Wall Of Sound (Grateful Dead)
The Wall of Sound was an enormous sound reinforcement system designed in 1973 specifically for the Grateful Dead's live performances. The largest concert sound system built at that time, The Wall of Sound fulfilled lead designer Owsley "Bear" Stanley's desire for a distortion-free sound system that could also serve as its own monitoring system. History Stanley and Dan Healy and Mark Raizene of the Grateful Dead's sound crew, in collaboration with Ron Wickersham, Rick Turner, and John Curl of Alembic designed the sound reinforcement system in an effort to deliver high-quality sound to attendees of Grateful Dead concerts, which were drawing crowds of 100,000 or more at the time. The Wall of Sound combined six independent sound systems using eleven separate channels. Vocals, lead guitar, rhythm guitar, and piano each had their own channel and set of speakers. Phil Lesh's bass was piped through a quadraphonic encoder that sent signals from each of the four strings to a separate c ...

Sound Reinforcement System
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. In many situations, a sound reinforcement system is also used to enhance or alter the sound of the sources on the stage, typically by using electronic effects, such as reverb, as opposed to simply amplifying the sources unaltered. A sound reinforcement system for a rock concert in a stadium may be very complex, including hundreds of microphones, complex live sound mixing and signal processing systems, tens of thousands of watts of amplifier power, and multiple loudspeaker arrays, all overseen by a team of audio engineers and technicians. On the other hand, a sound reinforcement system can be as simple as a small public address (PA) system, consisting of, for example, a single microphone connected to ...

McIntosh MC-2300
The McIntosh MC-2300 is a solid-state power amplifier which was built by the American high-end audio company McIntosh, and sold between the years 1971 and 1980. In terms of McIntosh "family lineage" or production order, the MC-2300 was immediately preceded by the MC-2105 (with blue meters) and the MC-2100 (without), which were both 100 watt-per-channel stereo amps (200 watts monophonic) sold between 1969 and 1977. Before these came the MC-2505 (blue meters) made between 1967 and 1977, and the meterless but popular MC-250 sold from 1967 to 1979, both of which were 50 WPC stereo amplifiers (100 watts mono.) The MC-2300 was succeeded by the even more powerful MC-2500 (500 WPC stereo/1000 watts mono), sold from 1980 to 1990; and then the MC-2600 (600 WPC stereo/1200 watts mono), which was available between the years 1990–1995. Design Physically, the MC-2300 is a very large and sturdy amplifier, measuring 10.5 in (26.7 cm) high x 19 in (48.3 cm) wide x 17 in (43.2 cm) de ...

Condenser Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Feedback
Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation which may occur when an acoustic path exists between an audio input (for example, a microphone or guitar pickup) and an audio output (for example, a loudspeaker). In this example, a signal received by the microphone is amplified and passed out of the loudspeaker. The sound from the loudspeaker can then be received by the microphone again, amplified further, and then passed out through the loudspeaker again. The frequency of the resulting howl is determined by resonance frequencies in the microphone, amplifier, and loudspeaker, the acoustics of the room, the directional pick-up and emission patterns of the microphone and loudspeaker, and the distance between them. The principles of audio feedback were first discovered by Danish scientist Søren Absalon Larsen, hence it is also known as the Larsen effect. Feedback is almost always considered undesirable when it occurs with a singe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daly City, California
Daly City () is the second most populous city in San Mateo County, California, United States, with population of 104,901 according to the 2020 census. Located in the San Francisco Bay Area, and immediately south of San Francisco (sharing its northern border with almost all of San Francisco's southern border), it is named for businessman and landowner John Donald Daly. History Archaeological evidence suggests the San Francisco Bay Area has been inhabited as early as 2700 BC. People of the Ohlone language group probably occupied Northern California from at least the year A.D. 500. Though their territory had been claimed by Spain since the early 16th century, they would have relatively little contact with Europeans until 1769, when, as part of an effort to colonize Alta California, an exploration party led by Don Gaspar de Portolá learned of the existence of San Francisco Bay. Seven years later, in 1776, an expedition led by Juan Bautista de Anza selected the site for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cow Palace
The Cow Palace (originally the California State Livestock Pavilion) is an indoor arena located in Daly City, California, situated on the city's northern border with neighboring San Francisco. Because the border passes through the property, a portion of the upper parking lot is in San Francisco. History Completed in 1941, it hosted the San Francisco Warriors of the NBA from 1962 to 1964 and again from 1966 to 1971. The Warriors temporarily returned to the Cow Palace to host the 1975 NBA Finals as the Oakland–Alameda County Coliseum Arena was booked for an Ice Follies performance. It was the site of both the 1956 Republican National Convention and the 1964 Republican National Convention. During the 1960s and 1970s, the SF Examiner Games, a world-class indoor track and field meet, was held annually at the Cow Palace. The Cow Palace was also an important venue for professional boxing until the early 1980s, having staged regular shows, including ten world title fights and appearan ...

