Anleitung Zusammenfassung
reinforcement applications. Because of its compact size, unique 8-sided configuration and performance features, the 1230C solves professional-sized problems. Mounted inside the enclosure is Altec's 12-inch 617-8A duplex loudspeaker, well-recognized for uniform frequency response and high efficiency, with low and high frequency elements mounted coaxially to produce an extremely compact yet dynamic system. The high-frequency horn/compression driver assembly provides exceptionally broad distribution of the high end, while the bass driver element is known for impressively high efficiency and durability. The 1230C's eight sturdy, reinforced sides allow for easy and creative positioning to optimize sound dispersion patterns. The unit serves ideally as a compact, on-the-road traveller, and as a highly-efficient, reliable speaker in public address systems. This flexible Altec speaker system is finished in mar-resistant textured black, with matching black textured-knit grille and vinyl edge protectors. Designed for maximum strength and acoustical properties, the enclosure is constructed of 3A" particle board, contains acoustical damping materials, and is solidly braced to complement the theoretical design of the entire system.
