Narrative:

I released a flight with a no-go MEL for the megaphone. It states in the MEL manual that there are 2 installed and 2 required for dispatch. The captain and first officer also missed it. The MEL also stated that it can be applied if only baggage and cargo are carried. I will remember this MEL. Both the captain and dispatcher did not realize that there were 2 megaphones required for dispatch.
