He would then do the final assembly bonding a lathe cut acrylic center and a foam pad and packaging by hand.

One of the main design revisions, required was a series of 'ribs' on the underside of the platter to prevent warping from the extreme changes in temperature during the manufacturing process. A raised barrier was also added to contain the head in the event of miscuing and a polished surface inside the barrier to minimize damage to the stylus. Due to its limited manufacturing run the SX2 has become a sought after rarity among pro DJs. From Wikipedia, the free encyclopedia.

Safe Shopping Guarantee. High frequency hiss is generated as the stylus rubs against the vinyl, and dirt and dust on the vinyl produces popping and ticking sounds.

The latter can be reduced somewhat by cleaning the record before playback. Due to recording mastering and manufacturing limitations, both high and low frequencies were removed from the first recorded signals by various formulae. With low frequencies, the stylus must swing a long way from side to side, requiring the groove to be wide, taking up more space and limiting the playing time of the record. At high frequencies, hiss, pops, and ticks are significant.

These problems can be reduced by using equalization to an agreed standard. During recording the amplitude of low frequencies is reduced, thus reducing the groove width required, and the amplitude at high frequencies is increased.

The playback equipment boosts bass and cuts treble so as to restore the tonal balance in the original signal; this also reduces the high frequency noise. Thus more music will fit on the record, and noise is reduced. The current standard is called RIAA equalization. It was agreed upon in and implemented in the United States in ; it was not widely used in other countries until the s. Before that, especially from , some different formulae were used by the record manufacturers.

In Joseph P. Maxwell and Henry C. Harrison from Bell Telephone Laboratories disclosed that the recording pattern of the Western Electric "rubber line" magnetic disc cutter had a constant velocity characteristic.

This meant that as frequency increased in the treble, recording amplitude decreased. Conversely, in the bass as frequency decreased, recording amplitude increased. Otherwise, bass modulation became excessive and overcutting took place into the next record groove. When played back electrically with a magnetic pickup having a smooth response in the bass region, a complementary boost in amplitude at the bass turnover point was necessary.

Miller in reported that when complementary boost at the turnover point was used in radio broadcasts of records, the reproduction was more realistic and many of the musical instruments stood out in their true form.

West in and later P. This meant that the electrical recording characteristics of Western Electric licensees such as Columbia Records and Victor Talking Machine Company in the era had a higher amplitude in the midrange region.

Brilliance such as this compensated for dullness in many early magnetic pickups having drooping midrange and treble response. Over the years a variety of record equalization practices emerged and there was no industry standard. Evidence from the early technical literature concerning electrical recording suggests that it wasn't until the — period that there were serious efforts to standardize recording characteristics within an industry.

Heretofore, electrical recording technology from company to company was considered a proprietary art all the way back to the Western Electric licensed method used by Columbia and Victor. Broadcasters were faced with having to adapt daily to the varied recording characteristics of many sources: various makers of "home recordings" readily available to the public, European recordings, lateral-cut transcriptions, and vertical-cut transcriptions.

The NAB, among other items, issued recording standards in for laterally and vertically cut records, principally transcriptions.

When the record was played back using a complementary inverse curve, signal-to-noise ratio was improved and the programming sounded more lifelike.

The authors disclosed electrical network characteristics for the Columbia LP curve. This was the first such curve based on formulae. This was intended for use by hi-fi amplifier manufacturers. If records were engineered to sound good on hi-fi amplifiers using the AES curve, this would be a worthy goal towards standardization.

Besides also being a battle of disc size and record speed, there was a technical difference in the recording characteristics. Ultimately, the New Orthophonic curve was disclosed in a publication by R. Moyer of RCA Victor in He traced RCA Victor characteristics back to the Western Electric "rubber line" recorder in up to the early s laying claim to long-held recording practices and reasons for major changes in the intervening years. It eventually became the technical predecessor to the RIAA curve.

Hence the RIAA curve did not truly become a global standard until the late s. Further, even after officially agreeing to implement the RIAA equalization curve, many recording labels continued to use their own proprietary equalization even well into the s. Overall sound fidelity of records produced acoustically using horns instead of microphones had a distant, hollow tone quality.

Some voices and instruments recorded better than others; Enrico Caruso , a famous tenor, was one popular recording artist of the acoustic era whose voice was well matched to the recording horn. It has been asked, "Did Caruso make the phonograph, or did the phonograph make Caruso?

Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism.

There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.

Electric recording which developed during the time that early radio was becoming popular benefited from the microphones and amplifiers used in radio studios. The early electric recordings were reminiscent tonally of acoustic recordings, except there was more recorded bass and treble as well as delicate sounds and overtones cut on the records.

This was in spite of some carbon microphones used, which had resonances that colored the recorded tone. The double button carbon microphone with stretched diaphragm was a marked improvement. Alternatively, the Wente style condenser microphone used with the Western Electric licensed recording method had a brilliant midrange and was prone to overloading from sibilants in speech, but generally it gave more accurate reproduction than carbon microphones. It was not unusual for electric recordings to be played back on acoustic phonographs.

