Presentation
The Sennheiser EW-DX EM 2 Dante R1-9 is a two-channel, half-rack 9.5″ digital wireless receiver designed for use with transmitters from the Evolution Wireless Digital range. It is distinguished by its ability to integrate audio directly into high-resolution Dante® networks, accepting sampling up to 96 kHz in 24 bit.
This model covers the R1-9 frequency range (520 - 607.8 MHz), enabling flexible RF operation in geographical areas compatible with this band. The extended switching bandwidth of 88 MHz makes it easy to allocate a large number of RF channels without intermodulation, with up to 146 channels in standard mode and 293 in Link Density mode.
Wireless transmission benefits from robust AES 256 encryption and very low system latency (1.9 ms), essential for demanding broadcast or live applications. Its metal construction and PoE (IEEE 802.3af) or DC power supply make the R1-9 suitable for professional technical environments.
