The source of sound are located behind and above the performers so they hear what the audience hears. 12 inch speakers. He did some research and said, ‘Let’s use Altec speakers and hi-fi amps and four-tube amps, one for each instrument, and put them on a piece of wood.’ Three months later we were playing through Bear’s sound system.”. *Pics - Jim Anderson. This precise match made our noise canceling performance outstanding It was made for this. Wider separations The Wall solved a huge number of the bands sound problems, however, understandably, the system created a number of technical issues of its own. The Grateful Dead sound system is really 11 independent systems or channels as shown in the table below. On the remote control panel is a switch for each Rock and roll was in its adolescence, constantly growing and evolving. They also don’t have dedicated amps and speakers for each instrument – this has been somewhat countered with modern improvements in these technologies. Always striving to improve, Owsley kept a ‘sonic journal’ of each performance, so he could improve on his setup and mix for each concert and highlight issues to the band. Improvements will be made to the drum system pickup with “The one thing I insisted on that they did listen to me about was, I insisted on sound checks, and I encouraged them to listen to tapes of their performances,” Owsley stated in some biographical notes, “not just so they could hear how they sounded, but also to correct me on what I was doing, because I tried to make the tapes as much like the way it sounded in the hall as possible. The design of multi-way with the system. His frustrations can be heard in an interview with Grateful Dead biographer Dennis McNally: “I found on my release from jail that the crew, most of whom had been hired in my absence, did not want anything changed. It goes without saying, singers who could hear themselves didn’t have to strain their voice just to hear themselves, drummers didn’t have to beat their skins off, bassists could minimize their mud and lead guitarists, well they stayed about the same. That’s the only way you’ll ever get close to true art.”. Before long they were creating their own products, and in a few short years, Alembic incorporated three shareholders: Ron Wickersham, the electronics expert, Rick Turner, a luthier, and Bob Matthews, a recording engineer, all who would later help out on the Wall of Sound. microphones. There have been more powerful speaker systems built sure, but in terms of sheer, unbridled engineering, in a time where there was nothing like it on the planet, it remains unparalleled.

It used six separate sound systems which were able to isolate eleven … Rumoured to have especially sweet sonic qualities, the venue was a converted ice rink and by this point was showing wear from decades past. A noise problem (hiss) was first attached with keyed amplifiers installed It is rumoured that Owsley took inspiration from Buffalo Springfield’s monitoring setup, during a concert where they shared the bill with the Dead. Changes have been made continuously in all directions which an echo-like delay of different sound colorations and textures. form the source can be aimed by adjusting controls. Often, splitter connections must be made to the microphones for It was the brainchild of audio engineer Owsley “Bear” Stanley.

A year later, the bulk of the wall was complete, however, it required continual development throughout the short history of its use. Live sound, however, had not kept up with the growth spurt and, simply put, the primitive public address systems of the time were just not as good as the music. reverberation.

At first, Bill and I were laughing, but then we said, ‘Wow, he’s really serious.”. A terrific short piece on YouTube regarding the Wall of Sound - Recent Interviews and Clips from The Grateful Dead Movie. Nonetheless, the Wall the way live sound engineers thought about their designs. new bass has a frequency response with a crisper tone, and two quad pickups and 4) mix unequalized unfiltered direct sound with the filtered sound. Pechner remembered that he overheard a tense band meeting, discussing the total cost of designing and testing the system – $275,000, which he thought that was a pretty conservative estimate (this did not consider the regular costs of paying the large crew, as well as transport and maintenance costs). It turned out that cooking acid became illegal, but that didn’t stop Bear Owsley. which gives him complete control of frequency responses by enabling boost The Dead’s intermittent drummer Mickey Hart told Rolling Stone about walking in at this very moment. divides the frequency range into three parts.

The sensitivity of the microphones is controlled But Bear Owsley disagreed. work with computer assisted and synthesized music will continue. He moved onto some serious ballet training, and after he felt that part of his life was over he enrolled at the University of California. Since teh instrument has the capability used preamplifiers designed to use the measuring microphone elements with report. Bassist Phill Lesh recalled the beginning of this journey to Rolling Stone.

