The VTX-LZ laser unit has been designed to securely attach to VTX or VERTEC line array systems using cabinet specific Mount Bracket (MB) accessories (supplied separately). When energized using the VTX-LZ-PS power supply unit, VTX-LZ generates a flashing bright green ray of light on-axis with the center of the loudspeaker enclosure that it is attached. This provides an accurate site angle reference for system installation or measurement microphone placement for system tuning. Green lasers are significantly brighter than red lasers, allowing the VTX-LZ laser to be used over long distances indoors or outdoors. The VTX-LZ includes IN and OUT (Female / Male) 3-Pin XLR connector for easy connectivity with multiple VTX-LZ laser units using standard microphone cables. Up to 10x VTX-LZ lasers can be used with 1x VTX-LZ-PS by using the IN/OUT XLR connectors.
