Part of the ADECIA series of Dante-networked wireless conferencing components, the black Yamaha RM-WDR is a wireless tabletop microphone designed to be positioned on a conference table to provide a comfortable audio conferencing experience with no configuration needed. The mic captures consistent, crystal-clear audio for highly intelligible speech and natural-sounding conversations in conference calls, video conferences, remote collaborations, and distance learning. The microphone is well suited for small- to medium-sized training rooms, conference rooms, classrooms, multipurpose rooms, or boardrooms.

The mic supports the 1.9 GHz DECT standard with 256-bit AES encryption, providing safe and secure transmission at a range up to 164'. A mute button with green and red LED indicates the microphone's on or off status, while a second three-color LED shows the battery status. The unidirectional polar pattern provides a 120° angle of acceptance, focusing audio capture on the speaker for less unwanted background sound. A built-in lithium-ion rechargeable battery powers the mic and built-in transmitter for up to 20 hours, enough time for even the lengthiest discussions.

Compatible with Dante, the RM-WDR is used with the RM-WAP wireless access point and the RM-CR audio processor (both available separately), which offers an easy setup with auto configuration. Up to eight microphones can be used for scalability. Clear voice quality is achieved using adaptive echo canceller, auto-gain control, noise reduction, and dereverberation processing.

Related Questions and Answers

Q: 1. Is there a way to listen to the audio while simultaneously recording with the XLR adaptor on a DSLR?

A: Generally the answer is no. The AVX, like most wireless systems, outputs a mic level signal. It is not designed for direct audio monitoring. If you want to monitor the signal you have a couple of options: Use the headphone output from your DLSR (if it has one), use a mixer between the AVX wireless receiver and the DSLR ( JuicedLink, Beachtek,and Sound Devices offer a great range of products, these usually have a built in headphone amplifier for audio monitoring), or use a field video monitor that includes audio monitoring from the camera's HDMI port. I would just double check if your DLSR is actually sending audio down the HDMI port.

Q: 2. i just got my AVX system, every time i turn it on i have to pair them is this normal?on my older sennheiser and sony system i just pair them once and it's good til i have to change channels.

A: The AVX system is digital, and it is recommended to pair the transmitter and receiver whenever you are in a new environment, but they should stay paired, even when turned off and back on again. You may want to check with Sennheiser to see if there is a technical issue with your particular wireless system.

Q: 3. It should be noted, that while this system includes 2 transmitters, only 1 can be used at a time. -- Does this mean I can't use two lavs at the same time, or one lav and one handheld during a shoot?

A: The transmitters work independently. You can use two of the mics at the same time in any combination, so long as you can accept two lines of audio into the device you are using.

Q: 4. How well suited is this for live events, such as a ballroom with a presentational speaker? Will lots of people in the room interfere with the signal if the tech table is in the back? Will the automatic gain control affect the person trying to bring the voice up on the board?

A: The AVX system is very good, but it has a short operating range of up to 98 feet (line of sight) and you may experience problems with signal dropout if the receiver is too far from the transmitter or if anything blocks the signal path between the transmitter and receiver. If you want to have the same flexibility as the AVX combo system to be able to switch between lavalier and handheld mics, you may like the ew 100 G4 combo system which includes the ew 112P wireless lavalier system combined with an SK 100 plug-on transmitter that will attach to any dynamic mic with an XLR output connector, allowing you to select your own handheld mic. If you prefer the Sennheiser wireless handheld mic, you can purchase an SKM 100 G4 Handheld Wireless Microphone Transmitter with No Mic Capsule (B&H # SESKM100G4A1) with a Sennheiser MMD 835 Cardioid Dynamic Capsule (B&H # SEMMD835) and combine it with an ew 112P G4 lavalier system (B&H # SEEW112PG4A1). Please contact us if you would like further assistance.

Q: 5. Is there a way to listen to the audio while simultaneously recording with the XLR adaptor?

A: Headphones from your camera.

Q: 6. How does audio quality and range compare with conventional Sennheiser Evolution series wireless? The compact receivers are attractive, but I am concerned about apparent lack of lack of traditional wireless features like diversity receivers.

A: The AVX digital wireless systems are compander-free and offer pristine audio reproduction. The transmitter outputs at 100 mW (average) so should be minimal to zero trade off with regards to range.

Q: 7. Does this kit come with the battery packs?... one pack for each unit? -Thanks!

A: It comes with 1 battery for each transmitter/receiver. Extra transmitter batteries are part # SEBA30 and receiver batteries are part # SEBA20.

Q: 8. is one of the Lav's an MKE2?

A: They are both ME 2's

Q: 9. do you need a base station for this to work?

A: No, the Eartec UltraLITE Single Full-Duplex Wireless DECT Intercom System with 4 UltraPAKs and 4 Cyber Headsets does not require use of a base station like the Eartec HUB. This system uses an UltraLITE Master Headset, which has the transceiver built into the earcup, and it is used to control the four included UltraPAK Remote Beltpack Radios and the Cyber Headsets that are connected to them.

Q: 10. Can I use it on Phoenix Octopus device for an additional Microphone?

A: Unfortunately not. The Phoenix Audio MT454-PA Octopus USB Base Unit is no longer available. Also the Phoenix Octopus is for Audio Conferencing and full Duplex Communication. The Sennheiser AVX you are referring to is two separate wireless mic's. With XLR receiver's that plug right into the camera. It was designed primarily for "run and gun" type of work.
