JBL XPL-200 Input/Ouput Cards for JBL's DX-1 Crossover
 

I need helping in finding 2 sets of JBL XPL-200 Input/Ouput Cards made for
JBL's external active DX-1 Low level network crossover kit?

The cards must suit JBL's XPL-200 speakers.

The DX-1 crossover kit can take a varied number of cards and JBL made cards
to suit a particular range of speakers they sold.

JBL no longer makes these cards so any help finding where I can find these
cards or if anyone has any sets for sale, I'd be interested to hear from
you.

Cheers
