I don't need to measure the frequency or voltage, only check the
waveform for distortion without blowing my CRO.

Pray tell where the heck would you even GET 1KV (or larger) audio
signals????
And hypothetically speaking, if you had such a source, would you be
so ignorant or s*d to connect it to the scope?

Obviously not, hence the question. Dumbass.
