Bộ xử lý kỹ thuật số Extron DMP 128 là bộ trộn âm thanh 12×8 có Extron ProDSP, trộn tự động, có sẵn AEC cộng với Dante mạng âm thanh. FlexInputs để xử lý các kênh Dante thay cho đầu vào micro/đường truyền cục bộ và giao diện điện thoại tương tự POTS. DMP 128 series cung cấp cách tiếp cận cấu hình cho DSP giúp đơn giản hóa việc trộn, định tuyến, hội nghị và tối ưu hóa phòng.
