7.2 _MAIN OPTIMIZATION SETTINGS
The Optimizer Main Settings are located in the Optimizer Settings/Settings/Main Settings page.
NOTE: Changes made in the Optimizer Settings do not require new acoustic measurements. The new compensation
filters are recomputed on the fly using the Apply changes button.

Optimize (Optimization Modes): The Altitude
16
offers four different optimization modes with very specific behavior:
• Amp Phase (default): With this setting, the Optimizer will improve both the loudspeaker amplitude and the phase
response of the loudspeaker. This greatly reduces the group delay of the speakers starting from about 150Hz.
• Amplitude only: This mode tells the Optimizer to work only on the amplitude of the loudspeaker’s response. The phase
behavior is not modified;
• Low range only: With this setting the automatic equalization will only use IIR filters up to the frequency defined in the
advanced settings (Default: 150Hz). The automatic FIR filter is disabled but manual FIR EQ can still be applied;
• According to L&R speakers: This is a special mode that will optimize the other speakers in order to achieve the same re-
sponse as the averaged Left+Right speakers. The different options available for this mode are explained in the Advanced
Optimization Settings subchapter.
Maximum Boost/Attenuation:
• Maximum boost: defines, in dB, the maximum amount of boost that will be performed by the algorithms. This parameter
is used to avoid distortion. Its default value is 6dB. This parameter has an important impact on the behavior of the auto-
matic equalization, and is applied to both the time-based and the amplitude-based approach.

• Acoustic parameters “Quantity of Early Reflections” and “Resolution of Energy Response”:
