Powerful, noise-free, latency-free

Digital signal processing offers a latency of just 1.9 ms, ensuring your playing feels completely natural. The system operates in the UHF range of 630–662 MHz (S4-7), ensuring a stable connection with a long range—significantly more reliable than many 2.4 GHz systems.

The transmitter’s 134 dB dynamic range captures every nuance of your playing—from the quietest fingerpicking to the loudest power chords. And all without noise, interference, or glitches.

App-Controlled Setup – Fast & Easy

With the EW-D Smart Assist app, the system is ready to go in no time. The app handles frequency management, pairing, and configuration—without any cumbersome menus on the device itself. This leaves more time for what matters most: your performance.

The automated setup ensures reliable connections with minimal effort, while the app offers full control over all functions—ideal for solo artists or technicians who need to react quickly.

Long-lasting operation with rechargeable or standard batteries

The included lithium-ion battery pack provides up to 12 hours of runtime. Alternatively, the transmitter can also be powered by standard AA batteries (up to 8 hours). This ensures you’re fully prepared for any stage situation—no matter how long the set lasts.

Scalable system with high frequency density

With up to 2,240 selectable frequencies within a 56 MHz bandwidth, the EW-D CI1 SET supports up to 90 channels simultaneously. This allows the system to be easily integrated into larger setups—whether in bands, at festivals, or in the professional AV sector.
