When Capital Sound, part of the Solotech UK Group, conceived the original design for Stereophonics’ homecoming concert at the Principality Stadium, for what would have been their ‘We’ll Keep A Welcome’ Christmas show, the idea of 23 Martin Audio PA hangs (covering both an A stage and 40-metre thrust to a B stage) was entirely achievable.

“The kit was already prepped and ready to go out, when the show was suddenly cancelled,” Solotech Senior Technical Advisor, Robin Conway said.

But when the gig was rescheduled for June, there was none of the luxury of pre-production time that had accompanied the original show.

Not only did the B stage now need to function as a totally independent stage, with its own PA, but Friday’s planned production/build-up day suddenly disappeared when the following night’s concert—which also featured Tom Jones—sold out.

This resulted in a second date being added … on the Friday.

The support line-up also changed at the last minute ,with Newport-based Feeder stepping in.

Meanwhile, back at London HQ, the crew worked around the clock to deprep inventory returning to base from other festivals, before reprepping and trucking it down to Wales. The crowd of 74,000-plus who filled the stadium under its closed roof were oblivious to this.

There was no compromise to the sound despite the production company needing to make a late provision for the incoming film crew, necessitating them to provide a separate broadcast feed in addition to the sound in the bowl.

Thus there was plenty to occupy the minds of the band’s long-serving sound engineer Dave Roden, Crew Chief, Tim Patterson, and system tech Mark Cleator, working alongside production manager Dave Nelson.

Not least of these was how to create 360° of coverage via the B stage system, with two hangs facing back towards the main stage, which obviously meant the audience had to turn around to see when the band performed there.

The main PA hangs from A stage comprised 18 MLA and one MLD (Downfill) enclosure per side. Behind them were two hangs of seven MLX subs in end-fire configuration, with side hangs consisting of 16 MLA per side.

Front fills comprised eight XD12 and 16 WPS (set in pairs on a shelf across the front of the stage).

For the B stage Cap turned to their new Wavefront Precision (WPL).

These hangs comprised 12 x SXHF218 in a single column, with 36 flown WPL—18 on either side of the subs—while outflanking these were two further hangs of 14 WPL and two hangs of WPC facing the main stage to complete the 360° coverage.

The Wavefront Precisions were driven in 2-box resolution from 24 iKON iK42 multi-channel amplifiers in a flown amplifier cart directly over the B-Stage.

The ring delay system, meanwhile, comprised eight hangs of eight MLA Compact.

Robin Conway explained the processing rationale. “Without the luxury of time we used a Dante-enabled Soundweb BLU-806 to create a custom-delayed matrix.

“Any part of the PA system applicable to A or B stages had different delay taps (for instance the ring system had two different times programmed as the action shifted from A to B stages).”

These delay taps allowed the FOH team to choose the entire system focus dependent on which, or how many, band members were performing on which stage at any given time.

“Overall, we got the result we wanted in the face of enormous challenges, and in fact this probably broke some kind of internal record. I doubt, in our history, we’ve fielded 23 separate hangs of PA for a one-off gig before.”
