One Van den Hul The Black Hole audio power filter in a fantastic, like new condition. Bearing ultimate performance and reliability in mind, the filter was designed entirely fresh from the ground up and has been fit with the highest quality components. The Black Hole is a heavy and powerful four outlet passive mains filter which core design is based on entirely new technology and concepts. It provides high-end audio, video and mixed setups with perfectly clean mains power and is capable of handling up to 1800 Watt total connected. Acting as the best thinkable external firewall solution, The Black Hole effectively deals with all potential mains related A/V quality degradation mechanisms, this whereas most other passive mains filter units only crudely deal with a few. It cuts mains-borne noise and spikes, removes direct current and provides high frequency isolation from mains. Ultimate performance is furthermore delivered by a highly advanced circuit design which is resonance-free and adds our unique Dynamic Noise Absorption (DNA) concept. It is the original European 230 volts version with four schuko outlets (two 2A low power intended for pre-amps, CD-players, streamers and two 8A high power intended for power amplifiers). Serial number is 010043E. Retail price is 2.900 euro. The original box and manual are included. Check our other listings for more interesting items. Free shipping worldwide!
