INSTALLATION INSTRUCTIONS
Installation Instructions
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 poin-
ting to the center, resulting in a beam-shape coverage pattern over the entire length of the hall
or festival tent. Placing the 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 the coverage while at the same time the near filed 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 to-
wards 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 reali-
zed when employing 2 MID-HI cabinets per side. In these cases, exceptionally preferable is the
“stack and splay” technique - turning the two MID-HI cabinets which are placed on top of each
other. This results in smoother sound reproduction over the entire audience area.
In many halls and festival tents the bass response can be dramatically improved by placing the
woofer systems directly on the floor instead of setting them on the stage. In return this requires
that the MID-HI cabinets are installed on loudspeaker pole-stands.
Arraying woofer systems to a central “cluster” results in extreme bass SPL in the near field of the
“woofer cluster”. The SPL drops rapidly over the distance.
Compared to the woofer-cluster-configuration, placing the woofer systems de-centralized on the
floor along the edge of the stage results in a reduced low-frequency SPL in the audience area
next to the stage. But on the other hand, the bass response and punch stays constant over a
wider distance.
