4-channel acoustic echo canceller Mini-YGDAI card for Yamaha DME, MTX and MRX processors, with built-in feedback suppressor, noise reduction and AES/EBU I/O.
The MY4-AEC is a 4-channel acoustic echo canceller in Mini-YGDAI card format, designed for videoconferencing and speech lift applications within Yamaha DME or MTX5-D processor systems. It removes room echo from microphone signals so that far-end callers hear only the speaker's voice, not the reflections from the room's loudspeakers.
In addition to echo cancellation (up to 60 dB), the card includes a feedback suppressor, noise reduction (up to 17 dB) and a matrix mixer, providing a complete signal conditioning chain in a single card.
Up to 60 dB of acoustic echo cancellation suppresses the loudspeaker signal from microphones, ensuring intelligible speech for far-end conference participants.
Up to 17 dB of background noise reduction attenuates HVAC, projection fans and other constant-spectrum noise from the microphone signal.
Integrated feedback suppressor detects and notches out feedback frequencies in real time, providing an additional layer of protection in high-gain speech-lift systems.
Built-in matrix mixer enables flexible routing of AEC-processed channels to multiple outputs within the host DME or MTX5-D processor.
