2009年在Frankfurt舉辦的ProLight+Sound/Musikmesse 上，AKG以很高的評價宣布了Perception話筒系列的產品?Perception 820 Tube。 
Perception 820 Tube為Perception系列家族中的一員，其產品還包括P 120, P 170, P 220以及 P 420。每個話筒都上的20分貝的衰減器和低阻濾器有利于擴增話筒在嗓音，銅管樂器，電吉他擴音器以及overhead miking等方面的功能。
AKG負責錄制和傳播產品的市場拓展Thomas Stubics說道：“AKG Perception 820 Tube話筒作為新一代的旗艦產品不僅僅帶來的是熱情和出色的聲音質量，更重要的是提高了這個價位管狀話筒的標準。” “與其他的管狀話筒相比，Perception 820 Tube表達了更加真實的管狀聲音質量。我們對于即將發布此產品的期望值非常的高，我們也非常高興能在Messe上發布Perception 820 Tube。”
Perception 820是由一個雙重一英寸的真正電容式大型振動膜包裹，一次傳遞清晰精確地信號，尤其適用于主音，銅管樂器，overhead miking以及其他的應用。
ECC 83雙三極管管狀電路以及輸出變壓器意在為飽滿的，流暢的立體聲制造出偶次諧波。遠程控制單元允許從*指向性，心形指向性到8字型指向性等9種不同的指向性中進行選擇。
另外，它也可以控制可切換的二階削低頻濾波器以及可切換的衰減器。此外，提起式接地開關可以防止不必要的雜聲。通過粉刷而進行陽極化處理的鋁制前面板以及全金屬外罩確保了防止外界無線電頻率的干擾。
由奧地利維也納設計制造的整個Perception生產線給AKG帶來了*的音質。其由堅固耐用的鋅鋁合成材料制成的不銹鋼格子屏幕就是*音質的良好保證。此外還有抵抗外界壓力的作用。
