History of Product Lines
The name Sonifex was synonymous with NAB cartridge machines, and carts, for playing adverts and jingles on the radio. These products had their heyday in the 1980's & early 90's with the analogue micro HS redesigned as the digital Discart floppy disk cart machine.
1989
In 1989 the HY-02 telephone hybrid was developed to enable radio station talk-show callers to be heard more clearly and the HDX2000 hard disk radio automation system was released on Windows 3.11™ in 1994, and developed on Windows 95/98™ until 1998.
1995
The Sovereign analogue radio broadcast mixing console was developed in 1995 together with the DHY-02 DSP based telephone hybrid.
1996
1996 saw the release of the Sentinel 8 channel digital audio logger and the Solutions radio studio furniture, allowing us to sell complete radio broadcast studios.
1997
In 1997 the award winning Courier portable flash-card recorder was announced. With its stylish design, built-in recording, scrub-wheel editing, USB and ISDN live audio, the Courier justified its selection as a Millennium Product by the UK's Design Council. Over 850 Couriers have been sold to the BBC and All India Radio. (Courier shown.)
1999
1999 saw the birth of the Redbox range of Audio interfaces, designed for systems integrators. Between 1999 and 2008 the range has expanded to over 40 different products. The first of the range was the RB-DA6 a 1U rack-mount high performance 6 way stereo distribution amplifier for splitting a source into a number of different outputs.
2001
In 2001, the Net-Log audio logger was born, a 4 channel audio logger which can record weeks of programming on a large internal hard-disk. The unit was designed as dedicated hardware for reliability reasons, i.e. there’s no PC motherboard in this machine. Although PC based systems are great for playback, they generally aren’t robust enough for continuous recording 24/7/365. (RNet-Log shown.)
2004
The D:Scribe transcription system was added in 2004. The S2 hybrid analogue/digital mixer replaced the Sovereign in 2004 and a talkback system was developed in the same year. (Talkback TB-6D shown in new style casing.)
2008
In 2008, two additions were made to the Redbox range of audio interfaces: The RB-ADDA2, a 1U rack-mount which produces an AES/EBU or S/PDIF level digital audio output from a balanced XLR or unbalanced phono stereo audio input; and the RB-SC2, a sample rate converter and a 1U rack-mount which produces AES/EBU, S/PDIF and TOSlink
optical level digital audio outputs from a balanced AES/EBU,
S/PDIF and TOSlink optical level digital audio inputs.
(RB-DC2 shown.)
In 2008, the Reference Monitor range of 1U rack-mount audio monitors was released. Heralding the start of a new direction for Sonifex, these products offer superb quality audio, comprehensive feature-set and exact audio/visual monitoring in a small rack space. Combining the latest DSP technology with outstanding audio enclosure design to produce monitors of the highest standards with exceptional sound quality, a comprehensive feature set and good looks in the rack.
Uniquely an embedded 5 band parametric EQ allows you to configure the monitor for your environment or to suit your listening tastes.
2009
In 2009, three Rack Monitors With Dolby® Decoder,
(RM-4C8-HDE1, RM-4C8-E1X and RM-4C8-E1B) were added to the range of Reference Monitors. The new version of the Reference Monitor can decode a Dolby E or Dolby Digital audio stream allowing you to monitor visually 8 or 5.1 audio channels respectively and to monitor audibly any 2 of those channels. (RM-4C8-HDE1 shown.)
Also, added to the Reference Monitor range in 2009 were the two Confidence Monitors, RM-CA2 (2 LED Meters & 2 Analogue Stereo Inputs) and the RM-CAD8 (2 LED Meters, 2 Analogue & 6 Digital Stereo Inputs). These units use the same outstanding speaker system as the Reference Monitor range,offering a superb sound with a cut-down feature set. The confidence monitors have been designed
to give the best possible performance at a reduced price.
(RM-CAD8 shown.)
In 2009, Sonifex' first Video Redbox was added to the Redbox range of audio interfaces. The RB-VHDA8 is a high performance, reliable eight way digital video distribution amplifier for re-clocking and distributing a 3G, HD (high definition) or SD (standard definition) SDI source to eight outputs. (RB-VHDA8 shown.)
Another addition to the Redbox range in 2009 was the
RB-DSD1
digital silence detection unit. The unit works in a similar way to the Sonifex RB-SD1 analogue silence detection unit, but has AES/EBU, S/PDIF and TOSlink inputs and outputs instead of analogue inputs and output respectively. Designed to switch from one input to another in the event of loss of audio, the unit is ideal at transmitter sites,
or after the master output of a studio, to switch in another
audio source, or simultaneous broadcast, should a master
source fail. (RB-DSD1 shown.)
Yet another innovative design was added to the Sonifex range of products in 2009, the SignalLED Studio Illuminated Signs. The signs are designed for installers and because the sign itself contains the control electronics, and RGB LEDs are used, it can be simply configured onsite.
2010
In 2010, Sonifex further expanded the Reference Monitor range with the introduction of Reference Monitor Meters and Reference Monotor Controllers:
The Reference Monitor Meters are a range of freestanding and 1U rack-mount precision meters offering accurate, high resolution metering of between 1 and 4 stereo audio sources. Each stereo source is auto-switching between either analogue or digital AES/EBU format with sample rates up to 192kHz accepted.
