Evolution Wireless Digital: the arrival of accessible digital technology in the Evolution family
With Evolution Wireless Digital, Sennheiser applies its expertise in digital wireless to a modular system designed for stage and event use. The series follows a "workflow"-oriented philosophy: application integration, guided startup, and frequency organization to limit the usual constraints related to RF.
The system notably relies on a constant interval tuning grid (inspired by the brand's high-end digital ranges) to facilitate frequency deployment, reduce intermodulation issues, and make the whole setup easier to deploy, even without advanced RF expertise.
Who and what for: a receiver designed for stage, events, and installation
The EW-D EM R1-6 is a half-rack receiver designed to work with handheld transmitters and bodypack transmitters from the Evolution Wireless Digital family. It is perfectly suited for singers, speakers, sound technicians, service providers, and equipped venues (theaters, companies, cultural institutions) seeking a reliable wireless system that is quick to set up and easy to control.
Its rackable format naturally fits into a flight case, technical furniture, or control rack, while remaining suitable for configurations that need to evolve: adding channels, frequent reconfigurations, alternating between handheld and lavalier microphones depending on the event.
