We won't make the source code public.
But we can manage to support two versions I think.

Thanks Patrick. Looking forward to the next (last?) installment on the preamp. This unit should perfectly fit the needs of my system.

Have a great holiday!

Knowing how you love SMDs, I was almost certain we'd see MELFs on the attenuator!

Merry Christmas Patrick and Xen gang!

Bravo Patrick.............best project in a while.

How about a conceptual schematic (block diagram/flow chart). Definitely a must build.

Thanks and Merry Christmas...................

Regards,

Jam

Is it possible to run two preamp boards in your case, as I am using J Rivers MC18 as my sole source and crossover (as i cant find a suitable balanced crossover to place after the preamp) outputting two signals, Hf,LF, over USB into a exaU2I Multichannel Asynchronous USB to I2S Interface, into two dacs, into two? preamps, feeding two of your FX5's. Or can anyone suggest a better way of going active balanced ?

A friend is using F5XP & F5X for active crossover for his 2-way bookshelf.
He is going to use the F5XP to drive a purely passive filter network (LF & HF parallel).
These networks are followed by JFET follower, which then drives the F5XP.

I consider this a good solution indeed.

Thanks for the idea, LF & HF Parallel to obtain the balanced output? Any further details would be of great help.

No.

LF & HF in parallel so that you have one preamp driving two filters giving you 2 outputs.
That is per channel, so 4 outputs altogether for 2 channels 2-way active filter.

To use a passive filter followed by source followers, just treat them as single ended and duplicated 2x for balanced.
Suggest you start a new thread and also let other people help you.

Or you send me your X'ovr schematics by email and I'll have a look, when I have time ....
