- LINE IN (6.35mm): For general audio input.
3. Bluetooth Pairing
- Ensure the amplifier is powered on.
- Activate Bluetooth on your mobile device (smartphone, tablet, etc.).
- Search for available Bluetooth devices and select "BP60D" to pair.
- Once paired, you can stream audio wirelessly from your device to the amplifier.
Operating Instructions
1. Basic Controls
- Volume Knobs: Each input channel (Microphone 1, Microphone 2, Guitar 1/2, B.T./MP3) has its own volume control. Adjust these to balance the levels of your connected devices.
- Main Volume: The "MAIN VOLUME" knob controls the overall output level of the amplifier.
- EQ Controls: Independent EQ controls (Low, Mid, High) are available for adjusting the tone of your sound. Experiment to find your desired sound.
- Effects (Reverb, Chorus, Delay): Adjust the dedicated knobs for Reverb, Chorus, and Delay to add spatial and modulation effects to your sound.
2. Using Phantom Power
For condenser microphones, activate the +48V phantom power on MIC1 by pressing the corresponding switch. Ensure your condenser microphone is connected before activating phantom power to prevent damage.
3. Recording and Live Broadcasting
- USB Recording: Connect a USB drive to the USB port to record your performance directly.
- Live Broadcast: Connect your mobile phone to the amplifier using an appropriate cable (e.g., 6.35mm Line Input or Record Out to phone's audio input) for live broadcasting on platforms like Facebook or YouTube. Note: The standard BP60D version does not include a dedicated OTG live recording interface.
4. Headphone Monitoring
Connect headphones to the "PHONES" output jack for private listening or monitoring your mix without affecting the main output. This is useful for practice or fine-tuning your sound.
