Software Installation #

Composer® software provides real-time set-up and control of Composer-Series DSPs, controllers, and endpoints from a Windows PC environment.

  1. Download the Composer software installer from the Symetrix web site (
  2. Double-click on the downloaded file and follow the on-screen directions to install.

After installing the software, refer to the Help File for full connection and configuration information.

Networking PHY Dante Devices #

Devices with a single Dante port don’t have an internal Ethernet switch and the RJ45 jack is connected directly to the Dante Ethernet physical transceiver (PHY). In these cases you must connect the Dante port to an Ethernet switch before connecting to another PHY Dante device to avoid audio dropouts on Dante channels. Dante PHY devices include many Ultimo-based devices and Symetrix hardware: Prism, xIn 4, xOut 4, xIO 4×4, xIO Stage 4×4, xIO Bluetooth, xIO Bluetooth RCA-3.5, xIO XLR-Series.

System Setup #

Successful system setup requires first establishing communications with a Symetrix DSP (e.g., Radius NX, Prism).

Basic Connections

  1. Connect the Control Ethernet port on the DSP to an Ethernet switch with a CAT5e/6 cable. Connect the Dante port on the DSP with a CAT5e/6 cable to the same Ethernet switch for shared Dante and Control networks, or to a different Ethernet switch for separate Dante and Control networks.
  2. Connect the PC running Composer to the Ethernet switch used for Control with a CAT5e/6 cable.
  3. To power a PoE Dante device, connect the Dante port on the device to a PoE-enabled port on the Dante switch. Alternately, connect the Dante port on the device to a PoE injector and then from the PoE injector to the Dante switch.
  4. To power a PoE Control device, connect the Control port on the device to a PoE-enabled port on the Control switch. Alternately, connect the Control port on the device to a PoE injector and then from the PoE injector to the Control switch.

Network Setup #

About DHCP

Symetrix network-enabled devices boot with DHCP enabled by default. When connected to a network, they will look for a DHCP server to obtain an IP address. This process may take several minutes. Computers attached to the same network, and getting IP addresses from the same DHCP server will be ready to go. When no DHCP server is present to assign IP addresses, and Windows default network settings are used, the PC will set an IP in the range of 169.254.x.x with a subnet mask of to communicate with the device. This default to an automatic private IP address uses the last four alphanumeric characters of the device’s MAC address (MAC address hex value converted to decimal for IP address) for the ‘x.x’ values. MAC addresses can be found on a sticker on the back of the hardware. Even if the PC’s default settings have been changed, the device will try to establish communications by setting up appropriate routing table entries to reach devices with 169.254.x.x addresses.

Connecting to Device from Host Computer on Same LAN

The Symetrix device and host computer require the following:

  1. IP Address – The unique address of a node on a network
  2. Subnet Mask – Configuration that defines which IP addresses are included in a particular subnet.
  3. Default Gateway (optional) – The IP address of a device that routes traffic from one subnet to another. (This is only needed when the PC and device are on different subnets.)

If you are putting a device on an existing network, a network administrator should provide the above information or it may have been provided automatically by a DHCP server. For security reasons, it may not be recommended to put AV system devices directly on the Internet. If you do, a network administrator or your Internet Service Provider can provide the above information.

If you are on your own private network, directly or indirectly connected to the device, you may allow it to choose an automatic IP address or you may choose to assign it a static IP address. If you are building your own separate network with static assigned addresses, you may consider using an IP address from one of the ”Private-Use” networks noted in RFC-1918:

  • = IP addresses through and a subnet mask of
  • = IP addresses through and a subnet mask of
  • = IP addresses through and a subnet mask of

Configuring IP Parameters #

Locating Hardware

Discover and connect to device hardware with the Composer Locate Hardware dialog (found in Hardware menu), or click the Locate Hardware icon in the tool bar, or on a particular unit icon. Composer directly locates DSPs and control devices. Dante devices are located by an already located, and online, DSP in the Site File.

IP Configuration with Composer®

The Composer Locate Hardware dialog will scan the network and list available components. Select the unit you wish to assign an IP address to and click the Properties button. If you wish to assign the device a static IP address, select “Use the following IP address” and enter the appropriate IP address, subnet mask and gateway. Click OK when finished. Now, back in the locate hardware dialog, ensure the device is selected and click “Select Hardware Unit” to use this hardware in your Site File. Close the Locate Hardware dialog.

Reset Switch

To be used under the supervision of technical support, the device has the ability to reset its network configuration and completely revert to factory defaults. Locate the reset switch using the illustrations in this guide and/or the product data sheet.

  1. Short press and release: Resets network configuration, returns to DHCP.
  2. Apply power while holding, release after unit boots then reboots: Factory resets unit.
