If the Mute Sw (K) is pressed once, the local mute will be cleared, but no apparent change will occur.The Mute LED (L) will still be lit, and the Status LED (J) will still be steady Red.At this point there is only one source telling the channel to mute; the Mute Scene. If the Mute Scene is then disabled, the channel will un-mute because the Local Mute was previously cleared.The user should be aware of this fact:The Local Mutes can toggle invisibly behind a Mute Scene. For an even number of presses on the Mute Sw (K), the Local Mute will return to its origi- nal state, an odd number of presses will change the Local Mute to its opposite state. Each press of this switch increments the Sequenced Mutes by one, the display (B) will reflect this.Also used to activate the displayed Scene when an Up/Down (A) button was used to scroll to a new Scene. In this case, an * will be displayed as the first character in the display to indicate that the displayed number is not currently the active Scene. Pressing Recall will put that displayed Scene into place and clear the * from the display. NOTE:All of the above actions will take place, but the displayed Sequenced Scene will not be active (mutes not enabled) unless the Micro Scene switch (G) is lit. Each press of these switches increments or decrements the Patch Display (B). Holding either button down will allow quickly scrolling up or down.The buttons are also used to select the parameters and settings of the system while in Utility mode. X-VCA owners manual 6 microprocessor control p.96 mute control panel typical input or output p.97 microprocessor control6 mute scenes There are 9 possible Scene sources: Manual Mute Scenes 1 thru 8, and the Micro Scene.The Micro Scene button (G) is the enable switch for the 128 possible Sequenced Scenes.The 8 Manual Mutes are totally independent of the 128 Sequenced Scenes, giving the system a total of 136 possible mute patterns. Each of the 136 patterns can consist of any combination of Channel and Output mutes, all of the 9 possible sources can be combined to create additional patterns. Creating a Mute Scene (or Editing an existing one): 1) Press the Edit Preview button (C), it will begin to blink, indicating that the system is in Edit Preview Mode. 2) Select a Scene to Edit:The system will automatically choose a Scene to edit, depending on the status of the system when Edit Preview was selected. If the system was in Single Scene Mode (switch E depressed), the Mute Scene that was currently active will be selected to edit. If the system was in Multiple Scene Mode (switch E not depressed), the Micro Scene will be automatically selected for editing. If a different Scene than the default is to be edited, that scene should now be chosen by pressing 1 of the 9 possible Mute Scene buttons (G continue to hold the button down until the display shows CLRD.All channels assigned to that Scene will be de-assigned and you can start fresh. 6) Saving your edit: Once you have a Scene configured the way you want it, either press the blinking Edit Preview (C) button to exit Edit Mode and return to Normal Mode, or select another Scene to edit by pressing its associated switch (H), or, if Micro Scene was selected, press the Up/Down (A) keys to select a new Patch to edit.There is no STORE button to press, the changes take place immediately while editing, and the Scene is saved automatically when a new Scene is selected or upon exiting Edit mode. NOTE:This immediate change will be most apparent when editing a scene that is currently the active scene (the Mute Scene that was ON when you entered Edit mode).The Mute LED (L) will change along with the Status LED (J) as a channel is added or removed from the scene during editing. p.98 X-VCA owners manual 6 microprocessor control mute control panel typical input or output p.99 microprocessor control6 copying a mute scene Copying a Mute Scene: Mute Scenes can be copied from a Sequenced Scene (Patch) to a Manual Mute Scene. Manual Mutes cannot be copied to Sequenced Scenes or to each other.To copy a Sequenced Scene into a Manual Mute Scene, follow the steps outlined below. 1) Press the Edit Preview button (C), it will begin to blink, indicating that the system is in Edit Preview Mode. 2) Select Sequenced Scenes by pressing the Micro Scene (G) button; it will illuminate. 3) Scroll to the Scene to be copied using the Up/Down (A) keys to change the Display (B). 