Line Array User’s Manual Line Array User’s Manual Digital remote inclinometer – with a remote sensor in the bumper and a meter unit at ground level to ensure precise aiming of the cluster. A typical unit for this purpose is the Schaevitz Anglestar. Audio Analysis Software – strongly recommended but perhaps not absolutely essential. SDA EASERA, or SIA SmaartLive, SmaartPro or Spectrafoo enable rapid and detailed analysis of the acoustical performance.

Line Array User’s Manual Line Array User’s Manual Thank you for selecting a Renkus-Heinz Line Array System. This manual is intended to help you obtain optimum performance from your system. Your system is one of the four types described below and on the next page. PN/PNX SY STEMS SYSTEMS Have one operator stabilize the dolly-stacked modules, then raise the array until the tie bars are free of the receiving PN102/LA & PNX102/LA PN102/LA SYSTEMS PN102/LA Self-Powered Line Array Module.
Line Array User’s Manual Line Array User’s Manual STLA/STXLA SY STEMS SYSTEMS The module’s tie bars fit into slots on the sides of the dolly. STLA Line Array Systems STLA/9 Self-Powered Line Array Module. 136 dB peak output, yet under 200 lbs. 2x 12" LF drivers and two CDT1.5 CoEntrant Drivers on an Isophasic Plane Wave Generator. Engineered for use in vertical arrays; integral two-point flying hardware. Self-powered with the PM-3 PowerNet Tri-Amplifier: R-Control optional and CobraNet inputs optional.
Line Array User’s Manual Line Array User’s Manual ALL LA SYSTEMS RH Engineering has developed an acoustic lens of the “path length refractor” type in order to change the output of a horn/driver into a planar wavefront. A schematic of the HF section of a Renkus-Heinz Line Array Module looks like this: For maximum splay (i.e. 5° in “uptilt” position or 4° in “downtilt” position) align the middle hole on the Tie Bar with the bottom hole on the receiving tube.
Line Array User’s Manual Line Array User’s Manual The RHANGSTLA Tie Bar has 3 angle setting positions. THE STLA’S COENTRANT DRIVER The patented CoEntrant Driver integrates the output of a cone transducer and a compression driver into a single high output, wideband point source. Coupling these devices with Complex Conic horns has generated a number of highly effective horizontal array modules – the ST Series of products. The new CDT 1.
Line Array User’s Manual Line Array User’s Manual BASIC VERTICAL LINE ARRAY CONCEPTS Line source coupling only occurs at longer wavelengths/lower frequencies This is because adjacent sources have to be less than 1/2 wavelength apart in order to couple coherently. Audible frequencies have a wide range of wavelengths, from over 50 feet at 20 Hz to about 1/2 inch at 20 kHz. Obviously it’s easy to get two sources to couple coherently at 20 Hz, because the wavelength is about 50 feet.
Line Array User’s Manual Line Array User’s Manual Straight (flat) Line Array Inspect the shackles Curved Line Array Self-powered modules require a signal connection (analog XLR or digital CobraNet). Connect the top module of each group that will receive the same signal first.
Line Array User’s Manual Line Array User’s Manual AimWare provides a visual interface to the complex math behind vertical array optimization If you happen to own a “line array” system and have a week or two in an empty venue to prepare for your next event, feel free to set up multiple measurement systems at, fro example, a dozen points in the audience area.Then experiment with different hang points, aiming angles, number of modules and splay angles.
Line Array User’s Manual Line Array User’s Manual Locate the Array Before attaching the flybar to the top array module, attach the side pieces using the provided quick-release pins. In most venues your choice of location may be extremely limited. Optimize the Array RHANGSTLA hardware is manufactured for Renkus-Heinz by ATM Flyware. To attach the RHANGSTLA fly bar, insert it into the receiving tube and then insert the quick-release pin.
Line Array User’s Manual 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.
Line Array User’s Manual Line Array User’s Manual PN/LA Self-Powered Systems PN/LA modules are self-powered with the PN-1 PowerNet Amplifier. The Class A/B amplifier section and the Loudspeaker Specific Processing electronics require appropriate AC power. Audio inputs are high-CMRR analog audio inputs with XLR looping connectors. If the R-Control remote supervision network is installed, connections can be made via a separate twisted pair cable and Phoenix connector.
Line Array User’s Manual Line Array User’s Manual Rigging Procedures The designs of the RHANG/LA and RHANGSTLA rigging systems have been optimized for the mechanical and acoustical characteristics of Renkus-Heinz line array modules. RHANG flying hardware enables a variety of system configurations to be flown with a minimum number of motor hoists. Vertical angle adjustment between cabinets has been limited to specific settings to ensure proper acoustic coupling.
