Max,

I don't know this mic and haven't used an LS-10 so I'll be brief.

The mic has an unbalanced output which means one wire is connected to
ground. Make sure you don't have phantom power on as this will put 48V
across the input as it is no longer "phantom". Phantom power is 48V applied=

equally to both input wires with respect to ground.

To make the mic "balanced" or "floating" which would isolate the signal
wires from ground, you would need a mic transformer in circuit. Balanced
means equal plus and minus inputs and floating means these inputs have no
connection with ground.

One way to check it out would be to wire the mic with loose lesds or
whatever into the live inputs without a ground connection. You will get hum=

and interference but it may give a clue to whether a transcformer would
help.
