Simple buffer for balanced inputs?

Nisbeth · 21st October 2005, 08:01 PM

I need to buffer a balanced input with a low(ish) input impedance. I'd prefer something simple, i.e. similar to Nuuk's GC-buffer or Pedja's JFET-buffer but I can't seem to find any balanced circuits

Any tips/hints/links?

Bump! No suggestions?

Why not just take any buffer you like and use two of it for each channel?

Hi,
would any of Pass Zen be what you are after?
Borbely line/buffer?

Check these pages:

There are a lot of audio schematics (although I can't understand a word of what is written, but who cares?).

Andrew: I've been eyeing the Pass BoSOZ but I'd like something simpler if possible an dthe high supply voltage is a problem as well. I haven't totally written it off though

I had actually forgotten about Borbely, I'll look through his designs as well

Paolo: My Polish is really bad as well(

), but I'll try and see if I can make any sense of it. Thanks for the tip!

More suggestions appreciated

/U.

Is something like this what you seek? I still have two of these boards and each one is for a stereo amp.