The new Reference Monitor Controllers are a range of 1U rack-mount audio production control units, for providing source selection, volume, DIM and CUT controls for external analogue monitors, together with light controls for the Sonifex SignalLED range of studio signs, or similar.
A innovative addition to the console range is the S1 Digital/Analogue Radio Broadcast Mixer.This is a high performance compact, low cost, fixed format mixing console designed for on-air radio use. It can be fitted flush into a desktop or can be rack-mounted by the addition of optional rack ears.
To the Talkback and Commentary range, Sonifex have introduced the CM-CU21, CM-TBU and the CM-TLL.
The CM-CU21 is a rugged desktop commentator unit for two commentators and a guest providing microphone inputs/outputs, return audio circuit inputs, comprehensive headphone monitoring and talkback facilities. With an extensive feature set the CM-CU21 is perfect for commentary at outside broadcasts and sports events. The CM-TBU Line-Powered Telephone Balance Unit is compatible with all analogue direct exchange lines and provides a 4-wire communications system to interface with the telephone network. The CM-TLL Line Powered Telephone Line Listen Unit provides a low-loss interface to receive audio from a telephone line.
openGear Cards were introduced this year. openGear is an open-architecture rack system developed by Ross Video, a leader in video technologies, to provide a standard rack-based platform on which companies can develop card-based audio & video products. The adoption of openGear based cards by Sonifex allows customers to choose Sonifex cards as part of an overall terminal equipment solution.
Yet more new Redboxes this year including: delays, a voiceover monitor
; tone generators
; a silence switcher
and the introduction of the new Video 3G, HD & SD-SDI models, including embedders/de-embedders
and the Dolby® encoder and decoder
. Still in the familiar Redbox chassis offering rackmounting as standard and a universal AC power supply, these new video Redboxes use latest technology components to offer embedding and de-embedding for analogue and digital audio signals into and out of all 3G, HD and SD-SDI video signals, respectively.
2011
In 2011, Sonifex further expanded the Redbox range with the introduction of the Dolby® E Encoder & Decoder.
The Redbox RB-VHDDD8 is a Dolby® E & Dolby Digital Decoder and De-Embedder. It de-embeds 16 channels of audio within any audio group of an SDI video signal and a further 2 which are sent to the Dolby® Decoder. Up to 10 channels from the decoder or any of the 16 channels from the de-embedder can then be re-embedded onto either of the two SDI outputs and also transmitted on a BNC or D-type situated on the rear panel.
The new Redbox RB-VHEDD8, which is a Dolby® E Encoder and Embedder, encodes 8 channels of audio into two channels of an AES/EBU digital audio stream which is then embedded onto any of the available groups within each of the two video output paths. The encoded Dolby E bitstream is also available via a dedicated output on the rear panel. The audio inputs to the Encoder can be selected to come from the external digital audio inputs or from embedded audio contained in the incoming SDI input. The outputs from the de-embedder can also be re-embedded into the video outputs, along with the encoded inputs.
Also, this year, the Pro Audio Streamers which are a range of three IP to audio and audio to IP streamers which have professional analogue and digital inputs and outputs. They allow audio to be streamed around a building, WAN or LAN using IP audio and CAT5 cabling infrastructure.
There are three products in the range providing encoding/decoding and streaming:
The PS-SEND converts an audio input to an IP stream.
The PS-PLAY reads an IP stream and outputs to balanced and unbalanced audio line levels.
The PS-AMP reads an IP stream and outputs audio to stereo speakers.

2015
2015 introduced a number of new products: the AVN-GMCS IEEE1588 PTP Grandmaster Clock with GPS Receiver
which is a PTPv2 grandmaster clock for use with AoIP applications. IEEE1588-2008 PTPv2 (precision time protocol) is used to synchronise all the nodes within a network. To achieve this one of the nodes must become the master clock and distribute time packets to the others. The AVN-GMCS is designed to perform this role simply and accurately, enabling sub micro second synchronisation between all nodes.
RAVENNA (of which AES67 is a subset) allows for the distribution of audio across a network. For this to be possible, each of the nodes needs to be time synchronised with one another. Ravenna uses PTP time stamping to achieve this, which distributes the network time but also works out the latency involved in the delivery and adjusts the time at each node accordingly. Unit configuration is achieved easily either with the front panel controls or the webserver, including the setup of the PTP profile.
More Redboxes added to the audio interface collection: the 
Redbox RB-MSP6 6 Way Phantom Power Supply
is a 1U rack-mount phantom power supply, designed to be used in conjunction with up to six RB-MS4X3s, providing mains input redundancy to ensure the target microphones remain powered in the event of a single mains failure.
Two mains AC inlets power separate 48V supplies that are diode fed to six locking DC connector outputs. Each output connector is individually protected with a resettable fuse rated at 50mA, so a fault on one output will not affect the others.
And, the RB-FS42 Audio Failover Switcher, 4 Main I/O, 2 Standby I/O
, which is a smaller channel count version of the RB-FS82, offering a lower number of inputs and outputs. It is a more cost effective solution where failover is needed for a smaller number of sources/destinations and supports all of the features of the RB-FS82.
2016
2016 introduced more of the AVN range of products which are IP audio based talkback intercom units with an advanced feature set, allowing them to be used in multiple applications.
