Driver Installation
Before connecting your UR12 to your computer, it is crucial to install the latest drivers. Do not use any included installation CDs as drivers may be outdated. Always download the most current drivers directly from the official Steinberg website. Follow the on-screen instructions provided by the installer.
Connecting the UR12
Once drivers are installed, connect the UR12 to your computer using the supplied USB cable. The unit is USB-powered when connected to a computer. For iPad connectivity, an Apple iPad Camera Connection Kit or Lightning to USB Camera Adapter is required, along with an external 5V DC power source connected to the micro USB port on the rear panel.

Operating the UR12
Input and Output Connections
Connect your microphone to the XLR input (MIC D-PRE) and your instrument (e.g., guitar) to the HI-Z input. For monitoring, connect your headphones to the PHONES jack and your monitor speakers to the LINE OUTPUT (L/R) RCA jacks on the rear panel.

Gain Control
Use the INPUT 1 GAIN and INPUT 2 GAIN knobs to adjust the input levels for your microphone and instrument, respectively. Ensure the PEAK indicators do not light up consistently, as this indicates clipping and will result in distorted audio. The OUTPUT knob controls the overall volume for both your monitor speakers and headphones.
Direct Monitoring
Press the DIRECT MONITOR button to enable zero-latency monitoring. This allows you to hear your input signal directly through the UR12 without any delay from your computer's software, which is ideal for recording vocals or instruments.
+48V Phantom Power
If you are using a condenser microphone, activate the +48V phantom power switch on the front panel. This supplies the necessary power to the microphone. Ensure dynamic microphones do not require phantom power and should not have this engaged unless specified by the microphone manufacturer.
Software Integration
The UR12 is designed to work seamlessly with digital audio workstations (DAWs). It comes bundled with Cubase AI, a streamlined music production software. Configure your DAW to use the UR12 as its audio input and output device for optimal performance.

Maintenance
To ensure the longevity and optimal performance of your Steinberg UR12, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe down the unit. Avoid abrasive cleaners or solvents that could damage the finish or internal components.
- Storage: Store the unit in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Handling: Handle the unit with care. Avoid dropping it or subjecting it to strong impacts, as this can damage internal circuitry.
- Connections: Always ensure cables are securely connected but do not force them. Disconnect cables by gripping the plug, not the cable itself.
Troubleshooting
If you encounter issues with your UR12, refer to the following common problems and solutions:
| Problem | Solution |
|---|---|
| No sound output. | Check all cable connections (USB, speakers, headphones). Ensure the UR12 is powered on and the OUTPUT knob is turned up. Verify the UR12 is selected as the audio output device in your computer's sound settings and DAW. |
| Input signal is distorted or clipping. | Reduce the INPUT GAIN for the respective channel. Ensure the PEAK indicator is not constantly lit. Check microphone/instrument levels. |
| Microphone not working (condenser mic). | Ensure the +48V phantom power switch is engaged. Check microphone cable and connection. |
| Latency (delay) during recording. | Engage the DIRECT MONITOR button on the UR12. In your DAW, reduce the buffer size in the audio settings. |
| UR12 not recognized by computer. | Ensure the latest drivers are installed correctly. Try a different USB port or cable. Restart your computer and the UR12. |
