Introduction to the XL4
The XL4 was born out of a dream to design an analogue state of the art live mixing
and recording console with unparalleled performance/features intrinsic with intuitive
layout and operation. The vision required the analogue sound path to be controlled in
the digital domain via a high degree of signal routing and moving fader automation
enabling the live sound engineer whether in a touring or theatre production
environment to utilise automation functions in order to enhance mix efficiency and
performance to performance consistency.
The benchmark for the XL4 was the XL3 console which during production since 1990
gained a worldwide reputation for unequaled sonic performance and system
transparency culminating in its award for best live sound mixing console 1993 and
1994.
Bob Doyle, Midas Sales & Marketing Director, spent ten months finalising the XL4
specification, discussing its concept with world class sound engineers and rental
company heads as well as theatrical production designers and artists alike. The criteria
was to develop a mixing environment which enhanced the creativity of the mixing
engineer by automating the repetitive functions of specific mix and cue requirements,
thus leaving he or she free to concentrate on the main thrust of live mixing by
reproducing the Artist’s music as it should be.
In our opinion, the XL4 combines all these criteria in a coherent, easy to operate
mixing aid with unsurpassed sound and sonic quality.

Midas XL4 Features
48 Mic Inputs.
The XL4 features a new mic amplifier which further improves on the XL3 design giving increased
gain range and lower distortion whilst retaining the XL3's constant HF bandwidth topology which
assures excellent amplifiers stability, RF rejection and noise performance at all gains.
Direct Outputs.
Every input module is fitted with a direct output as standard with its own level control and front
panel switching which selects the source from post fader, pre fader or pre insert and equaliser.
16 audio sub groups.
The 16 main audio groups can be assigned to any of the 8 automute groups and to VCA control
from any combination of the 2 motorised grand master faders. A safe switch is again included for
each group. The input for the groups is normally derived from the 16 group busses but for monitor
applications the fader change over routes the 16 mono aux busses to the group faders.
Line inputs.
A separate Hi Z line input with its own dedicated gain control is incorporated which is ideal for
playback of recorded material. Global change over from mic (record) to line (playback) is easy
because it is under automation control.
Equaliser.
The sonic performance of the legendary XL3 equaliser is maintained including the full parametric
mid's and traditional Midas bass and treble shelving responses. In addition the treble and bass
sections now have an extended frequency range and are switchable to full parametric operation.
Inserts.
Each channel has a half normalised fully balanced insert send and return point which can be
switched in or out from the front panel and set as either pre or post equaliser.
Input metering.
These peak reading meters cover a 60dB range in 3dB steps and can be switched globally to
monitor pre fader signals or pre insert and equaliser signals.
Audio busses.
Each channel can be routed to any combination of 42 audio busses comprising of 16 mono aux'es,
8 stereo aux'es, 16 stereo groups and 2 stereo masters. All this is switchable on the module front
panel but also via the automation control.
VCA and mute busses.
Each channel can be controlled by any combination of the 10 motorised VCA master faders and 8
mute masters. Assignment of these busses is again switchable on the module front panel or by the
automation control. A safe switch disconnects the channel from all mute groups and an isolate
switch removes the channel from all VCA control.
Group aux inputs.
An additional 16 inputs with treble and bass equalisation can be routed directly to the groups or via
a pan to the masters mix and can be further controlled by assignment to any of the 10 VCA masters.
Master.
The stereo master module provides the main left and right console outputs plus 4 more record
outputs and a mono output. A solo to master facility is incorporated on the left, right and mono
outputs to aid the engineer at sound checks.
Matrix.
As standard the 8 matrix outputs derive their signals from the 16 audio groups, left and right
masters creating a 18 X 8 matrix. The module also houses the stereo aux masters which have their
own outputs at all times but which can be routed directly into the matrix giving an additional 48 X
8 matrix sourcing direct from the input channels.
Output meters.
28 peak reading meters (each covering a 60dB range in 3dB steps) are used to monitor all the main
outputs i.e. 16 groups, 8 matrix, 2 masters and 2 local outputs. They and can be switched globally
to monitor pre fader or post fader signals and can also be used to monitor the 24 aux outputs.
Automutes.
The 8 automute masters can be assigned to any input or audio group and act on pre fader and post
fader signals. Apart from assignment the operation of these mutes is entirely independent of the
automation system.
10 input VCA faders.
10 motorised VCA master faders control the channel and aux inputs whilst a further 2 VCA grand
master faders control the audio groups. Each VCA master has a solo switch which gives the
engineer an opportunity to monitor the signals within the VCA subgroup. Also incorporated is a
VCA mute which act on post fader signals only and effectively adds a further 12 automute scenes
to the existing dedicated automutes.
Automation.
The automation system can store and recall up to 2000 scenes. All channel routing and major
functions are automated as well as all major output mutes. The 12 motorised VCA master faders
give dynamic control of signal levels within the console and all automation information can be
exported or imported in a variety of different mediums for storage or console and system linking.

