Equalizer DBX 2231

Equalizer DBX 2231

Equalizer DBX 2231 là thiết bị âm thanh ánh sánh sân khấu không thể thiếu trong bất kì một buổi hòa nhạc hay hội trường chuyên nghiệp nào, nó giúp tín hiệu âm thanh được trong trẻo và rõ ràng hơn. DBX 2231 có phạm vị hoạt động với độ nhạy từ 0dBu đến + 24dBu.

Tính năng nổi bật: 

• Revolutionary instant encode/decode Type III® Noise Reduction in-circuit at the push of a button. Increases S/N ratio by up to 20dB
• Patent-pending PeakPlus™ Limiter threshold range from 0dBu to +24dBu (off) can transparently tame the wildest hits or the subtlest nuances of any signal
• Four segment LED bargraph for BOTH Gain Reduction AND Output Level
• Status LEDs offer visual feedback for all settings on the front panel.
