Automatically securing the most reliable signal in a matter of seconds and scalable to 90 channels thanks to 56MHz tuning bandwidth, it's easy to see why this wireless system is in a league of its own.

Equidistant Spacing - easier than it sounds

Evolution Wireless Digital features an equidistant tuning grid previously only found in our flagship Digital 6000 and Digital 9000 wireless systems. Quality components with exceptional linearity eliminate intermodulation between EW-D transmitters, allowing frequencies every 600 kHz to be evenly juxtaposed. This simplifies frequency coordination for wireless novices and seasoned professionals alike, while also contributing to the system's scalability and impressively high channel count.
