Phase
Adjustment·
0°/90°/180°/270°
This control allows
you
to
change the phase of the subwoofer's output signal
to
correct
for
any
possible mismatch and resulting cancellation between the subwoofer and your main
speakers/amplifier.
To
adjust, simply listen
to
the system with music playing, then depress the
various phase switches
on
the remote control and listen
for
a change
in
mid-bass frequency
output. The
correct
position will have a
greater
amount of apparent mid-bass frequency output.
If
the settings sound similar, we recommend the "0" position.
See
the remote control section
for
more
information.

Function
The subwoofer will
turn
itself
on
automatically when
an
audio signal is present. If
no
signal is
present
for
approximately eight minutes, the unit will switch
to
standby mode (blank
LED).
While
in
standby mode, your subwoofer will draw very minimal power. Your sub is shipped
in
the "INACTIVE" (always
on)
position.
In
order
to
activate the circuit, change the switch
to
"ACTIVE".
Warning:
If the Sub-Out channel signal level from your receiver
is
too
weak,
this feature will
not
operate
properly and
shut
the subwoofer
off
while
you
are listening to
it.
To
correct
this, see the
VOLUME
CONTROL
section on previous page.
