Infrasonic Filter - DSPeaker Anti-Mode 2.0 Owner's Manual

EXAMPLE: Adding a -3dB treble tilt-down above 5 kHz
Background: Some recordings seem too bright or 'toppy' in their
tonal balance. To compensate this the high frequencies can be
toned down using a subtle high frequency attenuation filter.
How to do it step-by-step:
➢Open main menu by pressing the MENU button.
➢Navigate to the Settings menu using the arrow buttons and press OK to
select it.
➢Select the Tilt Curve using the arrow buttons again (the first element
on the lower row.) Press OK to open the Tilt Curve tool.
➢Now you can adjust the pivot frequency using LEFT/RIGHT arrow
buttons, until the value is 5000Hz.
➢Use the UP/DOWN buttons to set attenuation to -3dB. You can see the
approximated frequency response of the filter on the screen.
➢To save the filter, press OK.
At any time, you can disable the tilt curve by opening the Tilt Curve tool
again and pressing the green-coded button to disable the effect,
followed by OK to apply the changes.

Infrasonic Filter

The Infrasonic filter tool is a quick way to apply a subsonic highpass filter that filters
out the signals below the audible band. The motivation behind an Infrasonic filter is to
protect the woofer cones and to eliminate the effect of infrasonic harmonics and/or
inter-modulation distortion. It is recommended to use an infrasonic filter whenever
excessive house curve or low frequency boosting parametric equalizers are applied.
The controls of the infrasonic filter are:
✔Frequency: The frequencies below this threshold are attenuated.
✔Enabled: Enables or disables the infrasonic filter.
Use the directional buttons on the remote controller to change the parameters. Press
the OK button to store settings or the BACK button to cancel.
Note: You can also design a custom infrasonic filter with the Lowpass/Highpass tool,
which gives more control over the parameters (see High/Lowpass filters section
below.)
