It's a small investment that will generate a large payoff: more satisfied clients, more efficient operations and better recognition for your skill as a sound reinforcement professional. INTRODUCTION Renkus-Heinz Engineering has developed unique approaches to the line array The Isophasic Plane Wave Generator lens shapes high frequency response so that vertical arrays produce a continuous, coherent wavefront whose curvature can be shaped to the audience area by curving the array. The Midrange Diffraction Baffle used in the PN102/LA and PNX102/LA modules moves the woofers' acoustic centers closer together in the horizontal plane to eliminate "coverage collapse" in the crossover region. [. . . ] The optimum angles are often non-intuitive (there is no simple "formula" that says "hang X boxes at 0° vertical splay, then X more at medium splay and X at the bottom with maximum splay. " Designing a Vertical Array with AimWare Define the Venue Define the depth and location of up to three audience areas with independent start and end points. 12 Line Array User's Manual Locate the Array In most venues your choice of location will be extremely limited. Optimize the Array Your goal is to make the frequency response curve as flat as possible while delivering the desired SPL. Use the boxes at the left of the screen to add or remove modules and to set the splay angles. AimWare shows you instantly whether you are getting closer to an optimum design or farther away. For most venues, the entire design process will take less than one hour. Save Your Configuration The final step is to save the design as a file for later recall or modification. You can also import the file into EASE 4. 1 or EASE JR 4. 1 for further evaluation in EASE. 13 Line Array User's Manual SYSTEM SETUP: ELECTRONICS STLA Self-Powered Systems STLA line array modules are self-powered with the PM-3 PowerNet Tri-Amplifier. The Class D amplifier section and the Loudspeaker Specific Processing electronics require appropriate AC power. Audio inputs can be either high-CMRR analog audio inputs with XLR looping connectors or CobraNet digital audio inputs. If a R-Control remote control and supervision network is installed, its connections can be made via a separate twisted pair cable and Phoenix connector or in systems having CobraNet, with the CobraNet connectors. Source Signal Source signal connections to aself-powered STLA array are quite straightforward. Connecting analog signal simply requires one cable from the top module to the snake. Subsequent modules can then be connected using the PM3's looping XLR inputs and outputs. Of course, if you intend to use level shading as part of your array design, you will need to attenuate the inputs to all modules that receive different signal levels. STXLA Externally-Powered Systems STX Amplifier Selection STXLA array modules are tri-amplified. For optimum performance we recommend the X14 Controller and the following power amplifier ratings: LF 1, 000 to 2, 000 watts, RMS @ 4 ohms MF 400 to 800 watts, RMS @ 4 ohms HF 160 to 320 watts, RMS @ 4 ohms All amplifiers must have the same voltage gain.

[. . . ] Laser inclinometer ­ For measuring vertical and horizontal angles in the venue. An ideal product is the Calpac `Laser projecting a dot' version. Carpenter's level ­ used to ascertain the trueness of the surface from which the angle measurements originate. Rangefinder measuring device ­ either a Disto type laser measure or an optical laser rangefinder can be used. [. . . ]
