4-Channel Acoustic Echo Canceller Card for Yamaha DME64N/24N

The MY4-AEC card provides 4 channels of acoustic echo cancellation for remote conferencing using Yamaha’s DME24N and DME64N 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 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.
