De Referenz AC-3502 Power Station onderdrukt betrouwbaar ongewenste interferentie uit het elektriciteitsnet. In het hart van de stroomverdeler bevindt zich een zeer efficiënt parallel filter, nauwkeurig afgestemd op audiophile eisen, dat storende interferentie zowel vanuit het lichtnet als van de aangesloten apparaten zelf effectief afvoert zonder de energievoorziening te beperken. De stervormige verdeling zorgt ook voor een homogene toevoer naar alle aangesloten componenten. De Referenz AC-3502 Power Station is een centrale pijler in het bereiken van een geluid dat zowel verfijnd als krachtig is. De technologie zit in een solide metalen behuizing met een geborstelde zwart geanodiseerde aluminium voorkant. Aan de achterkant zijn zes hoogwaardige stopcontacten beschikbaar. Dankzij de centrale hoogstroomnetstekker (IEC C20) kan de voedingskabel indien nodig eenvoudig worden vervangen, bijvoorbeeld door een langere kabel. Geïntegreerde overspanningsbeveiliging beschermt de aangesloten apparaten tegen dagelijkse spanningspieken, en de stopcontacten kunnen gemakkelijk worden in- en uitgeschakeld met de "Power" knop op het voorpaneel.
Background
Where does fine sound begin? Where does it end? Audiophile is asked this question constantly. The truth is, physical factors have a major impact on the sound quality produced by audio systems. This also includes the power supply: In principle, we hear nothing other than household current modulated by the music signal. If this useful signal mixes with modulation or interference from other consumers in your own home and sometimes even from the neighborhood, the sound starts to deteriorate: Countless consumers, especially digital consumers, switching power supplies, car charging stations and PV systems, generate strong distortions in the power grid – and the trend is rising. These distortions make life difficult for the hi-fi components and cover the sound like clouds of acoustic fog. Now, very few hi-fi enthusiasts operate their own power station, so they are inevitably connected to the heavily loaded power grid. For most people, the sound starts at the socket or even at the fuse box – everything before that is beyond our control.
Parallel filter
It is therefore necessary to filter the interference from the power supply – conventional filters, however, are known as “dynamic eaters”, which is certainly also the case with serial circuits. The reason for this are coils connected in the supply line, which definitely increase the transition resistances and slow down dynamic impulse currents. At the core of the Referenz AC-3502, however, is a highly efficient parallel filter, finely tuned to audiophile requirements, which effectively dissipates annoying interference both from the mains power and from the connected devices themselves without restricting the energy supply. This is supported by the damped sub-chassis, which dampens the mechanical vibrations of the filter components caused by the 50 Hz mains frequency. The star-shaped distribution also ensures a homogeneous supply to all connected components. The Referenz AC-3502 Power Station is a central pillar in achieving a sound that is both refined and powerful.
Further features
The technology sits in a solid metal housing with a brushed aluminum front. Six high-quality sockets are available at the rear. Thanks to the central high-current mains connection socket (IEC C20), the power cable can be easily replaced if necessary, with a longer cable for example. Integrated surge protection safeguards the connected devices from everyday voltage peaks, and the sockets can be conveniently switched on and off using the "Power" button on the front panel. The operating state is indicated by LED lighting: If the LED lights up red, the sockets are switched off. If the LED lights up blue, the sockets are switched on.
