Nixer PD Dante

The Unika NBB-0202 is a 2-channel, bidirectional analogue I/O interface for Dante AoIP networks. It is PoE-enabled, making it ideal for rapid deployment in live situations. It is a great solution for a commentary/presenter position on OBs, as a musician’s personal I/O node as a combined DI box and monitor feed, or anywhere that stereo I/O access to a Dante network is needed.

  • Can be defined as clock master (by Dante Controller)
  • Compatible with Dante Controller, Dante Virtual Soundcard and Dante Domain Manager
  • Sync and System LEDs indicate unit’s network status
  • High quality analogue signal paths
  • AC adaptor and 19” rackmounting kit supplied

The Unika NBB-1616 is a bidirectional, 16-channel analogue Dante interface in a 3U rack unit; it may be expanded to 32-channels by the addition of a NBB-1616e expansion unit. The Unika NBB-04R and NBB-04T are POE-powered “throw-down” units providing either four analogue inputs (R version) or four analogue outputs (T version), and may be thought of as Dante DI boxes.

Description

The Unika NBB-0202 is a bidirectional, 2-channel analogue break-in/break-out box for use in Dante AoIP networks. It will operate via PoE (from a suitably-enabled Ethernet switch), which makes it ideal for rapid deployment as a local network node in live sound and OB situations. It is constructed in an attractively designed, sturdy steel chassis with a very simple set of front panel controls, making it an excellent “desk top” choice for a presenter’s or commentator’s position at sporting events or similar OB situations. Being bidirectional, it can also serve as a musicians personal interface to a PA system, providing both microphone or line inputs to the mixing console and return line feeds for a personal monitoring system.

An AC adaptor (PSU) is supplied with each unit for installations where PoE is not available; a 19” rack kit is also supplied with each unit

The units are fully compatible with all current Audinate software, including Dante Controller, Dante Domain Manager and Dante Virtual Soundcard. Dante Controller is the standard system configuration application: Mac and Windows versions are available as freeware from Audinate’s website. It supports automatic device discovery, free routing of Dante channels anywhere on the network, as well as allowing clock master selection, latency allocation, backup/restore of configurations and numerous other housekeeping functions.

The NBB-0202 has two balanced analogue mic/line inputs using “Combo” type connectors, which can accept either standard XLR plugs or ¼” TRS jack plugs. Both have a switched gain control, with 12 dB increments from 0 to 60 dB. 48 V phantom power, with LED indication, is individually selectable on both. Two Clip LEDs are fitted, which illuminate if the input level is too high. The two line outputs are balanced, on XLR connectors, calibrated for +24 dBu = 0 dBFS. Each output has a switched rotary attenuator providing 6 dB, 12 dB or 20 dB of level reduction, thus making the unit compliant with the UK broadcast standard of +18 dBu = 0 dBFS.

Two Ethernet ports provide connection to the Dante network, and for daisy-chaining to further units. One port is enabled for PoE (Power over Ethernet), and the units will use this as their DC power source if the network connection is to an Ethernet switch supporting PoE. (Daisy-chained units must either be powered by a separate PoE-enabled Ethernet connection, or with the AC adaptor supplied.) Two front panel bicolour LEDs indicate sync clock and unit statuses.

The NBB-0202 may be configured by Dante Controller to use any two input and two output Dante channels. Supported sample rates are 44.1, 48, and 96 kHz, with bit depths of 24 or 16: these settings are also configured from Dante Controller.

Cable runs of up to 100 m between connected Dante devices are possible using Cat 5e cable (screened Cat 5e is recommended for electrically noisy environments): longer cable runs may be achieved by the use of gigabit Ethernet switches with fibre interfaces, single-mode fibre allows units to be located several kilometres apart.
