DOCUMENTATION including Safety Sheet AP3345, this user guide AP5739 and the Registration Card AP3594.
The MPS12
The slimline MPS12 power supply unit 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 with no change of setting required. Full protection and thermally controlled fan cooling ensures the power unit will operate consistently.
Free standing
The MPS12 can be operated as a free standing unit for shelf or floor operation. Ensure adequate air flow around the unit. It must not be covered in any way. Always stand the unit on a firm flat surface well away from any soft furnishings or carpet.
Rack mounting
The MPS12 can be mounted in a standard 19 inch rack using the optional front panel (supplied), and will occupy 2U (3.5 inches) of rack space.
An important consideration when rack-mounting the unit is the need for natural convection of airflow around the unit. Good ventilation below the unit, in the floor or back of the rack, will ensure a continuous path for airflow.
Rack equipment known to produce a significant amount of heat should not be mounted directly below the power supply unit. Equipment which also relies on good airflow within the rack (i.e. most power amplifiers and other power supply units) should be given due consideration and some space should be provided between such units and the MPS12. Forced convection, by means of a fan-tray, may be desirable in some situations.
Location
As with any power supply unit, it is preferable to provide a degree of physical isolation of the unit from other equipment, particularly that which carries low level audio signals, to avoid any possible interference pick-up. For this reason the MPS12 power supply unit is provided with a long (2.9m) DC output cable to enable it to be positioned away from the mixing console. For the same reason, when rack-mounting it is preferable to avoid locating the unit next to signal processing equipment.
Grounding
Consideration must be given to the Grounding arrangement of the system, at the centre of which is the console and the MPS12. The console chassis is connected to the mains earth via the power supply unit. The MPS12 has audio 0V and mains earth connected internally. For safety it is important that all equipment grounds are connected to mains ground so that exposed metal parts are prevented from carrying high voltage which can injure or even kill the operator. Do not disconnect the ground connection in the mains lead. It is recommended that the system engineer check the continuity of the safety ground from all points in the system including microphone bodies, cable shields, equipment cases, rack metalwork and so on. If audible hum or buzz is present in the system due to a "ground loop", consult the console user guide for possible solutions.
Fitting in a rack
The MPS12 is supplied ready for rack mounting. For free standing use, remove the 19" front panel, which is secured by four M4x8 Pozi screws and shakeproof washers.
Do not obstruct the ventilation slots. Ensure adequate air around the MPS12.
Do not install the unit directly above or below other ment.
Do not remove the cover of the MPS12. There are no user ceable parts inside.
Read the SAFETY INSTRUCTIONS printed in the front of this user guide and on the rear panel. The MPS12 is a high performance switch mode power supply with universal mains input. It will operate from an AC mains supply voltage from 100V to 240V.
The power supply unit is provided with an IEC type mains connector and moulded mains |
Check that this is correct for connection to your wall socket outlet.
Switch the unit on by pressing the rear panel ON switch. The green ON led should light.
To avoid audible thumps and bangs through the speakers, always turn the console on before
switching on the amplifier system, and turn the amplifiers off before switching off the console power supply unit.
Always switch the power supply unit off before connecting or disconnecting the console power cables, removing or installing console modules and any servicing work. In the event of an electrical storm, or large mains voltage fluctuations, immediately switch off the power supply unit and disconnect from the mains supply.
Avoid fully extending the DC cable when plugging in as this may stress the cable and connectors
resulting in failure. Ensure that walkways, aisles and gangways are not obstructed by cables. To ensure correct performance we recommend that you do not extend or modify the DC power cable in any way.
Connecting the MPS12
The MPS12 may be used to power Allen & Heath consoles fitted with a compatible EXTERNAL DC IN socket. Connect the MPS12 DC POWER OUT cable to the EXTERNAL DC IN socket of the mixing console as shown below.
The MPS12 should only be connected to consoles specified to work with the MPS12 by Allen &
Heath. If in any doubt over its suitability for use with a particular console, please contact Allen & Heath technical support.
Using the MPS12 as a Backup Power Supply
The MPS12 is suitable for use as a redundant backup supply, in addition to a console's primary power source. Some smaller Allen & Heath consoles feature an MPS12 compatible EXTERNAL DC IN connector in addition to the built in mains power supply. These consoles have combiner circuitry to enable both supplies to run at the same time. In the event of a problem with one of the supplies, the other will take over seamlessly, without affecting the console's performance.
The MPS12 should only be connected as a backup supply to consoles specified to work with the
MPS12 by Allen & Heath. If in any doubt over its suitability for use with a particular console, please contact Allen & Heath technical support.
The MPS12 does not use any internal filters. Air is drawn through the fan grille on the side of the chassis, blown through a heatsink tunnel and out through ventilation slots in the other side of the chassis. It is not necessary to open the unit for cleaning. Simply keep the fan and ventilation slots free of dust and dirt using a vacuum cleaner and dry, lint free cloth. Do not use liquid cleaners or compressed air to clean the unit.
Always switch the unit off before inspecting or cleaning it.
Replacing the mains fuse
The AC mains fuse is located on the rear of the MPS12 unit next to the AC mains connector. In the event of a mains surge or under-rated fuse value, the fuse will rupture. Switch off the power supply and remove the mains lead plug from the "AC MAINS IN\~" socket on the rear of the unit. Check the fuse and replace if necessary. In the event of repeated failure of the mains fuse, consult your Allen & Heath service agent.
In the unlikely event of an internal DC rail fuse failure, consult your Allen & Heath service agent or Allen & Heath technical support.
TO AVOID THE RISK OF FIRE REPLACE FUSE WITH THE CORRECT TYPE ONLY, AS INDICATED THE UNIT.
