Source selects which source you want to use.
If you're using a PC for 3D positional gaming, or a surround sound decoder for home
•
cinema, select source 1.
If you're using a full-size unit, such as a CD player, select source 2.
•
If you're using a line-level device that has a 3.5mm jack output, such as a portable CD
•
or MiniDisc player, select Source 3.
Source 3 is connected via the socket at the front of the
amplifier. Use this for any line-level device that uses a
3.5mm jack, such as a portable CD or MiniDisc player.
For the stereo sources (2 and 3), the Quad
switch duplicates the signal from the front
speakers to the rear speakers, so that you
can hear stereo surround through two sets
of stereo speakers.

This is where you plug in
your headphones. When
you insert the
headphone jack, the
speakers are muted. Note
that, if you are using
headphones, you should
set the 3D positional
sound algorithm on your
sound card for
headphones.
