Yes, a Yamaha P2500S Bluetooth connection is a two-cable job. Each channel takes a balanced XLR-3-31 or 1/4 inch TRS feed at 30 kilohms, so a Bluetooth receiver with XLR output plugs straight in. Rated output is 275 watts per channel into 8 ohms at 1 kHz, with a subwoofer filter onboard for split rigs.

Where to connect
Balanced XLR-3-31 inputs
RecommendedEach channel carries an XLR-3-31 jack alongside a balanced TRS phone jack, and the manual describes both input types as standard equipment. A Bluetooth receiver with XLR output plugs straight in, one cable per side.
¼" TRS inputs
Good alternativeThe balanced phone jacks mirror the XLRs at the same 30 kilohm balanced impedance. At 32 dB of gain and a +3.6 dBu sensitivity, consumer-level wireless sources drive the amp with headroom to spare.
Speaker-level sources
Not supportedThe inputs expect mic or line level per the manual. The Speakon, binding post and phone jacks are outputs for loudspeakers; nothing in the documentation offers a speaker-level input path.
Set up in three steps
- Choose the mode
The rear MODE switch selects stereo, parallel or bridged duty, and the two FILTER switches plus their corner knobs shape a subwoofer or low-cut role per channel.
- Connect and power
XLR from the receiver, speakers on the Speakon jacks or posts, then AC. The volume knobs step through 31 positions from minus infinity to 0 dB.
- Level check
Raise both volumes with music playing. The green signal LED lights past 2 Vrms per channel, which makes a handy sanity check while the wireless feed settles.
Quirks and notes
- Subwoofer filtering onboard (verified): two FILTER switches with 25 to 150 Hz corner knobs run a subwoofer or low-cut role per channel, so one chassis can feed a passive sub and the tops with the right roll-offs.
- YS Processing switch (verified): Yamaha's processing voicing has its own rear-panel switch, leaving the wireless chain untouched either way.
- Three operating modes (verified): stereo keeps channels independent, parallel sends channel A's input to both outputs, and bridge combines them for a single cabinet, wired per the manual.
- Quiet by design (verified): variable-speed low-noise fans and a 100 dB signal-to-noise rating suit the sanctuary-and-auditorium duty this amp usually sees.
What you need
- Bluetooth receiver with XLR output, aptX HD preferred for source quality
- One XLR cable per amp channel, or TRS cables for the balanced jacks
- Speaker cable for the Speakon or binding post outputs
- USB power for the receiver, a phone charger is fine
FAQ
Plug the XLR output of a Bluetooth receiver into the amp inputs with standard XLR cables, run speaker cable from the Speakon, binding post or phone outputs, then raise the two 31-step volume controls after playback starts.
Input sensitivity is +3.6 dBu for rated output at 8 ohms, with 32 dB of voltage gain and 30 kilohm balanced or 15 kilohm unbalanced input impedance. Consumer-level wireless sources land comfortably below the ceiling.
No. The owner's manual describes no wireless input of any kind. Bluetooth arrives with the receiver you connect to its XLR or TRS inputs.
The rear panel carries YS Processing alongside FILTER switches for subwoofer or low-cut duty with a 25 to 150 Hz corner, letting one amp feed a passive sub and tops with the right filtering per channel.
