The Sennheiser EW-D ME2 SET with ME 2 Omnidirectional Lavalier combines pristine 24-bit digital audio with an impressive 134 dB dynamic range, equidistant tuning grid, and automated Bluetooth set up App for your phone to create a professional rackmount wireless microphone system that anyone can use. Though easy to set up and simple to operate, the system's pro-level feature set is well equipped to handle the needs of both first-time and experienced users alike, including presenters and lecturers working in business and educational settings, clergy in houses of worship, and live performers in theaters or on musical stages.

The EW-D's ultrawide dynamic range means that input-sensitivity adjustments on the transmitter are not required. Based on the company's higher-end Digital 6000/9000 wireless systems, the equidistant tuning grid removes the need for frequency coordination and enables you to operate up to 90 mic channels simultaneously. The UHF transmission greatly enhances range (up to 330') and the wide 56 MHz bandwidth gives you the ability to find a clean channel from 2240 available frequencies.

Intelligent Switching Diversity offers effective protection against RF interference, and the ultralow 1.9ms latency eliminates any noticeable lag when performing live. Additionally, Bluetooth connectivity enables seamless pairing and remote control from your phone via the Smart Assist App. All these features allow the EW-D to automatically handle mic levels and secure the most reliable signal for you in a matter of seconds—without the hassles that can make using a wireless system challenging.

This EW-D ME2 SET is configured with a single-channel EW-D EM receiver, an unobtrusive, ME 2 omnidirectional lavalier mic optimized for speech intelligibility, and a robust, lightweight EW-D SK bodypack transmitter, featuring a metal housing well suited for daily use on stage.

The transmitter pairs with the receiver via Bluetooth Low Energy from up to 120' away, enabling you to quickly pair the mic directly from the stage without having to bring it close to the receiver. The bodypack provides up to 8 hours of operation on two AA batteries or 12 hours with a BA 70 lithium-ion rechargeable battery pack (available separately). The L70 USB dual-charging station (available separately) is required for the BA 70 batteries.

The half-rack EW-D EM receiver with removable antennas is housed in a rugged, all-metal chassis built to withstand the rigors of professional use. It can either sit on a tabletop or be rackmounted for portable rigs and permanent A/V installs.

The receiver features a high-contrast, black-&-white OLED display that uses a streamlined menu system with a dedicated Escape button for quick menu navigation, even in low-light situations. The auto-scan function automatically seeks out the cleanest available frequency for you. If you prefer, you can also configure, control, and operate your system via Bluetooth, using the Smart Assist App installed on your iOS/Android phone/tablet—within a 120' range.

Note: The EW-D digital system is NOT backward-compatible with previous evolution analog systems.

Related Questions and Answers

Q: 1. Will the Sennheiser BA 70 Rechargeable Battery Pack for EW-D Bodypack and Handheld Transmitters also work for the handheld mic?

A: Yes, the Sennheiser EW-D SKM-S Digital Wireless Handheld Transmitter can be used with the Sennheiser BA-70 rechargeable battery pack.

Q: 2. I want to mic a maximum of 12 performers with EW D. Do I need a variety of frequency bands? (4 each to cover 470 -600Mhz?)

A: You will be able to have a maximum of 90 transmitters per band, so if there is not significant interference in your area it should be alright to keep the same band for all systems.

Q: 3. produces lot of hissing noise during recording, even in very silent environments? This is not normal, but any workarounds ?

A: There will be a high noise floor (background hiss) if the gain is set too high, especially when recording to a DSLR. This is because DSLRs and mirrorless stills cameras have generally poor mic preamps. Here's how to minimize noise: On the AVX receiver, turn the output gain to 2 bars (out of the 4). On the camera, set the audio to manual gain and set it to only 1 notch above zero. This will minimize the camera's noisy preamp's effect. If your camera feeds phantom power, turn it off and use a mic level input. That should do it.

Q: 4. Can I add handheld microphones?

A: This is a single channel receiver, you can use a handheld with it as long as it's made by Sennheiser and it runs in the same frequency, however you wont be able to use both the lavalier and handheld at the same time.

Q: 5. Does the AVX system work worldwide?

A: The Sennheiser AVX-ME2 SET Digital Camera-Mount Wireless Omni Lavalier Microphone System (1.9 GHz) is made to work anywhere in North America, under current FCC regulations. It will also work in any region that allows you to use 1.9 GHz band for wireless microphones.

Q: 6. How can you tell the battery life of the receiver?

A: On page 7 of the manual, it states: "When the On/Off/Check button has been pressed, the LED display lights up green to indicate the remaining battery life of the receiver‘s BA 20 accupack (see page 24); when the AF Out button has been pressed, the LED display lights up red to indicate the audio output level (see page 27). When the right LED flashes red, the capacity of the receiver‘s BA 20 accupack is only sufficient for a maximum of 15 minutes of operation." https://www.bhphotovideo.com/lit_files/375153.pdf
