Advanced Calibration - DSPeaker Anti-Mode 2.0 Owner's Manual

6.Advanced Calibration

Advanced calibration gives the user more control over the calibration parameters. The
procedure is similar to the typical calibration, but with some additional steps. Refer to
"Typical Calibration" section of this manual for an overview of the basic process.
To perform the advanced calibration, choose the Advanced Calibration option at the
Calibration menu.
➢After choosing the relevant speaker configuration, the extra settings dialog will
appear.
Level compensation affects compensation for wide dips in the bass response.
Compensation has three levels, "Off", "Norm" and "Max". If the setting is "Off",
no compensation to boost dips is applied, and the bass level remains as low as
it would be without room effect. This gives maximum headroom for the user to
design custom boosting filters, such as House Curve or Parametric EQs. The
"norm" setting applies a mild compensation, which is the same amount that
"Typical" calibration is using. This setting usually gives the best audible result as
the perceived level of the bass is closer to the original than with the
uncompensated "Off" setting. In the "Max", maximum compensation is used,
which gives about +2dB more gain for boosting filters. This setting is beneficial
in spaces where part of the problem is the general lack of bass, possibly
resulted by the absence of proper acoustic barriers. It is good to remember that
destructive reflection nulls can not, will not, and should not be attempted to be
corrected by any DSP.
➢Select the desired amount of compensation and press the OK button to proceed.
➢The next dialog controls the time-alignment of channels.
There are three possible options: Auto-detect, Off and Manual. It is advised to
use the auto-detect for subwoofers and "Off" for the full-range speakers, as the
full-range speakers are assumed to be equidistant from the listener. Note that
optimal acoustic delay is not always the same as physical distance to the
subwoofers: because of this the automatic detection is advised to be used
always on subwoofers. If the manual setting is chosen, the compensation delay
for each channel for subwoofers / speakers can be entered to the corresponding
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
