealing with a simple bad cable or plug on your wire.

Cheers!

I'm no guru, but I have a 424 mkIII and mixdown to digital regularly.

I'm not understanding your situation.

You are using your TAPE OUT jacks on the 424? Instead of LINE OUT? That is cool, but it means your soundcard or digital interface can handle 4 inputs at once and direct them to seperate digital tracks. And only one of the four (#2) is flat-lined?

Or did you mean that one of your LINE OUT jacks is not working? If so, that is an easy fix.
