Half-rack (9,5') receiver for use with Evolution Wireless Digital handheld, bodypack and tablestand transmitters. The stationary two-channel receiver with switching diversity technology shall be for use with up to two companion transmitters as part of a digital wireless RF transmission system. The receiver shall feature Bluetooth Low Energy (BLE) at a frequency range between 2402 and 2480 MHz for remote controlling the devices via a control App for iOS and Android. The receiver shall feature an automatic frequency setup function with spectrum scan functionality in order to establish an equidistant frequency grid with 146 channels in standard mode and 293 channels in Link Density Mode. The audio frequency response shall be between 20 Hz and 20 kHz (-3 dB). Audio total harmonic distortion (THD) shall be ≤ -60 dB for 1 kHz @ -3 dBfs input level. Dynamic range shall be 134 dB. System latency shall be 1.9 ms. The receiver shall be menu-driven with an OLED display showing the current frequency, channel number, metering of RF level, metering of AF level, lock status, muting function, antenna switching diversity, app connection, gain, audio output level, menu and battery status for each of the two associated transmitters. An auto-lock feature shall be provided to prevent settings from being accidentally altered.

Focus less on the wireless and more on the audio. 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. Multiple hardware and software options create networkable solutions for nearly any stage or campus, while equidistant channel spacing, auto scan, and Bluetooth Low Energy sync automatically coordinate and set frequencies with the push of a button. Monitor your devices from a distance-even from your pocket-with tools like Sennheiser's Control Cockpit, Wireless Systems Manager, and Smart Assist app. The future of wireless is here. EW-DX takes the complexities out of wireless audio by employing sophisticated tools that streamline the setup and monitoring process. With the press of a button, Auto Scan automatically assigns channels using an equidistant tuning grid that allow you to pack more channels more reliably, without problematic intermodulation interference. Take control of the system from your mobile device via the Sennheiser Smart Assist app or utilize advanced software options like Wireless Systems Manager (WSM) and Sennheiser Control Cockpit for a detailed system view in complex, networked environments.
