The FIR EQ are available in the menu Processor/Outputs.
You can link several speakers. Every FIR EQ set to one speaker will automatically be applied to the other speaker
linked.
For every speaker in the room, a FIR EQ can be defined in terms of:
• Amplitude only (dB)
• Amplitude and Group Delay (ms)
• Amplitude and Phase (°)
One or more channels can be linked in order to apply the same FIR EQ to several speakers.

The required curve can easily be edited via the touch screen or with the arrows of the keyboard:
• The green dots correspond to the required values for each frequency,
• The yellow line displays the expected result, taking into account the behavior of the filter.
The FIR EQ will be saved and reloaded with the whole Preset, through the usual Presets page. Press the Close but-
ton to apply the changes and get back to the Processor/Outputs tab.
!
NOTE: by default, since the length of the FIR filter is 100ms (as defined in the Advanced Settings), the FIR Equalizer has a
constant resolution of 50Hz. This implies that it has very low resolution at low frequencies; it should therefore not be used
to work on specific frequencies in the low range. Instead, it should be used to change the tonal balance as a whole.

IMPORTANT NOTE: Please keep in mind that the changes will not be applied until you press the OK button.
7.1.5.2 _ 31 BAND GRAPHIC EQS
In addition to manually setting levels, the Processor/Inputs and the Processor/Outputs pages include 31-
band, 1/3 octave Graphic Equalizers that allow for manual equalization of each input or output channel:
• Input EQ is available on the input channels,
• Preset EQ and User EQ are available on the output channels
The Input EQ behaves exactly in the same way as the Preset EQ described below. The only difference is that it is
applied to the inputs instead of the outputs.
The “Preset EQ” and “User EQ” buttons in the Processor/Output page give access to two independent Graphic EQs.
Both EQs have the same interface (only the current EQ name at the bottom left of the window is added for the User
