General Function
UUT = Unit Under Test
1)
Connect one pair of speaker cables to either high level input terminal on UUT. Cables should be
connected to an integrated amplifier fed by the signal generator. VOLUME control should be full
counterclockwise.
2)
Turn on generator and adjust so that speaker level output is
2.0V, 50 Hz
. Turn VOLUME control full
clockwise, FREQUENCY control full clockwise.
3)
Green LED should light, immediate bass response should be heard and felt from woofer and port tube
opening.
