Specifying Units Parameters in the Apogee Setup Dialog

The Units parameters configure the individual hardware units in your system. They are spread over three tabs: General, Inputs, and Outputs.

General Tab

The settings in this tab control a variety of features, such as the clock source, UV22HR dithering algorithm, and level meter behavior.

Sample Rate Conversion
Level Meters
  • Hold Overloads checkbox: If you select this checkbox, your hardware displays overloads permanently.
  • Clear Overloads button: Clicking this button resets the overload LEDs of your meters.
  • CD Mode checkbox: Selecting this checkbox turns on CD mode, which sends a 44.1 kHz, 16-bit stereo signal to the S/PDIF output, regardless of the input. In effect, selecting this checkbox automatically switches the Conversion pop-up menu to S/PDIF Out, the Sample Rate pop-up menu to 44.1 kHz, and the UV22HR pop-up menu to S/PDIF Out. If any of these automatically set parameters are then changed manually, the CD Mode checkbox is automatically disabled.

Inputs Tab

This tab is used to configure the inputs of your Apogee hardware. The tab contains four identical parameter sets for microphone inputs 1 to 4 and a parameter section for line inputs 5 to 8.

Pre-Amp Parameters for Inputs 1 to 4

Inputs 1 to 4 feature built-in pre-amps. These can be configured individually via the four identical sets of Pre-Amp parameters.

  • Gain slider: Sets the gain level of the chosen input (only available for microphone channels).
  • Soft Limit checkbox: Select to apply Apogee’s soft limiting to the inputs.
  • Phase Invert checkbox: Select this checkbox to reverse the phase of the input signal (available only if the channel is used as microphone input).
  • 48V Phantom Power checkbox: Select to activate a 48-volt phantom power supply for inputs 1 to 4. This checkbox is available only if the channel is used as a microphone input.
Analog Line Parameters for Inputs 5 to 8

The Analog Line Inputs section offers the following parameters for line inputs 5 to 8:

  • Soft Limit checkbox: Select to apply Apogee’s soft limiting to the analog line inputs.

Outputs Tab

This tab is used to configure the outputs of your Apogee hardware.

Headphones Parameters

These options configure the output signal for the headphone outputs.

  • Level slider: Sets the level of the headphone outputs.
Main Parameters

You can choose the output channels that you wish to control with the Main Level slider.

Analog Line Output Level Settings

You can set the reference level for each of your eight analog line outputs.
