Sound-Quality

These wall-mounted, mic/line, Dante-enabled endpoints include an ultra-high performance audio signal path utilizing the same studio-grade mic preamps and AD/DA signal chain as our top-of-the-line DSP. The result is best-in-class clarity, intelligibility, and accuracy that maximizes performance of the entire system. 

Customizable LED Indicators

A front-panel RGB LED for each connector can be programmed to reflect any system parameter such as signal presence, clip, mute, or preset. Or they can easily be blacked-out.

Unmatched Design and Construction

We agonized over every detail to create a truly professional solution for the most demanding projects. A raised bezel and proprietary thumb notch ease connector attachment and removal. The vertically oriented network port is accompanied by an integrated stress-release attachment point and the elegant Decora-compatible faceplate snaps into place without visible screws.


Each xIO XLR is rugged to the core, constructed of die-cast zinc. The design incorporates a unique XLR mounting method that protects internal components and electronics.

Sleek Control Buttons

Integrated buttons are flush with the faceplate and can control any function of the system.


In combination, the bright indicators and control buttons allow for rapid, on-site diagnostics and management of a system.

Flexible and Simple Deployment

The product is available in four models that can be matched to any need, simplify set-up, and deliver a sophisticated look and feel in premium light and dark finishes.

Frequently Asked Questions

xIO XLR-Series

  • What are the xIO XLR properties?

    All xIO XLR devices have three device specific properties available in the properties window. 

    • Normal LED Function– Specifies the normal function of the LEDs. 
      • Control Pin – The Intelligent Module control pin inputs are used to set the LED colors and brightness. The incoming value is sampled every 0.5 and applied to the LEDs. The incoming values is shown in the Intelligent Module UI as well. 
      • Off – The LEDs are off 
      • Phantom Power – The LEDs show Phantom Power operation for the corresponding XLR 
        • Amber – Phantom Power is on 
        • Off – Phantom Power is off 
      • Signal Level – The LEDs show Signal/Clip information for the corresponding XLR 
        • Red – The signal is clipping 
        • Green – The signal is present 
        • Off – No signal is present 
    • Button Press Function – Controls what happens when pressing and releasing the button on the unit. Two gang devices have two buttons but both are programmed to react the same 
      • Flashlight – The LEDs will temporarily light white to light a dark area until the button is pressed again or after 10 seconds elapses, when they will return to configured normal operation. 
      • Phantom/Level Toggle – The LEDs will first temporarily show the Phantom Power status as described above. After a second press, the LEDs will them temporarily show the Signal Level as described above. After a third press or after 10 seconds elapses, when they will return to configured normal operation. 
      • Control Pins – The LEDs will temporarily light with the values from the Control Pins as described above until the button is pressed again or after 10 seconds elapses, when they will return to configured normal
        operation. 
      • Disabled – The front panel button does nothing when pressed. 
    • Button Hold Function – Controls what happens when pressing AND holding the button on the unit for some amount of time and then releasing. Two gang devices have two buttons but both are programmed to react the same. 
      • Disabled – Pressing and holding has no function. 
      • Reset – depending on the amount of time the button is held before releasing, one of the following functions will occur with a unique LED pattern shown for each option. 
        • 3 seconds – the unit will reboot. This is indicated by a purple flashing sequence occurring once after 3 seconds. 
        • 10 seconds – the unit will reset the IP settings and reboot. This is indicated by a purple flashing sequence beginning again after 10 seconds and then continuing until 20 seconds is reached. 
        • 20 seconds – the unit will reset to factory defaults and reboot. This is indicated by the LEDs stopping flashing and turning solid purple when 20 seconds is reached.. 
  • My xIO XLR’s LEDs flash while booting up, but then go dark shortly after.

    This is normal function of the xIO XLR. Its default configuration for the LEDs is "control pins" which themselves will be disconnected/unconfigured from the factory. You can set these in the Composer Intelligent Module. Refer to this Tech Tip for more information.

  • What IO configurations are supported?

    The product is available in four models. Two single-gang configurations offer either one input and one output (1×1), or two inputs (2×0). Two double-gang configurations offer either two inputs and two outputs (2×2) or four inputs (4×0). 

  • What is the construction material used?

    The xIO XLR Series uses die cast zinc for the front bezel, faceplate, and rear housing.

  • Are EU form factors available for all models?

    Single-gang models will support EU form factors but not double-gang models. There is just too much good stuff to fit in a EU double-gang box!

  • Can I customize or disable the front LED’s?

    Yes, using Composer, the LED’s can reflect any system parameter such as signal presence, clip, mute, or preset. Or they can easily be blacked-out. 

  • What can be controlled with the front button?

    Pretty much anything! The front button can be used to momentarlly show LED statuses and is associated with a logic output in the Intelligent Module for the xIO XLR. This logic output can be used for any control function in Composer. This button can also be disabled.

  • Can the xIO XLR be used with other manufacturer’s DSPs?

     Yes it can. The xIO XLR is a standard Dante endpoint. Composer is required for initial configuration and a Symetrix DSP is required for realtime control if desired. Composer version 8.5 and later include the xIO Updater/Configurator which takes the place of needing to have Symetrix DSP in the system to connect to and control our Dante devices. Previous Composer versions will still need a Symetrix DSP.

  • Does the xIO XLR use POE or POE+?

    The xIO XLR-Series uses POE.

  • Does the xIO XLR support Dante and AES 67?

    Yes, the xIO XLR supports Dante and AES 67.

  • Does the xIO XLR support network redundancy?

    No, the xIO XLR has a single Dante/control network RJ45 port so it cannot support Dante redundancy.

  • What is the minimum latency the xIO XLR will operate?

    The minimum Dante latency setting is 1ms.

  • What sample rate does the xIO XLR operate?

    The xIO XLR-Series supports 48 and 96 kHz. 

  • Why does the xIO XLR support a 96khz sample rate if the Symetrix DSP line only supports 48kHz?

    We at Symetrix know customers will find this to be a craft product they will want to use in various installs, whether old or new. If those installs have Symetrix equipment then great; if it is a different system we still want to provide the highest quality option possible with the most flexibility.
