NORMALLY THE SIGNAL PHASE DOES NOT NEED TO BE INVERTED.
THE PHASE INVERSION MAY BE USEFUL TO COMPENSATE OR
MINIMISE POSSIBLE UNDESIRED ACOUSTICAL DESTRUCTIVE
INTERFERENCES, DUE TO PARTICULAR LOUDSPEAKER
POSITIONS.
SAVE: it sends and stores the equalization to the selected device.
SEND: it sends (without storing)
the equalization to the selected device.
It is possible to set up
to 8 selectable filters:
DISABLED: the filter is disabled.
SHELVING_HIGH: increase or decrease the level of all frequencies
above the selected frequency by the specified amount.
SHELVING_LOW: increase or decrease the level of all frequencies
below the selected frequency by the specified amount.
PEQ: Parametric equalizer that allows to adjust the level L at the
settable centre frequency Fe and specify the bandwidth BW (the
adjusted level can be widened or narrowed).
LOW_PASS (available as first filter only): Butterworth 24 dBI
octavelow-pass filter (note:filter GAIN controlis disabled).
HIGH_PASS (available as second filter only): Butterworth 24
dBI octave hi-pass filter (Note: filter GAIN controlis disabled).
Frequency and gain can be adjusted either graphically (through
the mouse), by enabling the 'Visible' option (to visualize the filter
intervention) and moving the little coloured square or in an analytical
way, by inserting the values in the cells and then activating the 'Visible'
option. The overall equalization is shown as a red line, the intervention of
a single filter as a line of its respective colour and lower thickness.
