Sonifex Exhibit New Distribution Amplifiers At BVE 04

5th December 2013

Sonifex are exhibiting new distribution amplifiers on stand J01 at BVE 2014.

The RB-DDA6A3 digital distribution amplifier is used for distributing AES3id digital audio, repeating both the audio data and the status information of the input whilst re-normalising to standard digital audio levels. It has a single BNC AES3id audio input which is distributed to 6 BNC AES3id audio outputs.

Applications include distributing audio from a BluRay player to recorders, or feeding multiple studios with an output from a master clock.

The RB-DA24MD is a 24 way audio distribution amplifier, with 2 inputs which can be individually routed to 12 outputs or mixed and routed to all 24 outputs. The inputs can be configured as either dual mono, input 1 routed to outputs 1-12 and input 2 routed to outputs 13-24, or mixed-mono, inputs 1 and 2 mixed at a pre-set level and routed to all 24 outputs.

This product was designed for a niche application of distributing a mono or stereo audio feed to multiple active speakers for an emergency audio distribution system. The customer has a number of office desk clusters, each with a small speaker mounted underneath them, so that in the event of an emergency, everyone in the building gets a clear emergency signal. Because the RB-DA24MD has so many outputs, they can cover 100 desks with only 5 units.

The XLR inputs and D-type outputs are electronically balanced and can be wired unbalanced. Each output is individually buffered so that a short circuit on one won't affect the others. Each output is also protected against connection to both POE (power over Ethernet) and phantom power circuits.

The RB-DA24MD has master gain controls for both input 1 and input 2 which are pre-set potentiometers accessible through the rear panel. These controls allow the gain to be adjusted from -15dB to +15dB, useful for normalising consumer to professional signals and vice versa. An LED power indicator on the front panel shows that the unit is powered. Also a 125Hz 6dB per octave roll off filter can be switched in.
