3. Setup Guide

3.1. System Requirements

• Compatible Operating Systems: Linux, Windows, macOS.
• USB 2.0 or higher port.
• Digital Audio Workstation (DAW) software.

3.2. Driver Installation

1. Visit the official RME website (www.rme-audio.de/downloads.html) to download the latest drivers for your operating system.
2. Follow the on-screen instructions to install the drivers. Restart your computer if prompted.

3.3. Hardware Connection

1. Connect the RME Digiface AES to your computer using a USB cable. The device is bus-powered, so no external power supply is typically needed.
2. Connect your microphones or line-level instruments to the XLR/TRS combo inputs on the device.
3. Connect your headphones to the dedicated headphone output for monitoring.
4. Connect your studio monitors to the balanced analog outputs (L/R) using appropriate cables.
5. For digital connections, use AES/EBU, S/PDIF, or ADAT ports as required by your setup.

4. Operating Instructions

4.1. Powering On/Off

The RME Digiface AES powers on automatically when connected to a powered USB port on your computer. To power off, simply disconnect the USB cable or shut down your computer.

4.2. Input Gain Adjustment

Adjust the input gain for each microphone or instrument connected to ensure optimal signal levels without clipping. Use the physical gain controls on the device or the software control panel (TotalMix FX) to set appropriate levels. Aim for signal levels that are strong but do not consistently peak into the red.

4.3. Phantom Power (48V)

For condenser microphones, activate 48V phantom power. This can typically be toggled via a button on the device or within the TotalMix FX software. Ensure phantom power is only enabled for microphones that require it.

Use the dedicated headphone output for direct monitoring of your input signals and playback. Adjust the headphone volume using the corresponding knob. TotalMix FX allows for complex monitoring mixes, enabling you to create custom sub-mixes for performers or different monitoring scenarios.

4.5. Using with DAW Software

1. Open your Digital Audio Workstation (DAW) software.
2. Navigate to your DAW's audio settings or preferences.
3. Select the RME Digiface AES as your primary audio input and output device.
4. Configure your input and output channels within your DAW to match your hardware connections.
5. Utilize TotalMix FX for advanced routing, mixing, and DSP effects as needed for your recording or playback session.

5. Maintenance
