5、tegrated Amplifier Multimeter Speaker cables Initial Control Settings: Power Switch OFF; Filter OFF Crossover Frequency 150Hz (Full CW) Level MIN (Full CCW) Phase, Standby switches do not matter General Unit Function (UUT = Unit Under Test) 1) From the signal generator, connect one line level (RCA)

6、cable to the Subwoofer Line Level Input jacks L/R on the UUT. Use a Y-cable from a mono source if necessary to connect to both inputs. Do not connect to the single, purple SUB input. 2) Turn on generator; adjust to 90mV, 50 Hz. 3) Plug in UUT; turn the power switch ON. LED should switch from Red to

7、Green. Turn LEVEL control full clockwise (MAX) 4) LED should Green; immediate and vigorous bass response should be heard and felt from port tube opening. 5) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable. 6) Connect one pair of speaker cables to Speaker

8、Level input terminal (IN) on UUT. Cables should be connected to an integrated amplifier fed by the signal generator. 7) Turn on generator and adjust so that speaker level input at the amplifier is 1.5V, 50 Hz. Turn LEVEL control full clockwise. 8) Green LED should light; immediate and vigorous bass

9、response should be heard and felt from the port tube opening. Sweep Function 1) Follow steps 6-8 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, clicks, buzzes or any other noises. If any unusual noises are

10、heard, remove woofers and test. Driver Function 1) Remove woofer from cabinet (instructions on exploded view drawing); detach + and - wire clips. 2) Check DC resistance of woofer; it should be 3.3 ohms 10% 3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an inte

11、grated 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. 14 H HK KS SU UB B1 12 2 h ha ar rmma an n/ /k ka ar rd do on n 15 HKSUB12 harman/k
