TÍNH NĂNG – ĐẶC ĐIỂM NỔI BẬT CỦA LOA TOA BS-633A
Loa có công suất hoạt động 6W (dòng 100 V), 3 W (70 V line), củ loa hình nón 12 cm (5’’) , độ nhạy 91 dB (1 W, 1 m) cho âm thanh khá lớn, rõ ràng, chân thực, đặc biệt phù hợp với các ứng dụng âm thanh thông báo hoặc nghe nhạc nhẹ. Tần số đáp ứng từ 120 – 15000Hz, đảm bảo âm thanh được phát ra luôn sắc nét từ dải tần thấp – cao với tiếng bass trầm lắng, mạnh mẽ, âm cao trong sáng, rõ ràng.
Loa hộp treo tường TOA BS-633A có trở kháng: 100V line:1.7kΩ(6W), 3.3kΩ(3W); 70V line:1.7kΩ(3W), 3.3kΩ(1.5W). Trở kháng đầu vào của loa dễ dàng thay đổi bằng cách thay đổi vị trí biến áp ở phía sau của loa. Đây cũng là một trong những điểm khác biệt giải thích vì sao nhiều người lựa chọn TOA cho những ứng dụng âm thanh thông báo của mình.
Loa TOA BS 633A có một đầu vào kiểu push-type cho phép dễ dàng kết nối cáp với các thiết bị phát nhạc và dây dẫn cầu. Đặc điểm này giúp việc kết nối và sử dụng loa trở nên đơn giản, nhanh gọn và cực kì thuận tiện cho người dùng.
Một lưu ý dành cho bạn khi thiết lập hệ thống âm thanh thông báo với loa hộp TOA chính là việc lựa chọn amply phù hợp. Amply TOA với những thiết kế dành riêng cho ứng dụng âm thanh thông báo TOA là giải pháp được ưu tiên khuyên dùng.
Với kích thước nhỏ gọn: 173(R) × 195(C)× 101 (S)mm, trọng lượng thấp (780g), loa hộp TOA BS-633A cho phép lắp đặt nhanh và dễ dàng, treo hoặc gắn trực tiếp lên tường đồng thời việc vận chuyển rất thuận lợi.
Loa hộp treo tường TOA BS-633A chuyên dụng cho thông báo được sản xuất với thiết kế đơn giản, có dạng hình vuông cùng những đường bo tròn bên ngoài khỏe khoắn, chất liệu nhựa ABS cao cấp màu trắng nhạt mang đến cảm giác trang nhã, tinh tế đồng thời tôn lên vẻ thanh lịch, sang trọng của không gian lắp đặt.
Loa hoạt động tốt trong ngưỡng nhiệt độ từ -10 ℃ đến 50 ℃, phù hợp với khí hậu của Việt Nam, đáp ứng yêu cầu về độ bền tối ưu.
Lưu ý khi lắp đặt – sử dụng loa TOA BS-633A
– Vỏ ngoài của loa được làm từ chất liệu nhựa ABS chắc chắn, có độ bền cao song dễ bám bụi vì vậy người dùng cần lau chùi, làm vệ sinh loa thường xuyên.
– Loa hộp này áp dụng cáp: 600 V cáp nhựa cách điện (IV dây hoặc HIV dây); Dây đồng rắn: φ0.8 – φ1.6 mm (tương đương với AWG 20-14); 7-lõi dây đồng xoắn 0,75 – 1,25 m ㎡ (tương đương với AWG 18-16)
– Khi sử dụng loa hộp TOA Bs-633A trong hệ thống hội thảo TOA cần lựa chọn các thiết bị khác như amply, micro… cùng thương hiệu, có độ tương thích cao với loa.

Today, while I was at work, my sister stole my iphone and tested to see if it can survive a 40 foot drop, just so she can be a youtube sensation. My apple ipad is now broken and she has 83 views. I know this is totally off topic but I had to share it with someone!
