Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. Automatically securing the most reliable signal in a matter of seconds and scalable up 90 channels thanks to 56 MHz of tuning bandwidth, it’s easy to see why this wireless system is in a class of its own.

Equidistant Spacing – simpler than it sounds

Equidistant Spacing – simpler 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 to be equally spaced every 600 kHz alongside each other. This simplifies frequency coordination for wireless beginners and seasoned professionals alike, and also contributes to the system’s scalability and impressively high channel count.
