On display on stand 8.571 at IBC 2002 are recently released products from the successful Redbox range, a range of analogue and digital audio interface boxes. These include the RB-DAC1 Digital to Analogue Converter, the RB-DHD6 Digital Headphone Amplifier, the RB-DMA2 Dual Digital Microphone Amplifier and the RB-HD1 Single Stereo Headphone Amplifier.
The RB-DAC1 Digital to Analogue Converter is a 1U rack-mount unit, which 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 level control, allowing full-scale settings selectable from +12dBu, +18dBu or +24dBu.
The RB-DHD6 Digital 6 Way Headphone Distribution Amplifier is a 1U rack-mount which receives a digital input signal, as either AES/EBU or S/PDIF and converts it to 6 individually buffered, jack-plug, headphone outputs, each with their own volume control. The input connectors consist of a single balanced XLR-3 for the AES/EBU input and a single unbalanced phono connector for the S/PDIF input.
The RB-DMA2 Dual Digital Microphone Amplifier consists of two independent low-noise microphone pre-amplifiers for converting microphone level signals to 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 indicator.
The RB-HD1 is a rack-mount stereo headphone amplifier for driving up to two pairs of professional stereo headphones from a single stereo or mono input. One headphone socket is on the front panel with one on the rear. It also has a mono mix input, eg, for mixing in talkback to a main feed, and is VCA remotely controllable.
