[QUOTE="Ivan Beaver, post: 39318, member: 30"] Re: Loudspeaker to Line Level Pad Since both resistors are the effective load on the amp-you add them together for 600ohms (I am assuming that your measuring circuit has a high impedance-so the "load" will still be 30 ohms-or the total seen by the amp will be 600 ohms . Then figure the current from the applied voltage. Then you use the current to figure the voltage drop across each one (it will be proportional to the value of the resistor). [/QUOTE]
