Sennheiser EW-DX MKE 2 SET Wireless Lavalier Microphone System, R1-9 520-607.8 MHz

Sennheiser EW-DX simplifies your professional workflow by utilizing refined technologies and decades of research 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 productions benefit from a network-ready system that is designed to integrate seamlessly. The system 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. In-device charging, 12-hour battery operation, and switching bandwidth up to 88 MHz are only a few more of the many features that make EW-DX the right tool for the job.

Key Features

• 134 dB input dynamic range - no need to set gain on your wireless transmitters at all, thanks to proprietary Sennheiser Performance Audio Codec (SePAC)
• AutoScan-feature quickly scans your environment and deploys frequencies with equidistant channel spacing - even without RF knowledge
• Network enabled for expanded remote control with Sennheiser Control Cockpit, Wireless System Manager (WSM - Available in 2023) and 3rd party media control systems via plug-in
• Remote control via Smart Assist App over Bluetooth Low Energy (BLE) at distances up to 25 meters (Available in 2023)
• Secure transmission of confidential content using AES 256 encryption
• Up to 12 hours of operation time with rechargeable lithium-ion battery BA 70 (included)
• Function buttons - control all the transmitter settings directly from bodypack including button lock function
• Persistent E-Ink display for “always on” information - parameters visible on screen even when taking out batteries
• Equidistant channel spacing to easily allocate intermodulation-free channels: Standard Mode with 600 kHz spacing for up to 146 channels; Link Density (LD) Mode with 300 kHz spacing for up to 293 channels
• Up to 88 MHz switching bandwidth
• Low latency of 1.9 ms wireless transmission thanks to proprietary Sennheiser Performance Audio Codec (SePAC)
  Digital audio trim
• Transmitters with charging contacts for in-device charging with CHG 70N charger (sold separately)
• Compatible with a wide range of Sennheiser lavalier and headset microphones with 3.5 mm jack plug connection
• Versatile charging options optionally available: CHG 70 N, L 70 USB, LM 6070 Module for L 6000 full rack charging station (Availability in 2023)
