Power=
input Impedance=
Load impedance=

You may need to use a bridge/parallel topology depending on the above parameters.

Which model Beyma is it?

After having completed two gainclone projects, I am thinking of making the 200W bridged & parallel as found in the NSC datasheets. I want to know if anyone has ever done these schematics and if yes, how are the results?? I plan to make one to power a sub-woofer.

I'm currently building the 200W gainclone amp as shown in AN1192 for a subwoofer too.

I'll let you know how I get on. Should be ready in a week or 2

i read in a review for the original gaincard that it was a little lacking is the bass, maby bridging it to 200watts will help with this? what parts did you have to order from brian to build this?
