25 The Wandsworth Digital Sound System is primarily for use in hospitals, enabling the selection of up to sixteen programmes, either TV, FM or AM radio and auxiliary inputs. These digital signals are distributed from a modular master unit via one four-core screened data cable. This low cost, lightweight       data cable reduces installation time and simplifies connections. Isolation techniques ensure that faults are localised and do not affect the rest of the system. The system is flexible, allowing easy expansion or modification after installation, and all module receiver types are interchangeable. Digital signals significantly improve sound quality, resulting in less interference, and the sound from all TV stations can be distributed, offering listening choice to patients. QD580 Master Chassis and Modules The master chassis is supplied as a complete assembly and contains the power supply, encoder and monitor modules with all their relevant connections in the outer case. This master chassis is then ready to accept the receiver modules of your choice, and if necessary the blank panels. A modular concept unit 450mmW x 182mmH x 400mmD housing the power supply, encoder and monitor modules. Receiver modules are ordered as required. The unit is finished in light and dark grey with the module fronts of anodised aluminium. QD582 Dual Encoder Used to replace the original encoder in the QD380 DSS Master Rack Assembly and provide two data outputs for DSS systems and two data outputs for DCS systems. Monitor Module Each individual channel may be monitored by the channel select push button and indicator. A frequency meter shows the station that each receiver is tuned to; a level indicator allows accurate tuning and a stethophone driver enables audio quality checks to be made. Power Supply Module Includes On/Off switch and supply indicators. Provides isolation from th ...
