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.

Number of Devices
Selects the number of PC series units placed on the sheet.
Unit ID Starting From

Device Name
The device name can be displayed and edited.

17.2.1. PC-D and speaker connections

If you drag and drop speakers from the Devices area, any speaker can be added to the Project sheet.

When you connect an amp and speaker, and double click on the speaker, the Speaker Editor 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. "Properties" area

Refer to the PC series owner’s manual for information about device settings.

17.2.3. Speaker Editor / Multiple Speaker Editor

  Specifies the upper threshold of impedance that is measured. If the specified value is exceeded, it is determined that the speaker has malfunctioned, and the indicator will light.
  If the specified value is exceeded, it might be that the connection is open, such as due to a broken cable.
- IMPEDANCE [Low Threshold] knob/indicator
  Specifies the lower threshold of impedance that is measured. If the measurement drops below the specified value, it is determined that the speaker has malfunctioned, and the indicator will light.
  If the measurement drops below the specified value, it might be that the resistance has dropped due to a shorted coil, etc.

17.8.6. "Speaker Out" component editor

This shows the speaker output jack’s output voltage and output current.

[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.
[PEAK LIMIT] indicator
This is lit if the peak limiter within the speaker processor of the PC unit is operating.
[RMS LIMIT] indicator
This is lit if the RMS limiter within the speaker processor of the PC unit is operating.
[Voltage] meter
Shows the output voltage as Peak and RMS.
[Current] meter
Shows the output current as Peak and RMS.
