Any studio can then accept to resume orthodox broadcasting. This will select the sustaining studio, set as studio three, which will immediately offer control back to all remaining studios. In this case, station control will switch to the automated system by holding the Offer button down for a number of seconds, pre-determined by a calibration routine. The “sustain” mode can be used to control an automated studio, such as an overnight music system. The next scheduled station can then fade in the transmission and accept at the appropriate time meaning the transmission can be continuous. Once offered, the transmission is fed to the other studios via the “last studio to offer” bus. The RB-OA3 also allows for the control of a profanity delay to be shared by all connected studios.Įach studio has the ability to offer the transmission. This could be used for jingles or adverts for example. A transmission mix connection is included to mix audio which is generic to all studios into the transmission path. This means that if there is a power failure to the unit, the transmission path will remain selected.Īll studios are connected using 25 way D-types for electronically balanced audio signals and control is achieved using 15 way D-types, connecting to an external control unit such as the Sonifex S2-MTBS mixer control panel. The transmission path is switched using latching relays. The switching is achieved using relays, except the “last studio to offer” which is switched by an analogue switch.

Can be expanded to switch 6 stereo channels between 5 studios.

Latching relay switching means transmission path remains intact on power-fail.

Continuity mode allows switching to/from a PC playout system.

Has a stereo transformer mix input, e.g.

studio output,codec clean-feeds, telco feeds.

Switches 3 stereo bidirectional channels, e.g.

Controls the offer/accept switching for 3 studios.

Multiple RB-OA3 units can be connected together to switch more studios or more stereo pairs. A “sustain” mode allows for a sustaining system, such as a PC automation system, to control the broadcast. Each studio can control the transmission path together with two peripheral paths for equipment such as a codec or hybrid and there is also a “Last studio to offer” bus, allowing for seamless and continuous broadcast from any multi-studio radio network.

The Sonifex RB-OA3 is a 1U rack-mount, unity gain on-air switcher, capable of switching three stereo pairs between three studios.
