The VTX-LZ-V20-MB mount bracket has been designed to securely attach VTX-LZ units to VTX V20 line array systems. When properly mounted on a VTX line array system, 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. The VTX-LZ-V20-MB can be attached to either the left or right side of a V20 enclosure.
