Cinema Pink Noise Generator
The Cinema Pink Noise Generator produces random frequencies distributed uniformly in each octave band throughout the audio spectrum. At reference, D-Cinema pink noise level is set for 85 dBC at -20 dBFS signal resulting in a 20 dBFS headroom. Standard reference listening position is at about 2/3 of the way back in the auditorium. The resulting constrained dynamic range allows for optimum listening pleasure. Crest factor is around 2 db higher than with the regular Pink Noise Generator.
Schematic Example
In this example, a Cinema Pink Noise Generator is plugged into an Amplifier which is sending the signal to Surround Sound Speakers. The Surround Sound Speakers will then generate Pink Noise.
Note: Using Cinema Pink Noise Generator is a helpful troubleshooting step when used in conjunction with the Signal Injector tool. This enables you to take the Cinema Pink Noise Generator and inject it at a component's audio input or output. For more information, see the Signal Injector topic.
Inputs and Outputs
Note: The number of signal pins is variable and set in the component's Type Property.
Input Pins
This component does not have any input pins available.
Output Pins
Channels 1 - n
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 Cinema Pink Noise 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.
Properties
Cinema Pink Noise Generator Properties
This component has no configurable properties, other than Channels.
Channels
Type
Selects the range for the audio type of inputs. You can choose Mono, Stereo, or Multi-Channel.
Count
Only available when Multi-Channel is selected as the Type. Sets the number of channels. You can choose between 2 and 256 channels.
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
Mute
Mute the output of the Cinema Pink Noise Generator.
RMS Level (dBFS)
Controls the output level. You can also manually enter values for each, from -100 to 20 dB.
