Treble filter
The bypass filter cutoff frequency (fc1) can be altered
by changing the value of the external capacitor C
3
.
The recommended value for fc1 is about 8kHz.
The bandwidth of the internal amplifier is determined
by fc2 (about 100kHz).
The tone control provides gain boost or cut over a fre-
quency range that you decide. At the peak and bottom of
the frequency characteristic the boost is 15dB, and the
cut is
15dB (Typ.). Take the frequency characteristic
into consideration when designing the filter.
(
1) Amount of tone boost
When the amount of volume attenuation is large, the tone
control width will change. Reference values are given be-
low.
Note, however, that the actual values will vary due to dif-
ferences in individual components.
