No, the Alto TS312 has no Bluetooth of its own. Best path: a Bluetooth receiver with XLR output into Input 1, which takes mic or line level, with the volume knob low and the Contour switch engaged for music. The XLR link output then feeds a second cabinet without splitters.

Where to connect
Combo XLR/TRS inputs (Input 1)
RecommendedThe guide rates Input 1 for dynamic microphones over XLR or TRS and, elsewhere, both inputs for line-level DJ mixer and controller outputs, so a Bluetooth receiver with XLR output sits squarely in range. One cable, one volume knob per input.
Link output to the second cabinet
For the pairThe XLR link output connects to another loudspeaker's input per the guide, and the hookup examples show DJ mixers feeding one speaker each or a shared mix downstream. A pair covers a small hall from one wireless feed.
Speaker-level sources
Not supportedThe two combo inputs take mic or line level per the guide, and its hookup diagrams keep amplifier outputs out of them. Passive speakers belong on a separate amplifier's outputs, not here.
Set up in three steps
- Pick the input
Input 1 for the receiver. Engage Contour for recorded music, or leave it out for a flatter voice on spoken-word duty.
- Connect and power
XLR from the receiver, then the switchable mains supply. The front and rear power LEDs both confirm the state, handy when the cabinet faces away from you.
- Level check
Start each volume knob low and raise with music playing until the clip limiter LED stays dark on peaks. The guide advises not turning the knobs past the 0 dB mark for hot mixer feeds.
Quirks and notes
- One knob per input (verified): each combo channel carries its own volume control, so a wired mic and the wireless feed level independently before the fixed crossover point.
- Contour is a recorded-music lift (verified): the plus 3 dB low and high boost flatters playback, and the guide explicitly recommends the flatter disengaged setting for live performance.
- Ground lift for venue hum (verified): the rear ground-lift switch addresses the loop hum that appears when the cabinet and a mixer sit on different mains circuits.
- Direct guitar accepted on Input 2 (verified): the guide's hookup example runs an active-pickup guitar into Input 2 with a TS or TRS cable, so a two-source set can run the wireless feed and a guitar across the two combo channels.
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 on the switchable supply
- USB power for the receiver, a phone charger is fine
FAQ
No. The TS3 series user guide describes no wireless input of any kind. The TS312 joins Bluetooth through an external receiver plugged into its two combo inputs.
Plug a Bluetooth receiver with XLR output into Input 1 with a standard cable, start the volume knob low, and raise it as playback runs. The guide rates Input 1 for both mic and line level.
It engages a plus 3 dB boost on the low and high frequencies for recorded music, and disengages to a flatter response suited for live performance, per the guide.
Yes. The XLR link output connects to the input of another loudspeaker, per the guide, so a pair mirrors the same feed.
blafili XLR Bluetooth Audio Receiver
XLR output for balanced inputs, aptX HD, USB powered with a 16-hour battery. Plugs into the TS312 combo inputs directly.
