Optimizing Networked Audio with Symetrix Composer and Dante-enabled Devices

The videos on this page are part of the Symetrix training program of the same name. If you have already completed your Composer certification, you can utilize these videos to catch up on the latest products and techniques. If you have not yet earned your certificate, please access this content through our online training center.

The learning objectives for this chapter are:

  • Explore the embedded Dante network interface included with Symetrix’s Dante-enabled DSP.
  • Describe the uses for Symetrix analog I/O expanders
  • Be able to create receive and transmit busses for Dante and AES67 network audio signals using Composer
  • Control supported third-party AV devices on a Dante network
  • Explain AES67, where it is supported, and when it should be used
  • Understand the value of full-time redundancy options for networked audio

Symetrix was one of the first manufacturers to adopt Dante as a multi-channel audio networking solution. Dante audio networking utilizes standard IP networks to transmit high-quality, uncompressed audio with near-zero latency. It is the most economical, versatile, and easy-to-use audio networking solution, and it is scalable from simple installations to large-capacity networks running thousands of audio channels. One of the benefits of every Symetrix Dante-enabled DSP is the embedded Dante network interface. The Dante interface is built into Dante-enabled DSPs instead of being an optional card. This lowers system cost. Symetrix provides an extra level of control over all Composer supported Dante devices. All Symetrix Dante DSPs feature gigabit Dante ports and they are capable of 64 transmit and 64 receive channels of Dante networked audio in addition to their analog I/O count.

The Prism line of Dante DSPs feature a single Dante port and should always be connected to a network switch. Radius NX and Edge all feature dual Dante ports. These DSPs are capable of operating in either switched or redundant mode. While in switched mode, these ports enable the DSPs to either be direct connected or daisy-chained with up to 10 other Dante devices without the use of an external network switch.

The Symetrix line of Analog Dante I/O Expanders increase the analog input and output capabilities of any Dante network when connected to a Symetrix Dante capable DSP. The xIn 4, xOut 4, and xIO 4×4 have a single Dante port and, are powered over Ethernet by an IEEE 802.3af Class 0 standard compliant switch, or by the included PoE injector. No other external power supply is needed or used. Because these three models have a single Dante port, they cannot be daisy-chained to each other. 

The xIn 12 and xOut 12 analog Dante expanders have dual Dante ports and can be configured in either switched or redundant modes. Because they have dual Dante ports, they can be directly connected to any Symetrix Dante DSP, or they can be daisy-chained with up to ten other Dante devices without additional network hardware.
