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.

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. |
Refer to amplifier documentation. |
Temperature |
Temperature reading of the channel in - Centigrade. |
Refer to amplifier documentation. |
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. |
Refer to amplifier documentation. |
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. |
Refer to amplifier documentation. |
Protect |
LED indicating that the channel is in Protect Mode. Usually due to attempting to drive too low an impedance for too long. |
Refer to amplifier documentation. |
Clip |
Yellow LED indicating that the channel is clipping. |
Refer to amplifier documentation. |
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. |
|
1. When 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. |

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. |
N / A |
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. |
N / A |
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. |
N / A |
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. |
N / A |
Headroom (dB) |
Measures the amount of headroom left before reaching the amplifier's maximum capabilities. |

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. |
Off / On |
Gain (dB) |
Controls the gain of the monitor. This control has effect only when the Listen button is engaged. |

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. |
All amplifiers available from QSC for Q-SYS, Choose from the drop-down list. |
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. |
Stereo Bridged |
1. The 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. |