FUNCTION: To control microphone and line input levels with phantom and phase reverse
facility plus incorporating high and low pass filters.
1
The PAD switch gives 20dB
of attenuation to the mic
signal and will allow the
connection of high output
microphones or line level
signals. If the mic amp is
transformer coupled ( option )
the pad greatly reduces the
risk of saturation at very low
frequencies.
The 48V switch connects 48
volt phantom power to the
mic input suitable for a
condenser microphone or DI
box.
The METER monitors the
peak signal level of the input
channel pre fader. When the
GLOBAL METER CHANGE
OVER switch on the
COMMS module is activated
the meter monitors the mic
amp or line amp output
(which ever is in use ).
The PHASE switch activates
a 180 degrees phase change
on both the mic and line
inputs. This switch is under
automation control.

The LINE control gives
continuous adjustment of the
line amp gain from - 20dB to +
20dB.
The LINE switch connects the
line input to the signal path and
disconnects the mic amplifier.
This switch is under automation
control.
The LO PASS filter control acts
on the mic input only and is
continuously adjustable from
1K to 40K. When the filter is
set to 40K there is no loss at
20K.
The HI PASS filter control acts
on the mic input only and is
continuously adjustable from
10Hz to 400Hz. When the filter
is set to 10Hz there is no loss at
20Hz.

i. They are used to assign the
input channel post fader
signal to the 16 AUDIO
groups via the pan control.
ii. They are used to assign the
input channel to the 10 VCA
sub groups.
iii. They are used to assign
the input channel to the 8 auto
MUTE groups.
The function of these
switches is globally selected
by pressing the large AUDIO,
VCA or MUTE switches on
the AUTOMATION
CENTRAL CONTROL
panel. A fourth large switch
LOCK is used to disable all
the input channel group
assign switches throughout
the console so as to avoid
accidental operation. It is still
possible to view the switch

FUNCTION: Moving fader control of 10 VCA sub groups and 2 grand masters with facility to meter and
solo listen.
21
The ISOlate switches
disconnect the vca sub group
faders and mutes from
automation screen recall.
Screen storage is still active.
1
i so
The vca MUTE switches
mute any post fader input
channel signals which are
assigned to the corresponding
mute
solo
Note i. If large numbers of inputs are
assigned to one vca sub group, there
will be a higher than usual signal level
sent to the solo busses when the vca
solo is active (+ 6 to + 10 dB approx.).
10
The VCA GROUP faders are
motorised and under
automation control. They give
continuous adjustment of the
vca sub group gains from
+10dB to off.
Note ii. When vca solo switches are
active the PFL buss also receives
signals from the vca sub group inputs
but it will NOT be a true
representation of the relative levels
within the vca sub group. This feature

The vca SOLO switches are
used to monitor VCA sub
groups by creating a
corresponding AUDIO sub
group on the stereo AFL busses.
All input channels and line
returns that are assigned to a
specific vca sub group will be
summed onto the solo busses
when that vca solo is active.
The ISOlate A and B switches
disconnect the grand master
vca A and B sub group faders
and mutes from automation
screen recall. Screen storage

The vca MUTE A and B

group post fader signals
which are assigned to the
grand master A or B vca sub
groups.

The grand master A and B vca
SOLO switches are used to
monitor the grand master A and

a corresponding AUDIO sub

that are assigned to grand
master vca A or B will be
summed onto the solo busses

Note i. When a grand master vca solo
switch is active the PFL buss also
receives signals but they are NOT a
true representation of the relative
levels within the grand master vca sub
group. This feature is however useful
as it allows confirmation of signal
present and signal quality when the
grand master vca fader is down or
muted. It is therefore important to
know the status of the PFL
MONITOR switch on the COMMS

vca solo switches.
Note ii. If a grand master vca solo
switch is pressed for a short time it
will latch on or off, but if it is held on

