The success of the Redboxes, a range of analogue and digital audio interface boxes, is set to continue. The range of interfaces has expanded to over 23 different products and includes a number of different pieces of equipment useful for monitoring and distributing audio feeds. Existing products include a 6 way headphone distribution amplifier, the RB-HD6 and a 6 way stereo distribution amplifier, the RB-DA6. New additions to this line, being launched at NAB 2002 are the RB-HD1 Single Stereo Headphone Amplifier, and the RB-DHD6 Digital 6 Way Headphone Distribution Amplifier.
The RB-HD1 is a 1U rack-mount stereo headphone amplifier for driving up to two pairs of professional stereo headphones from a single stereo, or mono, input. It’s main purpose is for installations where the unit needs to be remotely controlled. One headphone output is front mounted, with one on the rear panel together with the main stereo input on XLR-3 connectors. The output volume for the headphones can be controlled either by a potentiometer on the front panel or a VCA signal supplied externally via the remote connector.
A mono input can be mixed into the main headphone feed, for example, for mixing in talkback to the headphones. This has an input level control via a recessed adjustable potentiometer. The mono mix input can also be remotely controlled.
The RB-DHD6 digital 6 way headphone distribution amplifier is a 1U rack-mount which has both AES/EBU and S/PDIF digital inputs and produces 6 separately buffered, jack-plug headphone outputs, each with their own volume control. It’s been designed to provide distributed audio outputs from an original digital audio input, for example, fed from a digital mixing desk or digital audio routing matrix. All Sonifex’s digital products are 24 bit, 96kHz compatible.
