HPF 100Hz
Activate the High Pass Filter
The High Pass Filter (HPF) is an 18dB/Octave lter that attenuates frequencies below 100Hz. This can be useful for
ltering out low ‘rumble’ from microphones aected by very low frequencies originating from for example, trac
noise, air ow and so on.
HF Level
Adjust the boost/attenuation of the high frequency shelving lter
The HF shelving lter has a xed frequency of 12kHz. Frequencies above this will be boosted or attenuated depend-
ing on the control setting. See section 1.02 for more detail.
MF Level
Adjust the boost/attenuation of the mid-frequency bell lter
This will adjust the gain or attenuation of the audio band centred according to the MF Frequency. This is an asym-
metric EQ, so boost has a wide bandwidth (low Q), and cut has a narrow bandwidth (High Q). See section 1.0.2 for
more detail.
LF Level
Adjust the boost/attenuation of the low frequency shelving lter
The LF shelving lter has a xed frequency of 80Hz. Frequencies below this will be boosted or attenuated depend-
ing on the control setting. See section 1.02 for more detail.
