Yes, a Yamaha DBR12 Bluetooth connection takes one RCA pair. Channel 2 carries RCA pin jacks beside its combo jack, so a Bluetooth receiver with RCA output plugs straight in with the level knob at center. The link output then feeds a second DBR as a passthrough or a mixed send.

Where to connect
RCA pins on INPUT 2
RecommendedThe manual gives channel 2 an RCA pair alongside its combo jack, and rates the input to +24 dBu maximum. A Bluetooth receiver with RCA output plugs straight in; the combo jack stays free for a wired mic on the same channel, with the manual noting the two mix to mono at a fixed balance.
Combo jack on INPUT 1
Good alternativeA receiver with XLR output drives INPUT 1 directly. The level knob's center detent marks +10 dBu for line sources or -22 dBu for mics, so a wireless feed lands comfortably left of the clip point.
Speaker-level sources
Not recommendedBoth inputs expect mic or line level per the manual. The XLR output on the rear panel sends signal onward to another DBR, not the reverse path; amplifier outputs belong on passive speakers only.
Set up in three steps
- Pick the input
RCA pins on INPUT 2 for the receiver, with the level knob at center. Set the D-CONTOUR switch to FOH/MAIN for mains or MONITOR for a floor wedge.
- Connect and power
XLR or RCA from the receiver, then mains. The DBR12 draws about 74 watts, so a household circuit carries a pair easily.
- Level check
Raise the level knob with music playing and listen for the limiter. The link switch decides whether the second cabinet hears channel 1 alone or the 1+2 mix.
Quirks and notes
- RCA shares its channel (verified): INPUT 2's RCA pins and combo jack mix to mono at a fixed balance per the manual, so run the wireless feed and a wired mic with that blend in mind.
- Two flavors of link output (verified): the rear XLR sends a passthrough of channel 1 or the mixed 1+2 signal, covering both mirror-a-pair and mono-fill setups.
- Monitor preset on a switch (verified): D-CONTOUR's MONITOR mode tunes the cabinet for floor duty, and the yellow indicator confirms which preset is active.
- Featherweight for its class (verified): at 15.8 kg with side handles and an f35 pole socket, the DBR12 moves between rooms without a cart, and M8 points on the bottom plus one at the rear cover suspended installs.
What you need
- Bluetooth receiver with RCA output, LDAC or aptX HD preferred
- RCA cable of a meter or two, receiver to speaker
- Mains outlet within cable reach, the speaker draws 74 W
- USB power for the receiver, a phone charger is fine
FAQ
Plug a Bluetooth receiver with RCA output into the RCA pin jacks of INPUT 2, keep the level knob at its center detent, and raise it as playback starts. The feed arrives at line level, rated for a maximum input of +24 dBu.
INPUT 1 is a single combo jack accepting XLR or phone plugs, and INPUT 2 adds two RCA pin jacks beside its combo jack. Input 1 takes line at +10 dBu or mic at -22 dBu sensitivity with the level centered.
No. The owner's manual describes no wireless input of any kind. Bluetooth arrives with the receiver you connect to its RCA or combo inputs.
Yes. The XLR output sends either a direct copy of channel 1 or a mix of channels 1 and 2, per the link switch, so a second cabinet can mirror the first without a splitter.
blafili B3 Bluetooth Music Receiver
RCA + XLR + optical out, LDAC and aptX HD, OLED status display. Plugs into the DBR12 RCA pins without adapters.
