Hi I have a Beyma FD212 two way crossover rated at 1200hz. In the interest of bi amping and a somewhat unusual configuration, I'm curious if I can use this crossover in a 1 way configuration. The implementation and question is as follows: Can I send a full range signal out of a dac to an amp and in turn directly into the crossover's input, bypassing the woofer section of the speaker? And in turn send the output of the crossover to a 1.4" compression driver? Thanks for the help.
Yes, if it's the usual parallel type of crossover, no problem.
It also appears that you can remove a woofer section jumper to completely
disconnect the woofer crossover components from loading the amplifier.
I would do that.

Does that mean just putting a jumper between the +/- input terminals for the woofer input on the crossover which on the FD212 is the two middle screw terminals? Or jumper some other set of inputs and outputs? Thanks.
Don't do anything like that unless you get the right schematic, I don't have it.
The amplifier could be shorted out if done incorrectly. Maybe someone will post it here.

No! It will short the amplifier!
The safest thing to do is to de-solder one of the copper wire leads of the big inductor, and lift the copper wire away from the PCB.

rayma mentioned a jumper to do the same thing (removing a jumper, not adding one).
Currently some of us are in the dark and guessing on such features because you have not provided that information. Some configurations you need to do nothing, but some will cause problems if you do nothing. Some things can cause damage if you do something.

A related Beyma crossover has jumpers to connect one of two inductors.
No jumper would leave the woofer section disconnected.
Maybe this crossover is similar, but you'd have to post some photos of the board,
both top and bottom.

Yes, don't worry. De-solder the wire which is on the outer diameter of the bigger inductor and lift it up from the PCB.
You're welcome. I would have disconnected something easier instead of the inductor, either a particular wire or the capacitor. The effect would be the same, but I don't know if this is possible in this case.
Just to help make the point I've simmed the possible impedance issue from not connecting a woofer. It's probably not obvious that disconnecting something actually causes a lower impedance.
