What setting should the phone channel be on to air a call?

• A. Mix with auxiliary
• B. Program
• C. Monitor
• D. Production

Answer: (B)

To air a call, the phone channel should be set to the program setting. This is because the program setting directly routes the audio from the phone channel to the broadcast output, making it audible to the audience. When on the program setting, any call received will be mixed and sent out live, ensuring that listeners can hear the conversation clearly.

The other settings serve different purposes. For example, monitor allows the operator to listen to the call without it being aired, which is useful for evaluating call quality but does not enable the audience to hear it. Mix with auxiliary is typically used for combining different audio sources but would not ensure that the phone call is broadcasted. Production is likely more focused on the creation and editing of content rather than live broadcasting, so it wouldn't be the appropriate choice either. Thus, for airing a call, program is definitively the correct setting to use.
