Hi Chris
At the risk of repeating what others have said, there are two types of adap=
ter for attaching a 3-pin XLR (balanced) microphone to a recorder with a 3.=
5mm stereo (unbalanced) input. They look identical but are wired differentl=
y. One is meant for attaching a stereo XLR microphone and the other is for =
attaching a mono XLR microphone. You want the mono one. Generally the cable=
description will say "wired for dual mono."
The Hosa XVM-102F is one example of the type of "dual mono" cable you are l=
ooking for.
Another type of adapter uses a transformer to convert the balanced signal f=
rom the microphone to unbalanced for the recorder. This also raises the imp=
edance, which is not ideal for some recorders, the LS-11 being one of those=
.
Nevertheless, I have had good results using the Hosa MIT-156 with the LS-11=
. I get more gain using this transformer type than with the simple XLR-3.5m=
m cable, I think because it is using both sides of the balanced signal rath=
er than simply dropping one side to unbalance the signal. Sorry if that's m=
ore information than you want!
You could buy both and try them and keep the one that works best for you, o=
r keep the other on hand as a backup. These cables are not as robust in the=
field as I would like. I have repaired mine a couple of times.
With Hosa cables, if you unscrew the 3.5mm connector, you might find that t=
he two metal tabs that are supposed to fold down and hold the cable wires i=
n place are not folded down. This puts extra strain on the solder points. F=
old those down with a pair of pliers and the cable will last much longer.
