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

This button is only present for Input lines. It is only enabled if the line has calibrated attenuators, and only if a Spkr .CAL file has been loaded for the Output line on the same Left or Right side.

This button applies the Spkr .CAL output correction to the input line, such that the input response is compensated for the driver response. In other words, if the input line had a mic with a perfectly flat frequency response (or was corrected via its own Mic .CAL file), then it would show a flat overall response to the speaker output, even though the true output wasn't flat itself.

A typical use for this option is for transfer calibration, where you use a calibrated reference microphone to calibrate other microphones.

Macro Notes:

If the relevant User Line dialog is open, UserSpkr=1 will activate, UserSpkr=0 will deactivate, and UserSpkr=x will toggle the button state.

However, it is usually more useful for a macro to change User Line controls directly, without the dialog open. This requires that you use Uxx. prefixes before the macro command to specify which line the macro refers to, as in U0L.UserSpkr=1.

U0L. through U7R. specify Input lines 0-7 and the Left or Right channel of each.

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.
