LO MID Q
Adjust the Q of the LO MID Filter
Q is ‘magnification’ at resonance, and is inversely proportional to bandwidth. For an equaliser it is useful to think
of it simply as a bandwidth control (the width of the ‘bell’ in the case of a bell-shaped filter). That is, the higher
the Q, the lower the bandwidth - or the more ‘focussed’ the filter. Bandwidth (in octaves) is shown on the Touch
Screen with the Function Focus feature.
LF FREQ
Adjust the centre frequency of the LF shelving lter.
The filter will boost or cut the signal at this frequency by the amount set by LF Level. The cut-o frequency will be
higher, according to the filter slope.
LF Level
Adjust the boost/attenuation of the LF shelving lter.
EQ On/Off
Switch the EQ process for this channel On and Off.
Pressing and holding the key will activate Interrogate mode for this function (see Mix Features 8.3).
