Yes, a Yamaha PX5 Bluetooth connection is a two-cable job. Each channel takes a balanced XLR or 1/4 inch TRS feed, and the input sensitivity ships at the +4 dBu setting, so a Bluetooth receiver with XLR output plugs straight in. The amplifier's onboard DSP handles voicing, and the manual's Basic mode needs no menu digging for this connection.

Where to connect
Balanced XLR inputs
RecommendedTwo XLR-3-31 jacks take the receiver feed directly. Input sensitivity ships at the +4 dBu setting, a close match for a consumer-level wireless source, and the spec table's 34.3 dB gain figure at that setting covers full output. Changing it is an Advanced-mode menu task, per the owner's manual.
¼" TRS inputs
Good alternativeEach channel also carries a balanced TRS jack at the same impedance, so a receiver with a 1/4 inch balanced output works without adapters. Unbalanced TS plugs land fine too at the 10 kilohm unbalanced rating.
Speaker-level sources
Not supportedEvery input expects mic or line level per the specifications. The Speakon, binding post and phone outputs are for loudspeakers only; nothing in the documentation offers a speaker-level input path.
Set up in three steps
- Check the sensitivity setting once
The amp ships with input sensitivity at +4 dBu, a good match for a wireless receiver, and the setting is a whole-unit menu item in Advanced mode rather than a per-channel knob. Leave it alone unless levels run wrong.
- Connect and power
XLR from the receiver, speakers on the Speakon jacks, then AC. The PX5 idles at 55 watts, so leaving it powered between sets costs little.
- Level check
Raise the volume controls with music playing. The output meter tracks level and signal, and the D-CONTOUR FOH/MAIN preset keeps long sessions honest if the cabinet lineup changes.
Quirks and notes
- A DSP brain behind the panel (verified): input summing, D-CONTOUR FOH/MAIN and MONITOR voicing, delay up to 74 msec and a 6-band PEQ speaker processor live on board, with eight user presets and factory presets for Yamaha passive speakers.
- Power Boost doubles down (verified): the bridge-style mode pushes 1400 watts into one 4 ohm cabinet at the 120 V and 220-240 V ratings, wired per the manual before power-up. Stereo ratings stay the everyday numbers.
- Light 2U chassis (verified): 6.9 kg in a standard rack frame with front-to-back depth under 400 mm, so a receiver and this amp share a shallow effects rack without complaint.
- USB is for settings, not audio (verified): the USB port saves amp settings and takes firmware per the specifications; music still enters through the XLR and TRS jacks only.
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 wired for Speakon or binding posts
- 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 or binding post outputs, then raise the volume controls after playback starts. Both channels need a feed for stereo, and each channel's XLR and TRS jacks are alternative connections for the same input.
Input impedance is 20 kilohms balanced and 10 kilohms unbalanced, with a maximum input of +24 dBu. Input sensitivity is configurable in the manual's Advanced mode among four gain settings (32 dB, 26 dB, +4 dBu and +14 dBu per the specifications), and the +4 dBu default pairs well with consumer-level wireless sources.
No. The owner's manual, reference manual and technical specifications describe no wireless input of any kind. Bluetooth arrives with the receiver you connect to its XLR or TRS inputs.
It bridges the amp into a single channel for one cabinet. At the 120 V and 220-240 V ratings the specifications list 1400 watts into 4 ohms or 800 watts into 8 ohms in Power Boost mode, on top of the stereo ratings of 500 watts per channel at 8 ohms and 800 watts per channel at 4 ohms.
