3. Setup
3.1 Power Supply
The BMG-08F-B mixer operates on DC 5V power and supports a 2A power supply. It can be powered by various sources, including a computer USB port, a standard wall charger, a power bank, or even directly from a mobile phone (with appropriate adapter). Ensure the power source provides stable 5V DC at 2A or higher for optimal performance.

3.2 Connecting Audio Inputs
The mixer features 8 channels for various audio inputs. Channels 1-6 are equipped with MIC/LINE inputs, supporting both XLR and 1/4" TRS/TS connectors. Channels 7/8 are stereo line inputs. Each of the first 6 independent channels has a 48V phantom power switch function, which can be activated for condenser microphones. When 48V phantom power is off, these channels can be used for dynamic microphones, guitars, and other instruments.
- Connect microphones to the XLR inputs (Channels 1-6). Activate 48V phantom power for condenser microphones using the individual switches.
- Connect line-level instruments (e.g., keyboards, guitars with preamps) to the 1/4" TRS/TS inputs (Channels 1-6) or stereo line inputs (Channels 7/8).
- Ensure all cables are securely connected before powering on the mixer.