The Victor Orthophonic phonograph was a prime example where such playback was expected. In the Orthophonic, which benefited from telephone research, the mechanical pickup head was redesigned with lower resonance than the traditional mica type.

Also, a folded horn with an exponential taper was constructed inside the cabinet to provide better impedance matching to the air. As a result, playback of an Orthophonic record sounded like it was coming from a radio.

Eventually, when it was more common for electric recordings to be played back electrically in the s and s, the overall tone was much like listening to a radio of the era. Magnetic pickups became more common and were better designed as time went on, making it possible to improve the damping of spurious resonances.

Crystal pickups were also introduced as lower cost alternatives. The dynamic or moving coil microphone was introduced around and the velocity or ribbon microphone in Both of these high quality microphones became widespread in motion picture, radio, recording, and public address applications. Over time, fidelity, dynamic and noise levels improved to the point that it was harder to tell the difference between a live performance in the studio and the recorded version.

This was especially true after the invention of the variable reluctance magnetic pickup cartridge by General Electric in the s when high quality cuts were played on well-designed audio systems. There were important quality advances in recordings specifically made for radio broadcast.

The intent of the new Western Electric system was to improve the overall quality of disc recording and playback. The newly invented Western Electric moving coil or dynamic microphone was part of the Wide Range System. It had a flatter audio response than the old style Wente condenser type and didn't require electronics installed in the microphone housing. Signals fed to the cutting head were pre-emphasized in the treble region to help override noise in playback.

Groove cuts in the vertical plane were employed rather than the usual lateral cuts. The chief advantage claimed was more grooves per inch that could be crowded together, resulting in longer playback time.

Additionally, the problem of inner groove distortion, which plagued lateral cuts, could be avoided with the vertical cut system. Wax masters were made by flowing heated wax over a hot metal disc thus avoiding the microscopic irregularities of cast blocks of wax and the necessity of planing and polishing.

Vinyl pressings were made with stampers from master cuts that were electroplated in vacuo by means of gold sputtering. Amplifiers and cutters both using negative feedback were employed thereby improving the range of frequencies cut and lowering distortion levels. Radio transcription producers such as World Broadcasting System and Associated Music Publishers AMP were the dominant licensees of the Western Electric wide range system and towards the end of the s were responsible for two-thirds of the total radio transcription business.

Developmentally, much of the technology of the long playing record, successfully released by Columbia in , came from wide range radio transcription practices. Goldmark, Rene' Snepvangers and William S. Bachman in made it possible for a great variety of record companies to get into the business of making long playing records. Radio listeners heard recordings broadcast and this in turn generated more record sales.

The industry flourished. Technology used in making recordings also developed and prospered. There were ten major evolutionary steps that improved LP production and quality during a period of approximately forty years.

At the time of the introduction of the compact disc CD in , the stereo LP pressed in vinyl was at the high point of its development. Still, it continued to suffer from a variety of limitations:. Audiophiles have differed over the relative merits of the LP versus the CD since the digital disc was introduced. Modern anti-aliasing filters and oversampling systems used in digital recordings have eliminated perceived problems observed with very early CD players.

There is a theory that vinyl records can audibly represent higher frequencies than compact discs, though most of this is noise and not relevant to human hearing. Due to the distance required between grooves, it is not possible for an LP to reproduce as low frequencies as a CD. High frequency sensitivity decreases as a person ages, a process called presbycusis.

For the first several decades of disc record manufacturing, sound was recorded directly on to the "master disc" at the recording studio. From about on earlier for some large record companies, later for some small ones it became usual to have the performance first recorded on audio tape , which could then be processed or edited, and then dubbed on to the master disc.

A record cutter would engrave the grooves into the master disc. Early versions of these master discs were soft wax , and later a harder lacquer was used. The mastering process was originally something of an art as the operator had to manually allow for the changes in sound which affected how wide the space for the groove needed to be on each rotation. As the playing of gramophone records causes gradual degradation of the recording, they are best preserved by transferring them onto other media and playing the records as rarely as possible.

They need to be stored on edge, and do best under environmental conditions that most humans would find comfortable. Where old disc recordings are considered to be of artistic or historic interest, from before the era of tape or where no tape master exists, archivists play back the disc on suitable equipment and record the result, typically onto a digital format, which can be copied and manipulated to remove analog flaws without any further damage to the source recording.

For example, Nimbus Records uses a specially built horn record player [88] to transfer 78s. Anyone can do this using a standard record player with a suitable pickup, a phono-preamp pre-amplifier and a typical personal computer. However, for accurate transfer, professional archivists carefully choose the correct stylus shape and diameter, tracking weight, equalisation curve and other playback parameters and use high-quality analogue-to-digital converters.
