New Sonifex Reference Monitors
RM-2S4 Reference Monitor, 2 LED meters, 4 stereo channel audio inputs.
RM-2S10 Reference Monitor, 2 LED meters, 10 stereo channel audio inputs.
RM-4C8 Reference Monitor, 4 LED meters, 8 channel inputs, dual selectors.
RM-2S4
Each one is a 1U rack-mount unit offering quality loudspeaker monitoring and accurate, high-resolution metering of up to four or ten stereo audio sources (more with the addition of an optional expansion card). Sources may be in any mixture of analogue and AES/EBU digital formats, with sample rates up to 192kHz accepted and a 5 band parametric EQ can be used to tailor the unit for the room it is mounted in.
Sources are selected via a front panel rotary encoder, with clear LED indication of the current selection. A pair of line-level audio outputs, configurable as analogue or AES/EBU digital, follow the selected source at either a fixed level or one mirroring the loudspeaker volume.
An optional addition to each model are two HD video input expansion cards, allowing multiple AES groups of PCM or Dolby audio, embedded within an HD-SDI or SD-SDI signal, to be de-embedded and monitored.
RB-PD2 Stereo Profanity Delay
The RB-PD2 is a stereo audio profanity delay used for live broadcast programs to prevent unwanted or obscene material from being transmitted. It features an automatic audio stretch algorithm that allows between 2 and 55 (*) seconds of delay to be built up live whilst “on air”, whilst maintaining the correct pitch. The delay can also be acquired whilst playing a pre-selected audio file on a CompactFlash™ memory card. When the program is complete, the audio stretch algorithm seamlessly reduces the delay to zero.
The RB-PD2 has both balanced analogue and AES/EBU digital audio inputs and outputs on 3 pin XLR connectors and provides sample rates up to 48kHz at 24 bit. It can act as acombined A/D and D/A unit meaning that analogue inputs can be output as AES/EBU or vice-versa.
The delay can be initiated by pressing the BUILD DELAY button on the front panel. A front panel display shows the amount of delay being built-up, up to the amount initially selected.
There are several ways to make sure that any unwanted material is removed from the audio at the outputs. A COUGH function, activated from a dedicated front panel button, allows locally generated sounds being presented at the inputs, such as the presenter coughing or equipment switching noises, to be discarded.
The DUMP function, which is also activated from a front panel button, has 2 different modes. The first DUMP mode removes a section of audio that has already been buffered, by a pre-selected amount. The second DUMP mode plays a pre-selected audio file on the Compact Flash™ memory card. When the file has finished playing, the delay is then equal to the duration of the file. The DUMP button can be used multiple times to use up the built-up delay and once used, the unit automatically starts to rebuildthe original delay time.
As a last resort, all the buffered audio can be discarded by pressing and holding the DUMP button which activates the DROP function.
At the end of a radio show when you want to broadcast live, the delay can be ramped down by pressing the front panel EXIT DELAY button.
A dedicated record mode allows audio presented at either the analogue or digital inputs to be recorded to a linear WAV file on a Compact Flash™ memory card. Additionally, the card format used is PC readable, allowing pre-recorded linear WAV files to be transferred easily from a PC or other such device.
Sonifex RB-OA3 Studio On-Air Switcher
The RB-OA3 is a 1U rack-mount, unity gain on-air switcher, capable of switching three stereo pairs between three studios. 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. A "sustain" mode allows for a sustaining system, such as a PC automation system, to control the broadcast. Multiple RB-OA3 units can be connected together to switch more studios or more stereo pairs.
The switching is achieved using relays, except the "last studio to offer" which is switched by an analogue switch. The transmission path is switched using latching relays. This means that if there is a power failure to the unit, the transmission path will remain selected.
All 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. A transmission mix connection is included to mix audio which is generic to all studios into the transmission path. This could be used for jingles or adverts for example. The RB-OA3 also allows for the control of a profanity delay to be shared by all connected studios.
Each studio has the ability to offer the transmission. Once offered, the transmission is fed to the other studios via the "last studio to offer" bus. The next scheduled station can then fade in the transmission and accept at the appropriate time meaning the transmission can be continuous
The "sustain" mode can be used to control an automated studio, such as an overnight music system. 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. This will select the sustaining studio, set as studio three, which will immediately offer control back to all remaining studios. Any studio can then accept to resume orthodox broadcasting.
The RB-OA3 can be expanded to switch between up to 5 studios or up to 6 stereo pairs by connecting a multiple of units together via RJ45 serial connections. With the addition of a single unit, expansion in "studio" mode allows for 2 additional studios to take control of the transmission path and additional equipment. If the expansion is made in "bus" mode, then three additional stereo channels can be added. 4 x RB-OA3 units can be connected together to switch 6 stereo pairs between up to 5 studios.
The modes are configured by dip switch configurations, on the rear of each unit. Two dip switches control the unit ID and there are two switches which decide between "studio" and "bus" modes. A master unit, defined by a preset ID, conducts all communication between all units.

Staiton Master
Talkback refers to the standard method of communication between broadcast studios. Each studio has either a desktop, a rack-mount, or mixer-mounted intercom, usually containing a row of switch buttons. Each switch button connects to another studio when pressed, and routes the presenter audio to it.
There are 4 products in the Sonifex Talkback Intercom range : - TB-6D - 6 Way Talkback Intercom, desktop free standing
- TB-6R - 6 Way Talkback Intercom, 19" rack mounted
- TB-SD - Station Master Talkback Intercom, desktop free standing
- TB-SR - Station Master Talkback Intercom, 19" rack mounted
The TB-6D and TB-6R are general talkback interfaces which can be connected together to form a talkback system. The TB-SD and TB-SR are talkback units which only operate when connected to the Sonifex Station Master studio switcher.
TB-SD & TB-SR - Station Master Talkback Intercom units are used for interfacing with the Sonifex Station Master studio switcher and are similar to the 6 way talkback intercoms, except that the talkback routing and switching (DC signalling) is handled by the Station Master.
Talkback For Up To 5 Locations
Radio Studio Application Using TB-SD & TB-SR Using the Station Master as the core of a complete studio air-switching, distribution and talkback system, up to 4 studios can be connected using the TB-SD and TB-SR. A typical application would be to distribute talkback and audio feeds around a small radio station, as in this diagram.
The TB-SD and TB-SR intercoms are connected to the Station Master in a star pattern, with the Station Master as the central hub and unbalanced point-to-point links from it to each location. This setup could also be used for controlling on-air switching and for distribution of the external inputs to the other locations.
TB-6D & TB-6R 6 Way Talkback Intercoms The TB-6D and TB-6R are used for general talkback between studios and use DC signalling, also known as ground lifting or ground signalling, to communicate with each other. These units can be installed in various locations throughout a studio complex and linked to one another, with each unit being able to talkback to up to 6 others connected together. Most other talkback systems in general operation also use DC signalling, so you should be able to add these units into an existing installation.
Desktop Or Rackmount
Talkback For Up To 7 locations
Press & Release, Press & Hold Operation
Onboard Electret Mic or External Mic
Monitoring External Inputs
Built-in Loudspeaker & Headphones
Radio Studio Application Using TB-6D & TB-6R A typical application would be to distribute talkback and audio feeds around a radio or TV studio complex, as in this diagram.
The TB-6D and TB-6R units are daisy-chained together from location to location and the radio station output from an off-air receiver is distributed on input EXT 1 of each unit. The EXT 2 input could be used in the news or sales area for monitoring local sources such as a PC audio output. Linking the studios in this way allows all locations to talk to each other together with the ability to monitor 2 external feeds, with independent control of monitor muting and headphone/speaker levels.