The mono INS switch

The VCA switch connects the
mono vca fader to the stereo

The mono SOLO switch
sends the mono master signal

Midas XL4 Automation system
Introduction.
Automation system overview.
The MIDAS XL4 is an ‘intelligent’ live mixing console. It utilises microprocessor technology to
provide the operator with unprecedented features for a live console, whilst remaining easy to use and
retaining the familiar look of a normal console.
The update speed of the MIDAS XL4 automation was a high priority of the system design, the
entire console is capable of updating itself over fifty times a second. Thus the delay between pressing the
‘RECALL’ button and the desk update is negligible.
Some sound engineers harbour concerns about giving control of a sound system over to
computers, in the case of the MIDAS XL4 these concerns are unfounded. For one thing, the MIDAS XL4
is a ‘computer assisted’ console. Most of the audio functions may be controlled without the aid of
microprocessors, and all audio functions may be controlled without the central control CPU.
With the exception of the central controller CPU, the microprocessor chips used are ‘single chip
micro’s’ or ‘microcontrollers’. The CPU, program memory, RAM, data converters and timers are all
housed in a single chip. This gives the utmost in reliability as the ‘computer’ itself is protected from the
outside world by it’s input/output ports.
Fifty microprocessors (in a standard 48 input console) split the workload, resulting in high speed
operation and also providing the large degree of protection required for live performances. Should one
microprocessor ‘fall over’ the others will continue to operate normally.
In addition, the system has been designed is such a way that if a microprocessor does fail, the
audio circuits controlled by that unit will usually remain active in the state last recalled. The chances of a
microprocessor failing in such a way as to reconfigure its audio control circuits are extremely remote. The
most likely indication that a microprocessor has failed will be that it fails to respond to the central control
CPU. The audio circuits will continue to work.
Important controls such as the MUTE switch, whilst they can be over-ridden by microprocessor
control, will work without the intervention of a microprocessor.
Each input channel has its own microprocessor, the VCA master section has one and the final
microprocessor is in the central control section.
All the microprocessors are located in the fader bay of the XL4. No audio passes through the fader
bay, allowing a high degree of immunity to digital breakthrough to be achieved.
The use of multiple processors also means that the software, instead of being one large program, is
broken up into a number of small programs which are easier to test and debug, minimising the chances of
software problems.

Midas XL4 Automation system
The Central control unit.
The MIDAS XL4 Automation is controlled from the central control CPU mounted to the right of
the VCA Master faders.
The top four switches, labelled ‘AUDIO’, ‘MUTE’, ‘VCA’ & ‘LOCK’ are not directly part of the
central control CPU, these switches directly control the operating mode of the input fader automation.
(See Input fader mode control, later).
The central controller CPU has been developed by OUTBOARD ELECTRONICS Ltd. in
conjunction with MIDAS. The operation of the MIDAS XL4 Automation system is based on the control
system used on the OUTBOARD ELECTRONICS SS20 Moving fader system. Many operators used to
the SS20 will find operating the MIDAS XL4 Automation system very familiar.
Control of the system is achieved with eight buttons and a ‘jogwheel’. Operator feedback is done with
two displays, a four character ‘scene number’ display and an eight character ‘scene name’ display.
Auxiliary functions are accessed through a series of menus.
The main 1 Meg of internal memory is battery backed up and may also be downloaded on to a memory
card.

