Here are some interesting videos related to PA and sound reinforcement systems. Wikipedia defines that a public address system (PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. The term, sound reinforcement system generally means a PA system specifically for live music or performance. A sound reinforcement system for a rock concert or other large event in a stadium may be very complex.

Finally a solution – RED ALERT has proven to be an effective way of preventing DJs running their levels into the red, and is a unique product, we do not know of any other device that is so simple and effective at solving this universal issue.
When the DJ mixer output goes into the red a big red lamp on the RED ALERT will flash reminding the DJ to take the level back slightly. Simple.

Live Sound Challenges and Troubleshooting
Live sound engineering comes with a unique set of challenges that require quick thinking and problem-solving skills to troubleshoot effectively. Here are some common live sound challenges and tips for troubleshooting them:
Kindly Subscribe to my YouTube: https://youtube.com/@mixedbydrcrack?si=kWIC7KSjQD2ULubg
1. Feedback:
– Cause: Microphones picking up sound from the speakers they’re being amplified through, creating a feedback loop.
– Troubleshooting: Move microphones away from speakers, use directional mics to minimize pickup of ambient sound, apply notch filters to remove specific frequencies causing feedback, and lower stage volume.
2. Poor Sound Quality:
– Cause: Room acoustics, improper microphone placement, or EQ issues.
– Troubleshooting: Adjust EQ settings to compensate for room acoustics, reposition microphones closer to the sound source, and use sound absorption panels to reduce reflections if possible.
3. Microphone Dropouts or Interference (Wireless Systems):
– Cause: Frequency clashes with other devices, low battery, or range issues.
– Troubleshooting: Check and replace batteries, ensure the wireless system is within range, scan for clear frequencies, and coordinate frequencies with other wireless users in the area.
4. Inconsistent Audio Levels:
– Cause: Performer movement, varying input levels, or equipment malfunction.
– Troubleshooting: Use compression to even out levels, instruct performers on proper mic technique, and check for faulty cables or equipment.
5. Equipment Failure:
– Cause: Faulty cables, connectors, or hardware failure.
– Troubleshooting: Keep spare cables and microphones on hand, regularly maintain equipment, and quickly swap out any faulty gear during the performance.
6. Hum or Buzz in the Sound System:
– Cause: Ground loops, electrical interference, or bad cables.
– Troubleshooting: Use DI boxes with ground lift switches, ensure power supplies are properly grounded, and replace any cables that are damaged or suspected to be the cause.
7. Difficulty Hearing Monitors:
– Cause: Stage volume too high, poor monitor placement, or inadequate mixing.
– Troubleshooting: Reposition monitors for better coverage, lower stage volume, and adjust monitor mixes to suit each performer’s needs.
8. Muddy or Boomy Sound:
– Cause: Room modes, excessive low frequencies, or poor speaker placement.
– Troubleshooting: Use high-pass filters to remove unnecessary low frequencies, reposition speakers to avoid bass buildup, and adjust EQ to clear up the mix.
9. High-Pitched Squealing (Ring):
– Cause: Specific frequencies are resonating, leading to feedback.
– Troubleshooting: Use a graphic EQ to identify and reduce the problem frequencies, often referred to as “ringing out” the system.
10. Vocal Clarity Issues:
– Cause: Poor mic technique, EQ settings not optimized for speech, or competing frequencies from instruments.
– Troubleshooting: Instruct performers on proper mic usage, carve out EQ space for vocals, and ensure vocal mics are high-quality and appropriately positioned.
When troubleshooting, it’s important to remain calm and systematically go through potential causes and solutions. Often, issues can be resolved by simple fixes such as adjusting levels or replacing a cable. For more complex problems, a deeper understanding of the sound system’s signal flow and the specific equipment in use is necessary to identify and rectify the issue.

Tomi Engdahl says:
It is hard to produce the full acoustic image with the usually limited stereo PA system. Stereo PA can produce in best case quite convincing acoustic image to listeners that sit in a small “sweet spot”. People in other locations do not get accurate sound image. Often in real-life situations even the people in sheet spot do not get a good acoustic image. But together with stage visuals the end result is often quite enjoyable.

Red Hot Chili Peppers: Gear Rundown with Toby Francis

In the world of live sound, Toby Francis needs no introduction. He’s one of the all-time greats, and has mentored and influenced an entire generation of aspiring live sound engineers.
Since Toby generally carries a mountain of RND equipment on the road with him, we’ve had the pleasure of interviewing him on several occasions – but this time around, we decided it would be more fun to have another engineer do it so they could geek out together.
Dani Muñoz was mixing Thundercat on this particular tour last year, and he was kind enough to spend some time with Toby going through his rig and discussing some of the techniques that Toby uses to create the best-sounding shows on the planet. (Spoiler: it involves a lot of Silk Red.)

