One of the biggest, muddiest, and most magnificent music festivals in the world, Glastonbury 2025 has kicked off at the legendary Worthy Farm in Pilton, Somerset. With over 200,000 fans flooding through the gates, the farmโs been transformed into a wonderland of stages, lights, chaos, and โ most importantly โ bloody beautiful sound. ๐๐ค๐
While most punters are focused on whoโs headlining the Pyramid or whether their tent will survive the night (spoiler: it wonโt), weโre heading backstage to salute the real heroes โ the audio engineers and tech teams who make it all possible.
๐ช THE PYRAMID STAGE โ AUDIO NERD HEAVEN ๐
The Pyramid Stage isnโt just a triangle with big lights on it โ itโs a world-class sonic cathedral, and this year itโs running on pure DiGiCo muscle. Supplied and coordinated by RG Jones Sound Engineering Ltd., the audio rig is nothing short of audio black magic.
Letโs break it down:
๐งโโ๏ธ HOUSE MONITORS โ QUANTUM326 x2 ๐ง
๐ Position: Side-of-stage
๐ง Role: Handles artist foldback and in-ear mixes
โก Why it slaps: The Quantum326 is like the Swiss Army knife of monitor consoles โ 64-bit Super FPGA, Mustard processing, and Nodal Processing for ultimate flexibility. Perfect for juggling diva vocals, thunderous drum subs, and last-minute line checks from a panicked tech sprinting in wellies.
๐ก Key Features Used:
- Mustard compressors & tube preamp models
- Nodal Processing for individual aux-send shaping
- Dual solo busses for monitor A/B toggling
- Full Optocore integration with stage racks
๐ค Bands love it, engineers worship it, and it keeps even the most chaotic Glasto changeovers running smooth(ish).
๐๏ธ FRONT OF HOUSE โ SD12 x2 ๐ฅ
๐ Position: FOH tower, halfway to Narnia
๐ง Role: Controls the main mix the audience hears
โก Why it rocks: Compact, punchy, and properly powerful. The SD12 may look modest next to its bigger siblings, but itโs a festival workhorse with 96 channels, 16 FX engines, and two full touchscreens.
๐ก FOH Tech Loadout:
- Waves SoundGrid integration (for external FX plugins)
- Snapshot automation for rapid band switchovers
- Multi-band compressors for crowd-friendly dynamic control
- Full channel mirroring with Quantum852 via Optocore ring
These bad boys keep the FOH engineers cool as cucumbers even when the lead singer throws a mic into the crowd (again).
๐งฉ MAIN LINK CONSOLE โ QUANTUM852 ๐โ๏ธ
๐ Position: Backbone of the Pyramidโs entire audio network
๐ง Role: Acts as the central control node, handling I/O routing, clocking, redundancy, and overall signal distribution
โก Why itโs a beast: The Quantum852 is DiGiCoโs flagship, and this year itโs running the audio brain of the biggest stage in the UK. Boasting a 5th-generation FPGA and True Solo architecture, itโs like having the Millennium Falcon under your fingertips.
๐ก Big Tech Highlights:
- 2,000+ processing paths
- Integrated Waves and Dante support
- Redundant power and engine paths
- 12 onboard Mustard EQ/Compressors
- External clock sync and timecode generation for video sync
This is what makes everything go boom in the right order.
๐ง RACKS, LOOPS & LOOM RUNS โ BACKSTAGE WIZARDRY ๐๏ธ
You didnโt think that was it, did you? Thereโs a full network of DiGiCo SD-Racks and Mini Racks handling stage inputs and outputs, connected via Optocore fibre loop systems. These allow for redundant, high-bandwidth digital audio transport across the stage, FOH, monitors, and link console โ with near-zero latency.
๐ก Kit List Includes:
- 4x SD-Rack (32-bit mic preamps, high-res conversion)
- 2x SD-MiNi Rack (side fill and stage FX)
- Dual Optocore loops for failover safety
- Dante bridge to broadcast trucks (BBC and iPlayer feeds)
- Word clock distribution to light & video rigs
Every cable, patch point, and fibre run is colour-coded and labelled like a sci-fi lab. Absolute tidy setup.
๐๏ธ STAGE MIC SETUPS & IEM RIGS ๐ง
Depending on the artist, youโll find a mashup of industry-standard and bespoke mic kits, including:
- Shure Axient Digital Wireless Systems (vocal & instrument)
- Sennheiser e935s, e904s, and MD421s (for drums & guitar cabs)
- Neumann KM184s (cymbals, ambient mics)
- Radial JDI boxes (for bass and synths)
- Shure PSM1000 & Sennheiser G4 IEMs โ running multiple zones with failover backups
The techs even have RF spectrum analysers on standby for when 200,000 phones start fighting for airwaves mid-set. ๐ ๐ก
๐งฐ CREW & COLLAB โ WHOโS PULLING THE STRINGS?
Big shoutout to the tech legends making it all tick:
- RG Jones Sound Engineering โ primary supplier and integration leads
- DiGiCo โ on-site support, system tuning, and panic-button whisperers
- Capital Sound / Solotech / Britannia Row โ all working across Glastoโs various stages
- BBC Audio Engineering โ coordinating multitrack feeds for TV & iPlayer
- Monitor techs, FOH wizards, RF managers โ the unsung MVPs
Honestly, without them, all youโd hear is a sad cow mooing in the distance.
๐ FINAL THOUGHTS โ SOUND THAT MAKES YOUR RIBCAGE WOBBLE ๐ถ
Glastonbury 2025 isnโt just a festival โ itโs an audio Olympics, and the Pyramid Stage is its gold-medal arena. With Quantum852s linking the web, Quantum326s commanding the chaos, and SD12s delivering the thunder, this yearโs rig is one of the most advanced setups ever seen on Worthy Farm.
So the next time you’re losing your mind to a riff, a drop, or a surprise secret set โ remember the digital sorcery behind the scenes. DiGiCo and RG Jones? Proper job, mun. ๐
๐ ๏ธ Stay tuned for more behind-the-scenes Glasto updates โ weโll be covering Lighting, Backline, Stage Design, Weatherproofing Hacks, and maybe even Toilet Tech (yes, really).
