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.

---|---|---|
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 |
