50. Parametric EQ
This versatile parametric equalization program offers precise
sound-shaping control so you can create precisely a required
tonal effect
High-pass Filter (HPF): THRU, 32 Hz
—
1000 Hz
Permits rolling off the the low-frequencies below the set
frequency. The HPF is OFF when set to THRU.
Midrange EQ Frequency (MID FRQ): 315 — 4,000 Hz
Sets the mid-frequency range to be boosted or cut using
the next parameter: MID GAIN.
(dBI 20

IHz)
Midrange EQ Gain (MID GAIN): -15 — +15 dB
Boosts or cuts response in the frequency range set by the
MID FRQ parameter (above). A setting of 0 produces no
boost or cut. Minus settings (e.g: -6 dB) cut response in the
selected frequency range, while plus settings (e.g: +12 dB)
boost response.
Midrange Bandwidth (MID Q): 0.32 — 10
Sets the bandwidth of the range of frequencies to be
boosted or cut using the MID GAIN parameter. The higher
the value, the narrower the range of frequencies affected.
High EQ Frequency (HI FRQ): 800
—
8,000 Hz
Sets the high-frequency range to be boosted or cut using
the next parameter: HI GAIN.
High EQ Gain (HI GAIN): -15 — +15 dB
Boosts or cuts response in the frequency range set by the
HI FRQ parameter (above). A setting of 0 produces no
boost or cut. Minus settings (e.g: -6 dB) cut response in the
selected frequency range, while plus settings (e.g: +12 dB)
boost response.
High-frequency Bandwidth (HI Q): 0.32 — 10
Sets the bandwidth of the range of frequencies to be
boosted or cut using the HI GAIN parameter. The higher
the value, the narrower the range of frequencies affected.
Low-pass Filter (LPF): 1 kHz —11 kHz, THRU
Permits rolling off the high-frequencies above the set
frequency. The LPF is QFF when set to THRU.
EQ Delay Time (DELAY): 0.1
—
400 milliseconds
Determines the time it takes for the equalizer to actually
take effect after a note is played.
