Digital loudspeaker management – part 2

Lautsprecher Management

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!

Digital loudspeaker management

Lautsprecher Management

Digital loudspeaker controllers are the heart of every modern PA-system. Controllers assign the matching signal to every speaker, balance inconsistencies in the frequency range and protect the system from overload.

Loudspeaker controllers normally consist of these three important components:

– the hardware including the connectors and interfaces, the transducers, the operating elements and the housing.

– the firmware includes algorithms for signal processing, i.e. equalizers, crossovers, limiters and delays.

– the software providing a graphical surface on the user’s computer for adjusting all controller functions and settings and manage complete setups. Read more »
