13. PC-series power amps

When you open the device sheet for a PC-series device, the "Presets" area, the device sheet, and the "Bird’s Eye view" appear.

Amp PC Sheet

When you double-click a component in the device sheet, the component editor opens.

13.1. "Presets" area

In this area you can store the settings of multiple parameters as a preset, or recall a stored preset to apply its parameters to the current settings. The parameters of the preset that is applied are called the "current parameters."
If you want to recall presets for multiple units simultaneously, click the LinkPresetManagerButton button, and make settings in the "Linked Presets Manager" window .

Amp PC Presets

  • [STORE] button
    This button stores a preset. If you select a preset in which settings have not been stored, the "Store Preset" dialog box appears.

  • [RECALL] button
    This button recalls a preset.

  • [CLEAR] button
    This button clears a preset.

  • Preset list
    This displays a list of the presets. Up to 32 presets can be stored.

    • "Preset"
      Shows the preset number and name. You can expand this and select the parameters that will be recalled.
      If you select a stored preset and double-click this area, you’ll be able to edit the name.
      Empty presets are shown with the name [No Data].

    • "Protect"
      If you click the lock icon ( Amp PC UnProtect ), the icon changes to Amp PC Protect , protecting the preset so that it cannot be edited or cleared.
      If you click the icon in the protected state, protection is removed.

13.1.1. "Store Preset" dialog box

Amp PC Preset

  • [Name]
    Input the name of the preset. By default, this will be "Preset + preset number." You cannot enter a blank preset name.

  • [OK] button
    This stores the preset and closes the dialog box.

  • [Cancel] button
    This cancels the preset store operation, and closes the dialog box.

13.2. "Properties" area

Here we explain the dialog boxes related to the "Properties" area of the "Project" sheet.
An explanation of the item appears below when you click each Property.
Information such as the [Location] and [Device] for the [Display] is not saved as Style information.
For details on device settings, refer to the PC series owner’s manual.

This appears when you double-click a link group on the "Tuning" sheet in which a channel of a PC-series unit is registered, or when you right-click and choose [Open Link Group Editor].

Amp PC LinkGroupW

  • [SOLO] button
    When online, this is enabled if the tool bar’s [Solo Mode] button is on.
    If this is turned on, audio is output only from the channels that are registered to this link group, which is convenient when making final adjustments to the EQ, volume, and delay.

13.3.1. [User EQ/Volume] tab

Here you can make collective adjustments to the User EQ and volume of the channels registered in the group.
Use the Master fader to control the volume.
The "Volume" master fader collectively applies a relative adjustment to the volume of the channels registered in the group.
For details on EQ, refer to "User EQ/User Delay" component editor , and for Volume refer to "Volume" component editor .

Amp PC LinkGroupW

  • [Band Sharing] buttons
    If a channel is registered in multiple groups, click to select the bands owned by each group. An owned band is shown in blue. Bands that are not shown as white numbers on a black background are owned by other groups, and cannot be selected or operated.
    Bands that you click and are colored blue are currently owned.
    Ownership can be relinquished only by the link group editor that owns that band.

  • [MATCHVAL] button
    Copies the EQ settings of bands owned by the link group editor to the registered channels.

  • LINK MASTER
    Applies a relative adjustment to the volumes within the link group.

  • [AMP PROTECT] indicator
    This will light if the protection function of the PC unit itself is operating.

  • [AMP LIMIT] indicator
    This will light if the limiter of the PC unit itself is operating.

    • Master fader
      Applies a relative adjustment to the volumes within the link group. The adjustable range is shown above and below in gray.
      When you right-click the fader and choose [Match Values], the members of the link group are set to the same volume value.

    • Amp PC 3dbUpB button
      Raises the master fader by 3 dB.

    • Amp PC 1dbUpB button
      Raises the master fader by 1 dB.

    • [RESET] button
      Moves the master fader to the 0 position.

    • Amp PC 1dbDownB button
      Lowers the master fader by 1 dB.

    • Amp PC 3dbDownB button
      Lowers the master fader by 3 dB.

13.3.2. [User Delay] tab

Here you can collectively edit the User Delay of the "User EQ/User Delay" component editor for the linked jacks.
For details on delay, refer to "User EQ/User Delay" component editor .

Amp PC LinkGroupW2

  • LINK MASTER
    Here you can apply a relative adjustment to the delay time of the channels of the devices that are registered in this link group.

    • Master fader
      Applies a relative adjustment to the delay times within the link group. The adjustable range is shown above and below in gray.
      When you right-click the fader and choose [Match Values], the members of the link group are set to the same delay time value.

    • Amp PC 3dbUpB button
      Raises the master fader by 3 ms.

    • Amp PC 1dbUpB button
      Raises the master fader by 0.3 ms.

    • [RESET] button
      Moves the master fader to the 0 position.
