Attenuator L-Pad switch to simple resistor problem

mudakas · 13th September 2005, 06:31 AM

Hi all,

I have decided to improve my old speaker quality by changing 40 dB 8 Ohm L-pad attenuator. Now the problem is what nominal resistor(s) and how to connect? Weird thing is that measuring resistance between 1-3 constant 0.2 Ohm, between 1-2 or 2-3 changes 0 to 3.4 and then to 0 Ohm again.

I am confused, any thoughts?

Thanks

Are you measuring the resistors? Are they IN the circuit, or have you pulled them out before measuring?

oops my mistake I disconected driver but not the l-pad, stupid multimeter

OK, the best sound for me at nom setting (0db) so one resistor 0 Ohms another as measured, (ripped off the l-pad already

Thanks
