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. This section provides controls for the group routing and auxiliary sends. Controls 1-8 function according to the setting of the mode switches in the master section. These configure group routing switches and independent post-fade aux sends for FOH (front-of-house) application, or pre/post switchable sends for stage monitor application. Controls 9-16 can be configured as mono or stereo pre/post aux sends.

MAIN MIX SENDS. A single switch routes the channel signal to the main L, R and C outputs. The balance between the three outputs is determined by the LCRplus pan and blend controls. Pan can also be switched in or out of the group routing for stereo or mono groups.

INPUT FADERS. Includes the channel fader, mute, signal meter and PAFL monitoring. The 8 VCA group assignments are displayed. VCA and mute group editing and channel safe selection is performed using the mute switch with green safe/edit indicator below.

STEREO INPUT and EQ. The input preamp accepts two stereo sources with independent control of each. This allows selection of either or mixing together both sources. A fixed frequency 4 band equaliser provides shelving high and low bands and two bell mid bands. The EQ can be switched in or out.

GRP/AUX 1-8 MASTERS. These are the fader masters for channel sends 1-8, configurable using mode switches as fixed level groups or as variable level pre or post-fade auxes. The output can be routed to the main mix through LCRplus controls to create sub groups. Led meters display the pre-fade mix levels.

AUX 9-16 MASTERS. These are the fader masters for channel sends 9-16.

ROTARY AUX MASTERS. These are the rotary masters for channel post-fade aux sends 1-8. They provide the independent effects sends when the fader masters are configured as groups. They still function when the fader masters are configured as pre/post auxes but would not normally be required.

MAIN MIX FADERS. Provides separate master faders and mutes for the main L, R and C outputs. A mode switch configures the C output as the engineers wedge monitor feed for the stage monitor application.

MATRIX. This section provides all the controls for the 8 matrix outputs, including the source and master rotaries.

VCA GROUPS. These are the VCA group master faders, mutes and PAFL monitor switches. Channels are assigned to the groups using the edit key. The normal fader operating level is marked ‘0’.

MUTE GROUPS. These are the master keys that mute all channels assigned to the group. Channels are assigned using the edit key.

SNAPSHOT MEMORIES. Provides the controls to store, recall and preview the 128 onboard memories, and edit channel safes. Mute settings and/or VCA assignments can be disabled from the snapshots.

HEADPHONES / MONITOR. Provides source selection and independent control of the headphones and local monitor outputs.

SOLO-IN-PLACE. Pressed with the shift key this puts the console into SIP mode ready to solo any channel when its mute key is pressed.

PAFL CONTROL. This section controls how the intelligent PAFL system functions and provides the clear all key.

OSC/NOISE GENERATOR. Enables and selects a 1kHz tone or pink noise which can be routed to any output for line up or system testing.

INTERCOM. The console talkback mic and headphones can be interfaced to a ClearCom compatible intercom system so eliminating the need for a separate intercom headset.

TALKBACK. Pressing the talk switch routes the talkback mic to any output with its TB enable switch selected. The mic input is duplicated on the rear panel for plugging in hand held microphones.

GRP/AUX 1-8 METERS. These moving coil VU meters display the grp/aux 1-8 outputs.

LRC/PAFL METERS. The main L,R and C outputs are simultaneously displayed on both VU and led bar meters. These switch to display any PFL or AFL when selected. The display is mono or mono + stereo depending on source. The large call lamp lights to warn when the intercom is signalled.

AUX 9-16 / MTX 1-8 METERS. These meters display either the aux 9-16 outputs or matrix 1-8 levels according to the setting of the meter select switch near section.

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. You should order a spare power supply with your console in this case. Make sure the power supplies are positioned next to each other and using the same mains distribution.

RS232 Code Update

A rear panel RS232 port is provided. This is used for loading new operating software into the sidecar from a PC. It is not used for any other function. Check our Web site www.allen-heath.com for details on the latest version of ML5000 operating software and instructions on loading it into the console.

Note: The sidecar settings are archived using a MIDI or RS232 dump from the main console. There is no need to archive the sidecar settings separately.

Sidecar Audio Connections

The following information is provided for reference only. It is not necessary to wire special cables to connect the sidecar to the console. Standard 1 to 1 wired 37way cables are provided. The audio signals are balanced and operate at a nominal –2dBu line level.

Power Supply Installation

Free standing

The MPS14 can be operated as a free-standing unit without requiring any special cooling arrangement, but should not be accidentally or deliberately covered in any way. Always stand the unit on a firm flat surface well away from any soft furnishings or carpet.

Rack mounting

The MPS14 is designed as a 19 inch rack mount unit 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 air flow over the whole unit.

