Dante Networked Audio

NBB-04R Networked Audio Receiver / NBB-04T NetworkedAudio Transmitter

  • .Dante-enabled networked Audio Receiver (NBB-04R) and Transmitter (NBB-04T)
  • .Streaming audio in robust standard Ethernet cable (a.k.a., Digital Snake)
  • .Easily organize and expand network topology with Ethernet switches
  • .Uncompressed 24-bit PCM coding with sample rate up to 96KHz
  • .Two RJ-45 ports make Daisy-chain cascading feasible
  • .Powered by either PoE or 48V adapter
  • .Gain or Attenuate control for each channel
  • .Phantom power engagement control per channel (NBB-04R)
  • .A signal clip indicator for all inputs (NBB-04R)
  • .XLR Combo sockets for both XLR and phone plugging (NBB-04R)
  • .Routing and other configuration are set with Dante Controller software


The NBB-04R receives 4 channels of analog audio and converts them into Dante networked audio stream which in turn can be received by other Dante-enabled devices such as digital audio console or DAW; While the NBB-04T, in contrast, transmits 4 channels of analog audio converted from Dante networked audio stream which is distributed from other Dante-enabled devices. 

Both NBB-04R and NBB-04T are equipped with two RJ-45 Ethernet ports so that several NBB- 04R/NBB-04T can be cascaded, i.e. in daisy-chaining, in the same network link. Also both NBB- 04R and NBB-04T can be powered by either PoE from Ethernet switch or 48V from external power adapter.


The NBB-04R and NBB-04T adopt Audinate Dante networking technology for audio transceiving, and are very network friendly with unlimited flexibility in topology of deployment. They support up to Layer 3 of IEEE 802.3 network standard, enabling you to organize your audio network with the on the-shelf Ethernet switches or to immediately transport streaming audio by taking advantage of your existing installed network facility with no hassle. Even better, every NBB-04R/NBB-04T comes with two Ethernet ports which allow you to physically cascade several NBB-04Rs/NBB-04Ts in the same network link. Accompanying with Ethernet switches, this capability helps NBB-04R/NBB-04T gaining flexibility and expanding territory in device deployment in audio networking.

Audio routing among NBB-04Rs/NBB-04Ts and all the other Dante-enabled devices is configured via computer with dedicated Dante Controller software which is available free from Audinate website. With Dante Virtual Soundcard software, you are even able to have your DAW software direct record/play multitrack streaming audio from/to NBB-04R/NBB-04T.

The audio input/output interfaces of NBB-04R/NBB-04T are fully met the requirement of professional audio industrial. Audio is encoded/decoded with the latest and uncompressed 24-bit PCM encoder/decoder with sample rate in 44.1KHz, 48KHz, or 96KHz. The NBB-04T outputs are peculiarly buffered with amplifiers of high-rail-voltage which can drive the lines up to 24dBu. Besides the high-level of drive capability, the output of NBB-04T can also be attenuated to meet the narrower reception range of inputs of some semi-professional devices. All inputs of NBB-04R accept signal of level from mic to line with individual gain and phantom power control. The NBB-04R is also equipped with a clip indicator for all the inputs to warn audio technician any signal overload on inputs.

The NBB-04R/NBB-04T is assembled in a sturdy metal chassis with four bumpers on the edges. This we think is very important for you to damp the NBB-04R/NBB-04T from accidental smash during field installation.