Tweeter
A tweeter or treble speaker is a special type of loudspeaker (usually dome, inverse dome or horn-type) that is designed to produce high audio frequencies, typically deliver high frequencies up to 100 kHz. The name is derived from the high pitched sounds made by some birds (tweets), especially in contrast to the low woofs made by many dogs, after which low-frequency drivers are named (woofers). Operation Nearly all tweeters are electrodynamic drivers using a voice coil suspended within a fixed magnetic field. These designs operate by applying current from the output of an amplifier circuit to a coil of wire called a voice coil. The voice coil produces a varying magnetic field, which works against the fixed magnetic field of a permanent magnet around which the cylindrical voice coil is suspended, forcing the voice coil and the diaphragm attached to it to move. This mechanical movement resembles the waveform of the electronic signal supplied from the amplifier's output ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maples Pavilion
Maples Pavilion is a 7,392-seat multi-purpose arena on the campus of Stanford University in Stanford, California. Opened in 1969, Maples underwent a $30 million renovation in March 2004 and reopened ahead of schedule, in time for conference play that December. It was named after its principal donor, Roscoe Maples. History Roscoe Maples was an Oregon lumber magnate. Upon his death in 1963, Maples bequeathed most of his $2 million estate to the university. A member of the class of 1904, he left school before graduating to support his parents, and later went on to success in the lumber business. Prior to 1969, Stanford played at the Old Pavilion, opened in 1922. Maples is home to multiple Stanford Cardinal athletics teams, including men's and women's basketball, men's and women's gymnastics, and women's volleyball. The raucous student section that roots for the men's basketball team is called the "6th Man" and is located in several rows courtside. Prior to the renovation, t ...

Stanford University
Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California. The campus occupies , among the largest in the United States, and enrolls over 17,000 students. Stanford is considered among the most prestigious universities in the world. Stanford was founded in 1885 by Leland and Jane Stanford in memory of their only child, Leland Stanford Jr., who had died of typhoid fever at age 15 the previous year. Leland Stanford was a U.S. senator and former governor of California who made his fortune as a railroad tycoon. The school admitted its first students on October 1, 1891, as a coeducational and non-denominational institution. Stanford University struggled financially after the death of Leland Stanford in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, provost of Stanford Frederick Terman inspired and supported faculty and graduates' entrepreneu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dick's Picks Volume 24
''Dick's Picks Volume 24'' is the 24th installment of the popular Grateful Dead archival series. It contains selections from the March 23, 1974 concert at the Cow Palace in Daly City, California. The two-disc, vault release is mastered in HDCD. This was a significant show in Dead history, being the first to use an essentially complete version of the Wall of Sound setup. A short-lived sound system, it was diminished after less than two years due to high maintenance, transportation and assembly costs. They began work on it in 1973 and smaller versions of the system were used right up until this show. Also featured are the first performances of " Scarlet Begonias" and "Cassidy". Enclosure, liner notes, and article The release includes two sheets of paper stapled together in the middle, yielding an eight-page enclosure that slides out of the case, enabling its front page to also function as the CD's cover.

Winterland Ballroom
Winterland Ballroom (more commonly known as Winterland Arena or simply Winterland) was an ice skating rink and music venue in San Francisco, California. The arena was located at the corner of Post Street and Steiner Street. It was converted for exclusive use as a music venue in 1971 by concert promoter Bill Graham and became a common performance site for many famous rock artists. Graham later formed a merchandising company called Winterland Productions which sold concert shirts, memorabilia, and official sports team merchandise. Origins The venue was opened on June 29, 1928, as the ''New Dreamland Auditorium''. It served as an ice skating rink that could be converted into a seated entertainment venue. Sometime in the late 1930s the building's name was changed to ''Winterland'', and it successfully operated through the Great Depression. It was built in 1928 for $1 million (equivalent to $ million in ). The New Dreamland was built on the site of the Dreamland Rink (midway on the ...
