Frequency Filters
The M.207 has 3 frequency filters at the top of the effect area. (Figure 4.16)

4.3.6.1 Filters as Effects
When you press one of the Frequency Filters, you will only hear the corresponding frequency range. Therefore, if you press the
MID filter, the audio will change and you’ll hear only the Mid range frequencies – kind of like an old telephone sound. Likewise, the
LOW and HI buttons will change the audio so that only the low or high frequencies are present. Like the other effects on the M.207,
these filters are adjustable via the PARAM and WET/DRY buttons. Unlike the other effects, to access the PARAM and WET/DRY
functions on the Frequency Filters, you need to be holding down the corresponding filter button before pressing the modifier
buttons.
These filters behave in much the same way that the M.Filter effects do. HI is a High-Pass Filter and PARAM controls the roll off
point. MID is a notch filter and PARAM controls the notch frequency. LOW is a Low-Pass Filter, where PARAM controls the roll off.
Therefore, if we wanted to adjust the Mid filter’s frequency, we would press and hold the MID button, then press the PARAM button.
You will see the MID button blinking to indicate that it is being edited. Moving your finger along the FXGlide™ Slider Strip will give
you a frequency from 20 kHz down to .05 Hz.
The WET/DRY parameter works in the same way. To adjust it, press and hold the frequency button (either HI, MID, or LOW) and
press the WET/DRY button. The FXGlide™ Slider Strip will allow you to dial in a setting from 0-100%. Just like editing PARAM, the
corresponding frequency button will flash when the WET/DRY parameter is being edited.
They can act as effects themselves, offering “reverse EQ kill” functionality,
or they can be used to limit the frequency ranges being sent to an effect.
Let’s go over each case separately.
