I assume you're talking about a valve mic or similar.

In the vast majority of cases, the audio output is provided via a transformer, and that is immune to correctly wired phantom power.

So the short answer is: No, it's not necessary to switch phantom power off.

but the slightly longer answer is that it is probably good practice to do so...