Midas XL4 Automation system
Operating the system.
Input fader mode control
The top four switches of the central control unit, labelled ‘AUDIO’, ‘MUTE’, ‘VCA’ & ‘LOCK’
directly control the operating mode of the input fader automation.
With the ‘AUDIO’ mode enabled, the fader bay switch bank controls the audio group routing.
Only switches 1-8 are used. Switches 9 & 10 are used to trigger a input moving fader calibration on the
input channel (when fitted, if no moving fader is fitted the function will time out). To use this function
press switch 9. The LEDs associated with switches 9 & 10 will flash. This indicates that the clear function
is ‘armed’. Pressing switch 10 will clear the channel.
If switch 9 is pressed, arming the calibrate function, and it is not desired to calibrate the channel,
pressing switch 9 again will disarm the clear function.
With the ‘MUTE’ mode enabled, the fader bay switch bank controls the automute assignments.
Only switches 1-8 are used for automutes. Switches 9 & 10 are used for the channel clear function.
The channel clear function resets all computer controlled settings on that channel to off. To use
this function press switch 9. The LEDs associated with switches 9 & 10 will flash. This indicates that the
clear function is ‘armed’. Pressing switch 10 will clear the channel.
If switch 9 is pressed, arming the clear function, and it is not desired to clear the channel, pressing
switch 9 again will disarm the clear function.
With the ‘VCA’ mode enabled, the fader bay switch bank controls the VCA assignments.
When the system is ‘locked’ (with the ‘LOCK’ switch illuminated) the three operating modes may
be called up, allowing the state of the switches to be seen, but the switches will not operate. This is to
prevent accidental operation of the fader bay switches.
SystemStart up
Following power up, the alpha-numeric display will briefly show the software release version,
followed by ‘READY’. This indicates that the initialisation is complete and the system is ready for use.
The system powers up in the ‘locked’ state. In this state scenes may be recalled but not stored. All
functions which modify the stored data are disabled until the system has been unlocked.
Unlocking The System
To unlock the system after start up the following procedure must be followed. Press the SYSTEM
button and UNLOCK will be displayed in the right hand screen. Press the YES button and the left hand
window will change to read 1200, using the jog wheel alter this screen until the correct password is
displayed. This password is found on the insert provided with this manual or can be obtained from Midas.
Page 7
Midas XL4 Automation system
Scene storeage
Storing scenes may only be done when the system is unlocked.
To store a scene, first display the position you wish to store the scene in on the left hand window
by using the jog wheel. Scene 0000 is a preset scene and can not be overstored. Once the required position
is displayed press the ‘STORE’ button. The display will respond with ‘NEW’, if the scene does not yet
exist or ‘OVERSTORE’ if the scene does exist.
Following a scene store operation, the scene number is incremented by 1 or 0.1 depending on wether the
scene was expanded previously.
Scene recall
Recalling scenes is achieved using the ‘LAST’, ‘NOW’ and ‘NEXT’ buttons, and also using the
jogwheel.
Pressing the ‘NEXT’ button causes the system to step to the next scene number in memory and
recall it to the console. After the last scene has been recalled, pressing ‘NEXT’ will cause the display to
show ‘END’ and no other operation will occur.
Pressing the ‘LAST’ button causes the system to step to the previous scene number in memory
and recall it to the console. After the first scene has been recalled, pressing ‘NEXT’ will cause the display
to show ‘START’ and no other operation will occur.
Pressing ‘NOW’ will recall the scene number currently shown in the left hand section of the
display. This number may be adjusted using the jogwheel.
When the system is locked the jogwheel will only use the numbers of scenes that exist in memory.
No operations other than recall are available while the system is locked.
When the system is unlocked the jogwheel adjust the scene number in increments of one whether
the scene exists or not. Attempting to recall a scene number which does not exist will result in the
message ‘EMPTY’.

be used to select the required channel. When the required channel number is displayed, press the ‘YES’
button to enter it.
AUTOMIDI
This function when enabled automatically places a midi out message with every scene stored (0 to 99
only). This message is sent out on the midi channel selected using the MIDI CH selection. For example if
scene 0100 is stored after automidi is enabled, when recalled a program change one will be sent from the
midi out port on the midi channel selected in MIDI CH.
RS-LINK
This function allows you to enable and disable the RS link on the rear of the console (RS232-2). Pressing
the ‘YES’ button when this is displayed in the left hand display will then allow you to choose YES or NO
using the jog wheel. Once you have choosen pressing ‘YES’ will save your choice and drop you back out
of the menu. This function is used when 2 XL4s are linked, enabling the one consoles automation to
follow the others. You can either make one the consoles a master slave combination by disabling the
RS232 in one console or control the recall of the automation from either console if they are both enabled.

This is a continuous read/write test as a speed set by Test 1.
Test 4
This is a system memory test, the automation control system will write and read to each bit of
memory individually and check for any errors. This test is extreamly time consuming and special
equipment is needed to see any results as there is no decipherable error messages are shown on the display
if a fault is found.
WARNING!
During the test modes, the motorised faders should be disabled using the ‘ISOLATE’ switch.
Allowing the faders to attempt to keep up with the test function for long periods may damage the servo
drivers.

