The Next Evolution... of Evolution Wireless

Sennheiser has a long and storied history in the world of professional audio, creating microphones used in all applications from world famous studios to Superbowl halftime shows. Part of that history is their Evolution Wireless product, first introduced in the year 2000. Our company’s first purchase order for the first generation of Evolution Wireless was dated January 7th of the year 2000 in fact, so apparently our computer system survived any potential Y2K bugs if you recall that fiasco.

Since the release of the first generation of EW series products, Sennheiser has continued to innovate and improve their lineup and has created one of the longest running wireless product series our industry has seen. Traditionally the Evolution Wireless brand has been a staple for mainstream venues such has churches, schools, and small to mid-size performance venues with Sennheiser having maintained a series or two above the EW series for major performance and broadcast applications.

This brings us to why we are so excited about the EW-DX product lineup. In recent years as live streaming and social media has changed the way we consume content, a place in the market for higher end features at a more traditional venue price-point has become very apparent. Sennheiser’s EW-DX lineup will fit at a place that we see an increasing need, for a variety of reasons:

  • Equidistant Channel Spacing. Increases the number of channels within 1 TV channel space with NO Intermodulation. Some serious science behind this.
  • 1.9ms latency. No Kung Fu movie artifacts here.
  • 2 channel operation in a half rack space receiver. More space in your case.
  • AF AND RF channel mute. Keeps the noise out of your PA when you thought you turned off the mic!
  • Transmitter Dynamic range over 14dB better than many others. Go ahead cup that mic.
  • Up to 12 Hrs. of battery life on the Lithium Ion rechargeables. Can you believe this guy is still talking?
  • OLED Display on the receiver, E-Ink Display on transmitter. No more scrounging for my mag-lite.
  • There are many other feature in the new EW DX that are notable, but these are the only ones that I could make a Smart Alec remark to describe.
