ĐẶC ĐIỂM NỔI BẬT
Mo-đun xử lí tín hiệu VX-200SP là một Mô-dun ngõ ra hay còn được gọi là mo-đun dò tìm sự cố dây loa của hệ thống VX-2000 với tín hiệu kiểm tra đường dây loa dạng “pilot tone”. Mo-đun có kích thước 30.5 (R) × 132.6 (C) × 290.3 (S) mm, khối lượng 235g, ngoài ra thiết bị còn có 2 ngõ ra và 1 ngõ vào tăng âm:
– Ngõ ra điều khiển chiết áp ngoài có cổng kết nối dạng rời, rơ-le dạng không điện áp với dòng điều khiển: dưới 7 A (DC), trên 7 A (AC)
– Ngõ ra loa có cổng kết nối dạng rời, đường kính lõi cáp: AWG 24 – AWG 16
– Ngõ vào tăng âm VP-2064, VP-2122, VP-2241,VP-2421, FV-224PA, FV-248PA, đường kính lõi cáp: AWG 24 – AWG 16
Đây là Mô-đun dùng để gắn vào khung gắn thiết bị giám sát VX-2000SF và phát hiện trạng thái của đường dây loa như ngắn mạch, hở mạch thông qua tín hiệu “pilot”, và dây chạm đất. Kết nối điểm cuối cùng của đường dây với chân giám sát để giám sát đường dây loa, tuy nhiên trong trường hợp này chúng ta phải sử dụng cáp âm thanh có dây chống nhiễu.
