SUB135S Test Set Up and Procedure
SYSTEM AURAL SWEEP TEST
Equipment needed:
•Function/signal generator/sweep generator
•Integrated Amplifier
•Multimeter
General Unit Function (UUT = Unit Under Test)
1.From the signal generator (set initially at 0 volts), connect one line level (RCA) cable to the SUB135S LFE jack on the UUT.
2.Plug in the power cord; turn the power switch ON. LED should be Red.
3.Turn up the generator and adjust to 300mV, 40 Hz. LED should now be Green.
4.Immediate bass response should be heard and felt from port tube opening.
Sweep Function
1.Follow steps 1-4 above, using a sweep generator as a signal source.
2.Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers 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 the + and - wire clips.
2.Check DC resistance of woofer; it should be 3.4 ohms ±10%.
3.Connect 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.
5.Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
Caution: take care to replace the + and - wire clips on the correct terminals, as they are the same size. Red wire should connect to the red dot on the terminal.
