Application Circuit
Applications Information
OBTAINING MODIFIED RESPONSE CURVES
The LM1036 is a dual DC controlled bass, treble, balance
and volume integrated circuit ideal for stereo audio systems.
In the various applications where the LM1036 can be used,
there may be requirements for responses different to those
of the standard application circuit given in the data sheet.
This application section details some of the simple variations
possible on the standard responses, to assist the choice of
optimum characteristics for particular applications.
TONE CONTROLS
Summarizing the relationship given in the data sheet, basi-
cally for an increase in the treble control range C
must be in-
creased, and for increased bass range C
b
must be reduced.
Figure 1 shows the typical tone response obtained in the
standard application circuit. (C
=0.01 μF, C
=0.39 μF). Re-
sponse curves are given for various amounts of boost and
cut.
Figure 2 and Figure 3 show the effect of changing the re-
sponse defining capacitors C
and C
to 2Ct, C
/2 and 4C
t
,
C
/4 respectively, giving increased tone control ranges. The
values of the bypass capacitors may become significant and
affect the lower frequencies in the bass response curves.
