INSTALLATION Installing with the InvisiBall TM Mounting System - The InvisiBalfM is a unique method of mounting a loudspeaker. Patents are La methode de montage d'un haut- parleur avec InvisibalfM est unique en son genre. Les brevets sont en instance pour le monde entier a propos de ce produit.
Input - Simply connect the amplifier's "+" and "-" outputs directly to the red (+) and black (-) input jacks on the back of the enclosure (see diag. 1). - Since the loudspeakers have a rated ce of 8R each, more than one speaker usually be wired to one amplifier channel (see See "amplifier impedance load" below.
INPUT LEFT RIGHT AMPLIFIER 4Cl PER CHANNEL 6.n EACH CHANNEL -- SerieslParallel - It is possible to utilize various serieslparallel 'hook-up' topologies to increase the number of loudspea driven on an amplifier. See diag. 4 for one example of a serieslparallel hook-up topology.
because of differences in the acoustical setting. Since an enclosed room presents acoustical boundaries (walls, floors & ceilings), sound indoors exhibits quite complex behavior. Each time a sound wave strikes a boundary, part of the wave's energy is reflected and part is absorbed (see diag.
HORIZONTAL VERTICAL Boundary Loading - This is a good trick for increasing bass without taxing the amplifier. It is also possible to make a system sound too "muddy", so use caution. If you move the speaker from open space to a wall, bass notes will increase by + 3dB.
SOU Wind - Wind gives the illusion that a sound is coming from a different direction than it really is. This creates a re<ant propagation vector (see diag. 1). When sound propagates with the wind it tends to refract downward, and against the wind refract upwards (see diag.
It is important to understand that just as the propagation of sound outdoors is effected by its surroundings so is the propagation of sound indoors. Some of these environmental factors exist in both cases, such as reflective surfaces and absorbant materials, but there are a few unique effects that may need to be considered.
