Interconnections
with the CINCH RCA connectors
Connections to the LINE IN
If your preamplifier or your integrated amplifier is fitted with a
stereo low-level output, then connect its L (left) and R (right)
outputs to the L (left) and R (right) LINE IN
woofer. If your amplifier offers a one mono output, connect it to
either the L (left) or the R (right) subwoofer LINE IN
Connections from the LINE OUT
The signal from the L (left) and R (right) LINE OUT
the one being brought in by the L (left) and R (right) LINE IN
connectors. These outputs can thus be used to bring the signal
to the amplifier powering the main loudspeaker.
Interconnections with the speaker terminals
Connections to the HI LEVEL INPUT
If the preamp section of your Hi-Fi or audio-video system is not
fitted with a lowlevel output, you should then connect the sub-
woofer by using its loudspeaker terminals. When connecting
the L (left) and R (right) speaker outputs of your amplifier to the
5
HI LEVEL INPUT
plugs of the subwoofer, be careful not to
cross (-) and (+) cord of either L (left) or R (right) channel. Such
a phase inversion might damage your main amplifier.
Connections from the HI LEVEL OUTPUT
These outputs can be used to bring the signal to the main loud-
speaker systems or to a second subwoofer in a parallel mono
configuration. In the last lay-out, the L (left) and R (right) HI

terminals must be connected to the L (left)

fer. The input signal must then arrive into the first subwoofer by
its L (left) and R (right) HI LEVEL INPUT
signal from the L (left) and R (right) HI LEVEL OUTPUT
plugs is the one being brought in by the HI LEVEL INPUT
connectors. These outputs can thus be used to bring the signal
to the main loudspeaker systems.
Power supply
3
The AC IN
cord must be connected to the mains to supply
the subwoofer. The selection of the right voltage 115 V - 230 V
is done with the selector 150 V - 230 V
on AUTO or ON. With the switch on the AUTO position, the unit
will mute after a few minutes without input signal. The system
turns on automatically when signal comes back. Attention, befo-
re operating the unit, be sure that the operating voltage of your
unit is identical with that of your local power voltage.
ADJUSTMENTS
0
LEVEL
For a first volume adjustment, position the CROSSOVER FRE-
9
QUENCY
at around 120 Hz, and turn slowly the volume
0
LEVEL
clockwise from minimum level up to a position whe-
re you feel that the subwoofer sound level is appropriate. A
check of the level adjustment will be necessary after following
steps.
CROSSOVER FREQUENCY
This potentiometer adjusts the cut-off frequency which determines
the working bandwidth of the subwoofer. This adjustment should
be done according to the specifications of the main speakers and
the room acoustics. Choose the best frequency after various lis-
tening tests.

PHASE
For a better sound integration of the subwoofer in the main sys-
-
tem, the PHASE
of the subwoofer might have to be inver-
ted (180° position), depending on the distance between the sub-
woofer and the main speakers. You have to check the PHASE
each time you move your speakers and each time you adjust the

CROSSOVER FREQUENCY
. Attention, if you use 2 sub-
woofers, both phase switches must be on the same position.
