Parametric Equaliser Screen
All modes feature a total of 30 bands of fully flexible parametric equalisation (5 per output), with
all sections selectable to Low or High frequency shelving response.
Each parametric section can be positioned at a frequency from 20Hz to 20kHz and features a wide
range of 'Qs’ to produce response curves ranging from broad to notch. The gain control ranges
from +15dB to -30dB in 0.1dB steps. Frequency steps are 1/36 octave resolution for precise control.
Since all filtering is achieved in DSP all settings are re-settable with absolute accuracy and in
ganged mode parameters track identically. Very narrow band notch filters (maximum Q of 128)
can be achieved and unlike analogue filters these 'tight' Q filters are entirely stable. The maximum
notch depth is -30dB.
Parametric filters are carefully implemented using Double Precision processing. This method is
costly in terms of processing power but yields substantial benefits in terms of the LMS-D6's
exceptional noise performance and greatly improved low frequency stability.
