Sennheiser EW-D ASA (Q-R-S) Active antenna splitter (dual 1;4) with DC power distribution for EW-D

Sennheiser EW-D ASA The Sennheiser EW-D ASA is an Active Antenna Splitter designed for use with Evolution Wireless Digital systems. Built for the UHF frequency range of 470–694 MHz, it forms part of Sennheiser's digital wireless ecosystem, engineered to deliver a more dynamic, reliable, and scalable signal distribution solution for professional wireless microphone setups. Raising the Bar Evolution Wireless Digital breaks the boundaries by providing more dynamic range than any wireless system currently on the market. It automatically secures the most reliable signal in a matter of seconds and is scalable up to 90 channels thanks to 56 MHz of tuning bandwidth — placing this wireless system in a class of its own. Equidistant Spacing — Simpler Than It Sounds Evolution Wireless Digital features an equidistant tuning grid previously found only in Sennheiser's 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, while also contributing to the system's scalability and impressively high channel count. An Engineer in Your Pocket The power of Bluetooth Low Energy puts full control right in the palm of your hand with the Sennheiser Smart Assist app. Users can take advantage of a remarkably fast automated setup, mobile access to every system setting, and the added benefit of remote monitoring — all from an Android or iOS device, saving time and energy while performing with confidence. Why We Love This Our gear experts love the EW-D ASA because it removes the headaches of wireless coordination. Digital transmission eliminates noise, interference, and static bursts, so performances stay clean. Automated setup means less time troubleshooting and more time playing. With up to 2,240 selectable frequencies and 90 channels available, bands and touring acts can scale up without frequency conflicts. And with the Smart Assist app, musicians get remote monitoring and full control from their phone, keeping them confident and in charge mid-show.
