Using the in-flight adapter
If you are using the in-flight entertainment (IFE) system of your air-
line, the audio from the IFE may be interrupted by important
announcements via the aircraft's public address (PA) system. In most
cases, the announcements are much louder than the audio from the
IFE. The PXC 550-II detects this and suppresses the volume jump
that occurs when there is a switch between PA and IFE system.
The volume of the headphones remains at a low level even after the
announcement via the PA system. If you want to increase the volume,
adjust it on the IFE system.
Connecting the headphones using the
USB cable
When you connect the headphones to a Mac/PC/mobile device
using the supplied USB cable, you can play audio content from your
Mac/PC/mobile device directly through the headphones.
