Parametric EQ
Parametric equalizers allow precise control of the amplitude, center
frequency and bandwidth of these bell response filters.
Each channel of the amplifier has four bands of parametric EQ. These
EQs can be used to compensate for peaks and dips in the frequency
response of certain speakers, eliminate feedback, and reduce or
enhance any area of the frequency spectrum. The attached frequency
diagram will help identify the frequencies that may need to be adjusted.
Each parametric EQ has three adjustable parameters:
Amplitude: the level of increase or decrease in decibels (cut or boost up
to 15 dB)
Frequency: the center frequency of the bandwidth being adjusted.
Bandwidth: the width of the frequency band being adjusted. The
bandwidth control is adjustable from a narrow 3/10 of an octave for
precise filtering to a wide 2 octaves for broad control.
To adjust each EQ simply scroll to the desired EQ and press the
navigation encoder to adjust each parameter (Fig. 24). Repeat for each
of the four EQs on channel A and B.
HORN EQ
The horn equalization in the IPR
™
DSP provides a gentle, rising
high-frequency boost to compensate for the roll-off inherent to most
high frequency horns. Adjust the frequency and level to achieve the
desired response. (Fig. 25)
