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:

Fig. 24

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)
