AudioSource SW TWO Owner's Manual page 4

Using
the
Controls
Power:
The power
control has three positions:
On,
Off,
and
Auto.
The Auto
position
is
the
normal
setting.
This keeps
the
subwoofer
amplifier in a
standby
mode. Using
sophisticated signal sensing
circuitry,
the
S
W
Two
amplifier
is
instantaneously activated
whenever
a signal
is
detected
at
either
of
the inputs. If
no
signal
is
detected
over a period of minutes, the amplifier switches
back
to the
standby
mode. The
On
and Off
positions
override
this circuit, setting
the
SW
Two
permanently
On
or
permanently
Off.
The
red "Power"
LED
indicates
when
the
SW
Two
is
On.
Phase:
The normal
setting for the
Phase
switch
is
the
0
s
position.
Because
the
SW
Two
is
not
in the
same
cabinet or the
same
location as
your
other speakers, the
sound from
the
SW
Two
may
arrive
at
your
ears
at
a slightly different
time than
the
sound from your
other speakers
-
it
may
arrive "out
of phase". In these
rare
cases, there will
be a
cancelling effect in
the
upper
bass
and lower midrange
.
The
bass
sounds
will
appear
somewhat hollow and
the level control
may
seem
to
have
little
or
no
effect.
Setting the
phase switch
to
the
180
Q
position will
compensate
for these
effects.
Let your
ears
decide
which
setting
sounds
best.
Level:
The
S
W
Two
will
be playing along with the other speakers in
your
system.
The
level control will
allow
you
to
balance
the
volume
of
the
S
W
Two
to
blend
in
with your
system.
Once
this
level control
is set, it
should
not require
further adjustment.
The volume
of the signal
coming
into the
SW
Two
will
determine
the
listening
volume.
Start
with the level control
all
the
way
down. Then, with
the
other speakers playing, slowly
increase the level
of
the
SW
Two
to
the desired
level.
The
sound where you normally
listen to
your system
may
be
different
than the
sound
at
the
SW
Two
while
you
are
making
this
adjustment.
It
might
take a
few
rounds of stepping
back and
listening to get the level set correctly.
Crossover Frequency:
The
crossover acts as
an audio prism, separating
sounds of
different frequencies
from
each
other.
The
crossover frequency control
is
used
to
adjust
at
what
point the crossover will separate the
low
frequencies
being used
by
the
subwoofer from
the
high frequencies continuing
on
to the rest
of
the
System.
The
normal
range for
this
control will
be between 80
Hz
to
120 Hz. Raising
the
crossover frequency will increase the
range of sounds
the
SW
Two
will reproduce.
Lowering
the
crossover frequency
will limit the
range of
frequencies
reproduced by
the
SW
Two.
