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.  

xIO General

  • What is the maximum number of xIO devices allowed in a system?

    Control Devices – Composer Limits

    The maximum number of control devices in a Site File is 128. This includes DSPs, Touchscreens, W-series, Control Servers, and xControls. The limit is based on the maximum number of units Composer can communicate with at once. If this limit is exceeded, some will not locate correctly so Composer will not go online. This limit does not include Dante-only devices that are located through a DSP. See the section below for limits on these devices.

    Dante Devices – Dante Audio Routing Limits

    The maximum number of Dante devices that can be routed to by one Brooklyn-based DSP is 128. But in reality, this limit is rarely met as there are other soft limits that are reached first. First, the maximum number of Dante Channels (64) and/or Dante Flows (32) supported by one DSP will usually limit the number of devices that can be used.

    Dante Devices – Intelligent Module Limits

    The CPU/Memory resources used by Intelligent Modules will also limit the real-world number of devices that can be used. The maximum number of 256 Intelligent Modules per DSP may theoretically come into play, but other practical limits will almost always be reached first. For xIO devices, Intelligent Module requirements for CPU processing limit is different for Radius NX class DSPs and Edge/Prism class DSPs. Radius NX devices can support about 30 Intelligent Modules communicating with xIO devices. Alternately, Edge/Prism class DSPs, which have an older CPU and less memory, can support about 20 Intelligent Modules communicating with xIO devices. This is a rough estimate because the available processing is also affected by other things the Site might be doing (eg, running Control Screens, recording/playback, etc). In practice, this means that if you want to run more than 20 or 30 xIO devices in a single Site, you will need to divide them between multiple DSPs.
