being kept at the nominal 0.01 μF. These values naturally
modify the bass tone response as in Figure 2 and Figure 3
With pins 7 (loudness) and 12 (volume) directly connected,
loudness control starts at typically 8 dB volume, with most
of the control action complete by 30 dB.
Figure 10 and Figure 11 show the effect of resistively offset-
ting the voltage applied to pin 7 towards the control refer-
ence voltage (pin 17). Because the control inputs are high
impedance, this is easily done and high value resistors may
be used for minimal additional loading. It is possible to re-
duce the rate of onset of control to extend the active range to
50 dB volume control and below.
The control on pin 7 may also be divided down towards
ground bringing the control action on earlier. This is illus-
trated in Figure 12 With a suitable level shifting network be-
tween pins 12 and 7, the onset of loudness control and its
rate of change may be readily modified.
