The Whirlwind Cab Driver is an excellent test device for checking speaker components in enclosures. It sends a pink noise signal through push - button selectors to various speaker connectors like Speakon NL8, NL4, 1/4' TS, and banana jacks. You can adjust the pink noise level for different speaker types such as subwoofers, mid - range cones, compression drivers, and tweeters. There's also an XLR line output for self - powered speakers. The DC OHMS TEST button applies 5 VDC to check cone movement and polarity errors, and it performs a DC Ohms test with LEDs showing approximate 4, 8, or 16 Ohms ranges. This helps find blown drivers in complex cabinets. It can be powered by 4 AA batteries or an external 6 VDC power supply (not included).
Using the Whirlwind Cab Driver is easy. First, connect the device to the speaker components you want to test using the appropriate connectors. Then, select the pink noise signal and adjust its level according to the type of speaker. For the DC Ohms test, press the DC OHMS TEST button to check for polarity errors and approximate resistance. When using batteries, make sure to replace them when they run out. If you choose to use an external power supply, ensure it provides 6 VDC. Keep the device clean and dry, and store it in a safe place when not in use. Avoid exposing it to extreme temperatures or moisture.
