Line Out (I/O Card)
The Line Out card provides line-level output for devices other than QSC DataPort amplifiers. It is typically installed in an I/O Frame, but can be installed in the Core. The Line Out card converts the processed digital signal to analog and provides software controls before and after the convertor. Connections are made using four three-terminal Euro style connectors.
For hardware information, see COL4 – Analog Line Output Card.
There are no adjustable properties for this component.
Each control listed in the Analog and Digital sections, are one per channel.
Line
Control |
Function |
Default / Range |
---|---|---|
Peak Output Level (dBu) |
Measures Peak Output level to the output device |
N / A |
Relay Mute |
Mutes the output after the D-A converter and before the output. |
Off / On |
Max RMS Output Level (dBu) |
Controls the analog RMS output level after the D/A converter. This level is typically set slightly lower than the destination's sensitivity or maximum input level in order to avoid clipping the signal of a power amplifier. Varies in direct proportion with Output Gain. |
Default = 21 Range = -10 to +21 |
Output Gain (dB) |
The amount of gain applied to the outgoing analog signal. Varies in direct proportion with the Max RMS Output Level. |
Default = 0 Range = -31 to 0 |

---|---|---|
Peak Output Level (dBFS) |
Measures the Digital Signal level prior to the D/A converter. |
Green = good Yellow = close to clipping Red = clipping |
Clip |
Red LED indicating if the signal is being clipped. |
Off / On |
Clip Hold |
Holds the clip indication until manually cleared. |
Off / On |
Invert |
Inverts the audio signal. |
Off / On |
Mute |
Mutes the digital audio signal. |
Off / On |
Gain |
Controls the gain of the digital audio signal prior to the D/A converter. |
Default = 0 Range = -100 to +20 |
