Which one is correct:
1) She introduced him through a microphone.
2) She introduced him over a microphone.
What is the correct preposition used before the word 'microphone'?
Enlighten me on this. Thank you.
Thanks for your explanation.
Would "on" be acceptable too?
She introduced him on a microphone.
Please note that I'm not a teacher.
It's not completely impossible but it doesn't sound natural after "introduced".
He's on the mike now, I'll ask him to introduce you.
She was on the mike for hours. I nearly fell asleep!
On/off can be used as part of a couple of phrasal verbs too:
Get on the mike, it's your turn to speak.
Get off the mike, it's someone else's turn.
