An elaborate TOA networked system forms the core of the new audio communications system at the refurbished Radio Spares warehouse in Corby.

Retrofitted by Provoice, the audio division of Burnley-based fire protection and voice evacuation specialists, Protec, the system is based around a centrally-sited, 32-zone SX-1000 audio management digital matrix, powered by a combination of TOA VP-1240, VP-1120 and VP-1060 amplifiers, housed within a suite of five "Access Series" drive racks, manufactured by Wilshire & Quick.

There are 48 amplifiers in total, and since the system is plugging into a pre-existing PA set-up, using branched circuits, Provoice opted to use an impedance monitoring system, specially designed by TOA Germany, and featured for the first time in the UK.

Prosound's Jan Hawrot explained that the system contained four automatic messages and a computer signal indicator and test diagnostic.

The SX-1000 is ideal for both routing of simultaneous audio channels and fault monitoring and logging. It can be configured as a 64-audio input/128-audio output device, with 128 x 128 control inputs. The 16 audio busses enable 16 simultaneous processing of up to 16 audio signals, while the software-driven operation makes complicated wiring set-ups unnecessary.
A single TOA SX1200 microphone is located in the main gatehouse security room, which will be used for paging to two zones.

There are 59 wired speaker circuits and the system is interfaced with the existing Honeywill fire alarm system (although the original voice evac. system is being replaced).

The entire set-up is connected to Radio Spares' onsite three-phase UPS system.

Summarised Jan Hawrot: "The beauty of this system is that we have been able to ship the racks in sections and then connect up to the umbilical cords on site."
