Sennheiser EW-DX EM 2 Digital Half-Rack 2-Channel Receiver, R1-9 520-607.8 MHz

Sennheiser EW-DX EM 2 Digital Half-Rack 2-Channel Receiver, R1-9 520-607.8 MHz

Sennheiser EW-DX simplifies your professional workflow by utilizing refined technologies to deliver a digital UHF system that can be scaled with ease. With its advanced feature set and hardware options, classrooms, corporate campuses, and live performance productions benefit from a network-ready system that is designed to integrate seamlessly. AutoScan quickly assesses your environment and uses equidistant channel spacing to deploy frequencies while tools like Sennheiser’s Control Cockpit, Wireless Systems Manager, and Smart Assist App allow you to monitor your system remotely.

Key Features

• Two-channel digital half rack (9.5”) in rugged metal housing
• Up to 88 MHz switching bandwidth
• Low latency of 1.9 ms wireless transmission thanks to proprietary Sennheiser Performance Audio Codec (SePAC)
• 134 dB input dynamic range - no need to set gain on your wireless transmitters at all, thanks to proprietary Sennheiser Performance Audio Codec (SePAC)
