Receiver for wireless system Sennheiser EW-DX EM 4 Dante (Q1-9)

Sennheiser EW-DX EM 4 Dante (Q1-9) is a professional four-channel digital receiver designed for use with Evolution Wireless Digital series transmitters. It features a durable full-metal 19" rack-mount chassis, allowing easy integration into concert, theater, corporate, or educational setups.

The model supports an extended 88 MHz switching bandwidth and operates in two modes: Standard, allowing up to 146 channels, and Link Density, supporting up to 293 channels. The equidistant channel spacing prevents intermodulation and ensures stable signal even in crowded RF environments. The AutoScan function quickly analyzes the surroundings and selects the optimal operating frequencies.

The receiver is equipped with four network ports configurable for Dante® operation (Primary/Secondary). The integrated antenna splitter supports up to 16 channels, and Ethernet connectivity (IPv4/IPv6) allows convenient management via Sennheiser Control Cockpit, Wireless Systems Manager, or third-party systems. Remote control is available via the Smart Assist mobile app over Bluetooth® Low Energy up to 25 meters.

Audio quality is ensured by the proprietary Sennheiser Performance Audio Codec (SePAC), providing ultra-low latency transmission (1.9 ms) and a wide 134 dB input dynamic range, eliminating the need to adjust gain on transmitters. Data security is guaranteed with AES 256 encryption, essential for confidential presentations, events, or conferences.

Receiver control is performed via an OLED display, jog wheel, and intuitive buttons, with a headphone output and volume control for local monitoring.

Note: When purchasing individual wireless components, please check their frequency ranges to ensure proper system operation. EW-DX EM 4 Dante (Q1-9) operates in the 470.2 - 550 MHz frequency range.
