Hi guys,

I ran into some very old mic's and I want to find out if they are worth
using, and for what.
They a
- DM7500 ( it looks like a shure sm58, but quite a lot older) no more
info available.
- ARIA UMC 7103 (600 ohms cardoid electret)
- philips LBD 9100/05 ( and 8900 910 00501, but that is I think a
serial nr)

I googled around and all three come up with no useful info.

Do you have any specs on this?

Thanks for your reply,
Erik spirit

The only spec that matters is what they sound like. Try, and let us
know