Good ventilation below the unit, in the floor or back of the rack, will ensure a path for continuous air flow.

Other equipment in the rack which is known not to produce a significant amount of heat should be mounted below the unit. Equipment which also relies on good airflow within the rack (i.e. most power amplifiers and other power supplies) should be given due consideration and some space should be provided between such units and between the MPS14 unit. Forced convection, by means of a fan-tray, may be desirable in this situation.

Location

As with any power supply that contains switch mode technology, 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 unit is provided with a long (2.9m) 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 adjacent to signal processing equipment.

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 would introduce audible hum or buzz to otherwise clean audio signals. Ground loops may occur where signal processing equipment patched to the console, has its signal earth connected to the equipment chassis. A ground loop is formed if the chassis of the signal processing equipment and the MPS14 chassis are in electrical contact through the fixing rails they share in the rack. The MPS14 has audio 0V and mains earth connected internally. If a ground loop is formed operation of the ground lift switch on the rear panel of the MPS14 may improve the situation.

Gain Structure (Reprinted from User Guide)

How the levels between the different signal stages are set up is referred to as the gain structure. For best performance it is important that the connected source signals are matched to the ‘normal operating level’ of the console. Similarly the levels of the connected amplifiers and destination equipment should be correctly matched to the console outputs. If set too high then the signal peaks will be clipped resulting in distortion, and if set too low then the signal-to-noise performance will be degraded resulting in excessive background hiss and noise.

Using the Meters. The ML5000 provides metering at all important stages through the signal chain. For best results operate the console with the LED bar meters averaging around ‘0’ allowing the loudest moments to reach ‘+6’. Reduce the gain if the red peak LEDs start to flash. Note that the peak leds light 5dB before actual clipping to warn that you are nearing distortion and should reduce gain. The LED bar meters have a peak response with fast attack and slow release so that fast musical transients are accurately displayed. The VU meters have a slower attack so that the average levels are better displayed. Both types of metering are useful in live sound mixing.

Matching a Source to the Console. Start by turning down the channel fader and send levels to prevent unexpected loud volumes reaching the main speakers and monitors. Adjust the GAIN control for an average ‘0’ reading on the channel meter. Press PAFL (in PFL mode) to listen to the signal using headphones, local or wedge monitor, and to view its level on the main LED and VU meters. Once the gain is correctly set you can raise the levels to bring the channel into the mix. Note that you may need to adjust the gain if you make significant changes to the EQ. Make sure that any equipment inserted into the channel is set to operate around 0dBu line level. It is best to first set the gain with inserted signal processors such as compressors switched to bypass.

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. Simply turning down the console output faders degrades the output stage noise performance and reduces the resolution of the fader movement. The output faders are best operated around ‘-10’ to ‘0’ for loudest average volume required. This allows plenty of additional headroom if you need it. If you are connecting to crossovers or speaker managers then set these for normal 0dBu operating level and use their level trimmers to correctly match to the amplifiers.

Terminology. The normal operating level is the optimum signal level for best console performance, indicated by ‘0’ meter readings. The channels operate at 0dBu and the mix stages at –2dBu for extended headroom. Headroom is the extra level available above normal to allow for loud peaks before the signal becomes clipped resulting in audible distortion. The signal-to-noise ratio (SNR) is the difference measured in dB between normal level and residual noise floor (hiss) produced by the console electronics. The dynamic range is headroom + SNR representing the maximum signal range possible from quietest to loudest.

Using the VCA Groups. Assigning a channel to one or more VCA groups lets those group faders control the level of its VCA element. Each fader provides up to +10dB boost. Note that the channel VCA allows a maximum combined fader boost of +10dB. Any more is simply ignored. It is best to operate the VCA group faders around their nominal ‘0’ position. You can also use a VCA group to reduce the overall level of a hot mix without having to adjust all the channel faders.

Final word… A little care with setting gain structure throughout the signal chain will give you the very best performance and most manageable control of the mix.

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.

Pre-fade Source. The source for the pre-fade aux sends may be changed by repositioning jumper links on each mono and stereo channel. The default factory setting is pre-insert, pre-EQ, postmute. This is usually preferred when mixing monitors from front-of-house. Select the source as pre-insert, pre-EQ, or post-EQ by setting one jumper. Select pre or post mute by setting another. Set pairs of links on the stereo channels to affect left and right signals.

Direct Output Source. The default factory setting is post-fade. This can be changed to pre-fade. Pre-fade follows the source as described above. An additional option sources the output from the AUX1 send control. This provides a post-fade direct output with level trim. If preferred, the channel feed to the AUX1 rotary master can be disabled so that adjusting the direct output level does not feed the mix. Note that this does not affect the AUX1 send to the fader master when aux mode is selected. Select the source as pre-fade, post-fade, or post-fade with AUX1 trim by setting its jumper. Set another jumper to turn the AUX1 feed to the rotary master on or off as required.

