Possible Problem with a New EXP II

[Clifford Powell]

I have an EXP II that I bought about 1 month ago. I have been using the stock Koss headphones. The lowest I could hear my threshold was 9 where I have read many posts where folks set it at 7. I'm dead at 8. So I bought a pair of new Sun Ray headphones thinking that might solve the problem. Nope. Had a friend see if they could hear the threshold at 8 or lower - zero for them too.

Settings are:
Volume - max
Sounds - ferrous, Audio 1 (same with normal)
Gain - 7
Headphone volume - max - stereo
Deep - tried both on and off (why this might make a difference I haven't a clue)

Could this be a calibration problem with my EXP II - possibly it's a flaw with the machine itself? Could my 9 equal everyone else's 7?

Any ideas?

If I need to call Minelab what is the procedure and who do I call?

TIA

Mine drops out at the same place as yours. The key to the threshold is the slightest sound YOU can hear and not if it drops out at 7 or 8.

Cliff....It's really no problem. As you correctly surmised, it is probably a matter of 'tolerance' in components (or an internal setting). It shouldn't effect your machines functionality. As long as you can set it to an acceptable threshold level, then everything is OK. Cody's post seems to confirm this. My machine comes in at 8, so there you have a general idea of the spread of this function.
It all relative............MattR.UK.

p.s. Good morning Cody....Hope you and yours, are all well.
