DIY balanced line converter with bassis

[NEO Dan]

It appears the Marchand has blown off my order for a Bassis board and parts kit, oh well

In light of that I'm here to ask for guidance on producing a couple different modules

1: A Sallen Key filter based LFE EQ unit with feature set of the Bassis with some extra features and adjust ability. I want selectable, adjustable, defeat-able 12/18 dB per octave HPF with adjustable Q. And balanced output that's robust enough to handle driving several amp inputs in the normal Pro amp daisy chained(parallel) configuration.

2: A high quality balanced line converter for use with AVR pre outs, I'd like to have some switch or jumper selectable gain options like unity, 3, &6 dB gain

Ideally I'd like to do the modules in such a way that you could pack enough of them into a 1 RU(preferably) enclosure to handle an 8.2 AVR setup. The idea that comes to mind is a vertical oriented PCB with a RCA in on one side and an PCB mount XLR out on the reverse.


TIA for taking the time to look this over

Fire away

Is this even the correct forum for preamp discussion?

If not, would a Moderator please move this into the correct spot

Thanks