The 2-track output is sourced from the main LR mix. The factory default setting is post master LR faders. If you want to source pre-insert, pre-fader then replug the internal jumper links on the LR MIX circuit board as shown below. For stereo recording from a three channel LCR mix, or by creating a new balance from the groups, use the MATRIX outputs instead.

MIDI Mutes

Pressing any input or output channel MUTE switch transmits a MIDI Note On message. Similarly, receiving a MIDI Note On message will turn the associated channel mute on or off, unless the channel has been made automation safe.

Console mutes are mapped to MIDI Note numbers as shown in the table. Running status is supported on receive and transmit.

Transmit. Pressing a channel MUTE switch transmits the following Note On messages:

9n cc vv 9n cc 00

Where n = console MIDI channel number cc = input or output channel number vv = 3FH for mute off, 7FH for mute on

Receive. The console responds to the following MIDI Note On message:

9n cc vv (00 is ignored)

Where vv < 40 = mute off, 40 <= vv <= 7F = mute on

Archiving the Console Settings

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. You can also use the dump facility to program additional ML5000 consoles, for example when setting up duplicate shows or swapping consoles around. Simply link MIDI OUT from one to MIDI IN of the other and action the dump out facility.

Settings which are archived :

9 Current mute settings

9 Current Mute group assignments

9 Current VCA group assignments

9 Automation safes

9 Solo-in-Place safes

9 All snapshot memories

Settings which are not archived :

8 Current console operating mode

8 Current PAFL selection and settings

8 Store and auto-increment on/off

MIDI Dump Out

Connect the console to a suitable MIDI archiving device. Set the same MIDI channel number on both. Check the rear switch is set to MIDI. Hold down SHIFT M9 and press STORE M4 . The console dumps the current settings and memory contents using a SysEx message string. During this time dPo is displayed. Note that this operation can take up to 10 seconds during which time the console mutes, assignment, SIP and P/AFL operations will be interrupted.

MIDI Dump In

Connect the console to the MIDI archiving device. Set the same MIDI channel number on both. Check the rear switch is set to MIDI. Start the process using the MIDI archiver. The console current settings and memory contents are overwritten. During this time dPI is displayed. Note that this operation can take a while during which time the console mute, assignment, SIP and PAFL operations will be interrupted.

MIDI Dump Message Format

The format for dump out and in is identical. The dump data string is made up of multiple System Exclusive messages (known as packets) which contain the console information.

Transmit and Receive. The format for a single packet is as follows:

F0 <SysEx header> <packet type> <packet number> <data> <checksum> F7

<SysEx header> = 00 00 1A 50 07 VV vv nn

Where VV = software version number – unit vv = software version number – decimal nn = console MIDI channel number

<packet no.> = packet number from 0 to 127

<data> = block of console data (7-bit format)

<checksum> = checksum to allow error detection

MIDI Dump Errors

If the console or connected equipment fails to respond to a MIDI dump then check:

• The MIDI cable is good and correctly plugged

• The same MIDI channel number is selected

• The rear panel switch is set to MIDI

• Try again

If a data error is detected during a dump out or in the console display will show an error message code:

Er1 Buffer overflow Er2 Packet out of sequence / missing

Er3 Checksum error / corrupt data Er4 Invalid packet length Er5 Input timeout Er6 Unsupported block type Er7 Invalid scene number Er8 Block size error

Allen & Heath ML Archiver

The ML Archiver Windows™ utility for the PC can be downloaded from the Allen & Heath Internet site. This can be used to archive data to and from the PC via MIDI or RS232.

Check the Allen & Heath Web site for further details and loading instructions.

If you are using a MIDI sequencer to record the dump out data string then make sure you play it back at the same speed you recorded it. If you dump it back into the console faster than it was recorded some data may not load correctly.

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.

The foam fan filters can now be removed by simply sliding out of the slots.

Either clean or fit new filters depending on their condition.

Replace the filters and reassemble the power unit. Check the fans are running unobstructed before completely re-installing.

Replacing the mains fuse

The AC mains fuse is located on the rear of the MPS14 unit next to the AC mains connector. In the event of a mains surge or under-rated fuse value, the mains input fuse will rupture. Switch off the power supply and remove the mains lead plug from the “MAINS INPUT” socket on the rear of the unit.

Check the fuse and replace if necessary.

TO AVOID THE RISK OF FIRE REPLACE FUSE WITH THE CORRECT TYPE

ONLY, AS INDICATED ON THE UNIT