4) Hold down the Micro Scene button.The display will show Cpy?. 5) Still holding down the Micro Scene button (G), now also press the desired Manual Mute switch (H).The display will show Copy, and the Sequenced Scene Mute pattern is copied to the target Manual Mute, over- writing whatever pattern may have originally been there. 6) You can now select the newly created Manual Mute Scene for editing by pressing its select switch (G).The copied Mute pattern will be there, you can use that as a starting point for your edits. 7) Exit back to Normal mode when youre done by pressing Edit Preview (C) again. NOTE:You can use this copy feature as a way to Back-up your Manual Mute Scenes, even though you cant copy from Manual Mutes to any other Mutes. Instead, use the highest numbered Patches (120 to 127) to create the original versions of your Manual Mute Scenes.Then use the copy func- tion to transfer those patterns into the Manual Mutes.You can always go back to the originals (120 to 127) and re-load (copy) them into the Manual Mutes whenever needed.You can also use Patch 128 as an All Mute memo- ry. Program it with all channels muted, you can then copy it to a Manual Mute when you need to start a Scene with all channels muted instead of all channels un-muted ( you already have a way to start a Scene with all chan- nels un-muted, you can hold down the Edit Safe button to clear all mutes in a Scene when editing). p.100 X-VCA owners manual 6 microprocessor control mute control panel typical input or output p.101 microprocessor control6 The Safe Scene There may be occasions when a channel needs to be made Safe from all pro- grammed mutes.This may occur during a show when an on-stage microphone needs to be used as an announce mic, or a switch-over has to be made to a backup chan- nel due to some technical difficulty.The Safe Scene allows a channel to be removed from the control of all Mute Scenes without having to edit any of the scenes. Once a channel is assigned to the Safe Scene, it will ignore all Mute Scene commands.The Mute Scenes themselves are not altered, its only the channels response that has been changed.This allows temporary changes to be made to a show, due to nightly needs, without having to go in and edit the programmed scenes.Youll probably need the original scenes, as is, the next time the show is performed. NOTE:The Local mute command is not affected by this Safe, the Local mute is always effective. The Safe Scene is always active, if a channel is assigned to the Safe Scene, it will ignore any mute commands from a Mute Scene.The Status LED (J) of a channel will be a steady Green color if a channel is Safe. Editing the Safe Scene: 1) Enter Edit Safe Mode: Press the Edit Safe button (D), it will begin to blink, indicating that the system is in Edit Safe Mode. 2) Select a channel to safe: Pressing the Mute Sw (K) of a channel will assign/de-assign a channel to the Safe Scene.The status LED (J) of any chan- nel assigned to the Safe Scene will blink Green. If a channel is currently muted because of a Mute Scene, assigning it to the Safe Scene will immedi- ately un-mute it. 3) Clearing the Safe Scene: If you wish to clear all assigned channels from the Safe Scene, press and hold the Edit Preview (C) button.After a second or two, the display will change to CLR?. Continue to hold the but- ton down until the display shows CLRD.All channels assigned to the Safe Scene will be de-assigned and you can start fresh. 4) Exit Edit Safe Mode: Press the blinking Edit Safe button (D) again. It will stop blinking and the system will return to Normal mode.Any blinking Green status LEDs will turn to steady Green indicating that the channel is in Safe mode. If a channel was previously being muted by only a Mute Scene (status LED was steady Red), but is now Safe, the status LED will show steady Green and the Mute LED (L) will be off. If the channel was being muted by a Local mute, it will remain muted.The Safe Scene does not affect Local Mutes. NOTE:Assigning a channel to the Safe Scene can be done quickly if an emergency arises and a programmed channel has to be un-muted. Its a simple 3 step process: 1) Press the Edit Safe Sw to enter Edit Safe mode 2) Press the Mute Sw of the desired channel- The channel will un-muted at this point. 