Could anyone explain to me how to calculate (or indeed know) the input sensitivity of the First Watt SIT-1 amps?
per P=U^2/R , 10W/8R means U=8V94 rms at output
as 18db of gain means 7.94V/V (per db=20log(V/V) )
so ...... 8V94/(7V94V/V) ........ you need 1V12 at input , for full blast at output
as 18db of gain means 7.94V/V (per db=20log(V/V) )
so ...... 8V94/(7V94V/V) ........ you need 1V12 at input , for full blast at output
Thank you Zen Mod for the speedy explanation, it is great to know how to work these things out. As it stands my TP Buffallo DAC/Legato outputs exactly 1.5v.
That, as they say in Mary Poppins, is Fortuitous 🙂

Yes I'm hoping for supercalifragilisticexpialidocious Zen Mod, they hopefully arrive the middle of next week so we shall see. Current amps are Welborne Terraplane Monoblock 300B's & speakers are Beauhorn.. horns... 'Chim Chimney'
