Introduction
The RME ADI-2 FS is a compact and highly flexible 2-channel Hi-End AD/DA-converter designed for professional audio applications. It provides first-class analog-to-digital and digital-to-analog conversion at sample rates up to 192 kHz, supporting SPDIF, AES, and ADAT formats. This device features an analog bypass mode, accommodating levels up to +22dBu, and facilitates conversion between balanced and unbalanced analog signals. Its versatile connectivity ensures broad compatibility, making it a universal solution for various audio setups.
Setup
This section details the initial steps for setting up your RME ADI-2 FS converter.
1. Unpacking and Inspection
Carefully remove the ADI-2 FS from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Ensure all included accessories, such as the power supply, are present.
2. Power Connection
Connect the provided power supply to the POWER input on the rear panel of the ADI-2 FS. The power plug features a locking mechanism; insert it at the correct angle and twist to secure it firmly in place. This prevents accidental disconnection. Connect the power supply to a suitable electrical outlet.

4. Analog Output Connections
Connect your monitoring system (e.g., studio monitors) to the ANALOG OUTPUTS on the rear panel. These consist of two balanced XLR outputs for Left (L) and Right (R) channels, and two unbalanced RCA outputs. Choose the appropriate connection type for your equipment.
5. Digital I/O Connections
The ADI-2 FS offers various digital input/output options:
- AES-3 / SPDIF: Use the coaxial RCA connectors for AES/EBU (with adapter) or SPDIF signals.
- ADAT (Ch. 1/2): Use the optical TOSLINK connectors for ADAT signals.
Connect your digital audio devices accordingly to the DIGITAL I/O section on the rear panel.
Operating Instructions
This section covers the primary functions and controls of the RME ADI-2 FS.
1. Front Panel Overview

- ANALOG INPUT (DIG) Level Meters: Displays input levels for Left (L) and Right (R) channels. The OVR (Overload) indicator illuminates when the signal is too high.
- LEVEL Knob (Analog Input): Adjusts the input gain for analog signals.
- CLOCK Section: Indicators for sample rates (32, 44.1, 48, QS, DS) and clock source (COAX, OPT).
- DIG IN / DIG OUT Buttons: Selects digital input and output formats (ADAT, PRO, CON).
- ANALOG OUTPUT (D/A MONITOR) Level Meters: Displays output levels.
- LEVEL Knob (Analog Output): Adjusts the output level for analog signals.
- VOL Knob (Headphones): Controls the volume for the headphone output.
- PHONES Jack: Connect your headphones here.
2. Input and Output Level Settings
The ADI-2 FS features three distinct settings for input and output levels (+4 dBu, +13 dBu, +19 dBu) to ensure optimal compatibility with various analog equipment. Adjust these settings as needed to match the nominal operating levels of your connected devices and prevent clipping or low signal-to-noise ratios.
3. Digital Connectivity and Format Conversion
The coaxial RCA SPDIF I/O offers a switchable Channel Status, allowing it to be fully AES/EBU compatible (a cable adapter may be required). When the input selection is set to DIG, the device functions as a digital format converter, enabling simultaneous monitoring of the converted signal.
4. Headphone Output
The High Power² headphone circuitry provides robust performance with up to 0.7 watts per channel, a 0.1 ohm output impedance, and a maximum output level of +19 dBu. This ensures compatibility with a wide range of headphones. Adjust the VOL knob to set your desired listening level.
5. Clocking
The ADI-2 FS is equipped with custom-built digital clocking for excellent performance across all clock modes. Ensure your clock source is correctly selected (e.g., internal, COAX, OPT) and that the sample rate matches your session settings (32 kHz, 44.1 kHz, 48 kHz, or higher via QS/DS modes).
Maintenance
Proper maintenance ensures the longevity and optimal performance of your RME ADI-2 FS.
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Avoid abrasive cleaners or solvents, which can damage the finish.
- Ventilation: Ensure the unit has adequate ventilation to prevent overheating. Do not block the ventilation grilles.
- Environment: Operate the ADI-2 FS in a clean, dry environment, away from extreme temperatures, humidity, and direct sunlight.
- Cable Connections: Periodically check all cable connections for security and integrity. Loose connections can lead to signal loss or noise.
