Symetrix Edge DSP

Total Input/Output Flexibility. When a preconfigured DSP just won’t do, Edge provides four versatile option card slots enabling unique I/O configurations – aligning the hardware with the exact system requirements. Optional cards support analog and AES-3 digital I/O as well as special purpose interfaces including USB, AEC, VoIP, and analog telephone.

Dante™ in Our DNA.  Edge DSPs are equipped with an optional factory installed 128 (64×64) redundant Dante channels. The Dante protocol enables ultra-reliable multi-channel audio networking over IP. Together, Symetrix and Dante provide the fastest possible way to implement, control, and maintain a system of networked DSPs and accessories – including third party Dante-enabled microphones, loudspeakers, power amps, and mixing consoles. And an option without Dante provides even more accessible DSP pricing for standalone systems.

On-board 10/100 and Gigabit Switches.  Unique to Symetrix Radius and Edge DSPs, built in switches lower system cost, reduce or eliminate the need for peripheral switches, and increase system reliability.

Unlimited Programming Flexibility.  Edge is programmed using Composer – Symetrix’ award winning open-architecture CAD application. Unique to Composer is the ability to natively configure Symetrix and select third party Dante hardware – thereby eliminating the confusion of multiple or redundant software applications. Learn more about Composer here.

Control Made Easy.  Multiple control options include low-cost Symetrix ARC wall panels and an easy to generate SymVue Windows virtual GUI. The human readable Composer Control Protocol supports programming of third-party touch screens and control devices.

An Embedded Web Server for Status and Even More Control.  Edge’s embedded web server displays I/O levels, diagnostics data, and hosts ARC-WEB – a browser-based interface for smart phones, tablets, and computers.

Early to the Party.  In 2007 Symetrix recognized the need for a standardized, high performance digital audio networking protocol – not only for our own products but for the pro audio industry at large. After considerable research, we aligned with Audinate to become one of the earliest licensees of the Dante protocol. The choice has proven prescient. Legacy protocols like Cobranet have faded into obscurity. Newer protocols, AVB for example, have failed to gain traction due to inherent technical drawbacks. With hundreds of third party licensees and a list of commercially available products that is growing exponentially, Audinate’s Dante protocol is now an established standard – far and above any competition.

Since the introduction of our first Dante enabled product in 2012, we’ve leveraged the benefits of the protocol for our own box-to-box audio networking, as well as for peer-to-peer connection with major third parties including Yamaha, Shure, and AudioTechnica. In countless case studies, designers have used off-the-shelf switches and cabling to link Symetrix DSPs to Dante-enabled mixing consoles, microphones, power amplifiers, loudspeakers, and laptop computers.

Dante is in our DNA … and that has placed us in a highly advantageous position. While our competitors choose to design for and support multiple network audio protocols, in some cases proprietary, Symetrix designs for and supports only one ubiquitous and clearly accepted industry standard: Audinate’s Dante.

Economical and Versatile.  Dante does away with heavy, expensive analog cabling, replacing it with low-cost, readily available CAT5e, CAT6, or fiber optic cables. Using Dante’s logical routes instead of physical point-to-point connections, a network can be expanded and reconfigured at any time.

Symetrix Dante systems scale from a simple pairing of a DSP and an analog I/O expander, to multi-DSP distributed networks. System designers use Symetrix Composer software to easily connect Symetrix DSPs and analog I/O expanders to third-party Dante equipped mixing consoles, microphones, power amplifiers, loudspeakers, and computers.

Outstanding Audio Performance.  Using the Dante protocol, Symetrix transmits and receives uncompressed full bandwidth audio with up to 32 bits of resolution at a 48kHz sample rate. Audio is transmitted and received digitally eliminating the analog challenges of interference from other electrical equipment, crosstalk between cables, or signal degradation over long cable runs.

Glitch-Free Redundancy.  Symetrix Radius, Radius NX, Edge, xIn 12, and xOut 12 Dante-enabled products support glitch–free redundancy, enabling a secondary physical network to duplicate the audio traffic on the primary network, automatically preventing audio loss or interruption in the event of a primary network connectivity problem.

Unicast or Multicast.  Dante channels can be configured as either unicast or multicast making the best use of available bandwidth. Unicast provides direct point-to-point connections; multicast streams audio to multiple destinations simultaneously.

Ease of Programming.  Composer is used to program Symetrix Dante equipped DSPs and analog I/O expanders. In addition to the programming of Symetrix devices, Composer also natively configures the setup and routing of select third-party Dante endpoints. Integrators can design a complete end-to-end DSP signal path using just one application.

The Symetrix Dante Advantage.  We provide our customers with a network audio solution that is flexible, dependable, scalable, and supportable. In short, just what you’d expect from an industry standard … and just what you’d expect from Symetrix.
