Sennheiser EW-D ME2/835-S SET (Q1-6) Digital Wireless Combo Microphone System (Q1-6: 470 to 526 MHz) - 508770

Product Overview

The Sennheiser EW-D ME2/835-S SET (Q1-6) is a professional dual-transmitter digital wireless system operating in the 470–526 MHz frequency band, designed for presenters, lecturers, performers, and houses of worship requiring reliable UHF wireless audio. This combo set pairs a bodypack transmitter with the ME 2 omnidirectional lavalier microphone and a handheld transmitter fitted with the MMD 835-S cardioid capsule, giving users the flexibility to switch between discreet hands-free pickup and confident on-stage vocal delivery. The single-channel EW-D receiver provides intelligent switching diversity reception and connects to standard rack enclosures, making it equally suited to fixed installations and touring rigs. Built on Sennheiser's Digital 6000/9000 platform architecture, the EW-D delivers 24-bit audio quality with 134 dB of dynamic range at a price point accessible to educational, corporate, and house-of-worship markets.

Product Description

At the heart of the EW-D ME2/835-S SET is the Evolution Wireless Digital platform, which replaces analog companding with true digital RF transmission to deliver clean, artifact-free audio regardless of input level. The ultrawide 134 dB dynamic range eliminates the need to set transmitter input sensitivity, meaning you can move from a quiet speaking voice to a loud vocalist without touching a gain control. The Q1-6 frequency block covers 470–526 MHz, a 56 MHz-wide band that provides 2,240 tunable frequencies on an equidistant grid derived from the higher-end Digital 6000 series — removing the intermodulation calculations required with legacy analog systems. Up to 90 simultaneous channels can coexist within this band, making the EW-D appropriate for large conference facilities, performance venues, or multi-stage event productions where dozens of microphones must operate side by side. Bluetooth connectivity links the transmitters and receiver to Sennheiser's Smart Assist mobile app, enabling channel assignment, gain adjustments, battery monitoring, and system notifications from a smartphone or tablet without walking to the rack. Transmission range reaches up to 328 feet (100 m) line of sight, providing ample coverage for most auditoriums and performance spaces. The bodypack transmitter accepts AA alkaline batteries for up to 8 hours of runtime, or the optional Sennheiser rechargeable battery pack for up to 12 hours. The ME 2 lavalier capsule is omnidirectional with a 5.2-foot cable, appropriate for clip-on placement on a lapel, tie, or headset adapter. The included MMD 835-S handheld capsule module reproduces the well-regarded MD 835 cardioid polar pattern, delivering strong off-axis rejection suited to speech reinforcement and live vocals. The 1 RU receiver outputs balanced audio via XLR and provides -3 to +42 dB output gain adjustment in 3 dB steps, covering the input requirements of virtually any mixer or audio processor.

Frequently Asked Questions

Q: What is the difference between the Q1-6, R1-6, and R4-9 frequency variants of the EW-D ME2/835-S SET?

All three variants are mechanically and functionally identical — same transmitters, receiver, microphones, and feature set. The only difference is the RF frequency band. Q1-6 covers 470–526 MHz, R1-6 covers 516–558 MHz (approximately), and R4-9 covers 552–607 MHz. Choose the variant that falls in a clean, license-compliant frequency range for your geographic location. In the United States, the 470–526 MHz range (Q1-6) is generally available for wireless microphone use, but always verify current FCC frequency allocations for your region before purchasing.

Q: Can I use both the bodypack and the handheld transmitter at the same time?

No. The EW-D receiver in this set is a single-channel receiver, so only one transmitter can be active at a time. The combo set gives you the flexibility to choose the best transmitter for each situation — the bodypack with lavalier for hands-free use, or the handheld for vocal performance — but you must power off one before using the other on the same channel.

Q: Do I need RF coordination expertise to set up the EW-D system?

No. The equidistant tuning grid and auto-scan feature on the EW-D receiver handle frequency selection automatically. The receiver scans the local RF environment, identifies a clean channel, and syncs the transmitters via Bluetooth through the Smart Assist app. No intermodulation calculations or spectrum analyzer are required for standard deployments.

Q: How many EW-D systems can operate simultaneously in the Q1-6 band?

Up to 90 simultaneous channels can be deployed within the 56 MHz Q1-6 band (470–526 MHz). This is made possible by the equidistant tuning grid, which spaces frequencies evenly to eliminate third-order intermodulation products that limit channel counts in traditional analog wireless systems.

Q: What mixer input does the receiver connect to?

The EW-D single-channel receiver provides a balanced XLR output. The receiver gain is adjustable from -3 to +42 dB in 3 dB steps to match the input requirements of any mixing console, audio interface, or PA system.

Q: Is the ME 2 lavalier suitable for outdoor use or high-humidity environments?

The ME 2 is designed for professional use in a wide range of environments. For extended outdoor use or high-perspiration applications, Sennheiser recommends using a foam windscreen and appropriate cable management. The microphone is not rated as waterproof.

Q: Can I replace the MMD 835-S capsule on the handheld transmitter with a different capsule?

Yes. The EW-D handheld transmitter uses Sennheiser's standard MMD capsule adapter system, which is compatible with a wide range of Sennheiser MMD capsule modules. This allows you to swap in a different polar pattern or capsule type — such as a supercardioid or condenser capsule — without replacing the transmitter body.

Q: What is included in the box with the EW-D ME2/835-S SET (Q1-6)?

The set includes the EW-D single-channel receiver, the EW-D SK bodypack transmitter with ME 2 omnidirectional lavalier microphone (5.2 ft cable), the EW-D handheld transmitter with MMD 835-S cardioid capsule, an AC/DC power adapter for the receiver, and mounting hardware for rack installation.
