Impedance matching volume control schematic. On a transistor amp its fine feeding a higher impedance in fact its better. You simply wire the pot as a potentiometer feeding the speaker something like a 50 ohm pot for an 8 ohm speaker a big wirewound one. A source of electric power such as a generator amplifier or radio transmitter has a source impedance which is equivalent to an electrical resistance in. And if you want a combinated impedance matching.
No impedance matching required only valve amps required impedance matching. The product shown to the right is what you need. If your microphone is low impedance and you play through a pa the best solution is my low impedance xlr volume control. Adjustable impedance jumpers allow as many as eight pairs of 8 ohm speakers to be driven by a single 8 ohm capable amplifier.
Two of the simplest involve the transformer and the. Ive seen the wiring schematics for connecting 4 speakers to a zp without any volume controls and ive seen the links for various impedance matching volume controls imvcs but i cant seem to find a detailed explanation of how one would actually connect 2 3 different imvcs from beginning to end. Impedance matching volume controls allows multiple pairs of speakers to be used with an amplifier. If you use your low impedance mic with a harpguitar amp then you also need to use an impedance matching transformer.
