Advanced Features
The EW‑DX is a digital radio mic system that features an extended 88 MHz switching bandwidth and delivers intermodulation‑free operation across multiple channels with secure AES‑256 digital encryption. These compact half‑rack dual receivers pair with Evolution Wireless Digital handheld and bodypack transmitters. They deliver twice the channel count within the same footprint as the previous generation of Sennheiser radio mics, which have formed the backbone of the IPS radio mic range for many years.
Although the models we stock lack Dante connectivity, they offer Ethernet control via Sennheiser Control Cockpit or Wireless System Manager. You can also use the Ethernet connection to create a redundant power supply through PoE.
The AutoScan feature quickly scans the environment and deploys frequencies with equidistant channel spacing, even for users without RF expertise. The units also include a Link Quality Indicator (LQI) that displays link quality independently of RF levels. Audio outputs are available on the rear via balanced XLR or unbalanced TRS jack, and a convenient local headphone output sits on the front panel.
