User manual ELECTRO-VOICE TEMP LIMITER V1

[. . . ] 2 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY While this provides tremendous dynamic range and power performance, instantaneous output voltages in these extreme ranges present new challenges to operators and designers to ensure that the loudspeakers are being driven with a safe RMS output level from the amplifier. In order to keep the loudspeakers functioning reliably, tools must be provided to prevent against both mechanical and thermal failures. So, how is the user to know what RMS level they are sending to each speaker?How does the user determine the temperature of their loudspeakers and how safely they're driving their system?The answer is that this is practically impossible for users to do, and that system techs should not have to concern themselves with guesswork about voicecoil temperature. [. . . ] These files are available for download from the Electro-Voice website (http://www. electrovoice. com). These files will be compatible with RCM-26 modules that are operating with V. 1. 15. 0 firmware (or higher) and IRIS-Net V2. 4. 0 (or higher). Additionally, these loudspeaker settings are included in the Speaker Settings folder of IRIS-Net V2. 4. 1 (or higher). Loudspeaker settings with TEMP Limiter parameters can be imported into devices by: o Importing the settings into an individual amplifier o Importing the settings into a Group of amplifiers o Importing the settings via the IRIS-Net Project Generator Instructions for each method are listed below. Importing Loudspeaker Settings into individual Amplifiers 1. If an existing project with TG Amplifier devices is already open, proceed to step # 3. If a new, empty project is open, begin by dragging a Tour Grade Amplifier Object from the Object List into the Project Window. 6 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY 2. In the Amplifier Dialog that appears, select the number of devices, starting CAN address and interface to be used. 3. Double-click on the amplifier object in IRIS-Net to open the Userpanel. In the Userpanel, press the SET button in the lower right-hand corner to open the amplifier's configuration. 7 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY 4. In the Amplifier Setup & Control screen, click on the DSP tab at the top of the window. This will open a block diagram of the RCM-26's DSP structure. 5. Below each output channel, there are buttons to import and export Speaker Settings files. To import a Speaker Settings file with TEMP Limiter parameters, click the IMP button. This will open a dialog which will allow navigation to the location of the file for import. The files are available via the Electro-Voice website or are included with IRIS-Net V2. 4. 1. Navigate to the location of the file to be imported, highlight the file and click Open. 8 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY 6. After loading a SPS file containing TEMP Limiter parameters, you will see an indication in the Limiters block in the DSP block diagram. A green TEMP LED under the block indicates successful loading, while a gray block indicates that the file loaded did not contain TEMP Limiter parameters. In the example below, amplifier Channel A has loaded a . SPS file that does not contain TEMP Limiter parameters, while Channel B has loaded a . SPS file that does contain TEMP Limiter parameters. 9 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY 7. It is possible to get additional information about the behavior of both the PA Limiter and the TEMP limiter by clicking on the Limiters Block in the DSP block diagram. This will open a window that contains detailed information about both limiters, including whether or not TEMP Limiters are active and loaded. [. . . ] When configuring both the PA Limiter and TEMP limiter in this section, it is very important to take note of the amplifier selection for each channel. This selection provides information about the amplifier that is connected to this output that is used to calculate certain parameters for the limiters. A selection of Electro-Voice amplifier models is available for selection, and users are also able to enter their own information for amplifiers not included in the list. For additional information, please refer to the Dx46 User Manual and IRIS-Net Help File. 18 THERMAL ENERGY MANAGEMENT AND PROTECTION LIMITER TECHNOLOGY 6. [. . . ]
