Sennheiser EW-DX SK-SKM-S BASE SET: Dual-Channel Digital Wireless System for High-Performance Audio

The Sennheiser EW-DX SK-SKM-S BASE SET is a professional dual-channel digital wireless microphone system designed for users who demand consistent, high-quality sound in live sound, corporate, worship, and educational environments. Operating in the 470 to 550 MHz UHF frequency range, this system gives you the flexibility and reliability to perform in even the most crowded RF environments.

This configuration includes a rugged half-rack EW-DX EM 2 dual-channel receiver, a handheld transmitter without a microphone capsule, and a bodypack transmitter without a lavalier mic. This allows you to select your preferred mic components based on your specific performance needs, offering complete customization and control.

With a massive dynamic range of 134 dB and a wide 80 MHz tuning bandwidth, this wireless system can handle everything from whisper-level speech to dynamic stage vocals with absolute clarity. You’ll have access to up to 3200 frequencies to find a clean channel, and thanks to Sennheiser’s equidistant tuning grid, you can run up to 134 mic channels at once without interference. When managing larger, more complex setups, activating Link Density Mode allows operation of up to 269 channels—perfect for major productions and large-scale events.

The handheld transmitter features a modular design that supports a wide range of optional mic capsules, so you can tailor your audio capture to your specific use case. It’s compatible with capsules like the MMD 935, MMD 945, MMD 835, ME 9004, and even the Neumann KK204, letting you switch between vocal styles, environments, and polar patterns with ease. The durable all-metal body offers a professional-grade build that’s made to last, while onboard mute and function buttons let you manage the unit directly during use.

Also included is a bodypack transmitter made with the same level of craftsmanship and versatility. It features a locking 3.5mm input jack that accepts lavalier mics, headset microphones, or instrument cables. The integrated e-Ink display remains visible even when powered off, helping you identify units quickly during setup. Power options include the BA70 rechargeable battery with up to 12 hours of runtime or standard AA batteries for up to 8 hours. Built-in charging contacts allow you to use the optional CHG 70N dock for convenient in-device charging.

At the core of the system, the EW-DX EM 2 receiver combines intuitive design with powerful functionality. Its front-panel OLED screen shows real-time status for RF strength, battery life, and audio output levels. Built-in Bluetooth makes it easy to sync transmitters wirelessly and control settings via Sennheiser’s Smart Assist app from up to 120 feet away. For larger and more networked installations, the receiver supports PoE and integrates seamlessly with Sennheiser’s Wireless Systems Manager and Control Cockpit software via its RJ45 port. Balanced XLR and unbalanced 1/4-inch outputs provide flexible connectivity options, and the front headphone jack with volume control allows for real-time monitoring.

As your audio system grows, the EW-DX line is ready to expand with you. Additional transmitters, including tabletop units like the EW-DX TS for gooseneck microphones or bodypacks with 3-pin LEMO connectors, are available separately. To improve signal strength and stability, consider upgrading the standard rear-mounted antennas to 1/2-wave dipole models, ADA active antennas, or the AWM wall-mount antennas. For multi-receiver configurations, the EW-D ASA antenna splitter lets you distribute a clean, centralized antenna signal across four receivers without introducing intermodulation issues.

This base set pairs seamlessly with high-quality microphone components such as the Sennheiser MMD 935B dynamic cardioid capsule, designed for natural vocal reproduction with excellent off-axis rejection. Compatible with multiple SKM transmitters, it’s ideal for live vocals and stage use. It’s easy to install, built to last, and includes a protective metal grille.

For discreet audio capture, the Senal OLM-2 lavalier microphone offers a compact solution with a locking 3.5mm connector that works perfectly with the included bodypack. It features a broadcast-quality electret condenser element with an omnidirectional pickup pattern for 360-degree sound capture. It’s great for spoken word, presentations, or interviews where clarity and invisibility are essential. The lav comes with a tie clip and windscreen to reduce unwanted noise and ensure stable placement.

Whether you’re outfitting a professional venue, upgrading your stage rig, or setting up a high-performance corporate AV system, the Sennheiser EW-DX SK-SKM-S BASE SET delivers the tools and technology you need to sound your best—no compromises.
