Electro-Voice DX38 Controller

Digital Sound System Controller

Dx38 sets standards for digital loudspeaker controllers and processors, providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115 dB. Dx38 can be used in networks of up to 31 controllers with a maximum networking distance of 1.000 meters. Real-time controlling and configuration is either via the front panel or PC via RS-232, MIDI or RS-485 bus for networking.

Dx38 is a 2-in/4-out controller with a "virtual" third input source. It has a mono sum of both input channels to maximize flexibility. Two configuration modes allow clearer handling for different qualified users. 30 user memories and 50 factory presets can be managed. The Dx38 comes with a detailed manual plus RACE software which includes current EV speaker and amp data.

Software for Dx38

RACE is a professional audio tool to generate presets for speaker systems. In addition to the clear display of all used filters, delay and level settings, each output can be assigned with the acoustic data (phase and frequency response) of the individual speaker component. This pure speaker data has been measured in free space. RACE then calculates the complex summation of all used filters, level and delay settings applied to these components. Thus the display on the screen is not only the electrical filter response but, for the first time, the actual true acoustic response of the component! Any change of parameter values is visible and audible in real time. An additional tool is the SPL dispersion window for lower frequencies. Presets can even be prepared off-line in advance and need only a little tweaking once speakers are in place. RACE enables engineers to seamlessly integrate room influence, speaker positioning and parameter settings and a RACE Processed Preset is a guarantee for a solid, accurate basis from which to begin system tuning. EV is supplying
these presets for all current EV speaker systems, even if the needed combination is not part of the 50-factory preset of the Dx38.
