important to make sure that the amplitude of the signal remains within values that ensure that no
distortion is introduced in the signal at the output.
The 0 dB mark on the level meter has been adjusted to correspond to -20 dBFS (full scale). This
means that at that level, the signal is -20 dB below the maximum allowed value. This 0 dB level
mark should typically correspond to playing at mezzo forte (moderately loud) level. This ensures
a headroom of 20 dB which should be more than enough to cover the dynamics of most playing
situations and therefore guarantee that no additional distortion is added in the output signal.
The top LED of the VU-meter (red) is activated when the maximum allowed value of the signal
is reached. The signal is then clipped. Before this limit is reached (17 dB), a limiter is triggered
in order to ensure a smooth transition before clipping occurs. When the limiter is activated, the
yellow LED next to the
Volume knob is switched on .
