No, the QSC K10.2 has no Bluetooth of its own. Best path: a Bluetooth receiver with XLR output into Input A or Input B, set to Line in the menu. QSC notes the inputs provide no phantom power, so there is nothing to fry, and the gain knob per input keeps levels honest.

Where to connect
Combo XLR inputs (Input A, Input B)
RecommendedBoth take balanced XLR or 1/4 inch plugs, and each carries its own gain knob and signal LED. Leave Input A on the Line menu setting, since QSC cautions the MIC setting adds gain and distortion for line sources. A receiver with XLR output plugs straight in.
Input C 3.5 mm TRS
Good alternativeThe stereo mini input exists for small sources, and it sums into the same DSP and mix path. Handy for a test feed, though a full-size receiver on the combo jacks holds cables more securely on a moving floor.
Speaker-level sources
Not recommendedThe three inputs expect mic, instrument or line level per the manual. Feeding amplifier outputs into them hammers the input stage. The XLR loop-thru jacks, not the inputs, are the intended way to share a signal between K10.2s.
Set up in three steps
- Pick the input
Input A for the XLR receiver, checked to Line in the menu. Input B also takes line sources through its menu, so Input A is the simpler home for a wireless feed.
- Connect and power
XLR from the receiver, then the locking IEC mains. Both a front and a rear power LED confirm the rocker switch.
- Level check
Start the Input A gain knob low, play from the phone, then raise until the green SIG LED pulses with the music. The limiter LED, if it lights up, means back off.
Quirks and notes
- No phantom power, on purpose (verified): the manual states the input does not provide phantom power. Condenser mics need their own juice, and Bluetooth receivers have one less thing to worry about.
- Menu-driven gain staging (verified): the MIC and Line selection for Input A lives in the LCD menu, and QSC warns output level increases significantly when MIC is selected. A receiver belongs on Line, full stop.
- Two flavors of output (verified): the two XLR loop-thrus pass inputs onward for daisy-chaining, while the mix output carries the post-gain sum of all three inputs, so a second speaker across the room can mirror the blend.
- DSP presets live behind two buttons (verified): contours and delay settings sit behind the LCD and selection buttons, letting one cabinet flip between main and monitor duty without a laptop.
What you need
- Bluetooth receiver with XLR output, aptX HD preferred for source quality
- One XLR cable, receiver to speaker
- Mains outlet within cable reach, the speaker takes 100-240 V
- USB power for the receiver, a phone charger is fine
FAQ
No. The K.2 series user manual describes no wireless input of any kind. The K10.2 joins Bluetooth through an external receiver plugged into its combo or 3.5 mm inputs.
Plug a Bluetooth receiver with XLR output into Input A or Input B with a standard XLR cable, leave the input set to Line in the menu, set the gain knob low, then raise it as playback starts. No internal modification is needed.
Input A is a combo XLR and 1/4 inch jack switchable between MIC and Line in the menu, Input B is a combo jack switchable between HI-Z and Line in the menu, and Input C is a 3.5 mm TRS stereo jack. Each input has its own gain knob and signal LED.
Yes. Two XLR loop-thru outputs pass the input signals to daisy-chain another loudspeaker, and a separate XLR mix output carries the post-gain mix of all three inputs.
blafili XLR Bluetooth Audio Receiver
XLR output for balanced inputs, aptX HD, USB powered with a 16-hour battery. Plugs into the K10.2 combo inputs directly.
