Power Amplifier XMS Series

1. Overview

The XMS series is a multi-channel power amplifier ideal for sound systems and commercial spaces. Equipped with a "power sharing" function that allocates power to each channel, this series can efficiently drive a large number of different speaker types. The internal DSP enables mixing, routing, and speaker processing of input signals. Dante models are available and you can build digital systems as well.

2. "Project" sheet

This is the sheet where you place devices. When placing a device, the Settings screen below will appear.

    Select the number of devices to be placed on the sheet.

  • Unit ID Starting From
    You can select the starting number for the Unit IDs of devices.

  • Device Name
    You can view and edit the device name.

3. Speaker connection

You can connect the XMS series to any speaker and view the speaker processor parameters for each speaker. For details, refer to "PC-D and speaker connections" in the PC series documentation.

4. "Properties" area

You can view and edit device information. This section explains "Input Source Redundancy" (Dante model only). For other settings, refer to the XMS series reference manual.

xms proterties
  • Input Source Redundancy
    This setting determines whether the input source for each XMS channel is digital (Dante) or analog.Additionally, when the main line is set to digital, this setting configures the system to switch the input from digital to analog when the digital signal is lost or when an analog audio is detected.

Input Source Redundancy is a function independent of the Dante network’s redundancy function.

① Redundant Mode
You can change the redundancy method for channels 1 to 4 simultaneously.

  • [Off]
    Disables redundancy.

  • [Backup]
    Switches to analog input when the digital input is interrupted due to a problem such as a broken wire.

  • [Override]
    Switches to analog input when analog audio is detected.

② Auto Return
When set to On, the input automatically switches back to digital when the digital line is restored.

③ Ch 1 to 4
Clicking form ten displayed when you click the Value field opens the "Input Source Redundancy" dialog box.

4.1. "Input Source Redundancy" dialog box

② [Auto Return] check box
When this check box is selected, the following applies.

  • In Backup mode
    When the digital input is restored, the input source switches from analog to digital.

  • In Override mode
    When the analog input falls below a threshold, the input source switches back from analog to digital.

"Primary Input Source" area
