That's amazing, I was looking for an answer to this question this morning. I think I get it but do not quite understand everything. If I have a cartridge with .23mV output and I use a stepup transformer with 20dB of gain, then it will have an output of 2.3mV. If it has 40dB of gain then it would have 23mV, and if it had 60dB then it would output 230mV. I have an old Fisher 400 tube receiver with a phono stage that needs 4.5mV on its input (I don't know if this is minimum or what). If I had a stepup with 40dB of gain, wouldn't this overload the input of the receivers phono stage? Or do phono stages (as well as other inputs) accept a wide range of input voltages? If I used a stepup with 20db of gain (2.3mV) with this phono stage (which needs 4.5mV) then will I only get half the volume out of the phono stage or would it just have a lot more hiss?
Cartridge output matching to phono stage.
Greetings everyone! Here is a question that has been bugging me for some time. How does one know if the phonograph cartridge output, stated in "Mv", is properly matched to the phono stage being utilized, stated in "gain"? Some where a chart should exist allowing people to properly match their desired cartridge selection to their phono stage. Also, why is this so important, and what are the ramafications if you go above or below the gain threshold?
Thanks is advance for the feed back.