The Wall Of Sound outside in the sunshine. Garcia He was addressing these electronics as if they were a person. The mad-genius knew that sometimes you have to push the envelope and sometimes you just do it because you can. The Wall of Sound was built exclusively for the Grateful Dead and it was used on their tours from 1974 to 1976. On top of this, it took four semi-trailers to haul 75-tonnes of amps, speakers, subwoofers and tweeters. It’s no surprise then that the Wall of Sound almost sent the Dead bankrupt, almost as soon as it rose the roof, it was time to pull it back down again. and treble pickups covering all the strings, and a quad pickup which has found only one which would give us better matching than the dynamic microphones. Deadheads and engineers who were lucky enough to hear the Wall in all its glory claim that in terms of clarity of sound it still hasn’t been beaten. extensions beside Kieth and BIll. a single power amplifier of the type used in the rest of the system. The piano system is smaller than the vocal system but configured very This control permits the performer to control The original Wall of Sound, as envisioned in 1972 by audio engineer Owsley “Bear” Stanley and created with Dan Healy, Mark Raizene, Ron Wickersham, Rick Turner and John Curl, was a true physical wall of speakers, comprised of six separate PAs placed on scaffolding behind the Grateful Dead, acting as a simultaneous monitor and house system. Low-fidelity amps and speakers at the time limited and guided popular music forms which were simple, loud, and often distorted. University of Nevada - Reno, NV. the difference was taken by an ultra low distortion amplifier. bass without intermodulation. Live sound engineers have taken note of Owsley’s experiment, and as technology improved, found ways to offer greater consistency, but perhaps not with the same specific clarity and detail. the transparency of sound maintained. This can cause a substantial increase in the apparent The Grateful Dead gave the sneak peek of the Wall of Sound on February 9, 1973 at Stanford University’s Maples Pavilion but it was on March 23, 1974 when they debuted the completed system during their tour stop at the Cow Palace in Daly City, California.

Coliseum, Vancouver, British Columbia on May 17th, 1974. electronics makes it possible to design a phased array where the energy Conventional Each singer has a perfectly matched pair of For recording and broadcasting, each microphone is provided with separate wall. And so in late 1972, he worked with the Dead’s sound crew Dan Healy and Mark Raizene, and Ron Wickersham, Rick Turner, and John Curl of Alembic to deliver high-quality sound to concert attendees. Tears streamed down his face and he whispered to the mass of wood, metal, and wiring, with the tenderness of any parent witnessing their child’s first recital. hello dear friends, is there any weirdo from the wall of sound out there who can explain and tell me everything he knows? All the direct (vocal) microphones were resistively summed and all the difference amplifiers which has two transformer isolated outputs. The band would only hear themselves after the sound had bounced around the walls of the given room and the bodies of the audience. All the control of what’s going to the audience should be fully in the hands of the performing artists themselves. Clockwork work phaser system, an Orban/Parasound studio reverberation unit. In 1967 he was caught with 350,000 doses of LSD and 1,500 doses of STP and spent three years in the grey-bar hotel. Another roadie named Steve Parish reminisced that system took 21 crew members all day to set up: “You had to get up at 6am, it took all day to put it up, but we had it down to a science.”. In 1969, a meeting took place between Bob Weir, Phil Lesh and Jerry Garcia and a small group of their close collaborators. I am a firm believer that the very best way to enjoy an audience recording is to listen to one recorded outside. 533. better.

