Formerly The Mosque and then The Landmark, Richmond’s Altria Theater has completed a US$50m renovation that includes a sound system based around a d&b audiotechnik loudspeakers and Symetrix Edge DSP control.
An architectural gem that dates from 1927, the Altira is the largest performing arts theatre between Atlanta and New York, with a seating capacity of 3,565 and an 18,000-sq-ft ballroom that holds 1,100 people and seats 600. Designed by Jaffe Holden in collaboration with the venue manager SMG and installed by Professional Audio Designs, the new sound system is employs four Symetrix Edge DSP units with additional outputs supplied by two Symetrix xOut Dante-enabled analogue expanders.
‘I’ve been using Symetrix products for more than eight years,’ says SMG Systems Engineer, Hayden Nebus. ‘I have 19 Symetrix DSPs right now. They sound phenomenal but the biggest factor for me is reliability.
‘You get a first order and a second order all-pass filter, and the second-order filter has a variable Q,’ he continues. ‘I can take a Smaart measurement, pull it into my FIR coefficient calculator, and import my FIR filter straight into the Symetrix DSP. Programming with Symetrix’ Composer software is more straightforward than any other open architecture DSP. And the value can’t be beat: Symetrix Radius and Edge DSPs are great values, and the Prism provides amazing DSP horsepower per dollar.
‘The [Symetrix Edge DSPs] handle the whole thing, including input matrixing, output matrixing, EQ, delay, FIR filters and all-pass filters, plus 12-mix stage monitor processing, distributed lobby and backstage 70V feeds, assistive listening, paging and chiming.’
The Edge processors control a d&b audiotechnik sound system with a 12 full-range V-series cabinets and two flown subwoofers per side, plus a centre hang of ten V-series cabinets and two subwoofers. The system includes front fills and up fills, and the balconies are handled by a mix of delay speakers, divided into three rings – one for the orchestra level, one for the first balcony area beneath the second balcony, and an over-balcony ring.
Nebus is enthusiastic about a processing feature he created for the installation: ‘My favourite part of that Symetrix rig, other than how gorgeous it sounds, is the “virtual babysitter” I built into the processing,’ he says. ‘On all main PA outputs, I have threshold detectors and counters. Every time the output reaches -0.5dBFS, the counter ticks. There’s a control screen with all the PA output meters, and each has a counter box above it that displays the corresponding threshold count. The counters get reset regularly, so I can tell you how many times you’ve clipped the rig, or come within 0.5dB of clipping, since soundcheck began, and when it last happened.’
With his many years of experience, Nebus has great confidence in Symetrix processors: ‘With Symetrix DSPs, I know we’re getting the right tools, I know they will perform reliably, and the value can’t be beat,’ he says. ‘Symetrix is the bleeding edge of audio processing.’
