Fix vs low/high pass filter

[Cleet Torres]

Apologies if this is a bit (or a lot) of stupidity on my side.

Can a Fix be tweaked to act as a high pass filter? I am looking for a high pass filter, and given my other Bottlehead gear, The Fix would be a nice match on my rack.

Thanks guys.

Cleet.

I built a simple passive first-order crossover back in the VALVE days - six switchable frequencies, level adjustments on high and low outputs. I have a .pdf lying around - PM me with your email address and I'll send a copy.

Paul,
Would you still be agreeable to sharing this?  I'm getting Orca mini's for tweeters for my horns and want to modify a Fix (since I have one) to house a switchable filter.

Sure, it's pretty simple and straightforward. Doc B has the original, maybe he'll post a picture!

PM me an email address and I'll send it.

Haha - thanks, Dan. Takes me back. The old thing is pretty grody after all these years, and most of the switch labels are worn off now - they were written with a sharpie originally. I think the switches and pots all came from Radio Shack. We did a lot of interesting experiments with it though.

It was on the bottom shelf of the rack of forgotten projects. I worked really hard not to disturb the scum, I mean, vintage patina.
