3.2 Level Calibration
3. Play pink noise through your speakers. You should not hear anything yet.

4. Begin slowly increasing the volume of your left monitor until the acoustic level
of the pink noise reaches 82 dB SPL on your SPL meter when measured at your
listening position. Turn off your left monitor and repeat with your right monitor.
If you're using monitors that provide a single level control for both the
left and right side, like the Eris E3.5 or E4.5, play pink noise through both
monitors, increase the volume until your SPL meter reads 85 dB.
Power User Tip: If 82 dB or 85 dB is too loud or too quiet for your room, set the level to
one that is more comfortable for your listening requirements. Just be sure to set the
same level for both the left and the right monitor.
5. Turn your full-range monitors off. If your Sub8 is connected to
the Sub Out on a speaker with a dedicated Sub Out, set the
input volume of your Eris Sub8 to "0" and skip to Step 7.
6. Begin slowly increasing the input volume on your Eris Sub8 until
the acoustic level of the pink noise reaches 79 dB SPL on your
SPL meter when measured at your listening position.
7. Set the lowpass filter on your Sub8 to 130 Hz. This will create a
frequency overlap between your Sub8 and your full-range system.
8. Play pink noise through your full system and experiment with the polarity
switch on your Eris Sub8 to see which position provides the best bass
response. Leave the polarity switch where the bass is the loudest.
