Page 7: Introduction
INTRODUCTION Precise VTX V25 vertical pattern control requires precise focus for optimum audience coverage and the VTX-LZ laser accessory provides a cost-effective installation tool to help streamline the setup process. Typically a single LZ is installed on the top enclosure of each VTX array to serve as a visual reference while setting the overall array site angle in accordance with JBL Line Array Calculator (LAC) predictions. -
Page 8: Array Trim Height And Site Angle Adjustment
ARRAY TRIM HEIGHT AND SITE ANGLE ADJUSTMENT When properly mounted on the top enclosure of a VTX line array, the VTX-LZ laser provides a visual reference to confirm on-axis vertical site angle aiming (focus) of the array. Coverage simulations based on JBL Line Array Calculator II software (LAC II) indicate the desired location where the laser should aim and the VTX-LZ laser provides visual confirmation to assist with actual installation in the field. -
Page 9: Using Multiple Vtx-Lz Lasers
USING MULTIPLE VTX-LZ LASERS For advanced system tuning, multiple LZ lasers can be deployed to serve as site angle references for individual array circuits, assisting in physical measurement microphone placement to correspond with virtual measurement microphones shown in LAC. Using JBL HiQnet Performance Manager™ control software and with reference to measured spatial response, circuit level gain shading and JBL Line Array Control Panel (LACP) frequency tapering adjustments are performed as a first step in system tuning. -
