The Phase Inversion submenu switches the phase of the signal. In other words, it allows to invert or
„reverse“ its polarity. Two settings are available:
-
Normal: In phase setting.
-
Inverted: The phase/polarity is inverted by introducing a 180°phase shift to all frequencies.
Only for Parametric filters.
DSP SETTINGS > EQUALIZERS (EQ1 TO EQ5)
For system tuning purposes, 5 user-adjustable equalizers are available offering the following parameters:
-
Bypass: On (the EQ is bypassed) or Off (the EQ is active).
-
Type: Low Shelf, Parametric or High Shelf.
-
Gain: -12 to 12 dB, with 0.1 dB steps.
-
Freq: 20 Hz to 1kHz, 1 Hz steps. Sets the center frequency for Parametric filters, or the edge frequency
for Shelf filters.
-
Slope: 0.5 to 2, with steps of 0.1. Only for Shelf filters.
-
Quality: 0.01 to 16 with steps of 0.01, where higher Quality Factor values mean narrower bandwidth.
Only for Parametric filters.
An example of a parametric equalizer with EQ1 in parametric mode is shown below.

To modify equalizer parameters, follow the same steps detailed in the Highpass Filter section.
Notice that the equalizers can be individually bypassed, their default setting.
DSP SETTINGS > BYPASS USER EQ
In order to compare the response of the subwoofer with and without the applied EQ, this section allows to
bypass all user EQs with a single click.

Remember that user EQs are bypassed by default and can be activated individually.
DSP SETTINGS > DELAY
The Delay section allows the user to apply a delay to the signal, visualize it in different units and determine
the total delay. This screen has the following three sections:
-
User added delay: This is the delay defined or added by the user depending on the specific needs of
his application.
-
Preset delay: Depending on the preset enabled or selected, the system may include an additional
delay. This delay is added by the current preset and for some factory presets, it can be also edited.
-
Total DSP delay: Total sum of "User", "Preset" and internal DSP latency. It is not an editable parameter
and is only shown for information and reference.
The "User" and "Preset" delays can be defined in three different units, corresponding to the editable
parameters in the first two delay sections:
-
Samples: for 48 kHz sampling rate.
-
Time: Delay in milliseconds (ms), referred to the 48 kHz sampling rate.
-
Distance: Delay in meters (m), referred to c = 343 m/s.
When changing a parameter in any section, all the other parameters are updated with the corresponding
value in their units.
