Signed number (2 complement)
This register is used to select the enhancement or attenuation STA015 has to perform on Treble Frequen-
cy range at the digital signal.
A decrement (increment) of a decimal unit corresponds to a step of attenuation (enhancement) of 1.5dB.
The allowed Attenuation/Enhancement range is [-18dB, +18dB].
