NAB Sneak Peek: Sonifex Debuts Silence Detector
     

Broadcast equipment maker Sonifex will bring to the 2014 NAB Show something not usually seen these days, a new silence detector.

The RB-SD1IP silence detector is an upgrade of the current RB-SD1 but has added Ethernet and USB capabilities.

Ethernet connectivity allows set up and control via a browser-based GUI together with a real-time viewing of signal levels and alarm statuses. SNMP V1 is implemented so that the unit can be controlled by existing network management systems and GPI pins enable the generation of SNMP traps on behalf of other, non-networked, hardware. A front-panel USB port can hold a prerecorded message that the unit can play out in the event that both main and auxiliary signals fall silent.

Also new to the Sonifex booth will be the RB-MS4X3 quad three-way passive microphone splitter, one of three new passive splitters. The company says that each of the four banks is designed to split a single microphone or line source to up to three destinations, using Neutrik XLR connectors. Cable connections are located on the rear panel, with recessed controls and indicators available to the user on the front, allowing easy access to setup parameters. Sonifex says that it uses high-quality audio transformers that are capable of accepting input levels of up to +18 dBu, making the splitter useful in both microphone and line-level splitting applications. A 30 dB pad can be applied to the input, allowing a line-level signal to be interfaced into a microphone input with suitable levels and the correct termination.

Another new splitter is the RB-DDA6A3, a digital distribution amplifier for distributing AES3id digital audio, repeating both the audio data and the status information of the input while re-normalizing to standard digital audio levels. It has a single BNC AES3id audio input which is distributed to six BNC AES3id audio outputs.
