Digital loudspeaker management – part 2
We want to complete the list of tools described in the first part. We start with equalizers – also a vital part of oudspeaker controllers. The frequency range of a PA-system can easily be corrected with fully parametric equalizers. While mixer equalizers are mostly semi-parametric, i. e. only amplitude and frequency can be changed, a fully parametric equalizer can also change the filter bandwidth or shape of the bell. Consider that a high filter bandwidth (Q-factor) equals a small bandwidth and vice versa. As already mentioned, too harsh adjustements of the frequency response have to be avoided because the phase problems make the positive effects of the correction void. Here, less is often more!
