GRAPHIC EQUALIZER CONTROLS
The advantage of the GRAPHIC EQUALIZER over conven-
tional tone controis is that with the five controls of the
GRAPHIC EQUALIZER it is possible to control five different
narrow, distinct sections of the audio band. With conventional
tone controis a setting for a bass or treble boost or cut will also
affect the lower or upper mid frequencies. The frequency
bands controlled by the five slide controls have been chosen
to yield the maximum possible control action within the audio
spectrum.
100 Hz: The 100 Hz control is very useful in enhancing low
bass notes as in organ music.
330 Hz; The 330 Hz controi will allow you to vary the upper
bass frequencies.
1kHz: The 1 kHz control is the presence control and can
be used very effectively to emphasize, or de-
emphasize vocalists.
3.3 KHz: The 3.3 kHz control will add brilliance and clarity to
brass instruments and violins.
10 kHz: The 10 kHz control can be used to make up for
missing high frequencies absorbed by the environ-
ment and to add a natural crispness to music.
