Hi,
The active low x-over input of Infinity's RS-1B system has an impedance matching circuit, with a few switch settings to match the electronic crossover unit to the input impedance of the mid-high power amp. The system consists of two mid-high screens and two woofer columns which have the electronic servo x-over. The mid-high screens have a passive x-over.
The input circuit is shown on the x-over image. Mind you, this is a twenty-two year old system.
Is the impedance matching still necessary, because I don't see it being used in todays active x-overs. If necessary, can it be simplified in terms of components or replaced by another more suitable circuit?
Thanks for any advice.
