Paralleling is required if you also bridge connect _or_ have load under 4 ohms.

Check these files:

To answer your question: Thomas Madsen's "Das Modul" is a developed version of BPA200 taken from AN-1192

Default parallel chips

Hi Palesha

Have a look at my replay in:

Can you tell me how to beef up PA100?

It is all about parallering

Have fun

Thomas

If you look at one of Jeff Rowland's amps (the photo is on another HD), he implements a multi-turn pot. It probably zeroes the DC offset on each chip, as he parallels 3 LM3886s on each bridging side.

The Concentra, on the other side, doesn't seem to have individual adjustment and apparently uses inverting LM3886 arrangements.
