INSTALLATION
With a crossover point below or around 150 Hz, the installation position of
subwoofers is not limited as human ears and brains are not able to identify the
emitting point of such low frequencies.
To get the best result, it is recommended to try different positions and choose
the one giving the best response in the low frequencies, taking into account the
room acoustics.
HOOKING UP THE SYSTEM
2 possibilities are offered to connect the subwoofer with your system:
- the low level one requiring the use of the CINCH RCA LINE IN (7) and LINE
OUT (6) terminals and shielded coaxial connectors,
- the high level one requiring the use of the speaker HI LEVEL INPUT (5) and HI
LEVEL OUTPUT (4) terminals, and standard loudspeaker cables.
The inputs are stereo ones, the mix of the L (left) and R (right) low frequencies
being done by the amplifier of the subwoofer. If the input signal is already mono,
only one input L (left) or R (right) should be used.
2.1 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) outputs to the L (left) and R (right)
LINE IN (7) inputs of the subwoofer.
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 amplifier powering the
main loudspeaker.
2.2 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 low-
level output, you should then connect the subwoofer 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 loudspeaker 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 subwoofer. 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.
2.3 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 automatically 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 voltage.
2.4 Adjustments
- LEVEL (10)
For a first volume adjustment, position the CROSSOVER FREQUENCY (9) at
around 120 Hz, and turn slowly the volume LEVEL (10) clockwise from minimum
level up to a position where 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 listening tests.
- PHASE (11)
For a better sound integration of the subwoofer in the main system, the
PHASE (11) of the subwoofer might have to be inverted (180° position),
depending on the distance between the subwoofer and the main speakers.
You have to check the PHASE (11) each time you move your speakers and
each time you adjust the CROSSOVER FREQUENCY (9).
Attention, if you use 2 subwoofers, both phase switches must be on
the same position.
