• Level display offset: its main utility is to display the level in dB SPL you would measure in the room with a -20
dBFS pink noise feeding the outputs of the Optimizer with a 0dB master level (102,6 dB in our example). To do so,
the system must have been calibrated and the dBC button selected. The Legacy option displays the level accord-
ing to another cinema standard scale with values from 0 to 10.
• Level display offset affects displayed level only and has no impact on the level itself. It cannot be stored in
presets. Without the dBC button pressed, it has the same features as Output SPL adjust except it cannot be saved.
Once the dBC option activated, level adjustment is disabled.
• Output SPL adjust affects both displayed and effective Level. Used along with Level display offset, it allows
you for instance to set a reference level corresponding to a measured 85 dB SPL and to store it into a preset. It is a
typical cinema use.
• Level offset when correction is On : this level offset will be applied when the Acoustic Correction is activated.
• Level offset when remapping is On : this level offset will be applied when 2D or 3D Remapping is activated.
• Master Delay can be used to apply an additional delay to all channels and all presets. It is not stored in the
preset.
• Relative Delay can be used to modify the delay of a preset.
The following latency information is available:
• Processing Latency corresponds to the latency of the processor algorithms. It can be modified by changing the
Optimize setting (Amp Phase has higher latency than Amplitude only) or the Audio Buffer Size (in Setup/
Clock Settings).
• Additionnal DRC Latency : corresponds to the latency of the DRC algorithms.
• Relative Delay is the sum of the master and relative delays of the Processor/Master page.
• In-out Delay is the sum of the Processing Latency, the User-defined delays and DRC latency. For the furthest
speaker, it corresponds to the system’s delay from input to output.
• Acoustic Delay corresponds to the distance of the furthest speaker to the measurement point. When Time
Alignment is activated, all the other speakers will be time-aligned to the furthest speaker.
• Total delay at measurement point is the delay from one input until the sound reaches the measurement point.
!
NOTE: The Master Delay and Relative Delay can be a first approach of a sync lips. Indeed you can set all the speakers to a
value of delay so that the sound will be delayed compared to the video
