GENERAL INSTALLATION NOTES
• When installing a sound reinforcement system for halls or festival tents over
their entire length, the loudspeaker systems have to be set up on the left
and right sides of the stage, slightly pointing to the center, resulting in a beam-
shape coverage pattern over the length of the hall or festival tent. Placing
Mid/Hi cabinets on both sides on top of each other (“STACKING”) provides
improved long-throw coverage. Stacking the loudspeaker systems in this way
almost doubles coverage while at the same time near eld reproduction is not
too loud.
• When installing a sound reinforcement system for halls or festival tents on
the wider wall side, the loudspeaker systems have to be set up on the left
and right sides of the stage, aimed towards the audience. Because of the
wider horizontal dispersion angle needed (“covering the front and the sides”),
this kind of sound reinforcement application can only be satisfactory realized
when employing two Mid/Hi cabinets per side. Exceptionally preferable for
these applications is the “stack and splay” technique - turning the two MID-HI
cabinets, which are placed on top of each other – which results in smoother
sound reproduction over the entire audience area.
• In many halls and festival tents low-frequency response can be dramatically
improved by placing the woofer systems directly on the oor instead of on
the stage. In return this requires installing the Mid/Hi cabinets on loudspeaker
pole-stands.
• Arraying woofer systems in a center “cluster” results in extreme low-
frequency SPL in the proximity of the “woofer cluster” with SPL dropping
rapidly over distance.
• Compared to woofer-cluster-conguration, de-centralized placing the woofer
systems on the oor along the edge of the stage results in reduced low-
frequency SPL in the audience area next to the stage. De-centralized placing
on the oor along the edge of the stage on the other hand provides
considerably improved low-frequency response over wider distances.
