User Line Enable

Controls: Calibration Menu >> User Units >> User Line
Macro: UserLine

This button has "Enable User Units for:" above it, and the button itself is labeled "LEFT" or "RIGHT" plus the current line name, such as "LEFT Mic". When the button is active, the User Line calibration information in the rest of the dialog will be applied to the indicated line whenever Use Enabled Units (ALT+U) is active in the parent User Units dialog (CTRL+U).

By using the scroll arrows at the top of this User Line dialog you can change to a new line, as shown on this button.

Macro Notes:

If the relevant User Line dialog is open, UserLine=1 will enable, UserLine=0 will disable, and UserLine=x will toggle the enable state.

However, it is usually more useful for a macro to change User Line controls directly, without the dialog open. This requires that you specify which line the macro refers to. This is done via Uxx. prefixes before the macro command.

For Input lines, U0L.UserLine=1 sets Left Input line 0 (counting from the top of the User Units dialog), through U7R.UserLine=1.

If your card has only Master Input lines, UIL. or UIR. prefixes will specify them here.

If your card has only Master Output lines, specify them with UOL. or UOR. prefixes.

Otherwise, UWL. and UWR. prefixes specify Wave Out lines.

If a data file is open, UIL. and UIR. prefixes specify Left and Right Input lines, while UOL. and UOR. specify Output lines.
