• Fulcrum Acoustic releases DF4 dual horn fill loudspeaker

    Fulcrum Acoustic has released the DF4 Dual High-Frequency Horn, a spot fill passive loudspeaker aimed at supplemental high frequency coverage for areas shaded by venue obstructions.

    The dual four inch diaphragm high-frequency compression drivers are capable of delivering up to 140 dB (RMS, 1W/1m) nominal SPL for long-throw applications. Fulcrum Acoustic’s proprietary TQ™ processing improves the frequency and transient responses. The DF4 is currently available in two models; the DF443 (45° x 30°) and the DF463 (60° x 30°). Enclosures are available in black or white as standard, and custom colors can also e ordered.

    Constant voltage systems (70V, 100V lines)

    Constant voltage, high impedance or line transformer systems are often a somewhat confusing concept for professionals used to rock and roll. They are actually very simple to design, among other things because they are intended to be installed by electricians and the like, with little experience in sound systems. In this article we will try to clarify the simple concepts needed to understand this type of system.... Read more