New scene.
If the scene number does not yet exist, the display will respond with ‘NEW’. To create the scene
press ‘YES’. The scene will be created and the current status of the console will be stored in it.
The scene number may be adjusted using the jog wheel before pressing ‘STORE’. The scene
number may be adjusted before or after setting the desired console configuration.
Should ‘STORE’ be pressed in error, the ‘NO’ button will exit the procedure without taking any
further action.
Page 15
Midas XL4 Automation system
Overstoring
If the scene number does exist, the display will respond with ‘OVERSTORE’. To update the scene
press ‘YES’. The existing scene will be replaced with the current status of the console.
Pressing ‘NO’ will abandon the store procedure without taking any further action.
X-FADE (Crossfade).
This allows the faders crossfade speed to be adjusted from 0.5 to 10 seconds in 99 equal steps.
The speed is set using the jogwheel, pressing ‘YES’ then stores the scene.
WARNING When editing the crossfade speed it is important to note that the speed you leave set in the
left hand window will be applied to any scene stored or overstored after.
Expand.
This is used to set the scene number increment value to use the decimal places. This is used when the
number of expected scenes is greater than 99. It causes the auto-increment to step in 0.1 steps instead of 1.
Insert
This option allows extra scenes to be inserted between existing scenes. To insert a new scene dial up the
number of the scene that you wish to come after the new scene. The scene will be inserted before the
scene displayed.
The new scene will be given the number of the previous scene plus point five.
Once an extra scene has been added, decimal place numbered scenes will be accessible between the
previous scene with a whole number and the next scene with a whole number.
This can occur to two levels, that is scenes may be stored between decimal place numbered scenes using
the ‘hundredths’ digit as well.
Delete
This option is used to delete the current scene from memory. There is currently no way to restore a scene
once it has been deleted, so this function should be used with caution.
Edit
EDIT calls up a further sub-menu for editing facilities.
Sc. NAME
To enter or edit a scene name, dial up this option and press ‘YES’.
The character in the left hand position of the scene name display may then be adjusted using the
jogwheel. When the desired character is visible, press ‘YES’ again and the character will be stored. The
next character on the right may then be adjusted. Continue until all eight characters have been entered,
when the normal system operation will resume. To leave a character as it is, press ‘YES without moving
the jogwheel.
Page 16
Midas XL4 Automation system
MIDI IN
This function allows you to edit the midi program change that the scene will be recalled by when
received. The XL4 will monitor the midi channel set in the CH.MIDI in located in the SYSTEM Menu.
MIDI CLR
This function allows you to clear all the mikdi information associated with the particular scene you are
on.
This function is used to set up a MIDI message which will be transmitted whenever the scene
containing the message is recalled.
MIDI OUT
This function allows you to edit the 8 possible midi out messages the console can send out when a scene
is recalled.
To program the multiple-midi outputs the following procedure must be followed.
1/ Press STORE and scroll the screen using the jogwheel until EDIT is seen, press the YES button.
2/ Scroll the screen until MIDIOUT is seen, press the YES button.
3/ You may now select one of the eight midiout messages for editing. This may be done using the
jogwheel. When the required message number is displayed in the left hand window press the YES button.
4/ In the left hand window the midi channel the message is sent out on will be displayed. This may be
changed using the jogwheel, when the required channel is selected press YES.
5/ Using the jogwheel you may choose one of the following to edit in the right hand display NOTEOFF,
NOTEON, PROGRAM and CLEAR when the required perameter is displayed press YES. CLEAR will
delete that particular message from the group sent with that scene change.
6/ The chosen perameter may then be changed using the jogwheel and selected by pressing YES when the
required value is displayed.
7/ When all the midi out messages have been edited to exit scroll through the message list until 9 EXIT is
displayed and press YES.
NB:
This Function edits the Midi information for the last scene recalled using the Now, Next or Last
button.

Alt Scene Buttons A1 and A2
These buttons allow the recall of a scene assigned to the switch with a single button push. To assign a
scene to either ALT1 or ALT2, recall the scene you wish to assign. Press the STORE button, the right
hand screen will now read either NEW or OVERSTORE. Press the ALT button that you wish to assign
the scene to, the screen will read OK. The scene will now be recalled when ever that ALT button is
pressed. To place a different scene to the button follow the above procedure and the new scene will
automatically be overstored to the ALT button pressed.
Using the system - general hints and tips.
Setting up a console can be a laborious process, setting it up separately for multiple scenes could
be worse!
Make use of the facilities to minimise the work. If you have already programmed in a scene which
is similar to the one you wish to create, RECALL it, make the required alterations then dial up the number
of the new scene you wish to create and STORE it.
Backing up.
At the end of a rehearsal session it is good practice to save the data entered to the RAM card. By
using three or four RAM cards and rotating them you will always have the last three or four sessions
saved ready to be reloaded in an emergency.
