User manual BOSTON ACOUSTICS VSI 580

[. . . ] The aluminum cup is specially sculpted to eliminate diffraction when the tweeter is pivoted. All VSi models include a boundary compensation switch that allows the installer to shape the sound of each speaker to counteract the effect of being installed too close to a listening area's corner, or too far away for that matter. The VSi speakers have aluminum grilles and are constructed of rugged materials--making them ideal for installations in kitchens or bathrooms. Since the speaker installation is permanent and the furniture placement may not be, you should first determine the best long-term location for the speakers--one that will accommodate future relocation of the furniture in the room, while still providing wellbalanced sound to the primary listening area. [. . . ] The NCB brackets act as a perfect guide when cutting the wallboard. If you need to remove the grille, gently lift it out at the edges. The response of a speaker changes when it is mounted close to the boundary junctions of a room (near an adjacent wall or close to the corners of the room). Your Boston VSi loudspeakers have been carefully voiced to compensate for these boundary effects. The speaker is mounted less than 18-inches (46cm) from the junction of two surfaces (wall/ceiling). The speaker is mounted less than 24-inches (61cm) from the junction of three surfaces (a room corner). Less than 24"/61cm ­ Boundary Compensation ON More than 24"/61cm ­ Boundary Compensation OFF Less than 18"/46cm ­ Boundary Compensation ON More than 18"/46cm ­ Boundary Compensation OFF Always turn off the amplifier or receiver when connecting speakers or any other components to the system. This manual assumes the installer possesses skill in the proper use of hand and power tools, knowledge of local building and fire codes, and a familiarity with the environment behind the wall or ceiling in which the speakers will be installed. A utility knife, jig saw, or other tool for cutting the required hole in the mounting surface. Make a small hole at the center of the speaker location. Insert a long, bent piece of wire and rotate to confirm that there are no obstructions behind the chosen location. Run the wire from the amplifier location to the cutout. Allow for an extra foot of wire at the cutout. The VSi speaker jack will accept either bare wire up to 12-gauge, or single banana plugs. The mounting arms will pivot into position and clamp the speaker to the mounting surface. If you wish to paint your speakers or grilles, it should be done prior to installation of the grille. Insert the grille into the slots in the baffle by gently applying pressure along the edge. The speakers may be painted before or after they are installed. Insert the supplied paint mask into the frame of the speaker. If you are using spray paint, apply two light coats. If you are applying paint with a brush or roller, thin the paint and apply two very light coats. This helps prevent excessive paint buildup or "runs" on the frame. [. . . ] This warranty does not cover the cost of removal or reinstallation. This warranty is void if the serial number has been removed or defaced. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. First, contact the dealer from whom you purchased the speakers. [. . . ]
