Line Out

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.

Controls

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

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

Digital

Control	Function	Default / Range
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

Status

Control	Function	Default / Range
Status	Displays the current status of the amplifier both in text and color. The following is a list of possible status colors, and some example conditions. Note: These conditions are examples, and may not be applicable to all components with a Status field. OK – Green – (0) – Audio is good, hardware is good. Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.) Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.) Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware. Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad. Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.	N / A
