7.1.8 _MASTER CONFIGURATION
In the Processor/Master menu, you can set some parameters relative to the master of the device.
Figure 109: Master levels and delays
The following options are offered in order to adjust levels and delays for all channels at the same time:
• Master Level is the reference level used by the processor for all presets. It affects both displayed and effective Level but it
is not stored with presets.
• Relative Level may be used to match different presets subjective levels since it can be saved. Therefore you could for
instance carry out proper A/B comparisons between different settings such as Optimization On/Off. It does not affect the
displayed level (on the top left corner of the screen).
• Level display offset: its main use 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 according to another cinema stan-
dard 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 is activated the dBC button pressed, it has the same features as Output SPL adjust
except it cannot be saved. Once the dBC option activated, the 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.
• Additional 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 delay of the system 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 the 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 synched to the video.
