How to Enable the 3.5mm Hardwired Audio Line-In

If you want to connect a direct, lag-free audio source such as a turntable, CD player, PC, or non-wireless television, you can use the built-in 3.5mm analog auxiliary input on the speaker.

Step 1 – Locate the 3.5mm Input

Find the 3.5mm Jack Line-In port located on the rim of the active BT8 speaker chassis.

Step 2 – Connect Your Audio Device

Using a standard 3.5mm auxiliary male-to-male audio cable, connect:

• Your TV, media player, turntable preamp, or audio source output
  to
• The speaker’s 3.5mm Line-In port

Step 3 – Disconnect Bluetooth Devices

The Line-In input is auto-detecting, however:

• Active Bluetooth connections take priority over the wired input.
• Ensure all connected Bluetooth devices are disconnected or Bluetooth is turned off on nearby devices.

Step 4 – Manually Change Playback Mode (If Required)

If the speaker does not automatically switch to the Line-In source:

1. Remove the magnetic grille.
2. Locate the Connection Button.
3. Short-press the button to cycle through playback modes until the wired input is selected.

Step 5 – Confirm Line-In Mode

When the speaker is successfully using the 3.5mm Line-In input:

• The internal LED indicator will flash Green.

This confirms the speaker is playing audio from the wired source.

Ideal Uses for the 3.5mm Line-In

The wired input is ideal for:

• TVs requiring low-latency audio
• Turntables with preamps
• CD players
• PCs and laptops
• Media streamers
• Audio devices without Bluetooth

Using the wired input provides a stable, direct audio connection with minimal delay.