Meyer Sound Shakes Up Stadium Concert Paradigms on Metallica’s Epic “M72 World Tour”
European Leg Concerts Debut Massive PANTHER Line Array System
https://meyersound.com/news/metallica-m72-world-tour/
Metallica, a creative powerhouse lauded as one of rock’s preeminent bands, continues to break new ground with the dynamic, in-the-round production for the global, two-year “M72 World Tour” that recently kicked off in Europe. Throughout the tour, the band’s sound is immersing the entire audience — at full bandwidth across a broad stereo landscape — through a Meyer Sound system comprising a record 288 PANTHER large-format linear line array loudspeakers.
Crafting the Metallica sound from FOH is Greg Price, a veteran known for his long stints not only with hard rock legends Black Sabbath and Ozzy Osbourne but also for pop acts including “The Glee Show on Tour,” Hannah Montana/Miley Cyrus, and Chicago.
As for the massive PANTHER arrays, Price describes them as “a PA system that acts like a reference monitor, like an Amie or a Bluehorn in the studio. I’m hearing things in my mixing that I always knew were there but lacked definition. Now they are right in my face, and I can work with them.”
The gargantuan “M72 World Tour” system is deployed in three concentric rings. The outer ring arrays are suspended from eight towers, with two PANTHER arrays on each tower: 16 cabinets per array on the four long-side towers and 13 cabinets on the four short-side towers. Each tower also carries dual hangs of six-each 1100-LFC low-frequency control elements and one set of six VLFC very low-frequency control elements.
The inner system, suspended from a web over the stage, has eight hangs of seven-each PANTHER line array loudspeakers, providing stereo coverage out to 42 meters from center. The “doughnut hole” in the stage center is covered by eight inward-firing UPQ‑D2 narrow coverage loudspeakers, while the outer side of the ring employs 20 ULTRA‑X40 compact loudspeakers as front fill. Ground sub-bass is powered by eight sets of 2x 1100-LFC elements around the stage.
The entire system is connected, controlled, and monitored over three MILAN AVB networks. One network connects Milan directly to all 288 PANTHER loudspeakers via 10 Galileo GALAXY 408 and two Galileo GALAXY 816 Network Platforms using a fiber network incorporating 26 Luminex Gigacore switches. The other two networks are primary and secondary networks for signal distribution and monitoring of the remaining analog Meyer Sound loudspeakers as well as providing redundant analog inputs to the PANTHER loudspeakers. The three networks comprise 52 Luminex switches and 35 GALAXY Network Platforms. Meyer Sound’s new Nebra software platform manages all network configuration, connection, and real-time system monitoring.
As yet another innovation, the “M72 World Tour” employs Meyer Sound’s Spacemap Go spatial sound design and mixing tool to a limited extent, but with stunning effect. As an intro to “One,” the rumble and roar of a four-engine vintage bomber circles the stadium with convincing reality.

Meyer Sound goes round for Metallica world tour
https://www.lsionline.com/news/meyer-sound-goes-round-for-metallica-world-tour
“I’m always concerned about making all these new ideas work at scale,” admits Braun, “but we have great partners to rely on, not the least of which is Meyer Sound. So, I never let things like practicality and logistics inhibit the creative process.”
Braun took his idea for the tour sound directly to company founders John and Helen Meyer, who captured his vision and assigned director of system optimisation Bob McCarthy to design audio for the tour.
“I told Bob that my goal was to have full stereo sound at every point with no overlap, from the centre pit to the nosebleed seats,” Braun continues. “We wanted everybody to hear the band as if with nearfield monitors, and I think we’ve come closer to that than ever before in a concert setting.”
Braun also credits the new Panther line array loudspeakers as a key component in realising the ambitious concept. “The clarity of the system is breath-taking, and that combined with Bob McCarthy’s brilliant design is giving us a show that sounds spectacular.”
The gargantuan M72 World Tour system is deployed in three concentric rings. The outer ring arrays are suspended from eight towers, with two Panther arrays on each tower: 16 cabinets per array on the four long-side towers and 13 cabinets on the four short-side towers. Each tower also carries dual hangs of six-each 1100-LFC low-frequency control elements and one set of six VLFC very low-frequency control elements.
