Biamp A4 - Manual (Page 132)

Audia-Manual-A4
Feedback Suppressors behave like automatic cut-only parametric equalizers . They utilize
'floating' bands of equalization which detect and remove feedback frequencies.
Active Band selects the current band for which settings will be displayed. Center Freq.
displays the center frequency for the current band. Gain displays the amount of cut applied at
the center frequency for the current band. Bandwidth displays the range of frequencies, above
& below the center frequency, which are also affected by the current band. Float Limits restricts
all floating bands to a selected maximum depth (cut) and bandwidth (Narrow = 1/40-octave;
Wide = 1/10-octave). Reset All temporarily returns the gain of all floating bands to 0dB (flat).
Fix Band
& Fix All allow the band(s) to become manually adjustable (non-floating). Bypass
Band & Bypass All disable the band(s) without changing settings. Drag Points turns on/off the
band controls, revealing the resultant curve only. Band highlights the current band inside the
graph. Band Utilization Count indicates the quantity of floating bands currently being
employed.
NOTE: Feedback Suppressors are fairly intensive in their use of DSP resources. They are
limited to a maximum of sixteen bands, however, in most applications the number of actual
bands used should be significantly less. Fixed bands in a Feedback Suppressor may be copied
to a Parametric Equalizer. When applicable, this may be a more DSP efficient choice.
Right-clicking over certain settings will provide a menu of additional options.

These Component Objects provide High-Pass, Low-Pass, High-Shelf, Low-Shelf, & All-Pass
filters. Filters may be connected between any components within the Layout, for applications
which require 'roll-offs', simple tone controls, or even phase compensation.
Once a Component Object is placed into the Layout, all available settings can be accessed by
double-clicking over the object. This produces a Control Dialog Box, which displays the
component controls in a more conventional user interface.

Right-clicking over the object provides a pop-up menu of options.
