Mic/Line In (NV-32-H)

The Mic/Line In component represents the AUDIO IN jack on the rear of the NV-32-H.

Input Pins

This component has no input pins.

Output Pins

Channel 1, 2

Each pin represents one channel of stereo audio that you can route to other Q-SYS audio components:

• Channel 1: Left side audio.
• Channel 2: Right side audio.

Core Properties

See the HDMI I/O (NV-32-H) topic for a list of available Network Video Endpoint Properties.

USB Bridging – Common Properties

These properties appear based on the USB bridging capabilities of the Q-SYS device. Refer to the USB Video Bridge and USB Audio Bridge topics to see what Q-SYS Core processors and peripherals support USB bridging.

USB Bridge Name

User-defined name given to the USB Bridge, from 1 to 24 characters. 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.

USB Video Bridge

Enable the USB Video Bridge to bridge Q-SYS Mediacast streams to USB, enabling you to view Mediacast video on a connected computer. This exposes the USB Video Bridge component in the I/O-USB Bridge Inventory tree. To see what Properties are available when the USB Video Bridge is enabled, see USB Video Bridge.

USB Audio Bridge

Provides the capability of passing audio via USB. When this is set to anything except 'Disabled', you can drag the Speakerphone and/or Sound Card components from the device's Inventory tree into your design. To see what Properties are available when the USB Audio Bridge is enabled, see USB Audio Bridge.

• Disabled: (Default)
• Speakerphone (1 x 1): Provides a speakerphone with an input and output component, each having 1 audio connection.
• Sound Card (2 x 2): Provides a sound card with an input and output component, each having two (stereo) audio connections.
• Speakerphone and Sound Card: Provides one speakerphone and one sound card with the same capabilities as described above.
• Advanced – If supported, allows up to any combination of four speakerphone / sound cards.

Speakerphone Mode

This selection is available only when Speakerphone or Speakerphone and Sound Card is selected in the USB Audio Bridge property. Indicates if the Q-SYS design has Echo Canceling (EC) or Non-Echo Canceling (NEC). This information is provided to the PC or Mac operating system so it can determine whether or not to use its own echo canceling.

Graphic Properties

Label

Use the Label property to change the name of the component in the schematic. The Label property defaults to the component name. To learn more about renaming schematic elements, see Organizing Your Design.

Position

The coordinates reference a specific place in the schematic - for example,"100,100" (horizontal, vertical). 0,0 is the upper left corner of the schematic.

Fill

Sets the fill color of the component in the schematic.

Script Access Properties

Code Name

Displays the currently assign name for control access. You can use the auto-assigned name or customize it. Q-SYS will automatically check all Code Names in the design to ensure name is unique.

Script Access

Defines whether the component will be accessible by script and/or externally, or not at all. Choices include All, External, None (default), and Script.

Tip: Use Script Programmer Mode to quickly view the Script Access setting directly on the component in the design schematic without the need to disconnect from the Q-SYS Core processor.

Analog

Peak Input Level (dBFS)

The peak level of the input signal for each channel, from -120 to 20 dBFS. The measurement is taken after the A/D converter, but before the Digital Gain.

Clip

LED indicates if the incoming signal is being clipped.

Clip Hold

Click to hold the clip indication until you manually clear it.

Mic Bias Voltage

If your connected condenser microphone requires it, click to apply mic bias voltage (2.8V DC) to the analog audio channels. This control is similar to Phantom Power, but provides less voltage. Note that this control is linked to both audio channels.

Preamp Sensitivity

Set the incoming maximum analog level that can be converted without clipping, from -38 to +22 dBu (default is +22). You typically set this level slightly higher than the source's output level so that the Peak Input Level reads approximately 0 dBFS with no clipping.

This value varies inversely with Preamp Gain.

Preamp Gain

Select the amount of gain to apply to the incoming analog signal level, from 0 to 60 dB (default is 0).

Digital

Invert

Click to invert the polarity of the digital audio signal output to Q-SYS.

Mute

Click to mute the digital audio signal output to Q-SYS.

Gain

Click to adjust the gain of the audio signal output to Q-SYS, from -100 dB 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.
