How to Wire and Configure a True Stereo Passive Pair

Every active BT8 master speaker features a built-in 100W RMS Class D amplifier. This allows the active speaker to power itself and an additional passive ceiling speaker simultaneously, creating a wide and immersive true stereo soundstage.

What You Will Need

  • Active BT8 master speaker
  • Compatible passive ceiling speaker
  • Speaker cable (5m cable included)
  • Wire cutters/strippers (if required)

Step 1 – Prepare the Speaker Cable

If you are not using the supplied pre-stripped cable:

  1. Take the included speaker cable.
  2. Strip approximately 10mm of insulation from each wire end using wire cutters or wire strippers.
  3. Ensure the copper strands are neatly twisted together.

Step 2 – Connect the Cable to the Active Speaker

Locate the gold-plated spring-loaded Speaker Output terminals on the outer chassis of the active BT8 speaker.

These terminals are labelled:

  • Red (+)
  • Black (-)

To connect:

  1. Press down the terminal tab.
  2. Insert the bare copper wire fully into the terminal opening.
  3. Release the tab to clamp the wire securely in place.

Step 3 – Connect the Passive Speaker

Run the speaker cable through the ceiling to the passive speaker location.

Insert the opposite cable ends into the matching terminals on the passive speaker:

  • Red to Red (+)
  • Black to Black (-)

Ensure polarity is matched correctly for proper stereo performance.

Step 4 – Enable Stereo Mode

On the side of the active BT8 speaker chassis, locate the:

Stereo / Mono Selector Switch

Move the switch to:

Stereo Mode

This configures the system so:

  • The active speaker plays the Left channel
  • The passive speaker plays the Right channel

creating a true stereo listening experience.

Why Use True Stereo?

A stereo pair provides:

  • Wider sound dispersion
  • Better channel separation
  • Improved music detail
  • More immersive listening
  • Balanced room coverage

This setup is ideal for:

  • Living rooms
  • Kitchens
  • Bedrooms
  • Open-plan spaces
  • Commercial environments

Installation Tips

  • Keep speaker cable runs tidy and secure within the ceiling void.
  • Ensure all wiring is firmly connected before powering on.
  • Avoid reversing polarity, as this can affect sound quality and stereo imaging.
