Use 15V with the 150R resistors. The resistors are selected based on voltage, they don't determine the voltage. The regulators on board regulate the buffer to +-10V.
I plan to make an active 12dB xo for my three ways system , any inconvenient in using this buffer in the active stage ? Is R8 , 10k, acting as filter component in the HP ?

Hi
some question
what funktion have the 2 uhenry coil
No caps on in and output ?
0.25w resistor ok ?

The 2uH coil is a simple stability compensation.
The board has no DC blocking capacitors.
0.25W resistors are used for everything except on the on-board regulators where 0.5W resistors are needed at higher input voltages.

Why not? It has already gone I/V conversion so you can follow with whatever you want. But you would want different psu's.
Hi,
I believe I've read it somewhere, but I can't find it; can the Kuartlotron drive several outputs simultaneously, so I can use it to attach a subwoofer?
Thanks

I had some resistors bringing down my voltage just a hair (big resistors). I've got to say that I pulled them out because I was experiencing some problems with the volume I was trying to play at. Now that my voltage is a bit higher, I can play without that problem. It's my opinion that the voltage recommendations are too low unless you have 91db or better speakers.
I have a 2x12v transformer, and in retrospect I'd love to increase it - probably will at some point.
I'm using the older boards that had the error between some pico cap and resistor, without the regulators.

If you must increase the voltage, trim R5 so that TP is half of V+.
Done.
I'm at 12.71v and 6.35v now. If there is a sonic change, I'm not completely certain. Maybe slightly smoother and easier to read, but it took a minute to do with my double stack layout so it wasn't very back to back.
My caps are only 16v. I'd have to upgrade them to upgrade voltage. We'll see

Hello Kean
I would like to implement the kuartlotron in the output of my new paradise build that has +-18Vcc
Can I power the kuart with these voltages without major surgery ?
