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 field 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 floor 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-configuration, de-centralized placing the woofer systems on the floor 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 floor along the edge of the stage on the other hand provides considerably improved low-frequency response over wider distances.
