Sonifex Announce New Products at IBC 2010

At this year's IBC2010 exhibition on stand number 8.E61, Sonifex are announcing a number of new audio and video products designed for broadcast use. The new video products are Dolby Digital versions of the 3G/HD/SD-SDI Embedder & De-embedder for use with Dolby E and Dolby Digital audio in all digital video signals up to 3G.

There are 3 new audio distribution products, two for analogue audio and one for digital, all of which use RJ45 connectors to distribute the audio: The RB-DA6R 6 way stereo distribution amplifier is a 1U rack-mount high performance amplifier for splitting a source into a number of different outputs. The amplifier provides multiple balanced audio outputs using RJ45 connectors wired to the StudioHub+ standard. By using RJ45 outputs, it allows simpler CAT5 cabling to used to connect the amplifier to other products.

The RB-DDA22 is a digital audio distribution amplifier with multiple inputs and multiple outputs designed to accept one of 5 different digital inputs, amplify it and output this to 22 digital audio outputs in 5 different audio formats, accepting signals with sample rates in the range 32kHz to 192kHz. There are 5 inputs, one each of balanced AES/EBU on an XLR socket, unbalanced AES/EBU on BNC, balanced AES/EBU on an RJ45 socket, unbalanced S/PDIF on a phono socket and a TOSlink optical connection. An illuminated front panel input select push button is used to choose one of the 5 inputs, or to select the Auto Mode. In Auto Mode the unit interrogates each of the inputs in turn until it finds a lock. There are loss of lock and signal presence indicators for each channel.

The CM-TBU and CM-TLL are small line powered telephone balance and telephone line listen units acting as small, rugged and affordable 2-wire to 4-wire converters for IFB applications: 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 high degree of separation between send and receive signals makes it suitable for use in telephone IFB (interrupted foldback) applications and the high drive capacity at the 4-wire output enables a presenter's earpiece to be connected directly to the unit without an external amplifier.

This extremely compact unit is powered from the telephone line and provides an interface to a 4-wire circuit with separate level control of send and receive signals. Optimum rejection of the input signal on the 4-wire output is by using manual adjustment which can be used to compensate for local line variations or to adapt to the telephone systems of other countries, where line characteristics may differ.

The CM-TLL line powered telephone line listen unit provides a low-loss interface to receive audio from a telephone line. The line-powered unit is compatible with all analogue direct exchange lines and includes an LED indication of incoming calls. The unit is intended to be used with an earpiece amplifier to receive an audio feed by telephone from a studio. The line and telephone set are connected to the unit via the RJ11 connectors in order to make an outgoing call. A telephone may not be required if calls are only incoming, because telephone line ringing is indicated by a flashing LED built into the unit. In either case, the 'LINE CONNECT' switch is pressed to make the line connection.

The Phone In 6 is a 6 line telephone switching system designed for radio talkshows. The Phone In 6 consists of a desktop Remote Control Panel for call control, and a rackmount Base Console which contains all of the audio and telephony connections, including two superb quality digital telephone hybrids. Connected via ethernet, the units make up a simple, easy to use talkshow system.The Base Console can be loaded with 2, 4, or 6 phone line modules, where each module can have 2 PSTN (normal telephone) lines or 1 ISDN BRI lin (2 x B channels).

The Phone In 6 uses an echo-cancellation DSP algorithm and impedance matching to give around 70dB cancellation, which provides excellent separation of caller & line send audio and elimination of feedback, distortion & echo on the incoming calls. This is close to being the best performance possible on a telephone line & uses the same enhanced echo cancellation algorithms as used on the Sonifex DHY-03, the best performing telephone hybrid in the world.
