The following settings are available for each loudspeaker:
• The type of high-pass or/and low-pass filters is chosen in the dropdown menu using
• The cut-off frequency of each filter is set by using the arrows or by manually enter the frequency
• Level and delay can be adjusted on each way (driver),
• Mute and Invert Polarity buttons are also available.
• Two additional IIR filters are available under the name of “Constant-directivity horn” EQ and Half “Con-
stant-directivity horn” EQ . The purpose of such filters is to boost the high frequencies for speakers that use con-
stant-directivity horns. These speakers tend to have too little energy at the highest frequencies in sweet spot. De-
pending on the horn you are using, you may want to boost the high frequencies by 3 or 6 dB/oct, from about 3kHz.

• The Apply button is highlighted as soon as a parameter is modified and is used to compute and load the new
settings into the processor. Once compute is finished the gears icon disappears from the notification bar, and
filters are applied to the outputs.
• If the changes are unwanted, press the Cancel Changes button to cancel your modifications.
• If change is accepted, press the Save button of the preset of your choice in the Presets page to save the changes,
otherwise changes will be lost.
The theoretical model of the specified filters is represented as follows:
• The green curve represents the theoretical low-pass filter response
• The red curve represents the theoretical high-pass filter response
• The blue curve represents the theoretical resulting response of the speakers
