PARAMETRIC EQ
Parametric EQ offers a minimum phase four band parametric EQ.
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section. For
this algorithm, we recommend a setting of 99.
03 — Bass Fc Range: 0 to 1000 Hz
Sets the center of the low frequency EQ.
04 — Bass Gain (loShv) Range: -48 to +24 dB
Sets the amount of boost or cut applied to this low frequency parametric.
05 — Mid1 Fc Range: 100 to 9999 Hz
Sets the center of the mid frequency parametric.
06 — Mid1 Gain Range: -48 to +24 dB
Sets the amount of boost or cut applied to this mid frequency parametric.
07 — Mid1 Q Range: 01 to 18
This parameter is a bandwidth control that determines the width of the resonant peak at the
center frequency band. This parameter is equal to the cutoff frequency divided by the
bandwidth. By raising the value, you can produce a narrower bandwidth.
08 — Mid2 Fc
09 — Mid2 Gain
10 — Mid2 Q
These three parameters are identical to the previous three parameters, and are used to control
different bandwidths within the mid range.
11 — Treble Fc Range: 01 to 16 KHz
Sets the center frequency of the high frequency parametric.
12 — Treble Gain (HiShv) Range: -48 to +24 dB
Sets the amount of boost or cut applied to this high frequency parametric.
13 — EQ Input Level Attenuation Range: -24 to +00 dB
Adjusts the input level trim to the EQs to eliminate the possibility of clipping boosted signals.
