Changing Modes

MCU Pro has three different modes of operation:

  1. 1. Mackie Control (use with most DAWs.
    2. Logic Control (use with Apple Logic).
    3. HUI (use with Avid Pro Tools, including HD, LE, and M Powered versions).

When first turning on the MCU Pro, the display prompts you to select a mode of operation:

  • Press Ch. 1 V-Pot to select Mackie Control.
  • Press Ch. 4 V-Pot to select HUI.
  • Press Ch. 8 V-Pot to select Logic Control. Once the selection has been made, MCU Pro will automatically boot into the selected mode each time it is powered up.

To chnge the mode of operation:

  1. Turn off the Mackie Control.
  2. Hold down both the Ch. 1 and Ch. 2 SELECT buttons while turning on the Mackie Control.
  3. The display once again prompts you to select a mode of operation.

Installation

There are two methods for connecting the MCU Pro to a computer: USB and MIDI. Note: The USB method is the preferred method because all of the MIDI ports on the MCU Pro are available. If using MIDI cables to connect the MCU Pro to a computer via third-party MIDI interface, the other two MIDI ports (3 and 4) on the MCU Pro are inactive.

Connecting with USB

  • Connect the MCU Pro to a computer with a USB cable (see “Hookup 1: USB” on page 6). The USB connection works with both Macintosh and PC platforms and is “plug and play” (no driver installation required!).

Connecting with MIDI

  • Connect the MCU Pro to the MIDI interface via two MIDI cables (IN and OUT). Use the MIDI 2 (MAIN) MIDI connections on the MCU Pro.
  • Connect the third-party MIDI interface to the computer as described by the manufacturer (see “Hookup 2: MIDI” on page 6).

For both methods:

  • Connect one end of the external power supply to the MCU Pro, and the other end to an AC power source between 100 VAC and 240 VAC (50–60 Hz).
  • Turn on the MCU Pro POWER switch.
  • Launch the software program of choice.
  • Select your software’s console or surface manager set up window.
  • Select the Mackie Control in the MIDI device setup section of your DAW application.
  • Once the Mackie Control is selected within your software’s setup preferences, the unit(s) will be recognized automatically.
  • MCU Pro / MCU XT Pro units may function as a single large console – a “Control Surface Group.”
  • Go to the MCU Pro software section on our website (www.mackie.com/products/mcupro/mcupro_software) for details on using the MCU Pro with your particular application.

To connect one or more MCU XT Pros:

  1. If using the USB method to connect the MCU Pro to a computer, then the MCU Pro has three sets of MIDI IN/OUT connectors for connecting additional MCU XT Pro units. Always connect MIDI OUT from one unit to MIDI IN on the next unit (and MIDI IN to MIDI OUT).
  2. If using the MIDI method to connect the MCU Pro to a computer, then connect the MCU XT Pro to the external USB MIDI interface [the MIDI 3 and MIDI 4 connectors on the MCU Pro are not functional using this method]. Connect the MIDI OUT from the MCU XT Pro to the MIDI IN on the MIDI interface (and MIDI IN to MIDI OUT).

VESA / Omnimount Mounting

  • The MCU Pro and MCU XT Pro have holes in the bottom panel for mounting to a standard VESA wall mount or floating arm mount, using 75 mm or 100 mm mounting patterns. These holes accept M4 (4 mm) screws. The length of the screw will vary depending on the thickness of the mounting plate. The screw length is calculated by determining the thickness of the mounting plate and adding 0.25 inches to that for the threads to engage the pemnut in the bottom of the MCU Pro (see figure below). The MCU Pro weighs 16.8 lb (7.6 kg) and the MCU XT Pro weighs 11.0 lb (5.0 kg), so be sure to select a mounting arm or plate that can support the weight of the unit.
  • Many VESA mounts are designed for video monitors, and the mounting plate is perpendicular to the desktop surface. Since it is unlikely that you will want the MCU Pro mounted perpendicular to the desktop, make sure the VESA mount is flexible enough so it may be properly adjusted for your working space.

notes

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
  3. V-Pot and Channel
  4. V-Pot buttons and power on the MCU Pro or MCU XT Pro.
  5. The faders move up, then down, for calibration. The LCD then displays “Entering fader alignment mode…”
  6. 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.
  7. The LCD will now prompt you to move all faders to the –10 dB mark. When completed, press the Channel 1 REC button.
  8. 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.
