Sonifex is noting its 10th year of exhibiting at NAB with two additions to its Redbox family of audio interfaces.
The RB-OA3 is a 1 RU, unity gain on-air switcher capable of switching four stereo pairs between three studios. Each studio can control the transmission path; two peripheral paths for equipment, such as a codec or hybrid; and a “last studio to offer” bus, allowing for continuous broadcast from a multi-studio radio network. A Sustain mode also allows for a sustaining system, such as a PC automation system, to control the broadcast.
More switchers can be connected to switch up to six stereo channels among five studios. The switching is achieved using relays, except the “last studio to offer,” which is switched by an analog switch, and the transmission path is switched using latching relays. If there were a power failure to the unit, the transmission path would remain selected.
The RB-SSML1 is 1 RU contribution unit comprising a source selector for compressing or limiting an incoming microphone or line signal, along with selectable level metering and headphone monitor outputs. It provides the facilities often needed in news booths, voice-over booths and at remote studios for recording into a PC.
