Signal optimisers: Crossover networks

DSM-48LAN and DSM-26LAN are professional digital speaker management systems of high power capability with state-of-the-art DSP processors and digital converters. These systems combine active crossover network, parametric equalizer, delay, RMS compressor and peak limiter in one unit. Thus, they are powerful tools in order to control every important feature necessary for a perfect speaker management in PA applications or for developing active speaker systems. Features and settings can be adjusted individually for each input and output channel. This is easily done directly at the unit or via the intuitive graphical user interface which can be accessed via PC, MAC or iPad. The connection is established via USB, LAN or WLAN (connection to a router is required). The DSP software is compatible with the MEGA-DSP, DSM-26LAN, DSM-48LAN and STA-1000DSP.

The DSP-26 is a speaker management system with state-of-the-art DSP processors and digital converters. This system combines active crossover network, parametric equalizer, delay, RMS compressor and peak limiter in one unit. Every feature and adjustment can be edited individually for the six output channels. It is operated directly at the unit or via the USB interface on the PC (or MAC) by means of an intuitively operated graphical user interface.
