3. Loudness adjustment
When loudness is set, the boost amount can be varied by adjusting voltage at pin (11/13).
Under V (11/13) = 0 V, maximum boost amount is obtained and under V (11/13) = VREF (connected to pin
(10/12)), minimum boost amount is obtained (refer to the subsequently described GV V (11/13) data).
4. Relations between tone control and loudness
Because of the circuit configuration on this IC, the sum of boost amount by bass/treble control and boost
amount by loudness setting is restricted to become below a constant value. Therefore, the greater the boost
amount in-creases, the lower the boost amount by bass/treble control is reduced because loudness is
extensively applied. As opposed to this phenomenon, on the other hand, the cut amount increases. (Refer to
the subsequent descriptions on tone control frequency response during loudness.)
