generator/sweep
generator
• Integrated
Amplifier
• Multimeter
• Speaker
cables
General Unit Function (UUT = Unit Under Test)
1) From the signal generator, connect line level (RCA) cables 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.
2) Turn the CROSSOVER control to maximum (150).
3) Turn the LEVEL control on the UUT to completely counterclockwise (MIN).
4) LFE/NORMAL switch should be in NORMAL position.
5) PHASE switch position does not matter.
6) Turn on generator; adjust to 75mV, 50 Hz.
7) Plug in UUT; turn the power switch ON. LED should switch from Red to Green.
8) Turn LEVEL control full clockwise (MAX); immediate and vigorous bass response should be heard and felt
