Logitech Squeezebox Boom - Manual (Page 9)

8 Logitech®
Back Panel Connectors
A. Line in. Ideal for connecting an MP3 player, portable CD player, or other
audio device with a 3.5mm line level output and enjoying Squeezebox
Boom’s advance driver design and acoustics. It’s not necessary to
select Line In as a source from the front panel; Squeezebox Boom will
automatically detect the connection of your device.
B. Headphone or subwoofer out. Connect headphones for private
listening, or a powered subwoofer to add bass reinforcement. Since this
is a dual-purpose connector, you must select Settings > Audio > Line Out
from the Home Screen to select headphone or subwoofer output. If you
are using headphones and the audio comes from only one channel, check
to make sure that the subwoofer setting is not selected.
C. Ethernet. If you prefer to use an ethernet connection rather than
Squeezebox Boom’s built-in wireless, you can use your own ethernet
cable to connect Squeezebox Boom to your network.
D. Power. Be sure to use only the power supply provided with Squeezebox
Boom.
