xIO Expanders – xIn 4, xOut 4, xIO 4×4 #

  • How do I configure the xIn 4, xIO 4×4 and xOut 4?

    The xIn 4, xIO 4×4 and xOut 4 are configured via the award winning SymNet Composer software. Once transmit and receive flows are created within the software the xIO 4×4, xIn 4 and xOut 4 will need to be located through a Radius or Edge DSP, then the configuration pushed to the hardware.

  • Can the xIn 4, xOut 4, and xIO 4×4 be used with non-Symetrix DSP systems?

    Yes. You can use any of 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.

    • Input sensitivity = +4dBu
    • Pantom power = Off
  • Do the xIn 4, xIO 4×4 and xOut 4 need to be connected to a Gigabit network?

    No- The xIn 4, xIO 4×4 and xOut 4 have a 100 Base-T Ethernet port that provides 8 (4×4) channels of Dante network audio, Ethernet communications, and power. Symetrix suggests connecting to a gigabit switch. Especially if multiple devices with Dante audio are connecting to a common switch.

  • How do I power up the xIn 4, xIO 4×4 and xOut 4?

    The xIn 4, xIO 4×4 and xOut 4 are powered over Ethernet (PoE) by an IEEE 802.3af Class 0 standard compliant switch or the included injector. No other external power supply is needed or used.

  • Can I send more than 4 channels of Dante networked audio to and from the xIn 4, xIO 4×4 and xOut 4?

    No- The xIn 4, xIO 4×4 and xOut 4 Dante Interface I/O interface is based upon the Audinate Ultimo chip that supports 4×4 channels of Dante networked audio.

  • Is there and under the table or surface mount option for the xIn 4, xIO 4×4 and xOut 4?

    Yes- Under Table/Surface Mount Kits consists of a U-shaped bracket and two mounting screws. With this kit, a single unit can be secured under a table or to another flat surface as required. (Mounting solutions sold separately).

  • Does the xIn 4, xIO 4×4 and xOut 4 have a rack mount option?

    Yes- The Rack Mount Kits consists of a rack tray and four mounting screws. With this kit, one or two units can be mounted side-by-side in a single rack space. (Mounting solutions sold separately).

  • How do I configure the xIn 4, xIO 4×4 and xOut 4?

    The xIn 4, xIO 4×4 and xOut 4 are configured via the award winning SymNet Composer software. Once transmit and receive flows are created within the software the xIO 4×4, xIn 4 and xOut 4 will need to be located through a Radius or Edge DSP, then the configuration pushed to the hardware. In later versions of Composer there is an intelligent module available in the Tool Kit for configuration that can also be used for external control.

  • Are the xIn 4 and xIO 4×4 capable of providing Phantom Power?

    Yes- The xIn 4 and xIO 4×4 have (4) balanced analog audio inputs, with individually software-controllable pre-amp gains (reference levels of -50 dBu, -40 dBu, -20 dBu, -10 dBV and +4 dBu), phantom power (+48 VDC ), and mute.

  • Does the xIn 4, xIO 4×4 and xOut 4 have redundant capabilities?

    No- The xIn 4, xIO 4×4 and xOut 4 are based upon Audinate’s Ultimo Dante chip which does not have a redundant mode. They should be connected to the primary Dante network. Other standard IT practices of network redundancy can be employed instead.

  • Can I daisy-chain multiple xIn 4, xIO 4×4 and xOut 4 together?

    No- The xIn 4, xIO 4×4 and xOut 4 have a single Dante port and Power over Ethernet (PoE) cannot be daisy-chained. They can be directly connected to the main DSP (via a PoE injector), but not to each other.

  • Can the xIn 4, xIO 4×4 and xOut 4 be used as standalone DSP devices?

    No- The xIn4, xIO 4×4 and xOut 4 are part of a series of I/O expansion products for the Symetrix DSP products (Edge and Radius) using Dante network audio.

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.
