Congratulations on choosing PROJECTOR, a three-way active sound reinforcement system with the power of a large PA and the advantages of state-of-art active electronics. Not only is it easy to transport, you'll also find that it takes no time at all to set up and connect PROJECTOR. These advantages and its remarkable ease of use make PROJECTOR a professional sound reinforcement system well-suited for larger events. [. . . ] LF LIMITER LED Indicates the operating status of the limiter. Green = signal present, yellow = soft limit, red = full limit. NOTE: This is not a clipping indicator; it is acceptable for it to light up every now and then in red. This tells you that the limiter is operating at full capacity. GROUND Ground lift switch for separating the signal and chassis ground from each other when you encounter problems with hum due to ground loops resulting from duplicate paths to ground. The connection from signal ground to chassis is interrupted when you press this button in. 8 9 7 PROJECTOR MANUAL 2. SETTING UP THE SYSTEM 2. 1 Standard System Setup/Stacking: SUB 1 ­ SUB 2 ­ MID-HIGH UNIT!Here's how you set up the standard system configuration: Always set up the cabinets as illustrated in the diagram. Set SUB 1 on the floor, SUB 2 on SUB 1, and the MID-HIGH UNIT on top of the stack. In this configuration, the subwoofers form a full horn and provide the greatest possible output. 2. 2 Standard System with Tilt Unit PROJECTOR Tilt Unit (Cabinets with serial number 317961 and higher are factory-equipped with mounting units. For all PROJECTOR cabinets with lower serial numbers HK Audio provides a retrofit kit with instructions and all required parts. ) The Tilt Unit (see the diagram) is a practical tool designed to assist in aiming stacked PROJECTOR MID-HIGH UNITS directly at the area that you want the system to cover. This ensures that the sonic energy projected by the system can be used more effectively. The Tilt Unit offers three angles of tilt: 5°, 10° and 15°. These options let you adjust the MID-HIGH UNITS to match the venue and the given position of the PROJECTOR system. For example, if the system is set on a relatively high platform (one meter or higher), you should select tilt angles of 10° or 15° for shorter distances, and 5° for longer distances (e. g. If the system is set on a low platform, for example at a height of 0. 2 to 0. 6 meters (1 - 2 ft. ), you should tilt the mid-high units at an angle no greater than 5° to 10°. 35 m 8m tilt 0° 6m refl ecti on Stage 6m 23 m 35 m 10 m tilt 5° 6m refle ction Stage 5m 30 m 35 m 14 m If at all possible, be sure to place the system on a raised platform or stage so that the mid-high unit is situated above the heads of the audience. We recommend a platform with a height of about 2 to 3 feet, or 0. 5 to 1 meters, depending on the size of the venue and how far you want the system to project. The rule of thumb is, the longer the venue or greater the distance you want to cover, the higher you should position the MIDHIGH UNITS. Please follow the instructions on setting up the PROJECTOR components SUB 1, SUB 2 and MID-HIGH in section 2. 1. A A A Note: To prevent phase cancellation, place the PROJECTOR system so that the side panels are set at an angle of 25° relative to each other. The edges of the back panels should be set to the same height and they should touch each other. A distance of some 30 cm (1 ft. ) between the two front faces of the cabinets will give you an angle of 25°. 25° This 25° angle is the best possible compromise for the majority of applications. Angles between 20° and 30° are possible, depending on local factors such as the height, depth or width of the venue and the distance between the loudspeakers and the walls. 9 ENGLISH PROJECTOR MANUAL 3.
