Yamaha to Debut Acoustic Echo Canceller Card for DME24N/64N Digital Mixing Engines

[ATTACH=CONFIG]194602.vB5-legacyid=1559[/ATTACH]BUENA PARK, Calif.—Yamaha Commercial Audio Systems, Inc. will launch the new MY4-AEC (Acoustic Echo Canceller) card at InfoComm in Booth #823. A new high-performance conference system solution utilizing Yamaha AEC technology, the 4-channel MY4-AEC has a maximum echo cancellation time (tail length) of 400 ms. The card has a matrix mixer that is able to mix four different locations for reference inputs, enabling features for remote conferencing applications when using Yamaha digital mixing engines DME24N and DME64N in single or multi-point meeting situations.

The MY4-AEC card offers a 4-channel noise reduction function that removes background noise from air handlers, projector fans, etc. providing a clear, precise sound. The card also has a 4-channel feedback suppressor with 42-band notch filters that aid in eliminating feedback from PA systems. Each band will analyze suppression points automatically. The user can select the balance of echo reduction level and sound quality and can select early delay of distance between loudspeakers and microphones to maximize the echo suppression effect.

Both 2-channel AES/EBU inputs and outputs have sampling rate converters enabling easy connection to various digital products with different sampling rates. Acoustic Echo Cancellation processing can be fed from these inputs or any of the available I/O on the DME units. The MY4-AEC card functions at 48kHz and is compatible with a 96kHz-sampling rate when specific events require high-quality audio (channel capacity is reduced to two channels). The card features high-definition sound with a frequency range of 20Hz-20kHz.

With Yamaha DME Designer, the customer can easily edit the parameters of the Acoustic Echo Canceller. DME Designer V4.0 will also launch at InfoComm with several new functions including Partial Recall. Both the DME24N and DME64N are compatible with the new version of DME Designer V4.0 software and are required for using MY4-AEC cards.

“By using the new MY4-AEC card with a DME product, A/V contractors will be able to maximize corporate boardroom and meeting room control functions in one or more locations,” states Marc Lopez, marketing manager, Yamaha Commercial Audio Systems, Inc. “And, with no compromise in sound quality.”

The MY4-AEC card and DME Designer V4.0 will be available in the fourth quarter of 2011. The MY4-AEC card has a targeted MSRP of $1,600, and DME Designer V4.0 will be available via free download.
