I'm not sure what to make of this. I wonder how the two compare, and
which might be the better value for the money.

One seller:
http://www.sjtelecommunications.com/ast-636l.html
carries both and, I think for the same price.

Any thoughts? Thanks.

A 636L is a communications mike and a 631L is for paging?
That would mean different response curves. Figure a 636L
is good for 300-2500 Hz and a 631L to have more response.

A bit more reading shows the 636L to have radio connections;
(6 wire cord which allows for relay, electronic or virtually any type hook up),
and the 631L to be for paging with balanced output;
(4-conducter, 2-shielded)

Your radio only responds to the communications curve.
Lots of lows will distort early and lots of highs will splatter.

Get the 636L. I'll send you my bill for the consultation!
