Multi-Point (Wide Area) Calibration - DSPeaker ANTI-MODE 2.0 DUAL CORE Owner's Manual

fields. The manual channel compensation delays are meant primarily for more
complex systems, such as a 2.2 system with two Dual Cores or equivalent. In
the Typical calibration, automatic detection of delay is always employed when
calibrating two subwoofers (either stereo or dual-mono) but not in full-range 2.0
mode. You can still use time-alignment and auto-detect for the full-range 2.0
setup by choosing the Auto-detect option. The auto-detection always calculates
compensation to produce the minimum lag, meaning it will only delay the
channel that is "too early" compared to the other, whereas manual adjustment
of the delays allows delaying both channels. This is of course unnecessary for
any systems where all of the audio is going through Anti-Mode 2.0 Dual Core.

Now you can select the upper frequency limit of the automatic correction. Using
the arrow buttons, set the upper limit of the correction between 80 and 500Hz.
Bass signals have no directionality at the lowest frequencies, but they get
directional toward the mid-range bass and above. Because of this, Anti-Mode
2.0 Dual Core employs correction of the summed output on lowest frequencies
(where all audio material is essentially monophonic), but the correction
becomes more channel-dependent towards lower mid-range and higher
frequencies. After all it is a different concept to measure either left or right
channels separately, compared to measuring both in-phase (which applies to
the majority of any bass content). All this directionality versus summed (in-
phase) effects are automatically handled by Anti-Mode 2.0 Dual Core controlled
by the selected correction frequency range.
➢ After selecting the desired settings, press OK button on the remote to proceed to
the volume level check. From here on, the calibration process is similar to the Typical
calibration described earlier.

7.Multi-point (Wide Area) Calibration

The Anti-Mode 2.0 Dual Core features a wide area optimization method which allows
for a larger "sweet spot" to be corrected. Fortunately, wide area algorithm does not
require you to measure dozens of different places around the listening area. In most
cases it should be enough to make the main calibration in the center of the target
listening area, and when it is complete, more points can be added to the calibration
data.
