OK, last question.
With the back of the unit facing up, and the open battery compartment toward me, battery compartment open and
the bass filter switch at the back of the compartment,, which position engages it, left or right?
I've tried monitoring through earbuds, but don't have a pair with sufficient low frequency response to be sure. I've also tried recording
some test tone sweeps played through my stereo, but my speakers roll off below40hz
so ... again, it's not very obvious.
This was a much more noticeable thing with omnidirectional mics (CSB's), which had an uncanny
ability to pick up distant traffic rumble, car stereo bass from several blocks away, etc.
Using Cards (AT853's) now, they are much less susseptible to this.
