Amp Output (DataPort Amplifiers)
This topic covers the Amp Output component for QSC DataPort amplifiers, including CX, DCA, and PowerLight models.
Note: DataPorts on multi-port amplifiers must be wired to DataPorts on the same I/O Frame or Core. You cannot wire some of the amplifier's DataPorts to a Core and others, on the same amplifier, to an I/O Frame. You cannot wire some of the amplifier's DataPorts to one I/O Frame and others, on the same amplifier, to another I/O Frame.
Inputs
The inputs are digital audio connecting to loudspeaker components. Loudspeaker signal pins are represented by a left-pointing () triangle, and the wiring is represented by a thin orange line.
Outputs
The outputs are digital audio connecting to loudspeaker components. Loudspeaker signal pins are represented by a left-pointing () triangle, and the wiring is represented by a thin orange line.
Amp Output Dataport Properties
Name
User-defined name given to the amplifier.
Location
User-defined name that groups the amplifier with other components in the same physical location, or in the same organizational scheme.
Model
The Model of the amplifier - The Model is selected when you add an amplifier to Inventory, when you place the amplifier component in the Schematic, it retains the Model information. In the Properties you can change the Model if you need to.
Mode n-n1
Choose if channels n and n are to be in the Stereo mode or the Bridged mode. This setting is to reflect the physical amplifier's setting.
1The DataPort amplifiers support Bridged, Parallel and Stereo modes. Q-SYS supports amplifier modes Bridged and Stereo only. Parallel mode supplies the same signal to two channels by connecting both channel inputs to a single source. In Q-SYS, Parallel mode is accomplished by sending the same signal to two channels on the DataPort card. One DataPort cable carries two channels, so effectively there is no difference if you connect the channel inputs at the amplifier or in Q-SYS.
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.
Amplifier Status
Status
Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:
- OK: The device is functioning normally.
- Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
- Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
- Missing: The device cannot be discovered.
- Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
- Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
- Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.
On / Standby
Button controls the amplifier from Standby to Power On.
Meter Select
Selects either RMS or Peak for the five meters in all channels.
Channel n Status
Mute
Mute button mutes the associated channel of the amplifier. Linked to the Mute button on the associated band of a loudspeaker.
Atten. Pot. (dB)
Setting of the Attenuation Potentiometer on the front panel of the amplifier.
Temperature
Temperature reading of the channel in - Centigrade.
Bridge
The amplifier must be connected and the On state for the Bridge and Parallel LEDs to work properly.
Yellow LED indicating that channel is in the Bridge Mode.
When this LED and the Parallel LED are off, the amplifier is in Stereo Mode. When they're both on, the amplifier is in Bridge-Parallel mode.
DAC Limit
LED indicating that signal to the D to A Converter is larger than can be reproduced and a limiter has been engaged to prevent clipping. This is an indication that the gain structure is not correct.
Protect
LED indicating that the channel is in Protect Mode. Usually due to attempting to drive too low an impedance for too long.
Clip
Yellow LED indicating that the channel is clipping.
Parallel 1
The amplifier must be connected and the On state for the Parallel and Bridge LEDs to work properly.
Yellow LED indicating that channel is in the Parallel Mode.
When this LED and the Bridge LED are off, the amplifier is in Stereo Mode. When they're both on, the amplifier is in Bridge-Parallel mode.
1When an amplifier is in Bridge Mode, the Parallel LED on the amplifier is lit along with the Bridge Mode LED. This LED is reflecting what is seen on the amplifier. See the note in the Properties table for Mode n-n.
Channel n Meter
Input (dBFS)
Measures the analog input to the amplifier channel (output of the DataPort card after the signal has been converted to analog). This reading can be RMS or Peak depending on the Meter Select setting for the associated channel.
The meter in the DataPort component displays the Peak Digital output before the D to A Converter.
Voltage (V)
Measures the voltage of the amplifier / loudspeaker circuit. This reading can be RMS or Peak depending on the Meter Select setting for the associated channel.
Current (A)
Measures the current of the amplifier / loudspeaker circuit. This reading can be RMS or Peak depending on the Meter Select setting for the associated channel.
Power (W)
Measures the power of the amplifier / loudspeaker circuit. This reading can be RMS or Peak depending on the Meter Select setting for the associated channel.
Headroom (dB)
Measures the amount of headroom left before reaching the amplifier's maximum capabilities.
Channel n Monitor
Listen
Enables and disables the loudspeaker monitor.
This is a radio type button and is linked to all other Listen buttons in your design. When this is engaged, all other Listen buttons disengage.
You can only listen to one amplifier channel at a time. In the loudspeaker components, you have the option to listen to one, all, or any combination of bands.
You must have the Loudspeaker Monitor component in the Schematic and properly connected to make use of the monitoring capability.
Note: The Monitor buttons are not linked in Emulate mode. Your design must be in Run mode for the functionality described above to operate.
Gain (dB)
Controls the gain of the monitor. This control has effect only when the Listen button is engaged.
The available Control Pins depend on settings in Properties.
