When adjusted for maximum boost in the usual application
circuit, the LM1036 cannot give additional boost from the
loudness control with reducing gain. If it is required, some
additional boost can be obtained by restricting the tone control
range and modifying C
ing this for the case of bass boost is shown in Figure 13. The
resulting responses are given in Figure 14 showing the con-
tinuing loudness control action possible with bass boost pre-
viously applied.
USE OF THE LM1036 ABOVE AUDIO FREQUENCIES
The LM1036 has a basic response typically 1 dB down at 250
kHz (tone controls flat) and therefore by scaling C
is possible to arrange for operation over a wide frequency
range for possible use in wide band equalization applications.
As an example Figure 15 shows the responses obtained cen-
tered on 10 kHz with C
