The NBB-020P transmits stereo audio to Dante network while NBB-020A receives stereo audio from Dante network. Both NBB-020P and NBB-020A are direct powered by PoE which means you don't need to find AC outlets for device deployment.

The NBB-020P accepts wide range of analog audio signal from MIC to LINE level and it also can deliver 48V phantom power to condenser microphones connected. The NBB-020A has high analog output capability which fully meets the industrial standard up to 24dBu.


The NBB-020P/NBB-020A adopts Audinate Dante networking technology for audio transceiving, and is very network friendly with unlimited flexibility in topology of deployment. It supports 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. Accompanied by Ethernet switches, you can flexibly expand territory of device deployment in audio networking with NBB-020P/NBB-020A.

Audio routing among each NBB-020P/NBB-020A 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 stereo streaming audio from NBB-020P or to NBB-020A.

The analog audio input/output interfaces of NBB-020P/NBB-020A fully meet the requirements of the professional audio industry. Audio is encoded(NBB-
020P) / decoded(NBB-020A) with the latest and uncompressed 24-bit PCM encoder(NBB- 020P) / decoder(NBB-020A) with sample rate in 44.1KHz, 48KHz, or 96KHz. The NBB-020A 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-020A can also be attenuated to meet the narrower reception range of inputs of some semiprofessional devices. Both inputs of NBB-020P accept signal of level from mic to line with individual gain and phantom power control. The NBB-020P is also equipped with a clip indicator for both the inputs to warn audio technicians of any signal overload on inputs.

The NBB-020P/NBB-020A is assembled in a sturdy metal chassis with elegant style of aluminum front panel. They are very slim in height which allows them to insert in a 1U space in a regular 19" mount-rack.
