Nexo the Dynamic Cargo on Edinburgh’s Waterfront
Constructed by Festival Builders at a cost of £1.4m, Cargo offers spectacular views of the canal. But the two large open plan concrete-floored spaces, linked by a stairway and encased in glass, posed acoustic problems for installers Graeme Anderson and Mike McGuigan of Dynamic Productions Ltd — working with architect Lee Boyd and project designer John Mackenzie — who had to tame what was essentially a live room.
Dynamic are a preferred contractor to Festival Inns, who also own Three Sisters and Beluga in the city (part of a 26 club and bar portfolio). They have been using Nexo as their lead loudspeaker brand for the past three years.
At Cargo, they have flown quantities of PS10’s (12 upstairs, 10 below), with four PS8’s and four LS500 subs in both areas as part of a complete sound, lighting and multimedia package.
It’s the power-to-size ratio of the Nexo boxes that has proved the winning formula for Graeme Anderson over the years. “The PS8 is an incredible speaker for its footprint, and the PS10’s here sound brilliant,” says Graeme.
But it was the siting of the LS500 subs upstairs which provided his greatest challenge. “Since everything is glazed and there are no walls, we decided to fly them,” he reports. The subs are connected to the walls via Neutrik Speakons, and are easily demountable.
It was Tim Harrison, Fuzion’s technical guru, who provided the necessary technical assistance. “Tim helped with the design and layout, recommending we cut down the number of speakers and redirected all the sound inwards to avoid having to drive the system too loud.” As a result, with pairs of PS10’s mounted on each of the support pillars — and each Nexo enclosure with its own dedicated control — there is no sound cancellation and everyone is in close proximity to a sound source.
Principally designed into a two-zone system the PA derives its power from nine Camco Tecton ampliers — which like the PS enclosures are distributed in the UK by Fuzion plc. All equipment for this project was supplied by Northern Light.
Along with its bigger Vortex brother,Tecton is built along the same guidelines of huge power output, light weight and hi-fi sound quality, the main difference being that the Tecton is optimised for 4-ohm loads and dispenses with the remote monitoring facility.
While seven 24.4 (2400W W/4 ohms) amplifiers are assigned to the PS10’s, the installers have used 28.2’s (optimised for 2-ohm loads) on the LS-500’s.
Each floor can operate independently, or the sound sources — derived from MP3, CD and DJ playback, and satellite TV — can be switched.
With both the PS10’s and PS8’s fully optimised via their respective TD system controllers, and the whole system under DSP control, both Graeme Anderson and Festival Inns are delighted with the results.
