Each of the 136 patterns can cons

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) Se

28、lect 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 Multip

29、le Scene Mode (switch E not depressed),the Sequence Scene will be automatically selected for editing.If a dif- ferent 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

30、 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

31、 its associated switch (H), or, if Sequence 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.NOT

34、ual 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 wil

35、l begin to blink,indicating that the system is in Edit Preview Mode. 2) Select Sequenced Scenes by pressing the Sequence Scene (G) button; it will illu- minate. 3) Scroll to the Scene to be copied using the Up/Down (A) keys to change the Display (B). 4) Hold down the Sequence Scene button.The displa

36、y will show Cpy?. 5) Still holding down the Sequence 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 s

37、elect 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

38、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 function to transfer those patterns into the Manual Mutes.You can

39、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 memory.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 c

40、hannels un-muted ( you already have a way to start a Scene with all channels un-muted, you can hold down the Edit Safe button to clear all mutes in a Scene when editing). p.59 Microprocessor control 4 mute control panel typical input or output MUTE PK 6 0 SIG +8 SAFE PREVIEW J K L SEQUENCE SCENE ON

42、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 channel 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.Onc

43、e 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

44、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

45、 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,indi- cating that the system is in Edit Safe Mode. 2) Select a channel to safe: Pressing the Mute Sw

46、(K) of a channel will assign/de- assign a channel to the Safe Scene.The status LED (J) of any channel 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 immediately un-mute it. 3) Clearing the Safe Scene: If you wi

47、sh 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 button down until the display shows CLRD.All channels assigned to the Safe Scene will be de-assigned and you can start fresh.

48、 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 (s

49、tatus 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
