Sennheiser EW-D ASA (Q-R-S) Active Antenna Splitter

Overview
Digital transmission in the UHF spectrum offers significant improvements in range, reliability, and scalability. The Smart Assist App connects through Bluetooth Low Energy, making setup and operation convenient even at a distance. With auto scan, establishing reliable connections is quick and effortless. The system also boasts a high audio input dynamic range of 134 dB, eliminating the need for sensitivity adjustments and preserving every detail. Intermodulation is eliminated, allowing for channels to be evenly spaced 600 kHz apart. This, along with 56 MHz of tuning bandwidth, enables up to 90 channels to be used. Additionally, there are 2,240 selectable frequencies for fine-tuning, and the system can operate for up to 12 hours with a lithium-ion battery pack (sold separately) or up to 8 hours with AA batteries.

The Evolution Wireless Digital system is a versatile and feature-rich option for singers, speakers, and musicians. It can be easily managed and paired through the EW-D Smart Assist App, providing state-of-the-art live sound. This system sets a new standard in the industry, offering more dynamic range than any other wireless system currently available. Its equidistant tuning grid, previously only found in high-end Sennheiser systems, simplifies frequency coordination and contributes to its scalability and high channel count. With the Smart Assist App, users have full control at their fingertips, allowing for a fast and automated setup, access to all system settings, and remote monitoring from their mobile device. This system is a game-changer for both beginners and professionals, providing reliable and high-quality wireless performance.

Raising the bar

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

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.
