Analog In – DCIO/DCIO-H
The Analog Input for the DCIO (and DCIO-H) has two line-level inputs and an input for a microphone. The connectors are physically part of the DCIO. The Analog Input converts the input signal to processed digital and provides software controls before and after the convertor. Connection for the Mike / Line input is provided via a standard three-conductor XLR connector with balanced input, phantom power available in Q-SYS Designer. Used for: mono, non-sync sources including microphone for in-auditorium announcements, and SPL metering. In addition to the XLR, a standard 3.5mm TRS jack, unbalanced, stereo, analog, line-input.

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 ≈100 to 0 |

Phantom Power |
Toggle turning on and off phantom power (+15VDC) to the microphone. Not available for the Line Inputs. |

Preamp Sensitivity (dBu) |
The maximum analog level, coming into the Analog Input, 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. You can select the field and enter the value you want, or click and drag the number to the value. Varies inversely with the Preamp Gain. |

Preamp Gain knob (Mic Only) (dB) |
The amount of Gain applied to the incoming analog signal level. Varies inversely with the Preamp Sensitivity. |
Default = 0 Range = 0 to 58 |
|||||||||
Preamp Gain buttons (Line Only) |
The amount of Gain applied to the incoming analog signal level. Left and Right toggle buttons toggle the Preamp Gain between 0dB when Off, and 12dB when On. this results in a change in Preamp Sensitivity.
The values of 0dB and 12dB can be seen by connecting a Custom Controls "Text Display" to the Preamp Gain control pin output. |
