CQ-18T

Invert Polarity – Invert the polarity of the signal. Often used where multiple microphones are used on the same source (e.g. snare top and snare bottom) Gain – Adjust the gain manually for the incoming signal. Trim – Digital level adjustment, available on stereo line inputs and when an input source is set to digital (USB/SD).  Gain Assistant, Gain and Phantom Power are only available on Analogue Input Sources. Level – Displays the post-preamp (pre-processing) input level. 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.
