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 maxi-
mize flexibility
. Two configuration modes allow clearer han-
dling 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 cur
rent EV speaker and amp data.
