The final output signal will be the same for both pre-out levels but in the high voltage pre-out, you don't have to increase the gain as much to get that desired output signal. Anything above the red lines would be driving the amp past it's maximum output levels and would be clipped.The amp is still doing the same amount of work but less noise is introduced into the system. A 5v pre-out is more than enough to keep noise low as long as your gain is set correctly.</blockquote>
