Tính năng của loa nén TOA CS 304
Loa nén dải rộng chống nước TOA CS-304 được thiết kế với vành loa (CS-64) và vành định hướng âm ổn định (CS-154/ CS-304) giúp nâng cao khả năng định hướng của loa. NGoài ra, loa còn sở hữu tâm loa phát trực tiếp hỗ trợ âm thanh đầu ra đạt chất lượng cao theo chiều ngang 90 độ.
Việc định hướng âm ổn định của loa kết hợp công suất hoạt động 30W cho chất lượng âm thanh cao, truyền xa và luôn đảm bảo tính chân thực, rõ ràng, chi tiết ở mọi dải tần số khác nhau.
Loa nén dải rộng chống nước TOA CS-304 có khả năng đáp ứng dải tần rộng từ 120 Hz – 15 kHz với độ nhạy đạt tới 98 dB (1W,1m), cho phép tái tạo âm thanh chính xác, chất âm hay, mang đến trải nghiệm âm thanh tốt nhất cho người nghe.
Một trong những điểm đặc biệt của hầu hết các mẫu loa nén TOA chính là việc người dùng có thể dễ dàng điều chỉnh trở kháng đầu vào của loa. Điều này không chỉ giúp cho âm thanh luôn đạt chất lượng mong muốn (tăng tính thuận tiện cho người dùng) mà còn tăng độ bền cho sản phẩm, mang lại giá trị kinh tế cao.
Loa có các mức trở kháng cụ thể như sau: 330Ω(30W), 500Ω(20W), 1kΩ(10W) ở đường dây 100V và 170Ω(30W), 330Ω(15W), 500Ω(10W), 1kΩ(5W) khi cắm đầu dây vào 70V. Trở kháng của loa có thể được điều chỉnh trước hoặc sau quá trình lắp đặt loa.
Loa nén dải rộng chống nước TOA CS 304 được sản xuất theo công nghệ hiện đại, sử dụng linh kiện được chọn lọc kĩ lưỡng và đáp ứng các tiêu chuẩn kĩ thuật – an toàn nghiêm ngặt của hãng TOA. Sản phẩm được đánh giá cao về mặt thiết kế:
+ Vành và phần vỏ loa được làm từ chất liệu nhựa ABS cao cấp có khả năng chống nước, chịu được thời tiết khắc nghiệt giúp nâng cao độ bền cơ học và chống va chạm.
+ Các bộ phận chịu lực được làm bằng thép không gỉ giúp loa chống được sự ăn mòn, hoạt động bền bỉ theo thời gian mà vẫn giữ được vẻ ngoài chắc chắn, đường nét khỏe khoắn.
+ Phù hợp với tiêu chuẩn chống bụi, nước, cháy IP-65. Người dùng có thể hoàn toàn yên tâm khi lựa chọn loa nén TOA CS-304, sản phẩm có độ bền cao, chống chọi được với thời tiết, khí hậu ở Việt Nam.
+ Loa có kích thước 366 (R) x 230 (C) x 272 (S) mm, trọng lượng 3.1kg nhờ đó việc lắp đặt, vận chuyển loa đơn giản, dễ dàng, thuận tiện.
