A significantly oversized power supply brings audible benefits: the bass gains authenticity, the mids appear more effortless, and the overall dynamics increase. Music reproduction benefits in all areas from the more stable and cleaner power supply.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFilter Power Supply with Interference Protection Transformer\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eCentral to the achieved sound quality is the 30 VA toroidal transformer. This is designed as an interference protection transformer with a grounded shield winding and effectively filters common-mode interference components from the mains voltage.\u003cbr\u003eA decisive advantage of this interference protection winding is the drastic reduction of potential voltages between ground and earth: Instead of up to almost 100 volts – as with power supplies without this technology – only a few millivolts remain measurable. This makes phase alignment of the connected device superfluous.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSymmetrical, Low-Noise Power Supply\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe PWX power supply provides a low-noise, symmetrical DC voltage of approx. ±15 V DC for the Black Cube. The high current delivery capability ensures that even dynamic music signals are processed confidently and stably.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eProfessional Connection Technology\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe mains transformer is protected on the primary side. The mains supply is connected via an IEC socket. A power switch was deliberately omitted to avoid unnecessary contacts in the signal path.\u003cbr\u003eThe connection between the power supply and the audio section is made via a professional Neutrik XLR connector with gold-plated contacts, which is designed directly for the highest sound quality and long-term stability.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMechanically Quiet, Solidly Built\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe housing of the PWX is made of aluminum and, as with the Black Cube, is mechanically damped in the lid. This reduces unwanted resonances and further supports the electrical quietness of the power supply.\u003c\/p\u003e","brand":"Lehmannaudio","offers":[{"title":"Black","offer_id":54748503081301,"sku":"49040","price":399.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0995\/9715\/6693\/files\/IMG49040_69343.jpg?v=1787723631","url":"https:\/\/fidelity-hh.de\/en\/products\/pwx-netzteil","provider":"Fidelity","version":"1.0","type":"link"}
