True Peak/RMS Meter
The Meter is an RMS meter used to measure audio signal loudness, expressed in dB. RMS Response Time, Peak Decay Time, Max Hold Time, and Infinite Hold controls are available to change how the readings are displayed. The Meter is capable of up to 256 inputs.
Inputs and Outputs
Note: The number of signal pins is variable and set in the component's Type Property.
Input Pins
Channels
Audio signal pins are represented by a (
) circle, and traditional wiring is represented by a thin black line. You can use Signal Names on audio signal pins.
By default, the True Peak / RMS Meter component is set to a Mono channel, which provides one input and one output. Additionally, you can set the Properties to allow for Stereo, which gives you two inputs and outputs; or you can choose Multi-Channel, which will allow you to choose between 2 and 256 inputs and outputs.
Output Pins
This component does not have any output pins available.
Properties
Level Meter Properties
Meter Type
Selects the type of the meter.
Channels
Type
Sets the type of Channel available for Inputs and Outputs.
Count
Only appears when choosing Multi-Channel as the Type. Sets the number of Channels for Multi-channel. You can choose between 2 and 256.
Graphic Properties
Label
Use the Label property to change the name of the component in the schematic. The Label property defaults to the component name. To learn more about renaming schematic elements, see Organizing Your Design.
Position
The coordinates reference a specific place in the schematic - for example,"100,100" (horizontal, vertical). 0,0 is the upper left corner of the schematic.
Fill
Sets the fill color of the component in the schematic.
Script Access Properties
Code Name
Displays the currently assign name for control access. You can use the auto-assigned name or customize it. Q-SYS will automatically check all Code Names in the design to ensure name is unique.
Script Access
Defines whether the component will be accessible by script and/or externally, or not at all. Choices include All, External, None (default), and Script.
- None (default) - Not accessible by any script, plugin, or by Q-SYS Remote Control Protocol (QRC).
- Script - Can be accessed by scripts, such as Text Controller, Block Controllers, and plugins only.
- External - Can only be accessed by 3rd party controls systems using component commands from the Q-SYS Remote Control Protocol (QRC).
- All - No restrictions, can be accessed by 3rd party control systems via Q-SYS Remote Control Protocol (QRC), or script objects or plugin objects.
Tip: Use Script Programmer Mode to quickly view the Script Access setting directly on the component in the design schematic without the need to disconnect from the Q-SYS Core processor.
Controls
Input
Peak/RMS Meters (1- n) (dBFS)
The meter display has two different readings:
The solid bar represents the RMS or Peak level. The response of this indicator is controlled by the Response Time control.
The thin line represents the maximum level reached by RMS or Peak level indicator. The length of time this indicator stays at the maximum is controlled by the Hold Time control, or the Infinite Hold button.
The display shows from -60 dB to +20 dB, but if you hover the mouse over the meter, the text readout extends from -100 dB to +20 dB.
Peak/RMS dB-linear (dBFS)
The meter display has two different readings:
The solid bar represents the RMS or Peak level. The response of this indicator is controlled by the Response Time control.
The thin line represents the maximum level reached by RMS or Peak level indicator. The length of time this indicator stays at the maximum is controlled by the Hold Time control, or the Infinite Hold button.
The scale is linear and displays from -60 dB to +20 dB, but if you hover the mouse over the meter, the text readout extends from -100 dB to +20 dB.
Peak Program Meters (1- n)
The Peak Program meter registers peaks longer than a few milliseconds in duration, and ignores shorter peaks.
The meter reads 6 to 8 dB below true peak
The meter has a long decay time constant, to allow longer to see the peaks.
The meter has a logarithmic scale giving 4 decibels per division, and a standard reference level of 4 corresponding to 0 dBu.
Configure
Type
Selects the meter type: RMS or Peak.
Available only in True Peak/RMS and True Peak/RMS dB-linear modes as set in the Properties.
Response Time (seconds)
Sets the Level Detector time constant for both attack and decay. This controls how quickly the meters respond to changes in the input levels.
Available only in True Peak/RMS mode as set in the Properties.
Hold Time (seconds)
Sets how long the maximum level marker is held.
Infinite Hold (button)
Keeps the maximum level marker (thin line) at the maximum value reached, until the button is disengaged.
Control Pins
The available Control Pins depend on settings in Properties.
