Appendix B: Fader Alignment

A comprehensive fader alignment on the MCU Pro and MCU XT Pro is performed at the factory during quality control testing. Then, each time the unit is powered on, the faders complete a quick up-down test to verify that they are still aligned and working correctly. This should provide years of perfectly calibrated faders.

However, on occasion, the faders may need to be realigned. For example, after a firmware upgrade, after enduring extreme changes in temperature or humidity, or after a jarring impact or other fader failure. It’s easy to do; just follow the instructions listed below. Note that this process is identical for both the MCU Pro and MCU XT Pro.

To Align the Faders:

1.Power off the unit.

2.Simultaneously press and hold the Channel 1 V-Pot and Channel 2 V-Pot buttons and power on the MCU Pro or MCU XT Pro.

3.The faders move up, then down, for calibration. The LCD then displays “Entering fader alignment mode...”

4.The LCD displays instructions to align all faders at –40 dB. Do so by moving all faders until the fader’s black center lines up exactly with the –40 dB bold line on the silkscreen. Press the Channel 1 REC button when finished.

5.The LCD will now prompt you to move all faders to the –10 dB mark. When completed, press the Channel 1 REC button.

6.Repeat the process again, moving the faders to the unity (U) mark this time and pressing the Channel 1 REC button one last time. The LCD will indicate that the fader alignment was successful.

The new fader alignment data is written to memory and will be retained, even after the unit has been powered off.
