• Interpreters can pause translation during breaks
• Background conversations remain private

This function is particularly useful during translation pauses or short interpreter breaks.

Even in crowded or noisy environments, participants can easily adjust the volume for clear listening.

This allows connection to external audio sources such as:

• Church PA system sound boards
• Audio mixers
• Media players
• Audio playback devices

Note: The AUX and microphone share the same input jack, so background music and microphone input cannot be used simultaneously.