3) Press the Edit Safe Sw again to return to Normal mode p.102 X-VCA owners manual 6 microprocessor control mute control panel typical input or output Utilities The Mute Controller has a number of parameters that the user can change.A Utility Mode is provided for accessing these settings.The following is a current list of para- meters, along with their default and other possible settings.The default setting is shown UNDERLINED.An explanation follows on how to review or change the dif- ferent settings. DisplayMeaningSettings uPMicro ProcessorON or OFF Determines whether the Mute System is ON or OFF.When OFF, the entire Mute Scene system is disabled, only the Local mutes will operate.This setting can be used if Traditional console operation is desired (i.e. No programmed scenes are want- ed). M ChMIDI Channel01 to 16 Sets the MIDI channel that the Controller uses to communicate to the MIDI world. The Mute Controller can send and receive MIDI Program changes, MIDI dumps etc. It does so on this channel. LockEdit LockOFF or ON If set to ON, prevents any changes to be made to any Mute Scene. If Edit Preview is pressed when LOCK is ON, Lock is displayed and the system will not enter Edit Mode. Dmp?MIDI Dump When activated, the contents of all the Mute Scenes are transmitted via the MIDI Out jack using SysEx protocol.A librarian or archiving MIDI program can be used to store the Mute settings externally. Note: Loading of external data via SysEx com- mand is always active. BaseMIDI Base01 or 00 There are 128 possible MIDI numbers. Do you want to start counting at 01 and count up to 128, or start at 00 and count up to 127 ? Different MIDI devices do it either way.You get to choose. ExtExternal CtrlOFF or ON Normally, the Mute System uses its internal Mute Scenes to control the Console mutes.Alternately, MIDI Note Commands can be used to control the channel mutes directly.When Ext is ON, the Display(B) will show Ext, and the normal Mute Scenes will be disabled.The Controller will now respond only to externally received Note On/Off commands (via MIDI In jack). PgmProgram ChgON or OFF The Mute Controller normally sends a MIDI Program change command every time the RECALL (I) button is pressed, corresponding to the Patch number shown in the Display.Also, if a MIDI Pgm Chg is received, the Controller will respond by recalling the Patch Mute matching that Pgm Chng. Setting Pgm to OFF disables the sending and receiving of MIDI Pgm Changes. p.103 microprocessor control6 p.104 X-VCA owners manual 6 microprocessor control mute control panel typical input or output Changing and reviewing the utility changes The Utility settings can be accessed by entering Utility Mode. Once there, the differ- ent parameters can be changed to suit users preferences.The changes stay in effect until they are again modified by the user, or a System Reset is performed (detailed later) which changes them all back to their default settings. Utility Mode: 1) Enter Utility Mode: Press the Micro Utility button (F), it is a latching switch, and the system will stay in Utility Mode while this button is depressed.The Display (B) now shows the first Parameter - uP of the Parameter List. 2) Select a Parameter to edit: Use the Up/Down keys (A) to scroll thru the list of available Parameters. 3) View the current Setting: Press the Recall (I) button.The Display will change from showing the Parameter to showing the Parameters current setting. 4) Changing the setting:While the Display is showing Parameter Settings (not the Parameter itself), the Up/Down keys will scroll thru the list of possible settings for that Parameter. Use the keys to select the new set- ting and press the Recall button again.The Display will briefly show * , the displayed setting will be activated and the Display will go back to show- ing the Parameter. Note:The only way to get back to showing the Parameter is to press the Recall button, so even if no change is desired, the Recall button must be pressed. Make sure the display is showing the desired setting when you press Recall.You are now back at Step 2, and can continue to select and change Parameters. 5) Exit Utility Mode: Once youre done, press and release the Micro Utility (F) key, the Mute System returns to Normal Mode with the new set- tings in place. p.105 microprocessor control6 p.106 X-VCA owners manual vca facilities 7 Inputs and outputs LCR 1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 PK SIG L R MUTE VCA 1 MUTE VCA 2 M L-R PAN ON GROUPS M L-R BAL ON GROUPS PK 6 0 SIG +8 5 10 0 5 10 20 30 15 50 40 SOLO VCA ASSIGN 5 10 0 5 10 20 30 15 50 40 SOLO VCA ASSIGN 5 10 0 5 10 20 30 15 50 40 UNITY VCA 1 SOLO ASSIGN EDIT VCA 1 ASSIGN 5 10 0 5 10 20 30 15 50 40 UNITY VCA 2 SOLO ASSIGN EDIT VCA 2 ASSIGN micro control panel SINGLE SCENE EDIT PREVIEW MICRO UTILITY EDIT SAFE HEADPHONE AND TALKBACK JACKS LOCATE
