Sennheiser EW-DX MKE 2 SET Dual-Channel Digital Wireless System

The Sennheiser 509315 is a complete wireless audio package built for presenters, educators, corporate speakers, and performers who cannot afford to wrestle with dropouts or complicated setup. Inside the box you will find a rackmount receiver with two independent channels, a pair of bodypack transmitters, and two MKE 2 lavalier microphones that capture speech with natural warmth and clarity.

Because the system works on UHF frequencies and uses a digital transmission scheme, it delivers stable signals in spaces where radio traffic is dense. An auto-scan routine looks for open spectrum, assigns frequencies with an equidistant tuning grid, and lets you start talking or performing in minutes. The wide 88 MHz tuning range gives you room for large multi-channel rigs, while an impressive 134 dB input dynamic range accepts anything from a quiet whisper to a powerful vocal without the need for manual gain tweaking.

Each transmitter runs up to 12 hours on the included rechargeable batteries, so an all-day conference or a long theatre rehearsal is covered without battery swaps. Bluetooth connectivity allows quick adjustments from a smartphone or tablet, which is handy when the rack is difficult to reach during a live event. For venues that handle sensitive material, AES-256 encryption keeps the audio stream private and secure.

Whether you are fitting out a lecture hall, a boardroom, a house of worship, or a touring stage, the EW-DX MKE 2 Set offers the reliability and audio quality that professionals expect from Sennheiser, along with modern conveniences that make daily operation straightforward.
