Sonifex has added a new audio distribution amplifier to its Redbox audio range.

‘We designed this product for a niche application of distributing a mono or stereo audio feed to multiple active speakers for an emergency audio distribution system,’ says Sonifex Sales Manager, Richard Butlin.

The RB-DA24MD was designed in response to a particular request before becoming a ‘standard’ Redbox: ‘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,’ Butlin explains. ‘Because it has so many outputs, the system can cover 100 desks with only five units.’

The RB-DA24MD is a 24-way amplifier, with two inputs that 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 & 2 mixed at a preset level and routed to all 24 outputs.

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 Inputs 1 & input 2, which are preset 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/octave roll-off filter can be switched in.
