Metallic sound when recording broadcast

[ana.ferreira]

Hello there!
Does anyone know what i might be doing wrong when recording my broadcast? The recording gets this metallic or waterly sound in the end! It's difficult to use pre-recorded shows under such conditions. Why does this happen? Can someone, please, help me?
Thank you
