The higher gain is 5X which would equate to 10V at maximum volume with this source. However the amp can only output 7V. What happens here? Once the volume pot setting reaches 7V does it simply not get any louder or does it start to distort if you turn the volume pot any higher?
I’ve seen some mention of input overload. If I use a gain of 5X which is impossible to achieve will I always get distortion no matter what the volume because I’m trying to overload the input stage of the amp?
I’m pretty confused by this. I can’t really see why it doesn’t just have a fixed gain of 3.5X as 2V * 3.5 = 7V.
The reason why this has now become an issue is I’m thinking of buying another set of headphones which might need over the 5V available at the low gain setting to get loud enough.
The maximum source voltage is determined by the input transistors and not the output stage.
