Technical specifications
Volume
increases or decreases
the volume produced by Sirocco
Crossfire.
Sub
increases or decreases
the volume produced by the
subwoofer.
Fade
balances the sound between the
front and rear speakers. Turn it anti-
clockwise to fade to the rear, clockwise
to fade to the front.
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.
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.
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.
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.
