AVoIP Case Study: DSP and management over IP at legendary hotel

A Radius and Dante network supports 128 channels for reliable multi-channel audio over IP
Publish date:

At the Sofitel Legend Metropole in downtown Hanoi, guests get a taste of colonial-era grandeur and luxury from an array of amenities. The hotel's two floor, 330 square meter angelina cocktail bar, whisky lounge and restaurant features a bespoke bar counter with an 8 meter backdrop, a designer whiskey lounge, and top quality comfort food from Europe, Australia, and the U.S. and serves as Hanoi’s benchmark entertainment venue with many moods.

A recent concept change and complete rebuild included a new sound system. Systems integrator DesignLive Technologies earned the contract with a tightly integrated, easy-to-use, customized solution based on a Symetrix Radius 12x8 EX audio DSP, Fulcrum Acoustic loudspeakers, Dynalite lighting control, an AMX NetLinx NX-series integrated controller, and iRidium for AMX touchscreen UI controls.

Observes DesignLive’s Thu Ta, “angelina is segregated into many creative nooks and crannies. A back-end Symetrix Radius processor allows hotel staff to manage and manipulate discrete zones via a custom layout UI on an iPad, combining and separating spaces based on immediate requirements. The Radius 12x8 EX DSP's zone management tools also manage an exclusive private dining room, where an automated AV system enables boardroom meetings, digital signage, and private events.”

Symetrix’ Radius DSP provides 128 (64x64) redundant Dante channels for reliable multi-channel audio networking over IP. The Radius12x8 EX model provides 12 switchable balanced mic or line-level inputs with 48 volt phantom power for condenser microphones, as well as 8 line-level outputs. Built-in 10/100 and gigabit switches reduce or eliminate the need for peripheral switches, lowering system cost and increasing reliability.


The Radius 12x8 EX manages a Dante network that feeds Fulcrum Acoustic Prophile P 8-inch coaxial loudspeakers and US212 dual 12-inch direct-radiating subwoofers. Wall plates provide analog inputs into the network—especially useful for DJs—and DesignLive provided spare CAT6 cable drops around the venue to provide Dante network access throughout the space, enabling the staff to customize the audio configuration for various events. “To tie all the systems together, we installed an AMX NetLinx NX-series integrated controller,” Thu reports. “A custom-programmed iRidium iPad control UI allows the venue's floor manager to manipulate light, sound, and visuals over Wi-Fi.”
