Note that that the available gain and attenuation is combined for both the Master and Zone controls, for example if the Master
is boosted by 15dB you will not be able to boost any Zones. If the Master is boosted by say 5dB you will have up to 10dB of boost
available for the zones. If you attenuate the Master by say -30dB you will only have -10dB of attenuation for the zones and so
on.
At the bottom of the Master fader is a Mute button which will mute the entire array. The button and all zone mutes will turn red
when activated.
Next are the Zone faders which allow gain trim and mute for each of the zones that have been configured, in the example above
there are three. The maximum number is six. Gain may be adjusted exactly as described for the Master fader, dragging the fader
knob or typing a value. All zones may be adjusted completely independently. The zones also have a Mute button which will
instantly mute a zone. A further click will un-mute the zone.
All zone mute buttons will also turn red to show they are all muted;-
The Mute buttons can be freely changed whilst in normal mode, during set-up for example but when in Show Mode you will be
prompted to confirm a mute function to avoid accidentally muting something while a show is in progress. See the Show Mode
chapter for more details.
The zone metering is post PEQ, each zone can be equalised independently so the metering will show the effect this has had in
addition to the effect that any gain trim has contributed. The zone meters differ from the Master in that they display headroom
rather than absolute level. 0dB at the top of the scale indicates clipping the signal level reached will show how much headroom
is available before clip.
The entire array is shown as a thumbnail diagram with each cell shown on every enclosure, on the left is an MLA/MLD array, on
the right is MLA Compact, both have been zoned in the same way;-
