What do you gain from that "setup"? As a buffer or what? Doesn't make any sence of it being used as a buffer though, because the opamps are the same.

In the A47, you'll notice that the opamps aren't in series, they're actually in parallel. The output from the first half is driven in the input of the second half (this is how the gain is set), and then the two opamps are paralleled at the output. The resistors are there to stop large currents flowing between the opamps due to slight intrinsic differences.

In series, no benefit. In parallel, more current

Ah. Genius!

Thanks alot.
