Digital converters launched by Sonifex

Sonifex have released two more digital converters in their Redbox range of audio interfaces - the RB-DAC1 Digital to Analogue Converter and the RB-DMA2 Dual Digital Microphone Amplifier.
Sonifex’s Managing Director, Marcus Brooke, said: "These two new digital products extend our line of digital audio interfaces and provide ideal and cost-effective means of connecting to digital mixing consoles and digital audio routers. With professional connectors, 24/96 processing and simple uncluttered controls, these Redboxes are ideal for fit-and-forget applications where reliability and high performance are pre-requisites."
The RB-DAC1 D/A Converter is a 1U rack-mount that produces a stereo-balanced XLR or unbalanced phono output from an incoming AES/EBU or S/PDIF digital input signal. There is also a headphone output with volume control for monitoring purposes. The analogue outputs have an output control, allowing full-scale settings selectable from +12dBu, +18dBu or +24dBu. There is a button to select either the AES/EBU or S/PDIF input for the D/A converter, which is located on the rear panel.
The RB-DMA2 consists of two independent low-noise microphone pre-amplifiers for converting microphone level signals to a digital AES/EBU or S/PDIF output. The microphone inputs are XLR-3 type and are electronically balanced. The input gain for each input can be adjusted individually by a volume control on the front panel and each has a LED level indicator. For each channel there are independent switches to control a high pass filter with low frequency roll-off at 125Hz, and to provide phantom power at +48V to the connected microphones.
The output bit depth can be selected from 16, 20 or 24 bits. Inputs of a different bit depth to the output are dithered using a pyscho-acoustic noise filter. The content of the channel status bits embedded in the digital audio stream can be defined. For sample rates of 32kHz, 44.1kHz and 48kHz, the status bits can be forced to either professional or consumer mode and will be forced to professional mode for sample rates above 48kHz.
