Front Panel Illumination

The M-32 AD Pro II-D features a unique concept for its front panel illumination, which consists of:

  • A ring illumination around the standby switch that shows the overall state of the device.

  • 32 channel labels with integrated backlight metering (peak or RMS).

  • A display with standby screen that shows categorized warnings.

All elements have been designed to give the user thorough status feedback even from a distance. The channel backlight metering can be configured to hold over events for 5 s or infinitely. Each of the three sections can be individually switched off (dark mode).

Dark Mode

Each of the three front panel illumination sections can be switched off if they are not required.

Visual Feedback Tab in State section
To turn off illumination on the device:

  1. Open the visual feedback tab in the STATE section.

  2. Change any of the following:

    1. Power to Toggle off Off to turn off the standby switch ring illumination.

    2. Meters to Off or Dim to turn off or dim channel label backlight.

    3. Display to Toggle off Off to turn off the display.

When any item is turned off, a notification (orange) is shown in the STATE section.
To turn panel illumination back on:

  1. Open the same menu and set the corresponding switches to Toggle on to On.

To turn the front panel lighting on temporarily, just rotate or push the encoder. The panel will turn back off after five seconds.
To turn off illumination on the web remote:

  1. Connect to the device remotely (see: Remote Control Overview).

Changing the Meters to Peak or RMS Mode

Depending on the application, instantaneous peak level metering or a slower, averaged RMS metering may be preferred.

To change the metering mode on the device:

  1. Open the visual feedback tab in the STATE section.

    Visual Feedback Tab

  2. Push the encoder on the current "Metering:" value to activate selection.

  3. Change the value to "Peak" or "RMS".

To change the metering mode on the web remote:

  1. Connect to the device remotely (see: Remote Control Overview).

  2. Locate the visual feedback tab in the STATE section.

  3. Push the Peak or RMS button in the global metering settings.

This is a global setting which affects both the front panel level meters and the remote control interface.

Persistent Clipping Notifications and Peak Hold

The maximum level of signals can be saved and shown on the front panel and web remote. Clipping is detected when three consecutive samples reach digital full scale (0 dBFS). The duration of how long the maximum level or clipping is shown can be manually changed to either five seconds or until they are manually reset.

This is a global setting which affects both the remote control and the device.

Over indication

On the device, an over notification is signaled as a fast flashing (red) of the label backlight.
To switch over notifications on or off:

  1. Open the visual feedback tab in the STATE section

    Visual Feedback Tab in State section

  2. Change OVR Hold to either:

    • 5s to notify for five seconds

    • On to notify until manually reset

    • Off to deactivate over notifications.

To reset infinite full scale notifications:

  1. Open the visual feedback tab in the STATE section.

  2. Activate Reset.

The remote shows an over notification above the level meter, both in miniature port level meters and the larger level meters when a port is open.

To switch persistant over notifications on or off:

  1. Locate the Visual Settings Tab.

  2. Change Peak + OVR Hold to either

    • 5s to notify for five seconds

    • On to notify until manually reset

    • Off to deactivate over notifications

To reset over notifications:

  1. Within the Visual Settings Tab, use the ⟲ reset button.

Metering of Digital Signals

The incoming and outgoing digital signals can be visually inspected to ensure that signals are properly received and routed. All levelmeters adhere to IEC 60268-18 scaling and feature RMS levels with a separate peak indicator. Peak and over hold times can be configured in Front Panel Illumination.

To show the digital level meters on the device display:

  1. Open the input section (see: Use of the Display and Encoder).

On the web remote, each input and output port has integrated level meters.
