Every amplifier of the 460/460B ROSSO family is equipped with a standard RS232 serial interface. You can read and/or modify all the main crossover parameters by just linking a standard PC and running the crossover configuration program (XOV).
The XOV program is a free software running under WIN98/XP/2K developed by Firenze Audio. It makes the configuration process a very simple job. You can change a crossover parameter on the fly and listen to the sound result in real time; once you have found your optimal configuration, save it into the non-volatile memory and disconnect the PC.
The most updated release of XOV.exe (1.0) can be downloaded at the following link:
(The program doesn't require any setup procedure and can be easily launched from a pen drive or any other removable media)
