Hi Shannon,

Can you advice what is the input sensitivity of your driver board?

Thanks!

Referencing back to my manual, I see it took 1.06Vrms for 35W output and 1.165Vrms for 42W (1%THD) - so basically 1Vrms.

Thanks Shannon! :-)

Is it ok to put 100K pot on the input? or better to have an active stage?

Depending on your source, yes, you can just use a 100K volume pot. CD players will drive it easily. And devices like iPods are usually 1Vrms max output so you should be fine, though your volume pot will be cranked as well as the iPod volume control - but that isn't a problem.

Thanks for your inputs!
