Bộ xử lý số TOA DP-SP3

Đặc điểm nổi bật

DP-SP3 TOA là bộ xử lý tín hiệu số với 2 ngõ và và 6 ngõ ra khác nhau. Đặc tính của bộ xử lý kỹ thuật số đó là khả năng tinh chỉnh băng tần, Compressor, Delay. Và chức năng khác bao gồm cả ngõ vào PAD, ngõ ra chiết áp , ngõ ra MUTE, có thư viện đã thiết lập sẵn âm thanh cho loa TOA. Thiết bị được cài đặt, cấu hình đơn giản thông qua phần mềm chuyên dụng trên máy tính và cáp LAN.
