  • Updating Symetrix Bluetooth Endpoint Firmware from 8.5.2 to 8.5.3 and beyond

    On January 17, 2024 the Symetrix Engineering Team discovered a complication when testing a pre-release version of Composer and firmware for xIO Bluetooth and xIO Blutooth RCA. The issue has been addressed and fully tested in the latest Composer release (8.5.3). Unfortunately for systems running the latest Bluetooth firmware from Composer 8.5.2, the next upgrade will require a one-time, customized procedure.  

    Issue Description: 

    When attempting to upgrade/downgrade from xIO Bluetooth Firmware 2.29, Composer will report a successful update, but will then report that the xIO Bluetooth device needs updating again. This process can be repeated but the xIO Bluetooth upgrade will never actually be successful. 

    To upgrade/downgrade from Composer 8.5.2 (xIO Bluetooth Firmware 2.29):  

    1. Factory reset each Symetrix Bluetooth device by physically holding the side-mounted reset button with a flat head screwdriver when connecting the Ethernet cable.  
    2. The device will perform a factory reset which will then let it properly accept an update to the next firmware version 2.31 found in Composer 8.5.3.  

    We apologize for the inconvenience and are available by phone and email to assist any customer with this procedure.

  • Can I change the default PIN on my xIO Bluetooth?

    Yes! In Composer, with the xIO Bluetooth located, you can change the PIN number through the unit's Intelligent Module. If online with Composer or Connected Offline with the Intelligent Module, the PIN will update live once entered into the PIN field. It is still a good idea to then re-push the file to system to update the archive in the DSP.

  • Can I use xIO Bluetooth devices with non-Symetrix DSP systems?

    Yes. You can use any Symetrix Dante expander units with third party DSPs and systems. However, these devices will not be configurable beyond what Dante control allows, and will remain in their default settings.

    • The front panel pairing button is the only way to initiate pairing.
    • Audio bridging mode is Media ONly
    • Connection mode is Single, which only allows one device to pair at a time and device are not remembered.
    • Sleep Mode is enabled and set to 60 seconds
    • Default PIN is 0000
    • Analog inputs are RCA
    • Device name is “xIO-Bluetooth-[#]” or “xIO-Bluetooth-RCA-3-5-[#]”. Network name can be edited in Dante Controller, but may not change display name with pairing – this may require Composer.

  • 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.
