Flex In (I/O-8 Flex)

The Flex Channel feature on the I/O-8 Flex provides eight audio channels that can be individually switched between line inputs and line outputs. The Flex Input Component provides the control and selection of the line-level outputs on the I/O-8 Flex. The Flex Input component converts the analog signal to digital and provides software controls before and after the convertor. Connections to a single channel are made using a three-terminal 3.5mm Euro style connector.

Note: The Flex Input and Output components are not for use with QSC DataPort amplifiers.

Input (Enable)

Changes the associated channel to a Flex Input channel.

To switch back to a Flex Output channel, you must enable the channel in the Output Component.

Function

Default / Range

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 0 dBFS as possible without actually clipping.

Default = N / A

Range = -120 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 (+48VDC) to the microphone.

Off / On

Preamp Sensitivity

(dBu)

The maximum analog level, coming into the Flex Input component, 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 without actually clipping.

Varies inversely with the Preamp Gain.

Default = +24

Range = +24 to -48

Preamp Gain

(dB)

The amount of Gain applied to the incoming analog signal level.

Varies inversely with the Preamp Sensitivity.

Default = 0

Range = 0 to 72

Digital

Function

Default / Range

Invert

Toggle button to invert the digital output of the Flex Input component.

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 LED

Multicolored LED indicating the status of the I/O-8 Flex In component. This LED matches the Status text field.

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.
