BlackNoise 1000 V2

BlackNoise 1000 - db attenuation at different frequencies. 50/50 ohm standard input/output impedance.

The graph express db attenuation as function of frequency for the BlackNoise 1000. 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 1000 is very much alike the 500 regarding performance, with the advantage of providing about 1000 W of maximum absorption. Its use is slightly more specialized, being best suited for power amps or integrated amps rather than with sources or preamps. Another very good field of application for the 1000 (alike its bigger sibling, the 2500) is with electrostatic speakers or OTL amps.

 

On this subject see also the Comparison Table for adviced unit/gear matching.

 

 

 

 

 

 

 

 

 

 

 

As for the 500, the 2500 or the MiniBlack, the 1000 may be used as the only filter in a audio/video setup, eventually connecting to one of its outputs an energy distributor (see Four, Six, Eight - Derive!), but keep always in mind that the best results (more so if your setup needs so many Watts) are obtainable with multiple different filters specialized for each audio component.
