Use the

arrow buttons to highlight the test tone you want to play, then press
SEL
to play it. Play
each of the test tones and use a sound-level meter to measure the volume from the usual seating area. Set
the meter for C weight and slow response. Graph the volume at each played frequency in the chart below.
To stop a test tone, press the
MENU
button. When you’re done playing all the test tones, press the
MENU
button twice to return to the DVD’s main menu.

After graphing the volume of each frequency, locate the frequency on the graph where the volume is the
highest. Set the
FREQ
switch on the back of the subwoofer to that frequency.
Note
This switch does not set the crossover frequency, which is built into the system.
9
Calculate the average of all the measured volume levels and draw a line across the graph at that height.
10
Calculate the difference (in dB) between the peak volume and the average volume. Then turn the
LEVEL
switch to the corresponding –dB setting, based on your calculation. This will reduce the volume of the
peaking frequency and make it nearly equal to the others.
