Bosch Security Systems B.V.
Range Description
Switch for displaying amplitude frequency response (magnitude) or
phase response (phase)
Switch for scaling the amplitude axis to 25 dB (± 12.5 dB) or 50 dB (±
25 dB)
Switch for changing between bandwidth BW and Quality Q when
setting employed filters.
Pressing BYPASS ALL switches of all filters.
Name of the corresponding filter band. Clicking with the right mouse
button onto this field opens Copy & Paste menu, which allows
comfortably copying all EQ parameters of the selected filter to any
other EQ within the same project.
PEQ. TYPE defines the filter type.
Loshelv. – PEQ is a parametric Peak Dip Filter with its frequency, quality (Q)
His- helv, and gain being programmable.
Hipass, – Loshelv / Hishelv create a Low-Shelving or High-Shelving filter
Lopass, with the parameters being: frequency, slope and gain.
Allpass – Lopass / Hipass creates a Low Pass or High Pass filter with
adjustable frequency and slope.
– Allpass is a filter that has no influence on the frequency response
but on the phase response in the transmission function.
-18...+18 GAIN defines the amplification (increase) or attenuation (reduction) of
dB parametric EQs or low shelving and high shelving equalizers.
20 Hz...20 FREQ (frequency) sets the center frequency of a parametric EQ or the
kHz cut-off frequency of shelving and Hi / Lo pass filters.
