<h2>High-headroom Digital Wireless Made Easy</h2>
<div class="webtext-copywriters">
Sennheiser Evolution Wireless Digital audio systems come trusted, tested, and recommended by pro audio experts — not only for their quiet operation, but also for their ease of use. These digital wireless audio systems sidestep the noise and interference common to traditional analog wireless setups, pushing the limits of dynamic range to an impressive 134dB. UHF transmission dramatically increases range and reliability across all Evolution Wireless Digital devices. Not only that, but 2,240 selectable frequencies on the 56MHz bandwidth make these systems highly scalable, allowing for up to 90 channels of audio per wireless network. Now your whole band can perform wirelessly on the same network without having to worry about stepping on one another’s RF real estate. Plus, the Evolution Wireless Digital series’ automated setup creates reliable connections without complicated menu diving; for advanced users, more granular configuration and setup options are available via the free Sennheiser Smart Assist mobile app for Android and iOS.

<h2>What’s Included:</h2>
<h3>EW-D EM receiver and rack kit</h3>
Sennheiser wireless receivers are longstanding favorites of audio professionals. As with past systems, the Evolution Wireless Digital receiver is deceptively simple to set up yet it packs plenty of control under the hood. Sync and Auto Scan options make it straightforward to connect and manage devices. Meanwhile, the crisp LED display shows signal strength and battery life of your connected device at a glance. And if you need more control, advanced features are just a few button presses away. Got a mobile device? Connect to the Evolution Digital Wireless receiver via Bluetooth using the free Sennheiser Smart Assist app for Android and iOS, and you’ve got a wealth of configuration and monitoring tools right at your fingertips. The EW-D receiver also includes a rack kit for seamless integration into your stage and studio pro audio setups.
<h3>EW-D SK body pack transmitter</h3>
The Sennheiser SK wireless body pack transmitter gives you full freedom of motion onstage, in the round, and on the platform. Connect your own lavalier mic, headset mic, or CI 1 instrument cable (each sold separately), and you’re locked and loaded for rock-solid wireless performance. The compact SK body pack clips discretely onto a belt or slips into a back pocket. A pair of AA batteries nets you up to eight hours of wireless operation. Want to go green and save some green in the process? Connect the optional Sennheiser BA-70 rechargeable lithium-ion battery pack (not included) and get up to 12 hours of performance on a single charge.
<h3>Take control with the EW-D Smart Assist App</h3>
Sennheiser’s EW-D Smart Assist App for iOS and Android can control every aspect of your wireless system from anywhere in the venue — no extra hardware required! Within the app, you can manage up to 16 channels of audio via Bluetooth. It’s also super easy to use, thanks to a user-friendly interface: simply touch a button and get at-a-glance battery monitoring or streamlined channel switching. With the EW-D Smart Assist App in your back pocket, you can perform in total confidence.
