Introduction This user guide presents a quick reference to the MPS14. We recommend that you read this fully before starting. Included is information on installing, connecting and operating the power unit along with panel drawings and technical specification. For further information on the basic principles of audio system engineering, please refer to one of the specialist publications available from bookshops and audio equipment dealers.
The MPS14 The slimline MPS14 power supply uses switch mode technology to generate the DC voltages required by the console. It will operate from a wide range of ac mains input voltages. Full protection and thermally controlled fan cooling ensures the power unit will operate consistently. The MPS14 also has a built in combiner for connection to a second supply for backup.
Earthing Finally, some consideration should be given to the earthing arrangement of the system, at the centre of which is the console and the MPS14. The console chassis is earthed, to the mains earth, via the power supply. When rack-mounting the MPS14 care should be taken to avoid any possible “ground loops” in the system which may introduce audible hum or buzz to otherwise clean audio signals.
Cleaning and Replacing the fan filters. At regular intervals, it is recommended that the two foam fan filters are cleaned or replaced to ensure efficient operation of the power unit. Failure to do so may reduce the efficiency or even damage the power unit. Use a vacuum cleaner to remove dust from the air intakes on the rear of the power unit If the filters need replacing contact your nearest service agent or Allen & Heath dealer.
