Language Channels :

Using the language channels, when I do consecutive translation : Sentence by sentence : There is a presenter in the main room and one translator X who does sentence by sentence translation (cosecutive). also in the main room. P is heard in the language channels with less volume. X should not be heared in the language channels as while X translates in the main room, the others should do the translation in the translation channels. How can I put that up so that X is not heared in the language channels?
