The Band Pass filter sharply attenuates all frequencies except for a band
centered around frequency “f.” The setting of the “Q” control determines
the width of the pass band (higher Q = narrower pass band).
Low Pass Filters
EQ1 Low Pass 6dB
f: 6087
EQ1 Low Pass 12dB
f: 6087 Q:2.8
These filters pass signal below the cutoff frequency “f” and roll off signal
above “f” at either 6dB or 12dB per octave. The 12dB filter’s “Q” control
allows you to add a variable height peak at the filter’s cut-off frequency.
As you would expect, the 12dB/octave filter provides greater attenuation
of signals above “f” and is useful for reducing hiss or other high frequency
environmental noise encountered in the recording process.
High Pass Filters
EQ1 High Pass 6dB
f: 3775
EQ1 High Pass 12dB
f: 3775 Q:2.8
These filters pass signal above the cutoff frequency “f” and roll off signal
below “f” at either 6dB or 12dB per octave. The 12dB filter’s “Q” control
allows you to add a variable height peak at the filter’s cut-off frequency.
As you would expect, the 12dB/octave filter provides greater attenuation
of signals below “f” and is useful for reducing sub-sonic noise, rumble, mic
stand noise or other low frequency environmental noise encountered in
the recording process.
