A SM58-type mic is about the last thing you would want for this
application.
It is a low output, low impedance mic designed for close micing.
You want a high output mic, and since your hands are probably busy, you
want
something that will pick up pretty well from a distance of like 6 inches
or
more.
Ordinarly I'd recommend a condenser mic, but since this is a cheap mixer,
it
doesn't have phantom power.
I'm mystified as to why the matching transformer didn't help. It should be
the bomb. Is it blown?
Plan B would be to get a mic preamp like a Rolls MP-13. Hey, it might even
cost you as much as you paid for the mixer... Now you know why the mixer
was so cheap!
Plan C would be to find a high output dynamic mic. I haven't even thought
about stuff like that for about 20 years... Most of it is cheap garbage.
Thing is, that matching transformer should turn a SM58 type mic into a
high
output mic. So I'm really mystified why that matching transformer didn't
work. Got another one to try?
