17. Power Amplifiers PC-series

17.1. Overview

By combining the powerful 20×8 input matrix functions of the PC-D/DI series amplifiers with Dante I/O, the versatility of any system can be dramatically increased.
Not only can the PC-D/DI’s input matrix function be an auxiliary matrix that expands the entire system, but by allowing direct audio signal input from other analog devices or Dante-equipped devices even in systems without additional mixers or DSPs, even more flexible routing becomes possible.

17.2. "Project" sheet

This is the sheet on which devices are placed. When placing devices, the Settings screen shown below is displayed.

The Speaker Editor allows you to control the parameters of the power amplifier from which you are connecting.
For details, refer to "Speaker Editor / Multi Speaker Editor."

17.2.2. Speaker Editor / Multiple Speaker Editor

When a speaker is connected to a PC-series device via a wire, the parameters of the PC-series device’s speaker processor are shown for each individual speaker.
When you double-click a speaker or right-click and choose [Open Speaker Editor] from the context menu, the Speaker Editor opens.
When multiple speakers are selected, you can right-click and choose [Open Multiple Speaker Editor] from the context menu to open the Multiple Speaker Editor.
This is convenient in the following situations.

  • When speakers are connected to multiple PC-series devices, and you want to view each of these speaker processors in a single step.

  • When you want to view the superimposed response curves of the Main and Sub speakers. (Multiple Speaker Editor)

For details on the parameters, refer to "Speaker Processor" component editor of the "ProVisionaire Design Component Guide" .

17.2.3. Properties Area

This area allows you to display and edit device information. The following section explains “Input Source Redundancy”.For other settings, refer to the PC series instruction manual.

pc properties

Input Source Redundancy
The PC series has two redundancy modes: "Backup Mode" and "Override Mode".

Input Source Redundancy is a function that is independent from the Dante network redundancy function.
  • Redundant Mode

    • Backup
      If the input audio on a primary line (Dante 1 to 4) is cut off due to a problem such as an input device failure, the line will automatically switch to the backup line (Dante 13 to 16, Analog 1 to 4).

    • Override
      When audio input from a backup line (Dante 13 to 16, Analog 1 to 4) is detected, the detected signal will automatically interrupt the audio on the primary line (Dante 1 to 4). This allows for broadcast interruptions, such as high-priority emergency broadcasts and site-wide announcements.

      In either mode, the backup lines can be set up in two tiers, and the channel combinations are fixed.

      PRIMARY SOURCE 2nd SOURCE 3rd SOURCE

  • Auto Return

    • In Backup Mode
      When this option is turned on, the input source will automatically switch back to the primary line when the primary line is restored.

    • In Override Mode
      When this option is turned on, the input source will automatically switch back to the primary line when the audio from the backup line falls below the threshold.

  • Dante 1 to 4

    pc input source redundancy
    • Input Source checkbox
      Set whether to enable (on) or disable (off) the backup lines at each tier. The backup lines can be set up in two tiers, and the channel combinations are fixed.

    • Override Threshold
      For Override Mode, set the input level threshold for each channel to determine whether an interrupting input signal is present.

    • Auto Return Delay
      When Auto Return is turned on in Override Mode, set the time from when the interrupt input signal ends until the line switches back to the primary line.

17.3. "Tuning" sheet

The Tuning sheet allows you to set parameters (such as EQ and Delay) for grouped channels collectively.
For the sheet details, please refer to the "Tuning" sheet .

This is the parameter setting screen for link groups.
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.

17.3.2. [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.
