MOTM

i am considering several panel meter possibilities and i could use some 
help. if i integrate, say a 10volt DC voltage meter into my MOTM system, 
what will happen if:
A. i plug an AC/audio signal of, say +/-5v, into it?
B. a CV/audio signal exceeds the 10 volts? i would guess that the meter 
will become pinned, but not harmed.

would i be better off with a VU meter for audio and a DC meter for CVs?
any help is appreciated!
thanks
