Powering ON
Powering ON should be carried out as follows :
- Check once again that all connections are correct and that the volume button of your amplifier is
at minimum.
- Connect the power plug ( after checking that your power supply voltage corresponds to the
one on the equipment 230V or 120V ).
- Place the Auto selector switch to ON to activate the automatic powering ON, or OFF to desactivate
the automatic powering and use the remote control to switch the subwoofer ON. When using this
function, the subwoofer will automatically go into standby mode if it does not receives any signal.
- Switch the ON /OFF switch to ON.
- Adjust the volume, frequency and phase buttons (see Settings).
Note : Cut off the power supply of the subwoofer by using the power switch when it is not in use
for several days.
Positionning and settings
Position your subwoofer in the forward listening zone (if possible between the two main speakers)
for a better sound resolution.
This subwoofer can be used with any type of loudspeakers.
The ideal setting should correspond to a realistic reproduction of the bass and be adjusted the best
possible with your main loudspeakers. You should not «feel» the subwoofer, the bass should seem
to come from the main speakers.
The phase inversion switch can be used to to reach the best result possible. This switch is used to
inverse the phase of the sound signals coming from the subwoofer. Depending on the placement
of the subwoofer in the room in relation to the main speakers, inverting the subwoofer phase can
lead to a better coherence of the system’s global response in the bass frequencies.
We recommend you to carry out various tests until finding the setting which suits you the best. Use
a recording you know well and study the result according to your taste and expectations.
Using the subwoofer’s internal filtering
The frequency is tuned to the main speakers by using the «CROSSOVER» potentiometer. The
adjustment is made in the frequency range between 30Hz and 120Hz.
Carry out tests by first positioning the setting switch between 30Hz and 80Hz with large delete size
main speakers and between 80 and 120Hz for small delete size speakers.
