This page provides insights into HOLOPLOT's distinctive visualization of output and input level meters and guidance on effectively interpreting them based on your current workflow stage.
The Input and Output level meters are meant to be used at every stage of the workflow, especially during live performances. They offer insight into the overall performance of the system and provide crucial information to ensure that the system sounds as intended. The visualization of the Output and Input meters is automatically configured based on the arrays and beams defined in the HOLOPLOT Plan. This section in HOLOPLOT Control allows for:
Beams input level monitoring: This displays all beams grouped by audio input, arrays, or preset layers, making it possible to identify connected arrays and their properties.
Output level monitoring: This shows levels at an array level, providing a quick overview and then allowing for detailed monitoring of modules within a selected array, ultimately identifying the beams connected to that module.
System-wide output level monitoring: This aggregates all arrays' output levels into a single view, always visible in the Control Panel.

The Input Metering visualization for beams consists of two peak meters:
Pre-EQ: Beam levels before EQ
Post-EQ: Beam level after EQ adjustments.
Below is a detailed explanation of how HOLOPLOT Control displays beam levels.
The beam's dB scale includes an 18 dB headroom to accommodate the internal DSP of the Audio Modules, allowing for additional EQ adjustments, beam processing, and the combination of signals from multiple audio inputs into the beam.
When the signal reaches 0dB, a peak hold indicator will appear. The system, array, or modules' output level meters will accurately show if a limiter is in place.
Here is how to use the Input Meter tab to monitor beam metering:
To monitor every beam level, go to Metering › Inputs.
Click on a specific beam card to expand the Properties Panel. The panel displays the array(s) connected to the beam and its properties.
The Output Metering visualization considers each individual driver of every module and allows monitoring at various levels, from high-level (system-wide or array) to low-level (individual modules and their connected beams).
HOLOPLOT Control presents distinct levels per driver type:
X1 MD80-S: SUB, LF, and HF.
X1 MD96: LF and HF.
X2 MD30: LF
They are represented in:
Peak meters: Maximum, minimum, and mean values for each passband (SUB, LF, HF).
Limiter values: Maximum, minimum, and mean values for each passband (SUB, LF, HF).
Below is a detailed explanation of how HOLOPLOT Control displays output levels.
Here is how to monitor output meters at different levels of granularity:
Monitor all system's output levels at a glance on the Control Panel.
To monitor output levels for each array, go to Metering › Outputs.
To check the output levels of individual modules within an array, double-click the cards with the array name.
Click on the card with the array or module name to display the Properties Panel with the beams (including input level meters) connected to the selected array or module.
