Maintenance

- Cleaning: Use a soft, dry cloth to wipe down the exterior of the device. Avoid using abrasive cleaners or solvents, as they may damage the finish.
- Storage: When not in use, store the Amber i1 in a cool, dry place away from direct sunlight, excessive heat, or moisture.
- Cable Care: Always handle cables by the connectors, not the wires, to prevent damage. Avoid kinking or sharply bending cables.
- Ventilation: Ensure the device has adequate ventilation to prevent overheating. Do not block any ventilation openings.
Troubleshooting
If you encounter issues with your ESI Amber i1, try the following troubleshooting steps:
- No Power/Connection: Ensure the USB-C cable is securely connected to both the Amber i1 and your computer. Try a different USB port or cable.
- No Sound Output: Check the Master volume knob and headphone gain. Verify that your speakers/headphones are connected correctly and powered on. Ensure the correct output device is selected in your computer's sound settings and DAW.
- No Input Signal: Verify that your microphone/instrument is properly connected. Check the input gain knobs (Mic Gain, Hi-Z Gain). Ensure the correct input source is selected using the 'Input' button. If using a condenser microphone, ensure +48V phantom power is activated.
- Latency Issues: Ensure you have installed the latest ESI drivers for your operating system. Adjust buffer size settings in your DAW (lower buffer size reduces latency but requires more CPU).
- Driver Recognition Issues: If the device is not recognized after driver installation, try restarting your computer. Ensure no other audio drivers are conflicting.
