Bands 1 and 8 are Filters -- that means they do not boost, they only cut [remove, not move]. Specifically, a Filter cuts all frequencies beyond the Cutoff Frequency [the chosen frequency]. Band 1 is a low-cut [also called a High-Pass] Filter -- it cuts [removes] all frequencies below the Cutoff [chosen] frequency and passes all frequencies above the Cutoff [chosen] frequency; band 8 is a high-cut [also called a Low-Pass] filter -- it cuts [removes] all frequencies above the Cutoff [chosen] frequency and passes all frequencies below the Cutoff [chosen] frequency. A Filter more aggressively removes frequencies beyond the [chosen] Cutoff Frequency then a shelving EQ set to cut, though with some signals [and with some settings] the audible difference may be subtle. A typical example of when to use a filter would be to employ a low-cut [high-pass] filter to remove unwanted low-frequency thumps [footsteps] or rumble from a vocal recording.
