Sennheiser EW-DX MKE 2-835-S SET Dual-Channel Digital Combo Wireless System with Omni Lavalier and Handheld Mic

Product Overview

The Sennheiser EW-DX MKE 2-835-S SET is a professional dual-channel digital UHF wireless system that pairs an MKE 2 omnidirectional lavalier microphone on a bodypack transmitter with an 835-S cardioid capsule on a handheld transmitter, all managed through a single 2-channel half-rack receiver. Built on Sennheiser's EW-DX platform, the system delivers 134 dB of dynamic range, AES 256 encryption, Bluetooth-based setup via the Smart Assist app, and up to 269 simultaneous channels within an 80 MHz tuning range. This is a complete, ready-to-deploy wireless solution for presenters, panel moderators, educators, and performing artists who require two distinct microphone types in a single coordinated system.

Product Description

The EW-DX MKE 2-835-S SET addresses a common real-world production requirement: two presenters or performers, each needing a different microphone type, managed through a single compact receiver. Channel one drives the SK EW-DX bodypack transmitter loaded with Sennheiser's MKE 2 subminiature omnidirectional lavalier, ideal for speakers who need hands-free operation and a discreet mic profile. Channel two drives the EW-DX handheld transmitter fitted with the MMD 835-S cardioid capsule and a built-in mute switch, suited for moderators, interviewers, or performers who prefer a traditional handheld form factor. The 2-channel EW-DX receiver occupies half a rack unit and provides two independent balanced XLR outputs with individual gain control.

At the core of the EW-DX platform is a 134 dB dynamic range — wide enough to capture both a whispered aside and a full-projection announcement without gain riding. The 80 MHz tuning bandwidth across 3,200 discrete frequencies, combined with the equidistant frequency grid and Link Density mode, enables the system to coexist with other EW-DX units and EW-D equipment in large multi-channel deployments. Intelligent switching diversity on the receiver continuously selects the strongest antenna signal, maintaining stable reception throughout a venue. Auto-scan identifies clean frequencies in the current RF environment and assigns them automatically, reducing setup time significantly. Bluetooth connectivity pairs each transmitter to the receiver via the Sennheiser Smart Assist app on iOS or Android, streamlining the entire synchronization workflow. For fixed installations or larger networked systems, the RJ45 port connects to Sennheiser's Control Cockpit or Wireless Systems Manager software. The transmitters accept either the Sennheiser rechargeable battery pack for up to 12 hours of operation or standard AA alkaline batteries for approximately 8 hours, providing flexibility for any deployment scenario. AES 256 encryption is standard across all RF transmissions.

Technical Specifications

Frequently Asked Questions

Q: What microphones are included in the EW-DX MKE 2-835-S SET?

The set includes an MKE 2 subminiature omnidirectional lavalier microphone mounted on a bodypack transmitter, and a handheld transmitter fitted with an MMD 835-S cardioid dynamic capsule with a built-in mute switch. A dual-channel EW-DX receiver is also included.

Q: Can both transmitters be used simultaneously?

Yes. The EW-DX 2-channel receiver manages both the bodypack and handheld transmitter independently and simultaneously, with separate XLR outputs for each channel.

Q: How do I sync the transmitters to the receiver?

Synchronization is handled via Bluetooth using the Sennheiser Smart Assist app on iOS or Android. This eliminates the need for IR line-of-sight and allows remote setup from across the room.

Q: How many channels can the EW-DX system support in a large venue?

With Link Density mode enabled, the EW-DX platform supports up to 269 transmitters simultaneously within a single frequency band, making it suitable for large-scale conference centers, arenas, and broadcast facilities.

Q: Is the EW-DX MKE 2-835-S SET compatible with existing EW-D equipment?

Yes. The EW-DX platform is backward-compatible with EW-D components, allowing mixed deployments where both generations of equipment operate on the same network and are managed through the same software.

Q: Does the system include encryption?

Yes. AES 256 encryption is standard on all EW-DX RF transmissions, securing the audio signal against interception. This is particularly relevant for government, legal, corporate, and broadcast applications.

Q: What is the operating range of the EW-DX MKE 2-835-S SET?

The system has a maximum operating range of approximately 328 feet (100 meters) line-of-sight. Actual range will vary based on RF environment, obstacles, and antenna placement.

Q: Can the receiver be powered over Ethernet?

Yes. The EW-DX receiver supports Power over Ethernet (PoE), which simplifies installation in fixed AV environments by eliminating the need for a separate power cable at the receiver location.
