The Lidl Regional Distribution Centre (RDC) in Northfleet near Gravesend is a very large storage, warehousing and distribution facility. Our client required a site wide audio system to help co-ordinate the various logistics processing as well as playout of radio based Background Music (BGM).

For the warehouse areas, our design solution for this project was based on traditional 100v line for primary distribution to speaker line circuits and loud speakers. Six audio zones were created and installed. Multi-zone, multi-channel power amplifiers were specified to provide independent zone volume control. Importantly, this design approach also provided improved resilience should one speaker zone and/or speaker line fail, the remainder of the system to continue functioning. The installed loudspeakers were positioned at a high level throughout the warehouse (positioned away from possible contact with fork truck rack loading). Full frequency, 2-way music projector speakers were installed to provide excellent audio quality reproduction and a wide distribution at ground / ear level.
For the office areas, again our design was based on 100v line audio. A simple, single zone was installed, with local volume controls for levels within the different rooms / areas. Voice only audio was limited to this zone (no radio/music required).
An IP / SIP telephony interface was installed to enable announcement and audio routing from telephones – providing additional location flexibility for users.
