4、cessory:Bass Optimization Test turn the power switch ON. LED should be Red. Turn LEVEL control full counterclockwise (10) 5.LED should now be Green; immediate bass response should be heard and felt from rear port tube opening. 6.Turn off generator, turn LEVEL control fully clockwise (0), disconnect

5、RCA cable. 7.Connect one pair of speaker cables to Speaker Level input terminal on UUT. Cables should be connected to an integrated amplifier fed by the signal generator. 8.Switch Input to “Speaker”. 9.Turn on generator and adjust so that speaker level input at the amplifier is 2.2V, 30 Hz. Turn LEV

Sweep Function 1.Follow steps 7-10 above, using a sweep generator as a signal source. 2.Sweep generator from 20Hz to 20kHz. Listen to the cabinet and drive

7、rs for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofer and test. Driver Function (Woofer) 1.Remove woofer from cabinet; detach + and - wire clips. See page 12 for removal instructions. 2.Check DC resistance of woofer; it should be 3.4 ohms10%. 3.Connec

8、t a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V. 4.Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.

9、 IL120s ADJUST BIAS PROCEDURE (Mandatory when any output MOSFET transistors Q3,4,7,8 are replaced) 1. Amplifier should be unplugged and OFF. 2.
