XL4 Introduction The XL4 is the pinnacle in the current range of Midas consoles. Designed around the classic high quality associated with analogue circuitry which was proven with the XL3 Live Performance and Theatre console. The requirements associated with the broadcast environment was designed into the original XL4 specification. These include, moving faders on all 48 Inputs and 12 VCA’s including remote machine starts, instant access to AFL/PFL, Snapshot automation to include audio follow video, direct outputs on each input, 16 Mic/Line level returns with VCA routing for total control over effects and ambient microphones as well as full communications module.

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.

The PRE INS & EQ switch re configures the direct output to derive signal from the input channel pre insert and The PRE FADE switch re configures the direct output to derive signal from the input channel pre fader. The treble WIDTH ( dual concentric bottom ) control gives continuous adjustment of bandwidth from 0.1 to 2 octaves with a 0.5 octave centre detent. This only operates when the BELL switch is activated. The treble BELL switch converts the treble equaliser from traditional MIDAS shelving response to full parametric operation. The HI MID ( dual concentric top ) control gives continuous adjustment of boost and cut from + 15dB to - 15dB with a 0dB centre detent. The EQ switch connects the equaliser in the input channel signal path and is under automation control. The LO MID ( dual concentric top ) control gives continuous cut from + 15dB to - 15dB with a 0dB centre detent. The INSERT PRE EQ arranges the input channel signal to pass through the insert point before the equaliser when activated and after the equaliser when not activated. The BASS ( dual concentric top ) control gives continuous adjustment of boost and cut from + 15dB to - 15dB with a 0dB centre detent. The bass BELL switch converts the bass equaliser from traditional MIDAS shelving response to full parametric operation. 4

FUNCTION: Fader control of 48 input levels to stereo bus, audio sub groups and VCA sub groups with solo and mute group assign.
13
The ISOLATE switch disconnects the input channel from automation scene recall. Scene storage is still active. The SAFE switch disconnects the input channel mute from the 8 auto mute busses.
The GROUP ASSIGN SWITCHES 1 to 10 are under automation control and perform 3 major functions:-
isolate

1&2 2
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 status of all three group types when in this mode.

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 is however useful as it allows confirmation of signal present and signal quality when the vca fader is down or the vca sub group is muted. It is therefore important to know the status of the PFL MONITOR switch on the COMMS module before using the vca solo switches.

The SOLO IN PLACE switch disconnects the three pre insert master signals ( left, mono and right ) and replaces them with the stereo AFL solo busses. This does not effect the master to matrix feeds which means the matrix mixes can be "solo in placed" on the master outputs.
The mono INS switch connects the mono insert return signal to the mono mix. The VCA switch connects the mono vca fader to the stereo master fader so that the mono output tracks any changes of the stereo master fader. The mono SOLO switch sends the mono master signal to the PFL and AFL solo busses. If the switch is pressed for a short time it will latch on or off, but if it is held on for more than 1 second the latching is disabled and when the switch is released the solo will turn off. The master mix signal can not be sent to the solo busses while any other solo is active.

The COMMS ON switch sends the comms headset mic amplifier signal to the comms output / input connector. The LINK switch connects the talk mic to the intercom in such a way that the talk mic, headphones and PFL speaker output can send and receive (respectively) "clearcom" signals as well as the headset. When in LINK mode the COMMS ON switch activates the talk mic onto the comms system with the side tone cancel circuit preventing howl round.
The AUTO MUTE GROUP MASTER switches (1 to 8) activate the mute circuits on any appropriately mute group assigned input channel or audio group.

The GLOBAL METER CHANGE OVER switch changes the operation of every meter on the console except the comms meters and the record meters. The "normal" meter operation is to monitor pre fader on input channels and post fader on all other signals. When the global meter change over is active the meters change to monitor input amplifiers or bus amplifiers (as appropriate) on all signals. The SOLO TO MONITOR switch connects the solo AFL signals to the monitor system outputs in place of the 2 track return or master left and right signals when ever a solo is active within the console. The SOLO ON / CLEAR switch and indicator has two functions:i. It illuminates when any solo switch (except a master solo switch) is active. ii. When pressed it clears any active solo switches (except master solo switches). The EXTERNAL 1 level control gives continuous adjustment of incoming signals from the first external input and has a range from + 6dB to off.

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.

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.

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.

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’.

CHMIDOUT This option allows the output MIDI Channel to be selected. To set the channel number, press the ‘YES’ button while the display is showing ‘MIDI CH’. The jogwheel can then be used to select the required channel. When the required channel number is displayed, press the ‘YES’ button to enter it.
CHMIDIN This option allows the input MIDI Channel to be selected. This is the channel down which program changes can be sent that the XL4 will respond to when set up in the edit menu, see store menu. To set the channel number, press the ‘YES’ button while the display is showing ‘MIDI CH’. The jogwheel can then 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.

If no scene is present in the location you are trying to store to (displayed in the left hand window) the menu you may access is shown below. STORE –
NEW X-FADE
If a scene has previously been stored in the location you are trying to store to (displayed in the left hand window) Overstore -

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.

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.

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.

Memory menu Memory – Mem Tog Internal External Copy All Clear All
Mem Tog (Memory Toggle) This allows you to swap from the memory you are currently working on to other. For example if you are working on Internal memory mode choosing YES to Mem Tog will switch over to External memory.
Internal This setting sets the system operation to operate with the central control unit’s internal memory.
External This setting sets the system operation to operate with the RAM card memory .
Copy all This function copies the data to and from the RAM card. If INTERNAL memory is active, the data will be copied from internal memory to the RAM card. If EXTERNAL memory is active, the data will be copied from the RAM card to the internal memory.
Clear all This function clears the data in the memory or RAM card. If INTERNAL memory is active, the data will be cleared from internal memory . If EXTERNAL memory is active, the data will be cleared from the RAM card. WARNING! Use this function with care! Although future software releases may feature an UNDO function, the current software does not. Once erased there is no way to retrieve the data unless you have saved it to a RAM card which has been kept somewhere safe.

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.
