The Mic/Line In provides line-level input for devices with line-level outputs and microphones. The Mic/Line In converts the analog input signal to a digital signal and provides software controls before and after the convertor. Connections are made using two three-terminal Euro style connectors.
The controls listed below are divided into sections to match the Control Panel sections.
Once you establish the initial settings for a component, you can save those settings, along with all the other component's settings, in a Snapshot.

Control |
Function |
Default/Range |
|---|---|---|
|
Frequency (Hz) |
Sets the frequency of the Pilot tone. One control for each channel. |
Default = 22k Range = 10 to 22k |
|
Level (dB) |
Sets the level for the Pilot tone. One control for each channel. |
Default = -60 Range = -100 to 0 |

|
Peak Input Level (dBFS) |
Meters for each channel indicating the peak analog input level. The measurement is taken after the A/D converter, but before the Digital Gain. Use this meter in conjunction with the Max Input Level to obtain an input signal as close to 0dBFS as possible without actually clipping. |
Default = N/A Range = -100 to 20 |
|
Clip |
Red LED indicating if the signal is being clipped. |
Off/On |
|
Clip Hold |
Holds the clip indication until manually cleared. |
Off/On |
|
Phantom Power |
Toggle turning on and off phantom power to the microphone. |
Off/On |
|
Max RMS Input Level (dBu) |
The maximum analog level, coming into the Mic/Line Input card, that can be converted without clipping. This level is typically set slightly higher than the source's output level, so that the Peak Input Level reads about 0 dBFS with. |
Default = 21 Range = 27 to -55 |

|
Invert |
Toggle button to invert the digital output of the Mic/Line input card. |
Off/On |
|
Mute |
Mutes the output signal. |
Off/On |
|
Gain (dB) |
Controls the Gain of the digital output signal. |
Default = 0 Range = -100 to 20 |

Status |
Displays the current status of the card both in text and color. The following is a list of possible status colors, and some example conditions. 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 |
There are no adjustable properties for the I/O-22 Mic/Line In card. However, when the component is selected, you can select some of the Properties available for the entire IO/22 component. For an explanation of these properties refer to the IO/22 Status topic.
The available Control Pins depend on settings in Properties.
