Yes, a Behringer NX3000D Bluetooth connection is a two-cable job. The two combo jacks take balanced feeds at 20 kilohms, rated sensitivity is 0.775 V for full power into 4 ohms, and the onboard DSP adds delay, crossover and 19 user presets. Both channels need a feed for stereo, one XLR cable per side from the receiver.

Where to connect
Combo inputs (channels A and B)
RecommendedTwo balanced combo jacks at 20 kilohms take the receiver feed directly, one per side for stereo. At the 0.775 V rated sensitivity, a consumer-level wireless source has volume in reserve.
USB for setup, not for music
Control onlyThe rear USB type B connector drives the DSP section remotely, per the specifications. Presets, delay and crossover travel over that cable; program audio still enters through the combo jacks.
Speaker-level sources
Not supportedThe two combo jacks are the only signal inputs per the specifications. The locking speaker connectors feed loudspeakers; nothing in the documentation offers a speaker-level input path.
Set up in three steps
- Pick a preset
The amber LCD and rotary encoder reach 20 presets, 19 of them user-definable, so the DSP can match the cabinets before the first cable goes in.
- Connect and power
XLR from the receiver, speakers on the locking connectors, then AC. The thermal and DC protection plus on/off muting guard the turn-on sequence.
- Level check
Raise the two gain controls with music playing. The signal LEDs step through -40, -6 and -3 dB, and the zero attack limiter catches peaks before the drivers see them.
Quirks and notes
- DSP before weight (verified): the D in NX3000D brings a delay of up to 300 milliseconds per channel and crossover filters up to 48 dB per octave, which lets one amp anchor both a sub and tops without outboard gear.
- 5.9 kg? No, 3.6 kg (verified): the NX3000D column of the specifications lists 3.6 kg (7.9 lbs) in a 94 × 483 × 231 mm frame, drawing 350 W at one-eighth rated power into 2 ohms, so a shallow rack with a receiver inside stays genuinely portable.
- Locking outputs only (verified): the two speaker connectors are locking-style professional connectors, per the specifications, so keep Speakon-style cables in the case.
- USB is control, not audio (verified): the rear type B port exists for remote control of the DSP section; music enters through the combo jacks alone.
What you need
- Bluetooth receiver with XLR output, aptX HD preferred for source quality
- One XLR cable per amp channel, receiver to amp
- Speakon-style speaker cable for the locking outputs
- USB power for the receiver, a phone charger is fine
FAQ
Plug the XLR output of a Bluetooth receiver into the two combo jacks with standard cables, wire speakers to the locking connectors, then raise the front gain controls after playback starts.
The specifications list 0.775 V (0 dBu) input sensitivity for rated power into 4 ohms, with 10 kilohm unbalanced and 20 kilohm balanced input impedance.
No. The quick start guide describes no wireless input of any kind. Bluetooth arrives with the receiver you connect to its combo inputs.
The amber backlit LCD and rotary encoder reach 20 presets with 19 user-definable, per-channel delay from 0 to 300 milliseconds, crossover filters in three types up to 48 dB per octave, and a zero attack limiter per channel.
