The Sennheiser EW-DX EM 4 DANTE (Q1-9) is a flagship 19″ 1U full-rack, four-channel digital wireless receiver with integrated Audinate Dante® audio networking and an internal power supply, engineered for high-density enterprise A/V installations, broadcast studios, theaters, and touring productions operating in the Q1-9 Frequency Spectrum (470.2 – 550.0 MHz). Designed to deliver maximum channel density in minimal rack space, it features an integrated active antenna splitter allowing RF daisy-chaining for up to 16 wireless channels (4 receiver units) without external distribution hardware. Equipped with four flexible network ports, an expansive 88 MHz switching bandwidth, equidistant channel spacing (up to 293 channels in Link Density mode), and an ultra-low latency of 1.9 ms, it ensures maximum spectrum efficiency. Protected by AES-256 & Dante Media Encryption and controllable via Sennheiser Control Cockpit, WSM, and 3rd-party control plugins, it is available now at WG Electronic with fast UAE delivery.
High-Density 4-Channel Dante Wireless Receiver: Sennheiser EW-DX EM 4 DANTE (Q1-9)
The Sennheiser EW-DX EM 4 DANTE (Q1-9) sets the benchmark for high-channel-count digital wireless audio infrastructure. Purpose-built for large enterprise campuses, auditoriums, broadcast facilities, and theater productions, this 19″ 1U full-rack receiver houses four independent digital wireless receiver channels in a single rack enclosure—dramatically reducing space and power wiring requirements.
Operating across the clean Q1-9 Frequency Band (470.2 – 550.0 MHz), this flagship Dante-enabled unit from our Sennheiser evolution wireless series catalog offers an extraordinary 88 MHz switching bandwidth. Sennheiser’s intermodulation-free equidistant channel grid allows effortless high-density channel allocation without complex intermodulation calculations—supporting up to 146 channels in Standard Mode (600 kHz spacing) and up to 293 channels in Link Density Mode (300 kHz spacing).
