Sonifex Showing Redbox Audio Interfaces at AES San Francisco 2004

Sonifex is showing its complete range of Redbox audio interfaces at the AES San Francisco 2004 exhibition on stand 816 of its US distributor Independent Audio. The Redbox range of audio interfaces continues to expand with the addition of some new audio distribution products.
The RB-DDA6W 6 way word-clock distribution amplifier has been added to the range of distribution products. The unit's primary application is to distribute a master BNC TTL world clock source to up to 6 BNC word-clock pieces of equipment that need to be synchronised from the master.
Two line isolation units have been added to the matching amplifier range; the RB-PLI6 6 way passive line isolation unit and the RB-LI2 stereo line isolation units. These are useful where audio is required to be driven over a relatively long length of cable. By isolating the signal using transformers, ground loop currents which can be present in non-isolated signals, are eradicated completely.
The RB-DSS10, 10 way digital source select unit is a 24 bit 96kHz capable 1U rack-mount which produces an AES/EBU and S/PDIF level digital audio output from 10 selectable AES/EBU or S/PDIF digital input signals. There are 10 illuminated front panel push buttons, which select and indicate the current channel selection, as well as remote selection. As well as routing the selected audio signal, the unit will also route a remote signal inputs through the remote connector to the selected input source, for starting external audio equipment such as a CD player. There is a front panel headphone socket with volume control for monitoring.
The RB-SS10 10 way analogue source select/mixer unit is similar to the RB-DSS10, but has analogue audio inputs and outputs and can also mix the inputs to the output as well as route them.
The RB-LC3 3 way power/light controller has been designed specifically for radio and TV studio light signalling, so that "on-air" and "mic/live" signs can be powered and controlled remotely from a mixing console.
