STA-800D/1000D Equipped Subs

crossovers set no lower than 80 Hz (a speaker set to Small – as opposed to Large or Full Range – will cause bass frequencies below the selected crossover to be routed from the speaker to the subwoofer).

a)Make sure you have a known good battery in the SPL meter (use the Battery Function). Set the “Weigh- ing” switch to “C”, and the “Response” switch to “Slow”.

b)Set the “Range” dial to “70” to start. Consequently, when the meter displays “0”, that will indicate 70 dB. When the meter reads “5”, that will indicate 75 dB. When the meter reads “-3” (left of “0”), that will indicate 67 dB.

c)In the AVR or pre/pro speaker setup menu, set the value of the subwoofer trim to -3 db. Set the Master Volume (main volume control) of the AVR or pre/pro to 0.0 dB. In most units, this will produce a reading of close to 75 dB on the SPL meter when playing the test tones on your speakers.

d)Place the SPL meter in your main listening position, ideally on a tripod (the Radio Shack SPL meter will mount to a standard camera tripod adapter) with the unit pointed straight up (microphone pointed at the ceiling). Adjust the tripod so the microphone is roughly at ear height.

e)Using the Manual Speaker Setup menu of your receiver or pre/pro, play the speaker level-matching 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 VOLUME control on the STA-800D/STA-1000D 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 first set each sub to 75 dB with the other off, then split the differ- ence between the two when making level adjustments with them both on. For example, if you need to lower the level of the combined 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 subwoofer Trim in your AVR or pre/ pro and the VOLUME control on the STA-800D/STA-1000D to get the subwoofer Trim back to -3 dB while reading your desired subwoofer level on the SPL meter.
