Shelv- filter
A shelv filter can be found in nearly every mixing desk, normally for low and high
frequency adjustment. They can boost or cut a wide frequency range above (high
shelv) or below (low shelf) the mid- frequency. Furthermore we added shelv filters
with adjustable bandwidth (
LSQ and HSQ ) which are, corresponding to the value of
the „Q“ facto (we recommend values between 0,4 and 4,0), either more “flat” than
“normal” shelvs (Q=0.7) or with a higher “Q” (1.0 to 4.0) they create an useful “peak”
around the mid frequency.
Setting the bandwidth outside of Q <0,4 und Q >4,0 is
not recommended.
LS 6dB
Lo- Shelv- Filter 6 dB
mid frequency 20 Hz - 44 kHz
Boost/cut + 12 dB - - 20 dB
LSQ 12dB
Lo- Shelv- Filter 12 dB with adjustable “Q” factor
mid frequency 20 Hz - 44 kHz
Boost/cut + 12 dB - - 20 dB
bandwidth „Q“ 0,1 - 20
At Q= 0,7 you have a „normal“12dB- Shelv- Filter.
Setting the bandwidth outside of Q <0,4 und Q >4,0 is
not recommended.
HS 6dB
Hi- Shelv- Filter 6 dB
mid frequency 20 Hz - 44 kHz
Boost/cut + 12 dB - - 20 dB
HSQ 12dB
Hi- Shelv- Filter 12 dB with adjustable “Q” factor
mid frequency 20 Hz - 44 kHz
Boost/cut + 12 dB - - 20 dB
bandwidth „Q“ 0,1 - 20
At Q= 0,7 you have a „normal“12dB- Shelv- Filter.
Setting the bandwidth outside of Q <0,4 und Q >4,0 is
not recommended.
