SYSTEM AURAL SWEEP TEST

Equipment needed:

Function/signal generator/sweep generator

Integrated Amplifier

Multimeter

Speaker cables

General Unit Function (UUT = Unit Under Test)

Switches/knobs on the amplifier faceplate:

Low Pass Frequency Adjust full CW (150Hz)

Phase switch – either position

1.From the signal generator, Connect both right and left line level inputs (RCA) – not the LFE jack - to signal generator and UUT. Use Y-cable if necessary from mono source.

2.On the amplifier, turn the LEVEL control full Counterclockwise (Min).

3.Turn on generator, adjust to 100mV, 50 Hz.

4.Plug in UUT; turn the power switch ON. Turn LEVEL control full Clockwise (Max).

5.LED should now be Green; immediate bass response should be heard and felt from rear port tube opening.

Sweep Function

1.Follow steps 1-5 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 + and - wire clips.

2.Check DC resistance of woofer; it should be 4.4 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.

4.Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
