BLUTUBE Series: How To Connect Speakers

Introduction: Connecting your speakers to your Bluetooth receiver is simple, and with the right speaker setup, you can enjoy high-quality sound. In this guide, we'll walk you through the process of connecting your speakers to the receiver, ensuring compatibility with the right impedance for optimal performance.

Step-by-Step Instructions:

1. Understanding Speaker Impedance

• Impedance Matching: On the back of your Bluetooth receiver, you'll find speaker terminals labeled for the left and right channels. Below these terminals, you'll see a sign that reads minimum 4 ohm. This indicates that your receiver is designed for speakers with an impedance of 4 ohms or higher.
• Speaker Setup Options:
  • One 4-ohm speaker per channel: Perfect match with the receiver.
  • One 8-ohm speaker per channel: Works fine.
  • Two 8-ohm speakers per channel: Also works by bringing the impedance down to 4 ohms. Note: Never use two 4-ohm speakers per channel, as it may damage your receiver or speakers.

2. Connecting the Speakers

• Choose Your Speakers: For this setup, we are using Rock Shelf 68 V2 speakers, which are 8 ohms.
• Prepare Speaker Wires: Take your speaker wires and strip the ends to expose the copper for easy connection.
• Connect to the Receiver:
  • Loosen the Terminals: Loosen the left and right speaker terminals on the back of the receiver.
  • Attach the Wires: Insert one end of each speaker wire into the terminals on the receiver, matching red to red and black to black.

3. Connecting the Other End to the Speakers

• Speaker Connections: Plug the other ends of the wires into the terminals on your speakers, ensuring that the red wire goes to the red terminal and the black wire goes to the black terminal.
• Use Banana Adapters (Optional): For easier connections, consider using banana adapters to plug directly into the speaker or receiver terminals.

4. Expanding Your Setup (Optional)

• If you want to expand your setup with additional speakers, you can connect two more 8-ohm speakers per channel. This can be done using parallel wiring.
  • How to Set Up Parallel Wiring:
    • Connect a second set of speaker wires to the first pair of speakers.
    • Attach the other ends to the new set of speakers.
  • For more details, check out our parallel wiring video for a step-by-step guide on expanding your setup.

5. Powering Up

• After all connections are made, turn on your Bluetooth receiver and test the sound to ensure everything is connected properly.

Conclusion: 

By following these steps, you can easily set up your speakers to your Bluetooth receiver for high-quality sound. Whether you're connecting one or more speakers, always ensure the impedance is compatible to avoid damaging your equipment.
