Vidsonix Virtual Crossover Box
Sample Champion

 

Vidsonix Virtual Crossover Box with Sample Champion


We are testing the Vidsonix Virtual Crossover Box.





Key features of this product:

  • Design, test, and modify crossovers in realtime while listening (invaluable for A/B testing) or comparing software curves. Eliminate countless hours of design and mock-up building time.
  • A great tool for industry, hobbyists, or home / car installation specialists looking to “tune” their systems.
  • Allows for any type of external components to be used via quick-connect push terminals, or select from over 85 internal components using robust, long-life rotary switches.
  • Procuring all the required parts and assembling a similar circuit by hand would cost far more in time and money than the cost of this unit

Here are some measurements performed on the Virtual Crossover Box. We have used a loudspeaker filtered by the Virtual Crossover and performed the measures by means of a Microphone.

The scheme of the variable filters implemented in the Box is the following:

 

TW - HIGH PASS FILTER

Also the use of custom components is possible:

 

We have performed also some loopback measurements (connecting directly the sound card output to the input of the crossover and the output of the crossover to the sound card input). Some results are the following:

A large set of possibilities are allowed!

The connection scheme for a 3 ways Loudspeaker is the following:
