.
• Note that you may need to try more than one location for the subwoofer to reach
optimum results.
TABLE 1 Recommended Crossover Settings
* when using the LFE-output for driving the subwoofer, the panel’s ‘size’ parameter should be set to ‘small’. Otherwise, most
theatre processors won’t activate the LFE-output
The S220 is also usable in combination with the Final 90i, 150i and 300i panels. Mainly for home theatre applications.
PROCEDURE B
– QUICK INSTALLATION-
Using the Final Sound S220 special high pass filter facilities.
In this position, the sub’s special high pass filter facilities are active. Basically, the incoming
full range signal is split into a low pass filtered signal driving the subwoofer, and a high pass
filtered signal driving the left and right front panels. The high pass filter’s crossover frequency
is not endlessly variable. It has three pre chosen fixed frequencies, which fall into the usable
range for the panels. The ‘Mid Bass Equalizer’ switch on the sub’s back panel, will also give
you three positions.
• Position the S220 in the desired location.
• Connect the S220 according to this manual’s instructions.
• Set the sub’s Level control to a minimum and the Phase Switch to 0 degrees (as a
starting point).
• Adjust the sub’s Low Pass control (crossover frequency) to the panel’s lowest
frequency (see Table 1 or 2).
• Now play some music and gradually turn up the sub’s Level control to a value that
matches the main loudspeaker’s level.
• Adjust the Variable Phase control now. This is ONLY necessary if the subwoofer’s
position is NOT on the baseline between the loudspeakers or left to the left
loudspeaker and right to the right loudspeaker. If the subwoofer is before or behind
the baseline, or somewhere else in the room, adjustment of the phase might be
necessary. Play some modern music with a strong bass-rhythm to adjust the phase.
The Phase control is in the right position, if you’re not aware of a time difference
between the mid/high frequencies and the lower frequencies on the listening position.
The system is definitely out of phase when the bass frequencies lag behind the rest of
the spectrum or there’s a time difference anyway. If it’s not possible to get the right
timing, reverse the Phase Switch from ‘0’ to ‘180’ and try again. If this is not helpful,
diminish the distance between the subwoofer and the electrostatic panels.
