Figure 3: Low Cut Filter Example Responses
6. See-Saw Filter
The See-Saw Filter provides simultaneous cut of one frequency band while boosting
another band. When the adjustment knob is turned fully clockwise, high frequencies are
boosted and low frequencies are cut. When the adjustment knob is turned fully count-
clockwise, low frequencies are boosted and high frequencies are cut. The filter has
approximately linear slope over the entire audio band. Max boost and cut are more
than 16dB, so significant shaping of the audio spectrum can be achieved.
The See-
Saw filter has a “pivot” frequency that is selectable as 400 Hz or 1 kHz by
pressing the front panel button. Therefore, frequency band emphasis can be changed
to match the source being equalized. The See-Saw filter has the same linear slope for
each setting. The plots below show a range of filter responses.
