The DX0.4 is the ideal processing tool to partner the ADORN, CDD and BlacklineX ranges or indeed any system where comprehensive system control and protection is required, perhaps where there may be budget constraints.

The DX0.4 offers a substantial array of processing options. Routing is freely assignable from the 2 inputs to the 4 outputs. Input and output equalisation is available with a choice of 16 filter options. An input noise gate will help deal with noisy signal sources. Input and output delay is available to time align components in a system. Crossover filters with slopes from -6dB/octave up to -48dB/octave are available in the three most popular filter types, and a twostage limiter; program and peak, will protect your speakers from damage due to excessive power.
