MA-300/400/600/800/1000/1200

專業功放MA-係列

MA-300/400/600/800/1000/1200
完善的保護電路保障了整機的穩定性;
      1)溫控保護電路;更好地解決了因過熱而產生致命損壞,當機內溫度達到90度時,功放會自動切斷與揚聲器的連接,溫度回到80度,則自動回複正常工作。
      2)短路功能保護:能保證在操作等情況下,保護機器本身及揚聲器安全
      3)內置限幅器:時一種非常有效防止損壞揚聲器的保護電路,當功放發生削波過載時
會產生大量的諧波能量,能使揚聲器過載而損壞,本款功放專門設置了一個非線性比較器,一旦出現信號被削波,立刻可以調整功放電路的工作狀態,直至消除削波為止。
      優良的音頻信能;具有優質的信號轉換特性,它具有非常小的諧波失真(THD)互調失真(SMPTE-IM),瞬間互調失真,演繹自然純真的音質。
輕觸開機軟件啟動,防浪波衝擊保護。

 

 

Professional power amplifier MA - series
MA - 300/400/600/800/600/800
Perfect protection circuit to ensure the stability of the machine;
      1) temperature control protection circuit;To better solve the fatal damage due to overheating, when the internal temperature of 90 degrees, speaker and amplifier will automatically cut off the connection, temperature to 80 degrees, automatically return to normal work.
      2) short circuit protection function: can guarantee in cases such as the operation, protect the security of the machine itself and the speaker
      3) built-in limiting device: a kind of very effective to prevent damage to the speaker protection circuit, when the power amplifier clipping overload occurs
      Will generate lots of harmonic energy, can make the speaker overload and damage, this kind of power amplifier specially set up a nonlinear comparator, once appear signal is clipping, can adjust the working state of the power amplifier circuit, immediately until eliminate clipping.
Excellent audio letter can;High quality signal characteristics, it has a very small harmonic distortion (THD) intermodulation distortion (SMPTE - IM), instant intermodulation distortion, deduce natural pure sound quality.
       Touch your boot software startup, storm wave impact protection.