The signals from each of the vocal microphones are brought together by whole surface of the cluster acts as one working surface. Members of the Grateful Dead and the Wall of Sound, shot during sound check at P.N.E. The design and build process took months, with many ‘proto-walls’ being constructed to test the complex system. The variety of sounds which can be achieved on the bass is the result of Stan Owsley was a good friend of theirs – a sound guy, acid chemist, and ex-professional ballet dancer. as a technical and group enterprise, a sort of logical accumulation of speakers Be the first to know about the Grateful Dead’s exclusive limited-edition releases, breaking news on the band, community events, and so much more. Alembic became highly prolific in sound recording, modifying and repairing guitars, basses, and P.A. Another benefit of this system was that audience members heard the instruments, and voices, where they saw it, through the same channels as the band members. a differential summing amp, where phase purity can be regulated and hence Owsley’s grand design was also the first of its kind to eliminate the need for a sound guy, at least at the front of house. 10KHz! The Grateful Dead and their ragtag group of roadies and Deadheads were known for a DIY, self-sufficient attitude, and began to take matters into their own hands. This is the original image of the Wall of Sound licensed by Grateful Dead Productions. much vertical dispersion, and horizontal dispersion is ideally between 140 It was here that Owsley proposed putting the P.A behind the band. The center cluster of the vocal system, consisting of high and midrange The bass was transmitted through a quadraphonic encoder, which took a signal from each string and projected it through its own set of speakers. He was the first to angle a speaker towards the player, using directional microphones to cancel out feedback. often sound worse than simple observation of reverberation times might indicate ambiance (noise canceling) microphones were resistively summed and then Was his ludicrous wall built just for the sake of it then? which is switchable in many microphones to roll off the bass response.) All this weighs about Regardless, it was a monumental amount for 1974, a figure that today would be well into the millions. instead of one, the new one being a frequency-detector pickup. Vocals, rhythm guitar, piano each had their own. 3938 Tracks. tweeters. The result, more often, was ugly: colliding frequencies, distortion and feedback issues were the norm. This particular event was immortalised in one of the bands greatest hits, the 1970 song Truckin’:“Busted, down on Bourbon Street / Set up, like a bowling pin, Knocked down, it gets to wearing thin / They just won’t let you be.”. There is a The pickup is by means of condenser elements suspended separate volume control for each of the five Countryman custom pickups (one These buildings hide. Because of the antinoise characteristics of the microphones, the sensitivity This is a first-order After a hallucinatory incident, where Owsley ‘saw’ the Grateful Dead’s sound, he became obsessed with aural perfection and started on an endless path, working with the band, to achieve it. Due to the nature of guitar sounds, only about 5% some problems for first-time users who must not wander around as they may microphone in the same manner as a "voice" response inductor If anyone had some qualms with the job, it was Richard Pechner, a roadie, carpenter and photographer for the band, who assisted in the mammoth construction job. in the open air quite an acceptable sound at a quarter of a mile and a fine buttons on the bass allow Phil to select any one of sixteen quad spatial See more ideas about wall of sound, greatful dead, grateful dead. is a confusing sound which causes the musicians and sound system operators the tweeters. a cluster of 5 and 12 inch speakers built in the same fashion as the vocals for voice and drums will be added to further carry out the separate source Conventional systems are set up low to the ground When the input impedance is much higher than Well in Owsley’s own words: “The Wall of Sound is the name some people gave to a super powerful, extremely accurate P.A system that I designed and supervised the building of in 1973 for the Grateful Dead. We had used various commercial microphones and found omnidirectional and $74.99 $ 74. Monitor technology gradually improved as the decade rolled on , making it easier for performers to hear themselves and the rest of their band clearly, resulting in better tuning, timing and a tighter performance altogether. lounder than the note. My guess is the Dead's '74 sound system started being called the "Wall of Sound" in the late '70s - or even early '80s, as the label spread among fans. (The comparison with Phil Spector's "wall of sound" was presumably coincidental.) Unlike the Wall, subsequent live sound designs, have obviously required an engineer to operate the system. As the ’60s rolled on, sound engineers began to experiment with different P.A. Bruel and Kjaer microphones hooked up out if phase, only one of which he Owsley had studied engineering at the University of Virginia, before dropping out for a stint in the air force. difference of the sound pressures at two distinct points. would open the hiss for an entire band and this hiss was sometimes subjectively There were numerous renditions and developments of the Wall, but the largest version used 586 JBL speakers and 54 Electrovoice tweeters and was powered by 48 McIntosh MC-2300 amplifiers, which resulted in a continuous 28,800 watts. The main He met the Grateful Dead through Ken Kesey, during one of his infamous ‘acid test’ parties in 1965. conventional gain controls were used and thus the signal path was kept as The hunt is on for its first Dead appearance. Together they created the legendary Wall of sound. inch transducers. roll-off the low frequency in voice since the low frequencies of the vocalist A feat of engineering only he could dream of, let alone accomplish. As Owsley so eloquently put it in some biographical notes: “As far as I’m concerned, the sound man should be as superfluous as tits of a boar hog… All he should do is make sure things run and don’t break down; plug the wires in and unplug them. and Kreutzman both have piano monitors or fills in their areas of the stage, The wall was not built overnight. They wanted to maintain the same old same old which under their limited abilities, they had memorized to the point where they could sleepwalk through shows.”. “The Wall of Sound is the name some people gave to a super powerful, extremely accurate P.A system that I designed and supervised the building of in 1973 for the Grateful Dead. gradient microphone and it possesses excellent antinoise characteristics. “I started talking to Bear about our sound problems. 18 high. would particularly like to recognize, The whole system operates on 26,400 Watts of continuous (RMS) power, producing They would often hear a version of the sound that was delayed, and with reverberations produced by the club, hall or stadium.

In the ’60s it wasn’t uncommon for bands to solely use the power of their amplifiers to project to the crowd. Even if a band had the luxury of amp mics, monitors were unheard of. There was a reason why The Beatles stopped touring in 1966. Monitoring allowed the band to hear themselves fairly well, but Owsley was not satisfied with the standard speakers and amplifiers that were available to him, so he and his apprentice clandestine-chemist Tim Scully began modifying and manufacturing their own audio gear. a different direction, the echoes are more diffuse and therefore less objectionable. The system represents the efforts of many people. effect due to path differences between sources carrying coherent information. Sunday, May 12, 1974.
