The channel EQ (Equaliser) section is used

for sculpting the tonal (frequency-based)

balance of the signal. The Performer EQ

has four fully parametric, full range bands

- LF and HF have switchable bell/shelf

The filter will boost or cut the signal at this frequency by the amount set by HF Level. The cut-o frequency will

be lower, according to the filter slope.

HF Q

Adjust the Q of the HF lter and switch bell/shelf mode.

The HF band is normally bell-shaped. When Q is turn to maximum, shelf mode is enabled and the shelving LED

will light. 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.
