Short answer
Mix Out: Yes — on models equipped with a Mix Out jack, all inputs, including Bluetooth audio, are mixed together on the XLR output.
Thru: No — Thru outputs do not forward Bluetooth audio; they only pass the speaker’s analog input signals.
Why?
Bluetooth → internal DSP → Mix Out: On many Mackie models, the Bluetooth receiver feeds the speaker’s internal mixer/DSP. The Mix Out takes that mixed signal and can send it to another device or speaker — so Bluetooth audio ends up on Mix Out.
Thru = straight hardware pass-through: The Thru jack is a direct analog duplication of the physical input jack signals (used for daisy-chaining analog sources). Because it bypasses the internal mixed DSP where Bluetooth is routed, Bluetooth audio is not present on Thru.

Setup Suggestions
| Connection Type | Speaker → Speaker | Speaker → Subwoofer | Bluetooth Linking Notes |
|---|---|---|---|
| Mix Out Models | Bluetooth passes through Mix-Out to the next speaker | Bluetooth passes to the sub via Mix Out | If the speakers support Bluetooth Linking, use that instead of cables whenever possible (more convenient + wireless stereo). |
| Thru Models | Bluetooth does not pass through Thru (analog inputs only) | Bluetooth does not reach the sub via Thru | Bluetooth Linking is still supported between speakers if the model includes that feature — but subwoofers cannot Bluetooth Link. |
Systems with Subwoofers
If your setup includes a subwoofer (or multiple subs), the best solution is:
Use a Bluetooth-equipped mixer → feed the entire PA (mains + subs) via cables.
This ensures Bluetooth audio reaches every speaker and subwoofer in the system!
