microphones are used on the same source (e.g. snare top and snare bottom)

source is set to digital (USB/SD).
 Gain Assistant, Gain and Phantom Power are only available on Analogue Input

HPF
The High Pass Filter lets audio above a set frequency through whilst cutting out
lower frequencies. It’s commonly used wherever the low frequencies are
undesirable (e.g. microphone handling noise, traffic rumble or low background
humming) or when it is not adding anything to the mix (e.g. on predominantly mid or
high frequency sources like voice, guitar or cymbals).
Freq – Adjust the High Pass Filter frequency. When HPF is In, all frequencies above
this setting will pass whilst those below will be attenuated.
In/Out – Switch the HPF In or Out.
