HIFI功率放大器
   是英語High-Fidelity的縮寫,直譯為高保真,其定義是:與原來的聲音高度相似的重發設備。Hi-Fi功放用于欣賞音樂,使用者追求的是盡可能的原汁原味, HIFI功率放大器在重放過程中,對聲音信號各項指標不失真地放大、處理,以還原聲源的本來面貌,強調的是原汁原味,專門用于欣賞音樂。Hi-Fi功率放大器和普通功率放大器相比對原始音色的還原程度更高,從參數上來說,要求信噪比高,一般超過100dB,頻率響應超過20HZ~20KHZ(±0.5dB),諧波失真要求小于0.01%,動態范圍也要大,其音頻信號衰減少、精確性和準確性更高。






AV功率放大器
  AV功率放大器是專門為家庭影院用途而設計的放大器,在前級電路中增設了視頻的輸入選擇、處理和聲場處理電路, 相應聲道的功率放大線路,就構成了基本的AV功放。其設計的重點是配合視覺效果營造出理想的聽音環境,創造逼真的方位感、臨場感和震撼感。在乎表現對白的清晰度和視聽環境的大動態大“爆棚”效果,還原或模擬出聲畫合一的聲場定位,制造出逼真的聲場氣氛。
