3D
Holographic+®
for
Speakers
(30°+/+/
- )
The latest 3D Holographic+®matrix
for
Speakers offers
something
quite
special;
it
takes high-end systems
to
another level
of
performance.
It
was drawn from
the
original ground-breaking
work
by
Alan Blumlein,
the
'father
of
stereo.'
First,
it
corrects
the
fundamental spatial distortion in
recordings. Second,
it
increases
the
width
of
the
soundstage beyond
that
of
the
speaker placement.
30°+ This matrix adds an extra
30°
to
redress
the
narrowplacement
of
speakers (eg eitherside
of
a
PC
monitor).
+
3D+®matrix
is
switched
out
of
the
signal path.
This matrix recreates original
'width'
of
the
soundstage and
is
the
recommended
DEFAULT
setting.
