Martin Audio DX0.4

DSP-Based System Controller

2-in-6-out

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 14 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 two-stage limiter; program and peak, will protect your speakers from damage due to excessive power.

The processor feature 32 User Memory locations to store popular configurations and settings can be exported to a file via the dedicated PC application. PC connectivity is available via a front panel USB port for quick and easy connection of a single processor, but larger systems with several processors can use Ethernet or RS485 network connections.

A very useful function is the ability to recall entire output channel configurations and a comprehensive library of output files for Martin Audio products is available making it very quick and easy to create exactly the configuration you need even where the system utilises products from several different Martin Audio ranges.

The DX0.4 features professional grade specifications to ensure the best possible sonic performance from your Martin Audio system, ideal for a wide range of portable and installed applications.
