Interconnections
with the CINCH RCA connectors
Connections to the LINE IN
7
connectors
If your preamplifier or your integrated amplifier is fitted with a
stereo low-level output, then connect its L (left) and R (right) out-
puts to the L (left) and R (right) LINE IN
7
inputs of the sub-
woofer.
If your amplifier offers a one mono output, connect it to either
the L (left) or the R (right) subwoofer LINE IN
7
inputs.
Connections from the LINE OUT
6
connectors
The signal from the L (left) and R (right) LINE OUT
6
plugs is
the one being brought in by the L (left) and R (right) LINE IN
connectors filtered at 80 Hz.
These outputs can thus be used to bring the signal to the ampli-
fier powering the main loudspeaker.
Interconnections with the speaker terminals
Connections to the HI LEVEL INPUT
5
plugs
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
HI LEVEL INPUT
5
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
4
plugs
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
LEVEL OUTPUT
4
terminals must be connected to the L (left)
and R (right) HI LEVEL INPUT
5
ones of the second subwoo-
fer. The input signal must then arrive into the first subwoofer by
its L (left) and R (right) HI LEVEL INPUT
5
terminals.
The signal from the L (left) and R (right) HI LEVEL OUTPUT
4
plugs, filtered at 200 Hz is the one being brought in by the
HI LEVEL INPUT
5
connectors.
These outputs can thus be used to bring the signal to the main
loudspeaker systems.
Power supply
The AC IN
3
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
2
. Switch POWER
1
,
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 auto-
matically when signal comes back.
Attention, before operating the unit, be sure that the operating
voltage of your unit is identical with that of your local power vol-
tage.
ADJUSTMENTS
LEVEL
0
For a first volume adjustment, position the CROSSOVER FRE-
QUENCY
9
at around 120 Hz, and turn slowly the volume
LEVEL
0
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
9
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
9
. Attention, if you use 2 sub-
woofers, both phase switches must be on the same position.
