Applications Information
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 con-
trol range and modifying C
lustrating this for the case of bass boost is shown in Figure
13. The resulting responses are given in Figure 14 showing
the continuing loudness control action possible with bass
boost previously 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

plications. As an example Figure 15 shows the responses
