Line Out (I/O-22)

Properties

There are no adjustable properties for the Line Out card. However, when the component is selected, you can select some of the Properties available for the entire component. For an explanation of these properties refer to the IO/22 Status topic.

Controls

Each control listed in the Analog and Digital sections, are one per channel.

Amplifier

Control	Function	Default / Range
Amplifier	Turns the I/O-22 amplifier on or off for the Speaker output on the I/O-22 hardware. The Speaker output is on Channel 2 only. The amplifier provides a powered output to the "SPEAKER" connector. A line-level output is provided on the "LINE OUT 2" connector. Turning this on or off has no effect on the LINE OUT 2 on the hardware.	Off / On
Limiter Active	This LED is illuminated if the Limiter is active.	Off / On

Analog

Control	Function	Default / Range
Peak Output Level (dBu)	Measures Peak Output level to the output device	Range = 20dB to -100dB
Relay Mute	Mutes the output after the D-A converter and before the output. In addition, the amplifier is turned off.	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 = +10 Range = -10 to +10
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 = -20 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 = 21 Range = -10 to +21

Status

Control	Function	Default / Range
Status LED	This LED changes color to indicate the current status of the I/O-22 Output. See Status for the meanings of the various colors.	N / A
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.	N / A
