Mbox2 Inputs Run Hot!!!!!!!?????
 

Hi, just got a brand new mbox 2 running it on a brand new iMAC 21.5 but virtually every 2nd time i turn on the mac/mbox and arm an audio track in pro tools for recording the signal is continuously peaking (with a bizarre white noise hissing coming through the monitors) nothing even has to be plugged into the inputs! nothing fixes it unless i unplug it and plug it back in???? whats going on??? any help would be greatly appreciated as this is one of many problems im have with my brand new system and im pulling my hair out! thanks guys

what version of protools and OSX are you running?

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

This happens to me too every now and then. Launch Pro Tools, record arm a track -- then BAM constant hiss that peaks the meter. Doesn't matter what the input is, can be mic or line in. Have to reboot and then it seems okay... until the next time it happens a few days later...

Mackbook Pro
OSX 10.6.3
Mbox 2 mini
PT 8.0.3

If it's not that, then it's a kernel panic from using sleep mode...

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

Sleep mode is not compatible with Pro Tools. This is outlined in the user manual.

10.6.3 also has not been qualified for use with PT, yet. I would, however, recommend trying the 8.0.3cs2 update and see what happens. Was this apparent before you upgraded to 10.6.3?

im running pro tools 8.0.3 and osx 10.6.3...is it a possible problem with osx do you think? or is it more likely to be an unfortunate mbox hardware issue?

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

The Windows community was having significant issues with white noise recently. While OSX may be the culprit in this case, I would recommend you upgrade to 8.0.3cs2 and see if this still happens.

ok will try it tonight and let you know thanks alot : )

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

I didn't see that in the manual but I basically figured out on my own that sleep mode seems to have the same effect as hot-swapping the Mbox2 (kernel panic).

I've had the "hot input" problem for a while now... I don't even remember when OSX 10.6.3 came out so I'm not certain if the problem was around before that. At any rate I just updated from 8.0.3 to 8.0.3cs2 this morning, and I'll let you know if that changes anything over the next few days.

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

So after updating to 8.0.3cs2 I haven't had a single kernel panic. Either from going into sleep mode or from hot swapping or the inputs pinning the meters when I record-arm a track (knock on wood?).

Hopefully that means this is the end of it...

Re: Mbox2 Inputs Run Hot!!!!!!!?????
 

Okay well it turns out I'm still having the overloaded inputs problem. Hot-swapping kernel panics seem to have been fixed, however.

Not sure if this has been fixed for the OP but it seems the hot-input thing is still an issue
