ABSTRACT:
Electronic crossover modules and systems in accordance with the invention employ a set of crossover channels in each module together with internal input interconnections which enable input signals to be serially intercoupled but cutoff points to be separately adjustable. Each module comprises two independently settable, variably interconnectable high pass channels and a third low pass channel which also is independently settable, and which can receive signals from the first two channels and/or a different module and also transmit signals to a different module. Using the available input interconnections and a frequency multiplier control in the first channel, great versatility in bi-amp and tri-amp with two channel and/or four channel operation is achieved.
