b
Audio input port (Audio In)
— Connect an MP3 player or other audio device to this
3.5 mm TRS jack for auxiliary audio line input. When a device is plugged into this port,
its audio is mixed with either the internal microphone or any external microphone
connected to the Mic jack (
a
).
NOTE:
Because the audio input is mixed with the microphone, pressing the
Volume button on the microphone affects the volume of the audio input
device. However, it is recommended that you use the volume control of
the input device instead of the microphone Volume button to adjust the
levels of this audio input.
