Low pass
This rotary potentiometer is used to adjust the subwoofer's low-pass cut-off frequency in order to determine the highest
frequency that the Sub12 will have to re-transcribe. The aim of this setting is to optimise the Sub12's cut-off frequency. The aim
is of course to obtain the most linear frequency response curve possible from the whole system (subwoofer + loudspeakers).
The low-pass crossover is no longer active as an LFE channel.
Polarity
This polarity switch inverts the Sub12 phase by 180°.
Phase
This "fine tuning" phase-adjustment potentiometer, combined with the polarity switch (seen above), will allow you to
compensate for the positioning of the Sub12 in relation to that of the other loudspeakers. Depending on the distance of
the subwoofer, on whether it is in a central position or not, this setting will allow you to simultaneously receive the sound
information coming from the Sub12 and its linked loudspeakers.
2.1 Bypass/Mute
This input allows you to connect a 2-position control pedal (not supplied), using a 1/4" (6.35mm) jack.
Enabling the BYPASS will:
- activate the subwoofer's "Mute" function
- deactivate the high-pass crossover for the linked satellite loudspeakers. The loudspeakers will then operate at their full
bandwidth.
This action will authorise the instant comparison through rapid switchover, between a "2.1" system (Sub12, linked to 2
loudspeakers) and a traditional stereo system. This option will be particularly useful when optimising the crossover settings
(phase, cut-off frequency, volume) between the Sub12 and its linked loudspeakers.
Power light
POWER LED: on (continuous green), stand-by (continuous red), protection (flashing red)
2.1 BYPASS/Mute LED: on (continuous green)
Focus
The Sub12 can be linked to the Focus mode of satellites using the dedicated Focus input and output.
