PANEL CONTROLS (see figure 7)
The S220 subwoofer has a wide variety of features, including:
-
Variable volume (level) control (Min-Max)
- Phase Switch (0-180)
- Variable phase control (Min-Max)
- Variable low pass crossover (40 Hz to 200 Hz)
- Variable Bass Equalizer (Min-Max)
- Switch able high pass filter
- Switch able mid bass EQ
- Auto turn-on
- High and low level inputs
- Low level outputs
- Switch able power supply (110/220V user selectable)
The cabinet of the S220 uses 19mm thick high-density composite walls. The cabinet is
finished in a beautiful black satin finish.
The amplifier is a 220W RMS class D design. It features large storage, oversized power
supply capacitors, and a large external aluminum heat sink to ensure long-term cool
operation.
The driver is a long throw 12 inch driver, heavy gauge cast aluminum basket, epoxy-
reinforced paper pulp cone. The linear motor strength curve from this motor ensures
extremely low distortion and compression over the full operating bandwidth, as well as a very
high transient response.
EXPLANATION OF PANEL CONTROLS
The Final Sound S220 subwoofer has some additional features, to make the most optimal
match with the Final electrostatic loudspeakers. The chapter ‘ Connecting the S220 to your
system’, will explain which equipment you need to use these special subwoofer features. The
connection between a regular subwoofer and an electrostatic driver, brings some additional
interface considerations. The Final sub’s build in high pass filtering and other features,
guarantees the best possible integration between a subwoofer and an electrostatic panel.
Connecting and setting up the system using the additional features is a little bit more
demanding. In order to make life easy, we provide you with a quick set up procedure.
Standard Controls
The level control allows setting the gain of the built-in amplifier to match your main
loudspeakers. A total range of 60 dB is provided, allowing integration with nearly any audio
system.
Phase can be switched to 0 or 180, depending on the sub’s position relative to the base line
between the loudspeakers.
The Variable Phase control compensates for the time-delay between the panels and the
subwoofer. The right position depends on the distance from the sub to the base line. If the
subwoofer is located elsewhere in the room, this control compensates for the time delay
