User manual PEAVEY IPS 400

[. . . ] The enclosure corners are reinforced with metal corners, and a powder-coated, perforated metal grille covers the lower half of the system to protect the woofer from external damage. A built-in SA-1 stand-mount adapter accommodates speaker stand use. The low frequencies are supplied by a 15" Scorpion Plus HO woofer with a Kevlar-impregnated cone and a highly linear suspension. [. . . ] This superb driver is coupled to a Quadratic Throat constant directivity waveguide (U. S. Patent #6, 059, 069) to provide smooth, even response, low distortion and good high frequency dispersion. This horn has an asymmetrical vertical polar response, aiming the main energy lobe down 10 degrees so it is aimed at the audience instead of over their heads. This helps reduce ceiling reflections, ensuring greater clarity and gain before feedback. The Rx22 driver features the Radialinear Planar Phase Correction System (U. S. Patent #6, 064, 745), which provides smoother and extended high frequency response. Input connection to the system is made via two 1/4" phone jacks and a four-pin Neutrik in parallel. The internal passive crossover SPTM 5 features Sound GuardTM III tweeter protection circuit and an advanced topology crossover with high performance components to provide high power handling and reliability. Distortion is read from the graph as the difference between the fundamental signal (frequency response) and the desired harmonic. As an example, a distortion curve that is down 40 dB from the fundamental is equivalent to 1% distortion. Mounting This unit is not designed for overhead suspension. The SA-1 stand-mount adapter may be incorporated, and four large rubber feet are included on the bottom for floor use.
