To the left of the window is the selection list for one of the two banks (FBKILLER 1 and FBKILLER 2).
Clicking on one of them allows you to adjust their settings:

 OUTPUT: the system output the filter bank is applied

to in order to cancel or minimize its potential
feedbacks (outputs 1 to 4 and also 9 to 12 in the
case of a MASTER-SLAVE MIMO88CONF)




 TARGET: allows you to select among 4 preset application

profiles, each one of them with the algorithm optimized for the
application. Each of these profiles adjusts algorithm internal
parameters such as the feedback detection sensitivity and the
maximum attenuation applied by the filters. It is important to
correctly set this parameter taking into account the application
characteristics (music or speech) and the room type where to
work (large or small), given that its own reflections and modes differently affect the risk of
feedback in all the cases considered as profiles for the TARGET parameter. A conference
application using a MUSIC profile will surely give worst results than if you employ a SPEECH
profile, and vice versa.

 FIXED FILTERS (from 0 to 8, per bank):

determines the number of filters that, once
set, remain fixed over time (static) until you
change the MIMO88CONF setting that
affects them (recalling a preset with other
settings, loading a new project, rebooting
the computer, etc.). A horizontal line visually
separates fixed filters (the first three in this
picture) from dynamic filters (the following
five in this picture). Dynamic filters can be
reset over time if the algorithm detects that it
is necessary (microphones moved in the room, changes in the acoustic conditions, etc. ).

 FILTER WIDTH (1/5 or 1/10 Octave): determines the bandwidth of each one of the notch filters of

the bank, or the frequency range that will be affected (attenuated) by each filter, using its centre
frequency, automatically detected, as the centre of this range

 RECYCLE TIMER: determines the

minimum necessary time between the
setting of each dynamic filter and its
releasing for a new setting on another
frequency of potential feedback, when the
algorithm detected this need

 LOCK: locks the status of already set filters, not allowing more static filters setting (if any) nor

dynamic filters setting or resetting

 BYPASS: when activated, temporarily disables the FEEDBACK KILLER function, while keeping

the adjustments and filters set in memory. When deactivated, re-enables the function, recovering
the previous settings

 RESET: totally resets the 2 banks of filters, now available again for setting
