INTRODUCTION Thank you for purchasing ISP Technologies HIGH DEFINITION LINE HDL3112 speaker system. The HDL 3112 is a high output three-way active speaker system designed to deliver HI-FI sound quality for medium and high SPL sound reinforcement applications. The HDL 3112 is a single element line array cabinet available in two maximum vertical coverage angles, either 8 degree or 15 degree, with adjustable splay angles.
circumstance. None of the information presented herein is intended as a representation of warranty on the part of ISP Technologies. Anyone making use of this information assumes all liability arising from such use. All information presented in this manual is based upon materials and practices that are most common to The United States of America and may not directly apply to other countries because of differing material dimensions, specs, and/or local regulations.
REAR PANEL CONNECTION DIAGRAM The HDL 3112™ rear connection panel provides both a single ETHERCON input connector, which includes all 3 input signals via a shielded CAT-5 connector and a single XLR Full Range input. The XLR Full Range input is processed internally to provide the correct crossover points for the HDL3112. A Full Range Level adjustment is provided to adjust the level of each individual HDL3112, note: this level control only works for the Full Range input.
The rear panel of the HDL 3112 also has the AC power connections allowing connection to AC power with a Neutrik PowerCon inlet connector. Under the Power input is a Neutrik PowerCon outlet connector, which allows connection to one additional cabinet. It is not recommended to connect more than one additional cabinet to this PowerCon outlet to reduce the possibility of overloading a single AC power circuit and also to avoid excessive current required from a single AC PowerCon inlet.
In a flown configuration the cabinet angles are set by sliding the link from the top cabinet down into the slot of the rear hinge on the next cabinet and inserting the quick release pin in the proper hole selection for the desired splay angle. In a ground stack configuration, simply select the desired splay angle and pin the link into the proper hole. You then insert the additional quick release pin into the ground stack hole in order to obtain the desired splay angle.
