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:
