The Electro-Voice Dx34A is a multifunctional digital sound system processor. Its high degree of flexibility enables the set up and optimization of active multiway loudspeaker systems with variables previously unavailable in a single-rack-space device. The unit can be configured in two-way mono with a separate full-range direct out, and four-way mono. In the three-way configuration, the low and direct outputs can be individually set to be a sum of two input channels, useful in some applications, e.g., mono subwoofers with stereo main speakers.
