The CAB DRIVER from Whirlwind is a compact test device that allows you to check the operation of speaker components within enclosures. The device generates a pink noise signal, which is sent to your speaker components. The CAB DRIVER has a number of speaker connectors, which are chosen via pushbutton selectors. The connectors include Speakon NL8 and NL4, 1/4" TS, and banana jacks. An XLR line output allows you to feed the pink noise signal to self-powered speakers. The pink noise level can also be adjusted to the proper levels for use with subwoofers, midrange drivers, and tweeters. The unit also offers a DC Ohms test function, which sends a 5VDC current to the selected output, in order to identify speaker and cabling polarity errors. This test will also activate LED indicators that show whether a component has an impedance of 4, 8, or 16 Ohms. The CAB DRIVER can operate on 4 AA batteries, or an external 6VDC power supply. • Multiple speaker connectors, including Speakon NL8 and NL4, 1/4" TS, and banana jacks. An XLR line output allows you to feed the pink noise signal to self-powered speakers • Simple pushbutton selectors provide easy output connector selection • Pink noise level can be adjusted to the proper levels for use with subwoofers, midrange drivers, and tweeters • DC Ohms test function sends a 5VDC current to the selected output in order to identify speaker and cabling polarity errors • DC Ohms test will also activate LED indicators that show whether a component has an impedance of 4, 8, or 16 Ohms. This helps to identify blown drivers that are in series parallel configurations or in places where they may not be easily observed • Operates on 4 AA batteries, or an external 6VDC power supply
