PHASE (
0
°
- 180
°)
The
PHASE switch
can be used to invert the phase of
the output signal, i.e. turn it through
180°
compared to
the input signal.
The
PHASE adjustor
provides fine-tuning of phase over
the range
+90°
. . .
-90°
.
Notes:
It may be advantageous to change the phase, depending
on the position of the sub-woofer. We suggest that you
adjust the settings until you obtain the most pleasing
subjective impression in the bass / mid-range area.
CUTOFF FREQUENCY
This adjustor is used to adjust the separation frequency
between sub-woofer and satellite loudspeakers. The
larger the satellite speakers, the lower the separation
frequency that should be set.
Set the separation frequency to the lowest point
commensurate with the frequency response of the
satellite speakers, otherwise the physical location of the
sub-woofer may become apparent when listening.
Note:
This switch is only effective if the filter is switched on, i.e.
the
FILTER
switch
must be at the
'CTRL / FILTER ON'
position.
POSITION
This switch adjusts the bottom limit frequency and the
level of the sub-woofer to suit the speaker's location in
the listening room.
•
Select the
'CORNER'
setting for a corner location.
•
Select the
'FREE'
if the speaker is standing freely in
the room.
•
Select the
'WALL'
if the speaker is located close to a
wall.
CTRL / FILTER ON / FILTER OFF
The purpose of this switch is to switch the internal
crossover on and off.
If the sub-woofer is connected to the sub-woofer output
of a surround decoder which features an integral cross-
over unit, the switch should be set to
'FILTER OFF'
.
If the sub-woofer is operated with a signal source which
does not feature an integral filter (normal stereo system),
the switch must be set to
'CTRL / FILTER ON'
.
If you wish to be able to switch the internal filters via the
-
SC
LINK
facility, the
Filter
switch must be set to the
'CTRL / FILTER ON'
position.
LED on the sub-woofer front panel
LED glows red:
The sub-woofer is in stand-by mode, and is switched on
automatically when a music or control signal is received.
Note:
The subwoofer will automatically switch to STANDBY
when the trigger voltage goes low (CTRL mode) or
approx. 60min after the music signal ends (AUTO mode).
LED glows green:
The active unit is operating.
LED flashes red:
The output stage has switched itself off due to over-
loading or overheating (PROTECTION). Please lower the
volume. After a while the sub-woofer will switch itself
back on automatically, at which point the LED stops
flashing.
LED flashes red (fast):
The subwoofer has switched itself off due to excessive
overheating. To switch on the subwoofer again, switch
off the mains switch and let the subwoofer cool down
completely. After cooling down switch the subwoofer on
again. If the LED still keeps on flashing red, the
protection circuit has detected an internal fault. Please
contact your
dealer to have the subwoofer checked
in this case.
LED flashes green:
Power-on delay running. The sub-woofer signal is only
reproduced when the delay period has elapsed!
