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. The VTX-LZ-K
laser kit consists of two VTX-LZ laser units and one VTX-LZ-PS power supply unit and
is suitable for the installation of a Front-of-House (FOH) Left/Right system (one VTX-LZ
for the FOH Left array, one VTX-LZ for FOH Right array). For detailed array calilbration
and tuning, multiple lasers can be attached to a VTX array to represent circuit-level
coverage and serve as a reference for measurement microphone placement. In this
case, multiple lasers are mounted to the center enclosure of 3-cabinet circuits or the
upper enclosures of 2-cabinet circuits.
PRODUCT DESCRIPTION
The VTX-LZ laser unit has been designed to securely attach to a VTX line array and
when energized using the VTX-LZ-PS power supply unit, generates a bright green ray
of light on-axis with the loudspeaker enclosure that it is attached to. Green lasers are
significantly brighter than red lasers (approximately 20 times more visible) allowing the
VTX-LZ laser to be used over long distances indoors or outdoors.
For strength, light weight and durability, the VTX-LZ unit is constructed with a die-cast
aluminum base plate and a high impact resistance plastic cover. An aluminum-
reinforced connector plate and a machined aluminum mounting assembly with heat-
treated steel quick release pin (QRP) and lanyard attachment complete the assembly.
Internal, physical alignment of the laser unit mounted inside the VTX-LZ housing is
calibrated at the factory to ensure that the laser provides an accurate reference that is
parallel with the on-axis site angle of the enclosure that it is attached to.
The VTX-LZ is powered by the VTX-LZ-PS power supply. The VTX-LZ-PS power supply
unit is made out of a high impact resistance plastic cover with aluminum-reinforced
connector plate and features a weatherproof power switch with metal-housing XLR
connector. The VTX-LZ-PS power supply has an internal rechargeable battery and is
supplied with an AC adapter for charging purposes.
Note: The rechargeable VTX-LZ-PS battery cannot be replaced by the user and must
be serviced by JBL Customer Service or an Authorized Service Center. For any service
questions please contact JBL Customer Service at 1-800-8-JBL-PRO.
A standard 3-pin XLR is used to connect the VTX-LZ-PS power supply to the VTX-LZ
laser unit. Multiple VTX-LZ lasers can be daisy-chained and up to 10 VTX-LZ laser
units powered from one single power supply. VTX-LZ-PS power supply battery life is
approximately 15 hours when powering a single VTX-LZ laser unit and 3 hours when
powering five VTX-LZ units.
