4. Nastavení
4.1 Instalace ovladače
For optimal performance and compatibility, especially on Windows systems, it is recommended to install an ASIO driver. While the BMG11S is plug-and-play, a dedicated ASIO driver like ASIO4ALL (freeware) can significantly improve latency and stability with recording software. Download and install the appropriate driver for your operating system from the manufacturer's website or a reputable source.
4.2 Připojení k počítači
- Connect the USB cable from the BMG11S to an available USB port on your computer. The device will be powered via USB.
- Allow your operating system to recognize and install the necessary basic drivers.
4.3 Připojení audio zařízení

- Mikrofon: Connect an XLR microphone to Input 1. If using a condenser microphone, press the 48V button to supply phantom power.
- Instrument (e.g., Guitar): Connect a 1/4" TS cable from your instrument to Input 2. Press the INST button for optimal impedance matching.
- Sluchátka: Connect your headphones to the Headphone Output jack.
- Studiové monitory/reproduktory: Connect the Line Outputs (Right and Left) on the rear panel to your active studio monitors or ampzvedák pomocí 1/4" TRS kabelů.
5. Návod k obsluze
5.1 Adjusting Input Gain
Turn the GAIN knobs (1 and 2) clockwise to increase the input level for the corresponding input. Observe the 'SIG' (Signal) indicator lights. Aim for a strong signal without clipping (distortion). If the 'SIG' light turns red, reduce the gain.
5.2 Activating Phantom Power
If using a condenser microphone, press the 48V button. The red 48V indicator light will illuminate, supplying power to the microphone. Ensure the microphone is connected before activating phantom power.
5.3 Přímé monitorování
Press the DIRECT MONITOR button to enable zero-latency monitoring. This allows you to hear your input signal directly through your headphones and main outputs without any delay from your computer's software. This is crucial for recording to avoid timing issues.
5.4 Adjusting Output Volume
Use the MONITOR knob to control the overall output volume for both your headphones and the line outputs connected to your speakers.
5.5 Recording with Software
Once connected and drivers are installed, open your preferred Digital Audio Workstation (DAW) or recording software (e.g., Audacity, Ableton Live, Cubase). Select the BOMGE BMG11S as your audio input and output device within the software's audio settings. You can then arm tracks for recording and begin capturing audio.

- Store the interface in a cool, dry place when not in use.
7. Řešení problémů
| Problém | Možná příčina | Řešení |
|---|---|---|
| No sound output/input | Incorrect driver, incorrect software settings, loose cables, low gain. | Verify driver installation. Check audio settings in your DAW. Ensure all cables are securely connected. Increase gain levels. Check MONITOR knob. |
| Distortion or clipping | Vstupní zesílení je příliš vysoké. | Reduce the GAIN knob for the affected input until the 'SIG' light no longer turns red. |
| Buzzing or unwanted noise | Ground loop, faulty cable, interference, low-quality power supply (though bus-powered, computer's USB power can vary). | Try a different USB port or computer. Ensure all connections are secure. Use high-quality shielded cables. If using a laptop, try running on battery power to rule out power supply issues. |
| High latency during recording | No ASIO driver (Windows), incorrect buffer size in DAW. | Install an ASIO driver (e.g., ASIO4ALL) on Windows. In your DAW's audio settings, reduce the buffer size. Use the Direct Monitor function. |
| 48V phantom power not working | 48V button not pressed, faulty microphone. | Ensure the 48V button is pressed and its indicator light is on. Test with another condenser microphone if possible. |
