Direct distributor
Product information "Direct distributor"
For connecting devices or active speakers with a cold appliance plug of protection class I to the 230V power grid.
A weakness of conventional power cabling systems is the use of Schuko plugs and sockets, which are not designed for shielding. Every Schuko socket is effectively a 44 mm diameter hole in the shielding, allowing high-frequency interference to enter. This issue is addressed with the Audio Optimum Direct Distributor, which directly and star-shaped connects up to eight shielded and ferrite-sheathed power cables. The connection is made via 24 Wago terminal blocks on two stacked circuit boards inside an RF-shielded aluminum die-cast housing.
Beneath the distributor housing is a second housing of the same size containing the Audio Optimum-developed Power Cleaner. It consists of four copper plates insulated and mounted in defined distances on top of each other, with surfaces coated in black tourmaline. The two outer plates are connected to the protective ground, while the two inner plates are connected to neutral and phase, acting as X- and Y-capacitors with a lossy dielectric. Combined with the ferrite-coated input cable, which acts as a lossy inductor, an efficient second-order network filter is created. The ferrite suppresses high-frequency magnetic interference through remagnetization losses, while the tourmaline suppresses high-frequency electric interference through re-electrification losses. Unlike conventional power filters, HF noise is not reflected but converted into heat, making the Power Cleaner ideal for use before the distributor.
The aluminum housings for the Direct Distributor and Power Cleaner, connected to the central grounding point, feature a stable tourmaline-polyurethane baked enamel coating on the surface, giving the overall construction the additional function of an effective ground box.
Each outgoing cable has a two-stage special power filter integrated, extending the filtering effect of the ferrite sheathing to lower interference frequencies. The continuous HF attenuation spans from 300 kHz into the GHz range. The output cables are routed upwards, keeping the compact Direct Distributor space-efficient.
In its combination of features, the Audio Optimum Direct Distributor is unique and guarantees the best possible sound quality for the connected system at any standard wall socket. The Direct Distributor is preassembled with three to eight output cables in the standard length of 1.6 m; for longer cable lengths, we offer custom quotes.
