The BMG-06D mixer is powered via a DC 5V/1A USB connection. You can use various methods to power the device:

• Connect the provided USB cable to a computer's USB port.
• Connect to a power bank.
• Connect to a standard USB charging head (wall adapter).

4.3 Audio Input Connections

Connect your audio sources to the appropriate input channels:

• Microphones: Use XLR cables for dynamic microphones or condenser microphones. If using condenser microphones, press the +48V button to supply phantom power. Alternatively, 1/4" jack cables can be used for microphones or line-level instruments.
• Line-Level Devices: Connect instruments, keyboards, or other audio players using 1/4" jack cables to channels 1-4, or RCA cables to the IN L/R 5/6 stereo input.
• USB Audio: Connect the mixer to a computer via the USB AUDIO port. This enables the mixer to function as an external sound card.
• Bluetooth: For wireless audio input, activate the BT function and pair with your smartphone or other Bluetooth-enabled device.
• U-Disk: Insert a USB flash drive into the MP3/USB port for direct audio playback.

4.4 Audio Output Connections

• Main Output: Connect your main speakers or amplifier to the BALANCED OUT-L/R (XLR) ports.
• Recording Output: Use the REC/STEREO OUT (RCA) ports to connect to a recording device.
• Headphones: Plug your headphones into the PHONES (3.5mm) jack for real-time monitoring.

5. Operating Instructions

5.1 Power On/Off

Once all connections are made, ensure all volume knobs are at their minimum setting before powering on. Connect the USB power cable. The POWER indicator will light up. To power off, simply disconnect the USB power cable.

5.2 Input Gain Adjustment

For each active input channel, slowly increase the GAIN knob until the SIG indicator lights up consistently. Avoid the PEAK indicator lighting up, as this indicates clipping and distortion. Adjust the GAIN to achieve a strong, clean signal.

5.3 Equalization (EQ)

Use the HIGH and LOW EQ knobs for each channel to adjust the tone of your audio source. Turn clockwise to boost frequencies and counter-clockwise to cut them. This allows you to fine-tune the sound of individual microphones or instruments.

5.4 Effects (DSP)

The BMG-06D features 16 built-in DSP effects. To use them:

1. Turn the DSP PROGRAM knob to select an effect (the number will show on the digital display).
2. Use the DSP+ and DSP- buttons to fine-tune the selected effect parameter.
3. Adjust the EFF knob on each channel to send the desired amount of that channel's signal to the effects processor.

5.5 Volume Control

• Channel Volume: Use the LEVEL faders for each channel to mix the individual audio sources.
• Main Output Volume: Adjust the MAIN OUT knob to control the overall volume of the mixer's main output.
• Headphone Volume: Use the PHONES knob to adjust the volume for your monitoring headphones.

5.6 Bluetooth Connection

To connect a Bluetooth device:

1. Press the BT button on the mixer. The digital display will show "BT" and start flashing, indicating it's in pairing mode.
2. On your smartphone or iPad, go to Bluetooth settings and search for available devices.
3. Select "BMG-06D" (or similar) from the list to pair. Once connected, the "BT" indicator on the mixer will stop flashing.
4. You can now play audio from your device through the mixer.

5.7 USB Playback and Recording

The mixer supports USB flash drive (U-disk) for MP3 playback and recording, as well as functioning as a computer sound card.

9. User Tips

• For optimal sound quality, ensure all cables are securely connected and use balanced cables where possible to minimize noise.
• When using condenser microphones, remember to activate the +48V phantom power for the specific channel. Dynamic microphones do not require phantom power.
• Experiment with the 16 DSP effects to find the perfect sound for your performance or recording. Start with subtle adjustments and gradually increase the effect level.
• Before connecting to a computer, ensure your operating system's audio settings recognize the mixer as the default input/output device for recording or playback.
• If experiencing latency during computer recording, try adjusting the buffer size in your Digital Audio Workstation (DAW) software.
