• Fader 1 - "100Hz": 100 Hertz.
• Fader 2 - "200Hz": 200 Hertz.
• Fader 3 - "400Hz": 400 Hertz.
• Fader 4 - "800Hz": 800 Hertz. This is just below where audio engineers and audiophiles describe "midrange" frequencies existing.
• Fader 5 - "1.6KHz": 1,600 Hertz.
• Fader 6 - "3.2KHz": 3,200 Hertz - upper midrange to treble frequency.
• Footswitch 1 - "On/Off": This switch toggles between active or engaged ("On") and bypassed ("Off").

Note that in the middle of the pedal MXR has labelled the enclosure with a painted indicator showing +18 dB to -18dB in the span of the faders.

Setting the fader for a particular frequency at "0" (zero) means that that frequency is being neither boosted nor attenuated. An M109 with all faders at "0" should have the same volume level and therefore sound the same when "on" as "off. This is called "Unity Gain". Moving the fader of a selected frequency up increases the volume of that frequency in the output signal; likewise, sliding that same fader below "0" reduces the volume of that same frequency.

Note that while the M108 10-Band EQ offers separate Volume and Gain faders on each side of that pedal, the M109 6-Band does not. However, MXR tries to make up for it by offering +. If many or most of the frequency faders are at zero or below, the total signal level coming out of the pedal may be below the original unity volume level.
