BlackNoise Extreme V2

Extreme. As the name says, the best filtering effect, the maximum protection and the uttermost possibile effectivness. With a mains harmonics reduction of -3db starting from 1800Hz up to an exceptional -170db from 1MHz upwards, the Extreme expresses the highest results inside the BlackNoise range.

The Extreme is designed to give the best of itself in conjunction with electronics that manage low-level signals as CDP, DVD, SACD, phono-preamps, step-ups and in general when is extremely important to preserve to the highest degree the original quality of the source signal. For this very reason, hardly the Extreme is the only BlackNoise installed: it gets the best advantage being employed together with any other BlackNoise, 500, 1000, 2500 or MiniBlack including other Extremes as well.

Two or more filters applied in the same audio setup not only have an optimal synergic effect in respect to the overall sound quality, but also reach the extremely important goal to completely isolate, from the mains network point of view, low-level signal units from high-level ones (i.e. power amps).

These ones have much higher power demands than sources and are prone to be very noisy from an electrical point of view: they inject notable disturbances concentrated over lower frequency bands. Digital gears, on the other hand, are prone to radiate the most of their disturbances over much higher frequencies.

Separating (at the mains level) power stages from sources and, to the maximum effect, isolating preamps too from the rest of the setup, lets each single electronic work to the top of its potentials avoiding any reciprocal interaction: this is an indispensable condition to get the best possible quality of the gear at our disposal.

In exchange for, the Extreme is limited to a maximum absorption of 230 W so it can’t be employed (nor has been devised to) with integrated or power amps. The only exception may be represented by very small (1-5 W) valve triode amps where the positive characteristics of the Extreme can be expressed without any contraindications.

BlackNoise Extreme - db attenuation at different frequencies. 50/50 ohm standard input/output impedance.

The graph express db attenuation as function of frequency for the BlackNoise Extreme. The yellow line represents differential mode filtering, while the blue line relates to the common mode one.

This graph is of comparative use: that is, it can be compared with any other filter on the market since it has been made with the standard 50/50 ohm input/output impedance, a common test value for this kind of equipment.
