Line Out (QIO Series)

Use the Line Out component to convert digital audio from your Q-SYS design to analog audio for playback on a device wired to the Line Outputs of a QIO peripheral. For QIO Series Audio I/O Expanders that include Line Outputs, the Line Out component is available within the device's Inventory tree. You can configure audio parameters both before and after the digital-to-analog converter.

Input Pins

Output 1-4

For each Output Channel supported by the QIO device, this pin receives audio from another Q-SYS audio component for output to a connected analog audio device.

Output Pins

This component has no output pins.

In this example, analog audio connected to the line inputs of a QIO-ML2x2 (perhaps from a pair of media players) is equalized and mixed with audio from an Audio Player component. The mixed audio is then sent to the ML2x2's line outputs for playback – for example, to a connected QSC SPA Series amplifier wired to QSC AcousticDesign loudspeakers.

Name

The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.

Location

User-defined name that groups the component with other components in the same physical location, or in the same organizational scheme.

Is Required

When enabled, and the device is not found on the network, the device is reported as 'Missing', which is an error condition. This is the default behavior. When disabled, and the device is not found on the network, the device is reported as 'Not Present', which is not an error condition.

Dynamically Paired

Indicates that this virtual component can be paired with the same type of hardware without changing the network ID of the hardware or the name of this component. Refer to the Q-SYS Core Manager Dynamic Pairing topic for more information. The default is 'No'.

Analog

Peak Output Level (dBu)

Measures the peak output level to the output device, from -120 to 27 dB.

Output Mute

Mutes the output after the D-A converter and before the output.

Max RMS Output Level

Controls the maximum analog RMS output level after the D/A converter, from -37 to +24 (default is +24). 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.

Output Gain

The amount of gain applied to the outgoing analog signal, from -61 to 0 dB (default is 0). Varies in direct proportion with the Max RMS Output Level.

Digital

Peak Output Level (dBFS)

Measures the digital signal level prior to the D/A converter.

Clip

Red LED indicates if the incoming signal is being clipped.

Clip Hold

Holds the clip indication until manually cleared.

Invert

Inverts the polarity of the audio signal.

Mute

Mutes the incoming digital audio signal.

Gain

Controls the gain of the digital audio signal prior to the D/A converter, from -100 to 20 dB (default is 0).

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.
