Higher resolution of Loudness Gain is possible: An LSB step results in a gain
step of about 1/4 dB.
Loudness increases the volume of low and high frequency signals, while keep-
ing the amplitude of the reference frequency constant. The intended loudness
has to be set according to the actual volume setting. Because loudness intro-
duces gain, it is not recommended to set loudness to a value that, in conjunction
with volume, would result in an overall positive gain.
The corner frequency for bass amplification can be set to two different values. In
Super Bass mode, the corner frequency is shifted up. The point of constant vol-
ume is shifted from 1 kHz to 2 kHz.
