What does a Loudspeaker Management System actually do?
The concept of an Loudspeaker Management System is to provide all the electronics you might need in front of an amplifier in one box. In an active system the crossover comes before the amplifier. This means you need more amplifier channels to deal with the split up frequency bands but gives massive advantages. In low voltage electronics it is much easier (and more efficient) to manipulate audio than in passive crossover networks. For example a single power amplifier powering a passive crossover which splits the frequency range into two drivers has lots of problems: 1. You lose a lot of energy (amplifier watts) as heat in the components of the crossover. 2. It is not possible to design steep roll-offs so a broad band of frequencies are covered by both components, which causes smearing between the drivers and potentially raises the distortion from the individual components. An obvious example is an HF compression driver run at low frequencies, being forced to produce bigger mechanical ex
