helped. Even making sure that the 1/4" adapter on the 1/8" tip of my headph=

pleasant to listen at in the first place.

you're recording at the time of capture unless you monitor what you're rec=

it was a military aircraft carrier at sea, it might not be there anymore. =
And you'll never be able to replicate the problem. And always wonder what t=

the problem on site and get a flawless recording.
