Limit Controls feature

The Limit Control feature can be used to set pre-determined ranges on which our calibration is applied and to what extent. With this feature, you can choose the ceiling for the maximum boost applied by calibration, which is derived from the measurement itself. 




Limit Controls settings

Limit Control in SoundID Reference consists of three variables. 

  • Calibration: Normal (12dB), Reduced (6dB) & No boost (0dB)
    Note: The Safe Headroom adjusts accordingly. If no boost is applied, it will stay at 0dB.
  • Max low frequencies: Reduced, Neutral, Extended, Aggressive 
  • Max high frequencies: Neutral, Extended, Aggressive

With the 'Calibration' selection, you can choose to what extent the freq. are boosted, to match the Flat Target. There are different schools of thought regarding what works best. The default setting is how we intend the calibration to run. We recommend trying different settings to hear for yourself what works best in your scenario. Max high and low frequencies enable you to adjust the set ranges to which the calibration is applied to the low and high ends of the freq. range. More controls can be accessed in the Custom Target mode. 




Reduced, Neutral, Extended, Aggressive

  • Reduced - Applicable to the max low freq. only. For speakers that can't reproduce boosted low-end freq.
  • Neutral - The default setting.  
  • Extended - Enables the user to have more boosted freq. on either the low- or high-end.
  • Aggressive - For the most severe range with boosted freq. Not all speakers might be able to reproduce the boosted freq., especially on the low end.

A use-case scenario is when there is a roll-off in the simulated-after curve. This means either the high- or low-end is not completely aligned with the Flat Target. Set it to Aggressive to compensate for this.
