Electronic Diplexers

The uprise of processing systems has slowed down the run on the market for electronic diplexers. The combination of high-quality DSP´s and the neccessity of an active diplexer created the speaker-management-system descibed in the earlier chapters which you can find in every semi-professional sound system today.

Inspite of these complex profis most manufacturers still offer a "conventional" electronic diplexer which differs from a standard diplexer (e.g. a fullrange-box) because it works on an electronic basis. The active diplexers are applied between the mixer and the amplifier. Their job is to seperate each audio-signal that comes from the mixer into individual frequence-areas. Settings in two, three or four areas are normal. These seperate areas arrive at different amplifiers, so that every portion can be supported individually. The seperation of speakers with active diplexers has the following advatages: The seperate speaker-systems gain an adequate power supply so that the speakers are protected and the speaker balancing in the different frequencies enable a rough sound adjustment.


Speaker Management Systems

Today the modern semi-conductor-technology offers very strong DSP´s and high-quality AD/DA-converters at conciderable prices which generated complex mix-/matrix-units with in- and outputs. At the same time speaker manufacturers have developed professional active diplexers for their own active single speaker systems. The combination of the high-quality DSP and the neccessity for an active diplexer generated so called speaker-management-systems on a DSP-basis which can be found in nearly every semi-professional sound system today. They are no longer tied to a specific speaker manufacturer, but can be used seperately for every active speaker-set. Voluminous adjustment possibilities and partially retrievable settings for the corresponding speakers make the usage for non-experienced musicians sweat and simple.
