User manual ALTO ATTIX 360-2M SPARE PARTS

[. . . ] Partial magnetic shielding allows use of the speaker as close as 230 mm (9") to video monitors. The top-quality line distribution transformer, designed for minimal insertion loss and reduced saturation, allows use of either 70V or 100V distributed speaker lines. In bypass position, the high 8 impedance allows use of multiple speakers on a loudspeaker line. [. . . ] The included InvisiBall mounting method is simple to install, aims easily and provides a high degree of theft deterrence. InvisiBall allows horizontal rotation of up to 41° off-axis and vertical rotation of up to 36° (horn end inward) or 23° (woofer end inward). Attachment points for the optional MTC-29UB U-bracket allows for compact installation and is particularly useful for low profile underbalcony applications. The woofer's cone is made of kevlar, surround is pure butyl rubber, and the driver basket is rear loaded to minimize direct exposure. The grille is thermoset composite coated and comes with foam to minimize incursion of water. Nickel/zinc rust-resistant terminals ensure a secure input connection. An MTC-PC2 sealed-entrance cover is included to further protect the speaker's terminals. ALTO's exclusive SonicGuard overload protection is virtually inaudible to the listener, ensuring reliability while providing full fidelity sound. Available in black or white (-WH). The cabinet will accept a variety of paints to match any décor.

The system shall be protected against damage from occasional overpowering via full range limiting, which shall be inaudible during activation. The compression driver shall be horn-loaded to cover 110 degrees by 85 degrees with a high degree of accuracy and the horn shall be rotatable to achieve these coverages either in the horizontal or vertical planes, regardless of cabinet orientation. The grille shall be secured via screws to keep it in place when facing downward. The low frequency transducer shall have woven kevlar cone and butyl rubber surround, with the frame protected from direct weather exposure. The compression driver shall be constructed with a titanium diaphragm for weather resistance. The system shall withstand Mil Spec 810 testing with specified durations with no effect on its acoustical performance or structural integrity: salt spray (method 509. 3), temperature (method 501. 3 and 502. 3), humidity (method 507. 3) and ultraviolet (method 505. 3). For theft-deterrence, the installation access area shall be hidden behind a snap-out cover on the front grille. The cabinet shall have ten (10) 6 mm mounting points, including 2 on each side and 3 on top and bottom and an accessory U-bracket shall be available. The grille logo shall be rotatable for proper orientation with loudspeaker mounted horizontally or vertically. [. . . ] The grille logo shall be rotatable for proper orientation with loudspeaker mounted horizontally or vertically. Overall cabinet dimensions shall be no greater than 520 mm high x 306 mm wide x 277 mm deep (20. 5 x 12. 0 x 10. 9 in) and shall weigh no more than 12. 2 kg (26. 8 lb). The system shall be the ALTO Model Control 29AV (or Control 29AVWH) with included InvisiBall® (mounting system). Control® 29AV High Output Indoor/Outdoor Monitor Speaker Vertical 1/3 Octave Polars High-Pass Frequency Recommendations The transformer in Control 29AV has been designed to minimize transformer saturation, however it is recommended that when driving the transformer settings with very high signal levels, that the system be highpassed to prevent excessive low frequency content from overloading the transformer and stressing the driving amplifier.
