A Note about EASE Focus 3’s broadband gain adjustments
Significant broadband gain boosts to the upper section of an array during manual adjustments
(using the Gain adjustments available in EASE Focus 3’s Systems properties panel) would cause
EASE Focus 3 to display significantly lower maximum SPL levels than the instantaneous peak
levels expected in practice. This is due to EASE Focus 3’s strict adherence to maximum RMS
SPL which doesn’t allow one array section (or “group”) to be boosted beyond its maximum SPL
capability. Instead, a “boost” to one group is translated as no boost at all, but simply as an equal
and opposite cut to all other groups in the array.
For instance, a 3 dB gain “boost” to the upper four cabinets of the 16-cabinet array above,
would simply attenuate the other twelve cabinets by 3 dB in EASE Focus 3 terms. This situation
would only happen in practice if all the array section limiters were ganged – and then only
when the highest gain section was driven into limit.
So, it’s best to leave any array shaping to the Void Arcline 8 presets – which will be banded
rather than broadband.
The array sizes per venue depth shown here will be perfectly sufficient in reality as peak SPLs
will be significantly higher than the RMS values shown.
7.4.4 Balconies and bleachers
As you will observe when designing systems for smooth audience coverage using EASE
Focus 3, array shapes need to be tailored to the venue profile (the shape of the audience
areas observed as a vertical section). The classic array shape (with increasing curvature from
top to bottom) often needs to be modified for venues with bleachers or balconies. In fact, the
upper (balcony) and lower (stalls) sections each need their own curvature – a kind of double-
curvature array.
Balconies example
This double-curvature approach is particularly important if the mix position is tucked away
under the balcony.
