STA-400D Equipped Subs
e) Using the Manual Speaker Setup menu of your receiver or pre/pro, play the speaker level match-
ing test tone and adjust each speaker to read 75 dB (“5” on the meter with the range switch set to
70) using the speaker trim controls found in the menu for each channel. When playing the test tone
for the subwoofer, use the Gain control on the STA-400D to raise or lower the level of the subwoofer
to read 75 dB leaving the subwoofer trim control in the AVR or pre/pro set to -3 dB. (Note the meter
may fluctuate by several dB when measuring the subwoofer. This is normal and what you are seeing
are room modes in play. Use the average of the swings to determine the volume of the subwoofer.)
If you have two subwoofers, you should split the difference between the two when making level
adjustments. For example, if you need to lower the combined level of the two subs by 4 dB, lower
each sub by 2 dB.
f) From this point forward to add to or decrease the level of your subwoofer(s), use the subwoofer
trim in your receiver. In some cases the level of your subwoofer trim may exceed +/- 5 dB after
tweaking your sub level to taste. If this occurs, use your SPL meter and a combination of the sub-
woofer trim in your AVR or pre/pro and the Gain control on the STA-400D to get the subwoofer trim
back to -3 dB while reading your desired subwoofer level.
