Plug in UUT; red LED should be ON. Turn GAIN control full clockwise. 4. Bass response should be substantial,
9、 and woofer at near maximum excursion.5. Turn off generator, turn VOLUME control fully counterclockwise, disconnect RCA cable.Sweep Function1. Follow steps 1-4 above, using a sweep generator as a signal source.2. Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles,
10、clicks,buzzes or any other noises. If any unusual noises are heard, remove driver and test.Driver Function1. Remove driver from cabinet; detach + and - wire clips.2. Check DC resistance of driver; it should be 8.1 ohms 10%.3. Connect a pair of speaker cables to driver terminals. Cables should be con
