User manual PEAVEY DPM 3V EPROM INSERTION INSTRUCTIONS

[. . . ] The DPM 3V's shape helps reduce the build up of standing waves inside the enclosure, which minimizes mid-bass and mid-range coloration. It is constructed of premium 18 mm poplar plywood and covered with a tough, durable, black textured Hammer HeadTM polyurethane coating. A 16-gauge, powder-coated, perforated metal grille covers the front of the system to protect the speakers from external damage. [. . . ] The 15" Pro Rider woofer features a Kevlar® impregnated, water-resistant treated cone and dust cap for superior environmental stability. An RX22 2" titanium diaphragm compression driver handles the high frequencies and features the Radialinear Planar Phase Correction System (U. S. Patent 6, 064, 745), which provides smoother and extended high frequency response. This driver and the specially-developed, ferrofluid-cooled 6. 5" mid-range driver are loaded by the CH-746qt Quadratic Throat Waveguide (U. S. This device provides unparalleled clarity and low distortion through the mid and high frequency portions of the audio spectrum. Full-range input to the system is made via two 4-pin Neutrik® jacks in parallel. A 4-pin Neutrik switching jack provides biamp input flexibility while maintaining superior signal integrity. The inclusion of a standard 4-pin Neutrik jack in parallel on the driver side of the bi-amp switching jack allows daisy-chaining to another cabinet for bi-amp operation. The internal passive crossover features the Sound Guard III high frequency driver protection circuit and an advanced topology crossover with high performance components to provide high power handling and reliability. This rating is conditional upon having a minimum of 3 dB available amplifier headroom. Harmonic distortion Graphs representing second and third harmonic distortions vs. frequency are plotted in Figures 3 and 4 for two power levels: 10% of rated input power and either 1% of rated input power or 1 Watt, whichever is greater. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. For example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. Mounting Caution: This loudspeaker system is not designed for overhead suspension. Architectural and engineering specifications This loudspeaker system has an operating bandwidth of 50 Hz ­ 16 kHz and a nominal output level of 96. 0 dB when measured at a distance of 1 meter and an input of 1 Watt. It has a maximum continuous power handling of 1, 000 Watts, maximum program power of 2, 000 Watts and a peak power input of at least 4, 000 Watts, with a minimum amplifier headroom of 3 dB. The nominal radiation geometry is 85° in the horizontal plane and 45° in the vertical plane.
