Application Guide 137327-3A 09/05 2 I-Tech Application Guide Introduction This application guide provides useful information designed to help you best use your new Crown® I-Tech Series amplifier. It is designed to complement your amplifier's Operation Manual, which describes the specific features and specifications of your amplifier. [. . . ] Use the TCP/IQ Utility program to load firmware into your amplifier. 3. 5. 1 TCP/IQ Utility TCP/IQ Utility allows you to update the firmware of your TCP/IQ component as they are made available. The program also serves as a setup and troubleshooting tool for TCP/IQ IQ Networks. Open the TCP/IQ Utility program by choosing it under Start > Programs > IQ Systems > IQwic > TCP/IQ Utility. Application Guide 14 Note: The following procedures assume you have already established TCP/IQ network communications between your PC and your I-Tech amplifier(s). Refer to the help files in IQwic software for help in setting up your IQ Network. Before you begin, save a copy of provided firmware files to a local disk. You may have one or two files, depending on whether you are updating front panel, DSP, or both. Section 3: I-Tech Settings 3. 5. 2 Front Panel Firmware · Open TCPIQ Utility. · Navigate to local folder where you saved the firmware file(s). · Select "ITDAPP_x, " where x represents the version number. Click "Open. " · A window will appear to indicate the progress of the firmware download. When the text "verify ok" appears on the screen proceed to the next step. · Cycle amplifier's power and wait for it to come back online. Figure 3. 11 "Send Code" Function in TCP/IQ Utility 3. 5. 3 DSP Firmware Note: Downloading new DSP firmware will dissrupt audio AND restore factory defaults. All filters and other DSP settings will be turned off and set to factory defaults. · Navigate to local folder where you saved the firmware file(s). · Select "ITA_x, " where x represents the version number. Click "Open. " · A window will appear to indicate the progress of the firmware download. When the progress indicator shows 100% and the text in the firmware download window disappears, cycle the amplifier's power and wait for it to come back online. Application Guide Section 4: I-Tech and JBL VerTec 15 4 I-Tech and JBL VERTEC Crown I-Tech amplifiers and JBL VERTEC Line Array loudspeaker systems make a powerful combination. With them, you can deliver a sound that is very loud, clear, and natural, with uniform controlled coverage. This section provides recommendations for matching I-Tech amplifiers to VERTEC loudspeakers, and how to properly wire them. The examples shown are basic building blocks of a complement of VERTEC elements, along with the appropriate I-Tech amplifiers to drive them. You can design your system with these suggestions used in multiples to build the size of line array you need for your application. With I-Tech's studio-grade, on-board DSP and factory furnished speaker-modeling presets designed for VERTEC, setting up your system has never been easier. [. . . ] In addition, the I-Tech amplifier has a delay of ~85ns in its active digital loop-thru. To put this in perspective, a system with 50 meters of cable and sixteen amplifiers all looped through each other would have a delay at the last amplifier of 1. 575us. This additional source of delay will be inconsequential in almost all systems and can be ignored. Yes, many different sensitivities and gains are available depending on the setting of the max input level switch. [. . . ]
