I did some modification work on my crossover today so I thought I'd post a pix. This is a pretty stock-circuit 4th order LR 4 way crossover, nothing unusual except for the selectable subwoofer crossover frequencies and the transformer input coupling, in addition to loops for external EQs for the LF and HF and the usual channel switching. The signal capacitors are NOS polystryene except for the subwoofer channel which uses Wima. I designed it to work specifically with the requirements of my system. I laid out the PCB, chassis etc - 'Recording Technology' is the name of a company I had a long time ago to make mixing consoles - Neve never got worried about competition from me
. The XLR in the lower left hand corner is for the external PSU, and you can see the rail regulators on the left. The outputs are on the DB-25 connector on the back of the chassis. Hopefully the workmanship is a bit better than a certain 'truthful preamp'....
