3.1 FULL-RANGE mode
In FULL-RANGE mode, the KARA system operates over the nominal bandwidth of the enclosure.
It corresponds to the use of the KARA line source in standalone configuration, i.e. without complementary subwoofers.
The KARA enclosure is driven by the LA8 amplified controller with a dedicated factory preset.

Frequency range (-10dB)

3.2 LOW-EXTENSION mode
In LOW-EXTENSION mode, the bandwidth of the KARA system is extended in the low end.
It corresponds to the use of a KARA line source in combination with the SB18 subwoofer, the SB28 subwoofer or both
the SB18 and the SB28.
Each enclosure type is driven by the LA8 amplified controller with a dedicated factory preset.
The KARA enclosure is driven by the same preset as in standalone configuration.
The upper frequency limit of the preset driving the SB subwoofer will depend on the coupling conditions.
COUPLED or SEPARATED in sub/main system combination
To achieve close coupling, respect the maximum distance between adjacent lines or the maximum mixed line
configuration. When exceeding these limits, refer to the presets and ratios corresponding to separated subs.
