The attenuator is located in the special aluminium box (10 mm thick walls) what provides perfect shielding and thanks to the special design it also absorbs the vibrations. The Hyperion P1 is a Class-A preamplifier and was designed to avoid ANY global feedback. The attenuator as well as the electronic part are installed on anti-vibration pads (columns) which contributes to the overall elimination of vibrations. The analogue part is separated from the power part by a solid aluminium wall (10 mm thick) which contributes to the elimination of interference. The attenuator control is galvanically separated via optical drivers.
