BlackNoise 2500 V2

BlackNoise 2500 - db attenuation at different frequencies. 50/50 ohm standard input/output impedance.

The graph express db attenuation as function of frequency for the BlackNoise 2500. 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.

The 2500 is the filter with the highest maximum absorption throughout the BlackNoise range, almost equal to a standard Italian domestic energy contract. Hardly you will ever need anything more powerful!

 

The natural use of the 2500 is with high-power amps where, without absolutely showing  any kind of dynamic compression, is able to excert a very effective protection and elimination of mains noises and harmonics. Another very good field of application for the 2500 (alike its smaller sibling, the 1000) is with electrostatic speakers or OTL amps.

 

 

 

 

 

 

 

 

 

 

 

If needed, the 2500 may be used as the only filter in a audio/video setup (in the same manner as the 500 , the 1000 or the MiniBlack) but if your setup absorbs so many Watts that not even the 1000 is enough, it’s certain that connecting everything to a single filter it’s not the best course to take: separating sources from power amps is always a “healty” practice toward highest possible quality.
