AUTO
ON/OFF
This function automatically turns
the
subwoofer
on and off. The default setting
is
auto
on, which
is
in
a power-saving
standby
mode
that
continuously monitors
the
inputs for any signals. The
LED
glows
in a very dimly. When a bass signal
is
detected
through
the
RCA input,
power
is
automatically
turned
on with
the
LED
indicator
glows
brightly. If
no
bass signal
is
detected
within a
15
minute period,
the
subwoofer
will return
to
standby
mode.
Sensitivity
of
the
auto-on function ("AUTO ON THRESHOLD") can be set from 1-
10
mV. The correct sensitivity
depends
on
the
pre-amp/amplifier used but a value
between
3 and 6
is
generally
suitable.
If
AUTO ON/OFF
is
deactivated,
the
subwoofer
will be
turned
on
permanently
without
a stand-by mode.
PARAMETRIC EQUALIZER
The parametric equalizer gives you
the
ability
to
adjust
the
audio
output
(within
the
subwoofer
range)
for
your
preference. The app lets you choose and adjust
the
center
frequency, bandwidth, and gain.
The adjustments also enable attenuation and often eliminates unwanted reso-
nance. To reduce unpleasant resonance, identify
the
frequency
causing it
by
using
a
test
disc with
test
tones in
the
bass
frequency
range. Start
by
playing
the
bass
notes
in sequence. When a bass
note
sounds unnaturally loud, this is
the
room
resonance
that
you can
"dampen"
with
the
help
of
the
equalizer. To
do
this, set
the
CENTRAL FREQUENCY control
to
the
frequency
determined
by
the
test
disc.
Select a "NARROW"
bandwidth
and reduce
the
GAIN control until
the
bass
note
is
reproduced
with
the
same
apparent
loudness
as
the
other
frequencies. To selec-
tively
boost
a particular
frequency
range, you should increase
the
bandwidth
slightly (move
the
control
towards
"WIDE") and then slowly adjust
the
GAIN, avoid-
ing any unnatural
"droning"
effects.
DELAY
The "DELAY" parameter enables you
to
delay playback
of
the
subwoofer
audio
signal. This feature
is
particularly helpful
when
the
subwoofer
is
placed in ex-
tremely
close proximity
to
the
listening position
compared
with
the
rest
of
your
speakers. Increasing
the
delay
time
by
1 millisecond ("msec") will have
the
same
effect
as
moving
the
subwoofer
approximately
13
inches (33
em)
further away from
the
listening position. Consequently, a setting
of
20
milliseconds
would
be equiva-
lent
to
increasing this distance
by
approximately
21.5
feet
(6.6 meters). If you are
using a surround-sound receiver
or
amplifier
equipped
with
an
automatic calibra-
tion function, its
LFE
output
signal will automatically set
the
delay
time internally so
delay
on
the
subwoofer
should
be
set
to
minimum.
