Important Safety Instructions WARNINGS - Read the following before proceeding : CAUTION ATTENTION: RISQUE DE CHOC ELECTRIQUE – NE PAS OUVRIR Read instructions: Retain these safety and operating instructions for future reference. Adhere to all warnings printed here and on the console power unit. Follow the operating instructions printed in the user guide and the power unit user guide. Do not remove covers: Operate the power unit with its covers correctly fitted.
Important Mains Plug Wiring Instructions. The power unit is supplied with a moulded mains plug fitted to the AC mains power lead. Follow the instructions below if the mains plug has to be replaced.
ML5000 Key Features The Allen & Heath ML5000 is a large format VCA equipped dual function live sound console. It can be quickly configured for front-of-house (FOH) or stage monitor mixing. As one console suitable for both applications it is equally well suited to installation, rental and touring.

MONO INPUT and EQ. The input preamp matches microphone or line level signals to the console. The sweepable high pass filter removes unwanted low frequency sounds below the selected frequency. The channel insert is post filter, pre EQ. A swept frequency 4 band equaliser provides shelving high and low bands with adjustable shelf frequency, and fully parametric high and low mid bands with adjustable centre frequency and Q. The filter and EQ can be independently switched in or out. GRP/AUX SENDS.

The Expander Sidecar The Allen & Heath ML5000-24SC Sidecar is the 24 mono input channel expander for the ML5000 console. It is free standing and does not need to be mechanically fixed to the main console. Interconnection is by means of multiway cables to link the audio signals and control logic. It is supplied with its own power supply unit independent of the console. The input channel strip is identical to the main console with all functions available.

Combining Sidecar Power Supplies for Backup If you are connecting two sidecars then you can link the power supplies together for redundant supply backup. One MPS14 supply is capable of running both sidecars together should the other fail. You need to order the short 0.7 meter DC power cable (part 002-584) for linking. Note: Do not link the main console power supply to the sidecar supply in this way. One supply is not capable of running both the main console and its sidecar should the other fail.
The MPS14 Power Supply The slimline MPS14 power supply uses linear post-regulated 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.

Gain Structure (Reprinted from User Guide) Matching the Console to Destination Equipment. The console produces a standard XLR output level of 0dBu for a meter reading of ‘0’ and +22dBu maximum to allow plenty of headroom for driving equipment hotter. If you are connecting directly to a sensitive power amplifier it is advisable to turn down its input trim control if the normal console level is too high.
Channel Jumper Options 2-TRACK Jumper Options Several link options are available to satisfy user preferences. These require removal of the console base panels and replugging of 2way jumpers on the circuit boards. It is not necessary to remove assemblies from the console. To avoid damage to the internal assemblies this work should be carried out by competent technical personnel. The 2-track output is sourced from the main LR mix. The factory default setting is post master LR faders.

Archiving the Console Settings MIDI Dump Message Format The console settings can be saved to an external device such as a MIDI sequencer or data archiver using the dump out facility. Saved settings can be loaded back into the console using dump in. This is ideal when you want to archive the settings to use at a later date, for example a re-run of a previous performance.
Operating Software Technical Support Operating Software Version Number Power Up and Power Down The version number is briefly shown on the snapshot display on power up. Make sure the system amplifiers are muted or turned off before switching the console on or off. This example displays version 1.20 The console settings are saved when power is removed. On power up these settings are restored.
Servicing the Input Fader assembly Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. Remove the numbered Ident strip by placing a flat headed screwdriver under one end and prizing it upwards. Remove the Ident strip by ‘peeling’ it from one end of the console to the other.
4) Carefully remove the Fader Slave PCB from the Mono Fader PCBs by pulling it upwards from the fader boards. 5) Once removed, turn the Fader Slave PCB over (see fig.3) To remove a Mono Fader PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed Screws (E) that attach the Mono Fader PCBs to the Input Fader Bracket (see fig.3). To remove a fader remove the two relevant M3x5 Countersunk Pozi Screws with under-head pips (C) as shown in fig.1.
Servicing the Master Fader assembly Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. Remove the numbered Ident strip by placing a flat headed screwdriver under one end and prizing it upwards. Remove the Ident strip by ‘peeling’ it from one end of the console to the other.
The Stereo Slave PCB must be removed before the following PCBs can be removed; Mono Fader, Master Fader Centre, Master Fader L/R & Control Panel. 1) Cut the 2x Cable ties attaching the Stereo Slave PCB onto the Mono Fader & Control Panel PCBs. 2) Carefully remove the Stereo Slave PCB by pulling it upwards. 3) Once removed, turn the Stereo Slave PCB over. 4) To remove a PCB, use a 5.5mm spanner to remove the relevant M3x4 Taptite Hex Headed Screws that attach the PCBs to the Master Fader bracket.
Base removal and Internal PCB assemblies Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. Before you can access the internal PCB assemblies, invert the console and remove the screws securing the base in place. Carefully lift the base off.
Removing a Mono Input PCB assembly Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. 1) Remove the screws attaching the relevant Earth Strip running the length of the Mono section (see fig.6, right hand section only shown) then lift away the Earth Strip. Earth Strip 50 way IDC wireform SYS-LINK II PCB fig.
Removing the Master Distribution PCB assembly To access the Group and Auxiliary PCB assemblies it may be necessary to remove the Master Distribution PCB. Before beginning any service work, remove all power to the unit and disconnect any signal cables where necessary. Ensure adequate lighting and use the correct tools. 1) Before removing the Master Distribution PCB assembly, the console base must first be removed.
Servicing the Meterbridge Assembly Before beginning any service work, remove all power to the unit. Ensure adequate lighting and use the correct tools. 1) Remove all the plastic snap-in rivets along the face of the meter panel with your fingernails or other non-abrasive tool. 2) With a person standing at either end of the console, each using a small, thin screwdriver, place the screwdriver through each of the endmost bottom rivet holes (see fig 8).
Servicing the MPS14 Power Supply Cleaning and Replacing the fan filters. At regular intervals, it is recommended that the 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. To remove the fan filters, switch off and disconnect all power to the MPS14. Remove the rack ears and place to one side. Remove the cover fixing screws and cover and place to one side.
