What to do if Your Surround Sound System Also Does Equalization
M
ost surround sound systems also perform an automatic optimization of your system. You probably have already done this for your existing
system. When you add in the Digital Drive
PLUS
subwoofer, we recommend you:
1
. Place your subwoofer in its permanent location.
2. Run the Digital Drive

. This gives the surround sound system a nicely bandpassed bass output for blending well to the
s
atellites to use during its automatic equalization process. If you run the sound system automatic equalization routine before you get
the blend correct, the sound system equalization algorithm may turn the subwoofer way down or up due to a peak or dip where the
subwoofer blends to the speakers.
3. Run the surround sound automatic equalization after the Digital Drive

even if you have previously run this before the
subwoofer was added to the system. The surround system automatic equalization now has a smoothly blended bass region for
measurement and should now make the correct choices during its run.
However, due to different automatic equalization systems having different algorithms, you might want to experiment with the opposite
approach; running the surround sound equalization process first and then the Digital Drive
PLUS
EQ. You can compare which order of the
equalization processes gives sound that is most pleasing to you. Also be sure to examine your final settings to be sure that you didn’t end
up with your sound system’s LFE channel set very low or very high and that the level at the Digital Drive
PLUS
subwoofer is the opposite to
compensate. Ideally the channel level will be somewhere near 0 dB and the Digital Drive
PLUS
subwoofer level at or below 50 or 60.
