4-Channel Acoustic Echo Canceller Card for Yamaha DME64N/24N, MTX5-D and MRX7-D

The MY4-AEC card provides 4 channels of acoustic echo cancellation for remote conferencing using Yamaha’s DME24N/DME64N/MTX5-D/MRX7-D digital mixing engines. As well as the echo cancellation function, the MY4-AEC card also offers a noise reduction function which removes steady-state background noise such as air conditioning and projector fans etc. 
The card also has a feedback suppressor with 42 notch filters per channel to aid the suppression of feedback in PA systems. Any of the 8 internal mic/line inputs of the DME24N, MTX5-D and MRX7-D can be routed to the MY4-AEC. In the case of the DME64N, any of the MY card slots or CASCADE bus can route to the MY4-AEC. The AES/EBU inputs and outputs (with sample rate conversion) can route to either the MY4-AEC or be used independently in a DME design.

4ch Adaptive Echo Canceller

The MY4-AEC has 4 channels of adaptive echo cancelling which can automatically find the appropriate setting of AEC according to the environment and the equipment being used. It can be used for multi-location meetings and in large conference rooms. 
Thanks to its very long 'tail length' (delay time), the MY4-AEC can remove very long delays (max 400ms) and can provide clear sound even when used in very large rooms or for long distance conferencing. As DME/MTX5-D/MRX7-D units are easily connected into PA systems, it also makes a noticeable difference in very large rooms where sound reinforcement is required and remote participants are involved.

HD Sound Quality

Web-based remote conferencing is becoming more popular and the sound quality is better than former systems utilizing telephone lines. The MY4-AEC can support a wide frequency range (20-20kHz) ensuring a natural sound for conversation.
The sampling rate of the MY4-AEC is 48kHz but it can be used in 96kHz systems by reducing capacity from 4 to 2 channels (96kHz mode is only available for DME64N/DME24N).

4ch Feedback Suppressor and Noise Reduction

In large conference rooms or auditoriums where microphones are used with a PA for voice amplification, the MY4-AEC's 4-ch feedback suppressor employs 42 notch filter bands per channel. Each channel also has Width and Depth parameters that can be adjusted to achieve optimum level.
The MY4-AEC is also equipped with a powerful noise reduction function. Any constant, disturbing fan or air conditioning noise can be attenuated, further maximizing the performance of the echo canceller.

Additional 4ch AES/EBU I/O with Sampling Rate Converter

To facilitate the use of other digital equipment, the MY4-AEC card has 4ch AES/EBU I/O. The I/O ports have sampling rate converters ensuring easy connection to equipment with different sampling rates.

Easy Operation with DME Designer and MTX-MRX Editor

With DME Designer for DME24N/DME64N and MTX-MRX Editor for MTX5-D and MRX7-D it is possible to optimize the performance of all the Acoustic Echo Canceller parameters (In case of DME24N/DME64N, DME Designer V4.0 and compatible hardware required). 

To use with MTX-MRX Editor, the template files are provided for your simple setup. Template files are included with the download of MTX-MRX Editor.

MY4-AEC Component for DME Designer and MTX-MRX Editor

With DME designer and MTX-MRX Editor, you can easily optimize the performance of the Acoustic Echo Canceller parameters.

Acoustic Echo Canceller

The balance between echo reduction level and sound quality can be easily evaluated and maximised during installation.

Echo suppression is maximized by setting the Distance parameter to reflect the physical distance between microphone and loudspeaker.

Matrix Mixer

Multi-point conference systems are easily incorporated using the Matrix Mixer which allows up to 4 far-end inputs for each channel of AEC.

Feedback Suppressor

There are 42 notch filter bands whose width and depth parameters can be adjusted for best gain before feedback depending on the room acoustics. Each band will analyze suppression point automatically.

Noise Reduction

Any constant and disturbing fan or HVAC noise can be attenuated using the Noise Reduction feature.

Features

  • 24bit resolution, 4-in/4-out adaptive echo canceller
  • 4x Euroblock connectors
  • HD sound quality
  • 4ch feedback suppressor and noise reduction
  • Additional 4ch AES/EBU I/O with sampling rate converter

Excellent product and customer service

The service at ODYOWAVE is top notch. I only deal with them for most of my pro gear. All the other dealers have to take a back seat. Items come on time and in excellent brand new condition.
