Preliminary specication
Sound fader control circuit
TEA6320
If the 20 dB gain is not required for the maximum volume
position, it will be an advantage to use the maximum boost
gain and then increased attenuation in the last section,
Volume II.
Therefore the loudness will be at the correct place and a
lower noise and offset voltage will be achieved.

a. Gain volume I = 20 dB (Gv(max)); gain volume II = 0 dB; fader and balance range = 55 dB.
b. Gain volume I = 20 dB (Gv(max)); gain volume II = 6 dB global setting; fader and balance range now 49 dB, previously 55 dB.
