Martin Audio W8L Longbow Application Manual page 130

3) Line Arrays are designed for long throw applications. Air absorption can cause
significant high frequency attenuation at low humidity. Line array columns are usually
band zoned (ie progressive shelving control is applied to the upper mid & high
frequency sections of line array columns to partially compensate for air absorption).
This band zoning relies on the exceptional mid and high frequency performance
provided by adequately powered high-efficient mid and high frequency sections.
Please note that our standard controller limiters are set with finite attack times. This
allows all them to pass transient signals to the full output capability of the MA2.8S
without compression but to pull back to a suitable continuous power for sustained
signals such as rail-to-rail feedback.

How do I patch my racks to take advantage of standard
W8LM controller presets?
