Levels

The amplifier section can deliver up to 0.5W RMS per channel and has a fixed gain of

20dB. The volume potentiometer varies the input level to the amplifier stage. Too

high an input level here will reduce the useful control over the output volume, since it

will have to be set very low to ensure that the output does not clip. To adjust this level

see below - 2 & 8 Inputs.

Note on the problems of Loudness and Headphones

Our amplifier cannot do the impossible! We can only make headphones as loud

as they are capable of being. Beyond that they distort and clip, which is very bad

for your ears, short and long term. The problem usually is not so much that the

headphones are not loud enough; it is more that the sounds outside are too loud

and are breaking through into your ears. Approached from this direction the

problem can perhaps be solved more easily.
