In 2005 AKG has launched the very first Perception models – a completely new series of microphones showing legendary AKG Sound & Quality at an outstanding price level.
The brand-new Perception 820 Tube delivers real tube sound quality. It is not only the new flagship model of the Perception Series but also raises the bar in its class of affordable tube microphones.
In contrast to many other affordable tube microphones, the Perception 820 Tube delivers real tube sound quality thanks to the dual one-inch large diaphragm capsule and the sophisticated ECC 83 dual-triode circuitry.
