The front panel of the MR18 provides access to the primary input channels and essential status indicators:

• Input Channels 1-16: Combo XLR/TRS jacks for microphone and line-level inputs. These inputs feature MIDAS PRO preamplifiers.
• Input Channels 17-18: TRS jacks for line-level inputs.
• USB Port: Type-A USB port for connecting a USB drive for recording and playback.
• MIDI In/Out: 5-pin DIN connectors for MIDI control.
• Status LEDs: Indicators for power, Wi-Fi connection, and signal presence.

4.2 Rear Panel

The rear panel houses the main power input, network connections, and main outputs:

• Power Input: IEC connector for the included power supply.
• Ethernet Port: RJ45 connector for wired network connection to a router or computer.
• Remote Control Switch: Selects between Access Point, Wi-Fi Client, or Ethernet modes for network connectivity.
• Main Outputs (L/R): XLR connectors for the stereo main mix output.
• Aux Outputs 1-6: XLR connectors for auxiliary mixes (monitor sends, effects sends).
• Headphone Output: TRS jack with dedicated level control.

5. Setup

5.1 Power Connection

1. Connect the provided power supply to the MR18's power input on the rear panel.
2. Plug the power supply into a suitable AC outlet.
3. Press the power switch to turn on the unit. The Power LED on the front panel will illuminate.

5.2 Network Connection

The MR18 offers three modes for network connectivity, selected via the "Remote Control" switch on the rear panel:

• Access Point (AP): The MR18 creates its own Wi-Fi network. This is ideal for direct control from a tablet or laptop without an external router.
• Wi-Fi Client: The MR18 connects to an existing Wi-Fi network. This allows control from devices already on that network and can provide internet access to the mixer (for firmware updates, etc.).
• Ethernet: Connect the MR18 directly to a computer or an external router via an Ethernet cable for a stable wired connection.

For detailed instructions on configuring each network mode, refer to the full software manual available on the MIDAS website.

5.3 Tablet/Computer Connection

Download and install the appropriate control application for your device:

• iPad: M AIR App from the Apple App Store.
• Android: M AIR App from the Google Play Store.
• PC/Mac/Linux: M AIR EDIT Software from the MIDAS website.

Once installed, launch the application and connect to your MR18 via the configured network connection.

6. Operating the MR18

The MR18 is controlled entirely through its dedicated software application. This section provides a general overview of key operational aspects.

6.1 Basic Operation

• Channel Strips: Each input channel in the software provides controls for gain, phantom power, EQ, dynamics (gate/compressor), and routing.
• Mixing: Adjust faders for individual channels and master outputs. Create auxiliary mixes for monitors or effects sends.
• Effects: The MR18 includes a virtual effects rack with various reverbs, delays, and modulation effects.

6.2 Input/Output Configuration

The software allows flexible routing of inputs to channels and outputs. You can assign physical inputs to any processing channel and route any mix bus or channel to the physical outputs.

6.3 Recording via USB

The MR18 features an 18x18 channel bidirectional USB2.0 audio interface. This allows you to record all 18 input channels directly to a connected computer (DAW software required) or play back 18 channels from your computer through the mixer.

6.4 Dugan-style Auto-Mixing

The MR18 incorporates Dugan-style auto-mixing, which automatically manages microphone gain sharing. This feature is particularly useful in multi-microphone setups (e.g., panel discussions, conferences) to reduce feedback and improve clarity by automatically attenuating unused microphones and boosting active ones.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the mixer. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure that the ventilation openings are not blocked to prevent overheating.
• Storage: When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures.
• Firmware Updates: Regularly check the MIDAS website for firmware updates to ensure optimal performance and access to new features.
