… a complete audio AEC solution in a single box …
A complete audio AEC solution in a single box. 8 AEC inputs, 4 aux inputs, 8 outputs, an expansion slot for any SymNet audio I/O option card, Dante network port.
Superior AEC for superior intelligibility. A complete audio AEC solution in a single box. Dedicated wide band processing. Zero latency direct outputs. Discrete references. Input from mic/line or internally routed signal. Unique features that combine to deliver perfect sound to far end participants. 8 AEC inputs, 4 aux inputs, 8 outputs.
Scalable Dante™ network audio – 64×64. From small and simple, to mega large and complex projects, Dante™ digital audio over Ethernet is an industry standard means for interconnecting multiple Edge, Radius and Prism DSP’s, Symetrix I/O expanders, and a growing range of select Dante enabled 3rd party peripherals including microphones and power amps.
On-board 10/100 and gigabit switches. Unique to Symetrix Edge and Radius DSP’s, built in switches lower system cost, reduce complexity, help to eliminate third-party peripherals while increasing system reliability.
AEC + any other required processing. In addition to dedicated AEC processing Radius AEC reserves an entire Sharc DSP chip for all the other processing requirements in and around the conference room: voice lift, room combine, mic and speaker EQ profiles, feedback fighter, automixing, and more. Everything in a single box.
More usable I/O in one unit. The addition of the versatile option card slot reduces total system costs by maximizing the number of inputs or outputs in a single 1U DSP. For example, adding a 4 Channel Analog Input card creates a 16×8 analog configuration; with a 4 Channel Analog Output card the result is 12×12. The expansion slot supports an array of audio I/O cards including 4-channel analog, 4-channel digital, 4-channel AEC and multi-line VoIP and analog telephone.
Control made easy. Multiple control options include zero cost ARC-WEB browser interface, low-cost Symetrix ARC wall panels, easy to generate SymVue Windows GUI. A stable, human readable protocol is used to program third-party touch screens.
Multiple user control options. Zero cost ARC-WEB browser based interfaces, low cost Symetrix ARC wall panels, easy to implement SymVue GUI executable for Windows machines, and programmable third-party touch screens.
Powerful, efficient DSP configured using award winning CAD design software*. Composer software processes audio and control signals in nearly unlimited ways serving countless applications. Unique to Composer is the ability to natively configure Symetrix along with select third party Dante hardware – thereby eliminating the confusion of multiple or redundant software applications.
