- Water and Moisture: Do not expose this apparatus to rain or moisture. Do not use this apparatus near water.
- Heat: Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Servicing: Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
3. Setup
3.1 Unpacking and Inspection
Carefully unpack the M32C and inspect it for any signs of damage that may have occurred during transit. Retain the original packaging for future shipping or storage.
3.2 Physical Installation
The M32C is designed for standard 19-inch rack mounting and occupies 1U of rack space. Secure the unit using appropriate rack screws. Ensure sufficient airflow around the unit for proper cooling.
3.3 Connections
Refer to the rear panel diagram below for connection points.
Figure 3.1: Midas M32C Rear Panel. This image displays the rear panel of the M32C, showing all input and output ports including AC input, expansion slot, USB, Ethernet, MIDI, ULTRANET, AES50, and monitor/talkback connections.
- AC INPUT: Connect the supplied AC power cable here.
- EXPANSION SLOT: For optional expansion cards (e.g., DN32-USB for USB audio interface).
- USB 2.0: For firmware updates and data transfer.
- REMOTE ETHERNET: Connect to a network router or computer for remote control via M32-EDIT software or M32-MIX app.
- MIDI IN/OUT: For connecting external MIDI devices.
- ULTRANET PERSONAL MONITORING: Connect to Behringer P16-M personal mixers for distributed monitoring.
- AES50 PORT A/B: Connect to Midas digital stage boxes (e.g., DL16, DL32) for expanded input/output capabilities. These ports support up to 96 inputs and 96 outputs.
- MONITOR OUTPUT (BAL/UNBAL): Analog outputs for local monitoring.
- TALKBACK INPUT (MIC/TRIM): Analog input for a talkback microphone.
3.4 Initial Power-Up
After all connections are made, press the power button on the front panel. The unit will initiate its startup sequence. Observe the front panel display for status indicators.
4. Operating the M32C
4.1 Front Panel Controls
Figure 4.1: Midas M32C Front Panel. This image shows a direct front view of the M32C, detailing the USB/DATA port, the central display, AES50 port indicators, the main rotary encoder, and the power button.
- USB/DATA Port: Used for connecting USB storage devices for firmware updates or scene/preset management.
- Display: Provides essential status information, including AES50 connection status and basic system parameters.
- AES50 PORT A/B Indicators: LEDs indicate active AES50 connections.
- Rotary Encoder: Used for navigating menus and adjusting parameters displayed on the front panel.
- Power Button: Turns the unit on or off.
4.2 Remote Control
The M32C is primarily controlled via external software. Connect the unit to a network using the REMOTE ETHERNET port. You can then use:
- M32-EDIT Software: A comprehensive application for Windows, macOS, and Linux, offering full control over all mixer functions.
- M32-MIX App: Mobile applications for iOS and Android devices, providing remote control capabilities for mixing on the go.
4.3 AES50 Networking
The AES50 ports are crucial for expanding the M32C's capabilities. They allow connection to digital stage boxes, providing remote microphone preamplifiers and analog outputs, effectively extending the mixer's I/O count to up to 96 inputs and 96 outputs.
4.4 Mix Buses and DSP
The M32C features 25 time-aligned and phase-coherent mix buses, providing flexible routing and processing options for monitors, effects sends, and matrix mixes. The 40-bit floating point digital signal processing ensures high-fidelity audio and extensive dynamic range.
5. Maintenance
5.1 Cleaning
To maintain the appearance and functionality of your M32C, regularly clean the exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure ventilation openings are free from dust and debris.
5.2 Firmware Updates
Periodically check the Midas website for firmware updates. Keeping your M32C's firmware current ensures optimal performance, access to new features, and bug fixes. Firmware updates are typically performed via the front panel USB port using a USB flash drive.
6. Troubleshooting
If you encounter issues with your M32C, consult the following common troubleshooting steps:
- No Power:
- Verify the AC power cable is securely connected to both the unit and a working power outlet.
- Check the power switch position.
- No Audio Input/Output:
- Ensure AES50 connections to stage boxes are secure and active (check AES50 indicators).
- Verify input and output routing within the M32-EDIT software or M32-MIX app.
- Check gain staging for all channels and buses.
- Remote Control Connection Issues:
- Confirm the Ethernet cable is properly connected to the REMOTE ETHERNET port and your network.
- Check network settings (IP address, subnet mask) on both the M32C and your control device.
- Ensure firewall settings on your computer or mobile device are not blocking the M32-EDIT/M32-MIX application.
- Unit Freezes or Behaves Erratically:
- Perform a power cycle (turn off, wait 10 seconds, then turn on).
- Consider performing a factory reset (refer to the Midas website or full software manual for instructions).
- Ensure firmware is up to date.
