Power Amplifiers: XMV-series

18. Power Amplifiers: XMV-series

18.1. Overview

The XMV series is a Class D power amplifier that offers high efficiency while also incorporating functions optimized for commercial spaces. In addition to analog inputs and outputs, the system is equipped with the newly developed "YDIF" digital audio format or "Dante" network audio. The YDIF-compatible models that are connected using Ethernet cables simplify setup, while the Dante models enable high-quality digital transmission in large-scale facilities.

18.2. "Project" sheet

When placing devices, the Settings screen shown below will be displayed.

Number of Devices
Selects the number of XMV series units placed on the sheet.
Unit ID Starting From
You can select the starting number for the device Unit IDs.
Device Name
The device name can be displayed and edited.

18.2.1. "Properties" area

"Input Source ＆ Redundancy"

Here you can specify for each channel whether the input source to the XMV will be digital or analog. If the input source is specified as digital, you can specify that the input source will switch from digital to analog when a pilot tone or analog input is detected. Here we explain the screen for when the digital input is Dante.
When you click on the Value field for each channel in the Properties Area "Input Source＆Redundancy," and then click the "…" that is displayed, the "Input Source & Redundancy" dialog will be displayed.

[Redundant Mode] list box
Selects the redundancy method.
- [Off]
  Redundancy is disabled.
- [Backup]
  Switch to analog input when the pilot tone of the digital input is interrupted due to a broken connection or other problem.
- [Override]
  Switch to the analog input when analog audio is detected.
[Auto Return] check box
If this check box is selected, operation will be as follows.
- In the case of Backup mode
  When the digital input recovers, the input source is switched from analog to digital.
- In the case of Override mode
  When the analog input falls below the threshold value, the input source is returned from analog to digital.
Channel index
Shows the input channel number for which to make settings.
"Primary Input Source" area
Here you can specify for each channel whether the input will be digital or analog.
- [YDIF (Digital)]/[Dante (Digital)] option button
  The signal of the corresponding channel is taken from YDIF or Dante.
  To specify the Dante patching, make settings in Dante Controller.
- [Active Redundant Mode] check box
  If this check box is selected, the redundancy function is enabled.
  The [Redundant Mode] list box determines the redundancy mode. If [Off] is selected, the redundancy function is disabled even if this check box is selected.
- [Analog] option button
  The signal is taken from the analog input jack of the corresponding channel.
"Redundant Mode - Backup" area
Here you can specify how the pilot tone is detected for each channel.
- [Frequency] spin box
  Specifies the center frequency of the pilot tone.
- [Detection Threshold] spin box
  Specifies the input level threshold value for the pilot tone. Input that exceeds the threshold value is considered to be the pilot tone.
  - [Detection Time] spin box
    Specifies the detection time for the pilot tone. If the pilot tone can not be detected for the specified time interval, it is determined that the input has ceased.
  - [Notch Filter] check box
    If this check box is selected, a notch filter is enabled to eliminate the frequency component of the pilot tone so that the pilot tone is not output from the amp.
- [Q] spin box
  Specifies the width of the frequency band for the notch filter.
"Redundant Mode - Override" area
Here you can specify the conditions under which each channel will switch to the analog input in Override mode.
- [Override Threshold] spin box
  Specifies the threshold value for the analog input. When the threshold value is exceeded, the input source will switch to analog.
- [Auto Return Delay] spin box
  If the [Auto Return] check box is selected, this specifies the time after the analog input falls below the threshold value until the input is switched back to the digital input.
[Save Changes] button
Saves the settings and closes the dialog box.
[Cancel] button
Discards the changes and closes the dialog box.
