[. . . ] Circled in Figure 5. 6) Neatly tie the unused two-conductor wire harness to the panel so it's available if it is ever desired to convert the loudspeaker back to fully passive operation. Indicated by arrow in Figure 4. 5) Plug this four pin connector into the four pin receptacle on the input connector panel. The connector is keyed and will only insert the correct way. Circled in Figure 4. Figure 2 LIMITER CALIBRATION Figure 3 Figure 4 Figure 5 1) Set up your system's gain structure. You will need a sine wave generator (or a test CD with sine waves of various frequencies) and a volt meter. You can use other signal processors with Renkus-Heinz loudspeakers, but in order to protect them from damage, you must do your best to re-create the process Renkus-Heinz Engineering uses to set up the limiters. The following procedure is as close as you can get without access to the specialized equipment we use at the factory. 2) Disconnect the loudspeakers from the amplifier. Do not set the limiters with the loudspeakers connected - you will damage the loudspeakers. This damage is not covered by our warranty! Table 2 3) Feed a sine wave signal into the amplifier. Use a frequency in the lower part of the driver's pass band: 60 Hz for subwoofers, 200 Hz for lows and fully passive speakers, 1 kHz for midranges or mid-highs and 2. 5 kHz for compression drivers. 4) Connect the volt meter to the amplifier outputs. 5) Check Table 2 for the maximum RMS voltage that should reach the loudspeaker based on its Program power rating. Raise the level of the signal generator until the volt meter reads two or three volts above the specified voltage. 6) Reduce the threshold control of the limiter until the voltmeter reading is at or below the maximum from Table 2. Loudspeaker Users Manual Page 4 Loudspeaker Users Manual Page 5 If you do not need the full output of the loudspeaker for your application you can save money by using a smaller amplifier. You will still get the best performance with Renkus-Heinz Loudspeaker Specific Processing. USING THE UNIVERSAL MOUNTING HARDWARE ATTACHMENT POINTS Following the above procedure will provide some protection against overpowering and damaging your loudspeakers. COMPLEX CONIC HORN ORIENTATION If you ordered your loudspeaker with optional u-bracket or speaker mounting hardware, your loudspeaker will ship with flat head bolts installed in the attachment points. These flat head bolts are installed as place holders and are not intended for use with the brackets. Use the bolts that come with the u-bracket assembly to attach the loudspeaker. See the instruction sheet enclosed with the brackets for details. Rotating a Complex Conic horn is easy. Then remove the eight flat head bolts securing the horn to the cabinet. Gently pull the horn out of the cabinet just enough to clear the cut-out, rotate the horn 90 degrees and replace it in the cutout. Finally, reinstall the bolts and the grill. LOUDSPEAKERS WITH TRANSFORMERS INSTALLED Our unique TRue Array Principle design requires that Complex Conic horns be oriented with the narrow angle of coverage horizontal. [. . . ] Some selfpowered loudspeakers have passive crossover networks and these can be inspected in the same manner as well. First, use the mute switches on the amplifier to narrow the problem down to just the component or components that have failed. Self-powered loudspeakers can be checked using most of the same techniques listed above, but with some differences and extra cautions. Some self-powered loudspeakers have removable input and control modules. Swapping these modules from a known good amplifier of the same type can narrow down the problem to an amplifier or module. Be careful when plugging and unplugging ribbon connectors so as not to damage the cable or the connectors or bend any of the pins. If you suspect an amplifier problem do not disassemble the amplifier. There are no user serviceable parts in the amplifier. [. . . ]
